Microphone Connections : Microphones can be connected directly to the XLR connectors.

Other Audio Connections : For all other connections you need to make an adaptor cable to the multipin connectors. Please refer to the Pin assignment at the end of this document.

Sync Connections : Two BNC connectors are provided for Sync connection to and from the MIX4. The MIX4 takes Word Clock, AES sync and video sync (if the optional sync board is installed) and synchronizes all internal timing to one of these references if instructed by the system Setup software. The sync output provides synchronous Word Clock.

GPI / O Connections : A 15 pin Sub-D connector is provided for connecting external devices for parallel remote control.

Important note! Theses inputs are TTL type and should not exposed by external voltage in excess of +5V. Ethernet Connector :

The Ethernet connector allows to hook up the MIX4 to a 10/100Mbit/s (auto negotiation) network. It complies with CAT5. This interface is provided for external communication by TCP/IP protocol. It allows to set up the MIX4 over the network. One other typical application is the remote control of a station router.

MIX4 Principle Functions

The Junger MIX4 is a Digital Audio Mixer with 4 stereo full-featured Channel Strips. The MX4 has 4 independent stereo mix busses, each of which can be independently configured :

Mix The Bus works as an ordinary stereo mix bus Mix Minus Actually the same as a Mix config, but you don’t route one or more Strips to it. PreMix The bus is used as a prefade Aux send. PostMix The bus is used as a postfade Aux send. Direct Out A prefade send from one and only one strip is routed to the bus.

Each of the 4 Channel Strips of the MIX4 can be connected to one of the 14 inputs (sources).

Sources 1 and 2 are normally used for microphones but can be used for analog line level signals.

All other inputs are two channel sources and therefore they can carry two channel and stereo signals as well.

The settings of each Channel Strip are controlled and stored to the relating source it is conn ected to. The bus outputs are available in both analog and AES digital. Please see the block diagram below :

Also a sophisticated talkback system is provided by the MIX4 that can operate local talkback and remote talkback. It also allows talking to the busses. Besides the 4 bus line outputs (analog and digital) there are two auxiliary outputs AUX1 (digital) and AUX2 (analog), which can be used for external metering, talkback, extra PFL output or other purposes as you require.

Jünger Audio-Studiotechnik GmbH

The signal available at these outputs is determined by the set up software :

The Setup software is an important part of the system because it allows for offline configuration of the MIX4 to fit it in almost every production environment from Edit Workstation to On Air. It serves for general settings a user is not allowed to change from the desktop remote.

For remote control purposes the MIX4 is equipped with 8 tally outputs and 6 GPI inputs with TTL levels. Their functions will be set by Setup software as well.

In addition, a TCP/IP over Ethernet interface allows the remote control of external routers via TCP/IP as well as the centralized use of the setup software and the operator/preset/backup/restore tool over the network.

There is also a serial interface for connection to a PC via RS 232 that serves for configuration of the MIX4. This interface may also be used in RS 422 mode.

Management of MIX4 settings

The initial settings such as GAIN, PAN and bus assignment of a source are done within a channel strip. Those parameters are always stored in relation to the source, i.e. if you select a specific source again on for a channel strip, the parameters stored will automatically be activated.

The filter and dynamic settings are also set up by a channel strip. These settings are called DSP parameters. You can save the DSP parameters (Phase, HP, 3xEQ, De-Esser, Expander, Compressor) to presets. Later on you can load the data of such presets into any channel strip. When loading a preset, the parameters will be applied to the source that is selected for that channel strip and will stay with that source.

As mentioned above, the MIX4 manages all parameters relating to a source. Therefore each source keeps its DSP parameters even if you do not use it momentarily for a channel strip.

Important note : The data of presets will be applied in the same way as one would input it manually step by step. It means that changing preset data later on will have NO effect for a source where that preset has previously been used!

You can edit preset parameters off line by a PC based operator/preset/backup/restore tool. There you can also give it a name. You can store sets of presets into files and/or send parts or all of it to devices of your choice. Finally you can load a preset remote controlled into one or many channel strips.

The MIX4 has 11 areas for user data, called operators. For each of the 11 operators there are 8 Snap-Shots. They contain the actual source assignment with all parameters as well as the settings done in the <MON> menu from the desk top remote. Each operator can have one set of monitor sources applied to the user buttons 1-4. By using the setup software you can name the operators and apply individual security settings including a 4 digit PIN. This allows you to deny operators access to several functions of the desktop remote and thereby prevent inexperienced personal making operational mistakes. If you do not assign a PIN for an operator (0-0-0-0) the login happens without interrogation. On logout all current settings of an operator are stored automatically.

An exception is the 1

operator named „Guest“. He will always be activated when you turn the MIX4 on. This ensures that everybody can work with the MIX4 without being a registered operato r. Therefore no lo gin is necessary. That is why you must store the settings which are to be loaded when you switch the unit on by a special routine. You must press the buttons <USER> first and <no label> afterwards. The message “Operator save“ will be displayed.

The data of the operators (content of their snap shots and last active conditions) can be managed with the operator/preset/backup/restore tool. With this you can create sets of 10 operators ea ch and store these in files at any place in the network and/or send them to devices. This tool allows you to create a backup for a set of operators and load it later on into a similar device. You can also login individual operators over the network.

Finally you can manage a set of all the data of a device. You can back it up and restore it later on. This function may ease the exchange of units in the field without restoring setups, operator profiles and presets but back up the unit at once.

MIX4 Display System

The Mix 4 is based on a configurable hardware architecture that allows for multiple settings and configurations. This way the MIX4 can be setup for different working environments and be tailored to the individual user via Mix 4 Setup software that runs on a PC.

The configurable hardware centers around 4 Channel Strips labeled A, B, C, D, each with a fader, Channel Button, Rotary Knob (a continuous turn encoder), and a two line 8 character display, with characters screened on the front panel above the top line as shown here :

L C R 1 2 3 4 L C R 1 2 3 4 L C R 1 2 3 4 L C R 1 2 3 4

M i c 1 T e l e f o n C D 3 J i n g l e 1

The lower line displays the actual source name. As needed, characters in the top line of these displays are turned on, to ‘point’ to the legends

(L, C, R, 1, 2, 3, 4) screened on the panel just above the top row of the display :

L C R 1 2 3 4 L C R 1 2 3 4 L C R 1 2 3 4 L C R 1 2 3 4

M i c 1 T e l e f o n C D 3 J i n g l e 1

During normal operation, the Mix 4 is in the MIX mode – i.e. no SETUP Button, as shown above, on the remote is activated. While in MIX mode, the Output bus routing for each Channel Strip is displayed by small symbols in the upper line pointing at the legends on the panel.

Screened legend 1 - 4 (number of the MIX busses) :

- assignment to a Mix bus (respective source must not be assigned for a Mix Minus bus)

^ - assignment to a Direct Out bus (only one source per Direct Out)

- this bus is configured as Pre- or Postfade AUX Mix and therefore routing is via the Aux Level control (Pre- or Postfade depending on the Bus Mode)

At the same time, on the left end of the top line of the display, the nature of the source for the Channel Strip is shown : Screened legend blank, L, C, R :

blank L - the source of the MIX4 Channel Strip is two channel where the actual audio signal is derived from the left channel C - the source of the MIX4 Channel Strip is stereo but has been turned into mono (L + R - 3dB) or a MIC signal is assigned that is a mono signal by definition R - the source of the MIX4 Channel Strip is two channel where the actual audio signal is derived from the right channel

Operation

When switched on, the MIX4 starts up in the Mix mode :

Depending on the Setup, the Channel Buttons are PFL / MUTE / START or HYBRID and the Channel Rotary knob acquire a GAIN / PAN / BALANCE / Prefade or Postfade function.

Turning a Channel Rotary Knob changes the gain of the respective MIX4 Channel Strip by +

15dB, as shown

here for Channel Strip B (#2), with the GAIN set to +6 dB :

Important note! After two seconds of no turning of the knob, the display changes back to the Mix mode display, like the other three Strips show in this example.

PAN / BALANCE mode :

A push on the Channel Rotary Knob switches it to the PAN / BALANCE mode.

When a mono source - underlined L or R or C - is assigned to the MIX4 Channel Strip it is a PAN function (This might be used when you have say two microphones in an interview situation, with one panned to the left, the other to the right).

When a stereo source - L or R or C not underlined - is assigned, a BALANCE control is performed.

Prefade / Postfade Send Levels :

When one bus or more buses are configured as Prefade mix or Postfade mix and the respective BusMonitor button is pressed then the top display line shows level of each channel to the mix, e. g. <Bus 3>

L C R 1 2 3 4 L C R 1 2 3 4 L C R 1 2 3 4 L C R 1 2 3 4

P r e F a d e r M i x B u s 3 o f f - 1 0 , 0 d B o f f + 3 , 0 d B

The Mic 1 is currently not yet assigned to Prefade bus3, and by turning the Channel Rotary Knob A it is included in the mix with -83 dB and can be modified by further turning the Channel Rotary Knob by up to +10 dB.

Important note! This display is left by pushing another Bus Monitor button.

Button operations :

Buttons which control external devices or perform PFL or DIM can operate in two different modes: Toggle switch operation If one presses the button once briefly the function will be turned on If one presses the button once briefly again the function will be turned off Push button operation If one presses and holds the button the function will be turned on If one releases the button the function will be turned off

Shortcuts :

For quick access to the first eight Presets or one of the 8 Snap-Shots there is a shortcut function implemented. Pressing the <DSP> button first and one of the <USERx> or <BUSx> buttons afterwards loads the respective Preset into the Channel Strip which has been pre selected by the setup softwa re. Pressing the <USER> button first and one of the <USERx> or <BUSx> buttons afterwards loads the respective SnapShot.

N-1 busses :

The MIX4 knows one N-1 bus configuration to operate a telephone interface. This function is called HYBRID (s. p. 57). All other N-1 configurations must be set manually.

PFL modes :

The MIX4 has exclusive and summing PFL functions that can be turned off and on automatically, depending on the fader position (s. p. 20).

Test tone generator :

For testing purpose of outgoing lines you can route a 1kHz test tone to the busses of the MIX4 (s. p. 20). The level of that signal can be set from the desktop remote.

Monitor section :

The 4 busses of the MIX4, sources (MIX4 inputs) assigned to Channel Strips and those not assigned to a Channel Strip can be monitored via the monitor root (functions called: bus monitoring, PFL and source monitoring). The monitor line output and two parallel headphone outputs are connected to that root. Both headphone outputs together and the monitor line output have level controls to set the monitoring loudness. Two auxiliary outputs (analog and digital both 2CH) may also be connected to the monitor root by use of the setup software (e.g. to connect an external meter to the MIX4). The LED level and phase display has only effect for bus monitoring and for PFL. It is not active for source monitoring.

<SRCE> Source Selection

Here you define the source for the respective Channel Strip of the MIX4. The MIX4 differentiates between :

2-channel sources (L

or R underlined in the display at the top of the Strip) stereo sources (without labeling). mono sources (C

underlined)

When a Channel Strip’s input is setup for a 2-channel source (i.e. the 2 channels are independent, not an LR pair), then either of the 2 inputs can be selected as a source for a Strip, sending the same signal out of the Strip to the L and R sides of the stereo busses. This function can be assigned permanently by Setup software to every input. The Setup option is called “force 2Ch”.

After pressing <SRCE>, you then push the channel button of the Strip where you want to change the input source. In the example below, we are changing the input source for Strip B (#2). After pushing the Channel Button on Strip B, the Strip’s display will show the status of that source in the top line and, the source name (assigned using the Setup software on the PC) on the bottom line.

Pushing the Channel Rotary Knob switches the source selection to 2-channel mode

and will select the LEFT channel. Repeated pushing - called “3 push”

leads to RIGHT channel and back to STEREO mode and so forth.

You may also select the opposite channel via “3 push” by pressing the Channel Rotary Knob several times or by the standard turning function of that knob.

Important Note!

Stereo / 2-channel switch over is only possible via pressing of the Channel Rotary Knob.

While source selection is possible by either turning or pushing the Rotary Knob. If in continuous operation for 2-channel mode the content of the channels has changed (u sually happens

with VTRs when voice on track one and clean feed on track two or vice versa) you can quickl y switch to the other channel by pressing <SRCE> and then the respective channel rotary knob. The underscore in the upper line of the display changes from L

to R respectively (or vice versa).

If a stereo source is selected for that Channel Strip, pushing the Channel Rotary Knob alternates between :

mono (L+R -3dB) marked by an underscore under C and stereo (without underscore).

Pushing <SRCE> again terminates the source selection.

Router Tie Line Inputs It is possible to configure Mix 4 line inputs to be connected to Tie Lines, which in turn are connected to an

external router. This router can then be controlled by the Mix4 to allow selections of its inputs to be routed to the Mix 4 Inputs.

If the MIX4 is connected with an external router, special MIX4 firmware to interface to the control system of that router must be installed and activated in the MIX4.

The first time you dial up one of these tie line inputs on the Mix4, the display will show both names preset in Setup software and the Channel Button will start blinking green/yellow to show this special situation :

Pressing that Channel Button will give you control of the external router so you can select the desired input for the MIX4. The channel button will blink yellow or yellow/red to indicated that you are controlling the external router. By turning the Rotary Knob one will select router sources (blinking yellow) or groups of sources (blinking yellow/red) first, depending on the external router brand / type :

The top line now shows the group name and the bottom line now shows the source name of the selected source of the external router. The selected source will be available for that input (and therefore for the Channel Strip of the MIX4) immediately.

Pushing the Channel Button again will switch back to initial source selection mode and the LED of the Channel Button will turn off. In this case the display will show the name of the tie-line again not the name of the router source! But if you push <SRCE> instead of the channel button at this time the display will show the router source name.

If router sources are organized in groups that second push will lead one level down to sele ct a source within a pre-selected group (see above). In this case the channel button will blink yellow now to indicate that turning the Rotary Knob will now select a source from that group.

Pushing <SOURCE> will terminate the function.

Notes about different control concepts for router from different manufactures :

Klotz VADIS II

In this case, 16 sources for each MIX4, connected to a VADIS system, must be pre-selected in within the “Junger Audio DDE client” (see extra description for VADIS operation). Thus you will get 16 more (external) sources for the MIX4.

LAWO / Mandozzi / DHD

By use of Setup software, 16 groups by 8 sources can be pre-selected for the respective system which the particular MIX4 can select afterwards. There are two levels of controlling such a router. One needs to select one of the groups first and afterwards one of the sources from that group.

page 14

Jünger Audio-Studiotechnik GmbH

Important note! When you are selecting an external source for the MIX4

(see above) there are two ways to leave this mode (see 4.1 or 4.2 below) :

0. Turn source selection mode on by pressing the <SRCE> button.

1. Select a Channel Strip where you want to assign an external source to.

Press a Channel Button - Channel Button is blinking green.

2. Search for an input (tie line) that is connected to an external router destination port.

Turn the Channel Rotary Knob until - Channel Button is blinking green / yellow.

3. Turn external control on.

<BUS> Assignment and Bit Transparent Mode

This is where you route the output of a MIX4 Channel Strip to one or more of the possible buses. Possible buses here are the Mix bus, the Hybrid bus (a function to operate a telephone hybrid that also

means a Mix Minus or clean feed to that bus) and the Direct Out bus.

You do not need to define Mix Minus busses – just don’t assign one or more sources to bus and voila – you have a mix minus!

Why make a Mix Minus? Perhaps to prevent feedback or to keep a source out of headphones. If you later call such source again the bus assignment will be preserved because the MIX4 “remembers” all source related settings.

Special Bus Notes :

In general for the same stereo source the bus assignment is the same in different Channel Strips. If one source is set for 2-channel mode it can have different bus assignments in different channels

. The initial bus assignment is taken from the previous stereo setting When changing that source back to stereo, the bus assignment will be taken from the left channel.

Generally, after pushing <BUS> you press the Channel Button in which the bus assignment is to be changed – channel C for this example. After pressing the Channel Button on C, the display in this Channel Strip will show a small triangle which can be moved below the numbers 1 - 4 by the Channel Rotary Knob :

L C R 1 2 3 4 L C R 1 2 3 4 L C R 1 2 3 4 L C R 1 2 3 4

PFL

To select a bus to route to from C, point at it with the arrow and then push the Channel Rotary Knob.

Buses that are configured as Prefade / Postfade are marked in the display by a small ’x’ and cannot be selected by the ‘arrow’. Channels are always assigned to these busses. The Cha nnel Rotary Knob (Aux Send) on each channel adjusts the send level to the busses anywhere from ‘Off’ (AKA ‘not routed’) to +10 dB.

Buses that were configured for Direct Out can “route out“ only one source. Such a bus is marked by a tip to the top. There always the last selected MIX4 Channel Strip (and thus the assigned source) is “routed out”.

The <BUS> button also allows for set up of the Bit Transparent Mode, i.e. data put through from a source to a bus output. In this case the bus can not be monitored to avoid unexpected high levels from data signals. The respective analog output will be muted while the source label changes to DATA and PFL function is turned off for such a source. After pressing <BUS> you must press the <no label> button :

L C R 1 2 3 4 L C R 1 2 3 4 L C R 1 2 3 4 L C R 1 2 3 4

<DSP> Parameter

Here you control the filters, Eqs, and the dynamics section of each Channel Strip. Generally, after a push on <DSP> you then press the Channel Button of that Channel Strip for which you

want to change settings. Important note! If PFL is already activated before pressing <DSP>, you be adjusting the DSP settings while

in PFL mode, rather that while listening to the BUS monitor. For this example channel button B is pressed.

The knobs and displays on all the Strips will now be used to adjust DSP settings on B.

The display shows the selected parameter for DSP processing section in the bottom line of Channel Strip A (PHASE is first parameter offered for adjustment).

In channel D one can turn the whole DSP function on and off ’BYPASS’ by pressing Channel Rotary Knob D :

<MON> Monitoring Feature

This function allows the assignment of sources to the individual buttons of the MIX4 for monitoring purposes. Sources that are not in use on MIX4 Channel Strips can be monitored in this way.

Important note! Because this monitor signal is not processed by the DSP, no GAIN / PAN / BALANCE or DSP is possible. You will be listening to the ‘raw’ input signal.

Furthermore, here one can set both the offset gains of the two headphone outputs and the gai n of the talkback source and the PFL modes as well as the 1kHz test tone generator.

Pushing the <MONITOR> button leads to the following display :

L C R 1 2 3 4 L C R 1 2 3 4 L C R 1 2 3 4 L C R 1 2 3 4

T A L K B A C K H - P H O N E 1 E x c l P F L G E N : o f f G A I N + 0 G A I N - 0 - 2 2 d B

The respective Channel Rotary Knob determines the gain for the corresponding output. On Channel Strip B both headphone gains may be changed.

Pushing <MONITOR> again terminates these setting function. In Setup on the PC it is possible to allocate buttons on the console for source monitoring.

To assign sources to these, first press <MON> and one USER button afterwards.

The button that is actually programmed blinks yellow. The display of Channel Strip A will now show the number of such button.

Assignment of monitor sources is performed by Rotary Knob of Channel Strip B. Its display will show the source status and the source label of selected input :

L C R 1 2 3 4 L C R 1 2 3 4 L C R 1 2 3 4 L C R 1 2 3 4

As you use the knob on B to ‘dial through’ each possible source, you will hear them in turn on the monitor. When you get to the one you want, select another button to be programmed or simply press <MON> again.

If you dialup an input of MIX4 that is connected to an external router the monitor source selection is performed as explained in section <SOURCE> selection for a Channel Strip.

If there is no Tie Line available for monitoring purposes (i.e. if all available Tie Lines are routed to Channel Strips) only the router source selected for a specific Channel Strip will be available in parallel for monitor function, since source assignment to a Channel Strip has priority over monitor assignment.

If you want to dedicate a router Tie Line for monitoring purposes

Excl PFL : FdrOff If one opens the fader PFL will turned off and will stay off. Excl PFL : FdrOffOn If one opens the fader PFL will turned off and on again if fader is closed.

Sum PFL : blank Summing PFL - pressing PFL button will add that Channel Strip to the PFL bus. Pressing the button again will take that Channel Strip away from the PFL bus. Sum PFL : FdrOff If one opens a fader summing PFL will be turned off and will stay off. Sum PFL : FdrOffOn If one opens a fader summing PFL will be turned off and on again if fader is closed.

1kHz Test Ton Generator

There is a test tone function available for the bus outputs of the MIX4.

On Channel Strip D one can turn the 1kHz generator function on and off by pushing the Rotary Knob. Different levels for the test tone can be selected by turning that Knob : Possible settings are : -22dFS, -20dBFS, -18dBFS, -15dBFS, -9dBFS, -6dBFS, 0dBFS

If you turn the generator on you will monitor it automatically via the monitor section of the MIX4. You can decide now on which bus output the test tone is present. Therefore you must press the respective Bus Button. This button starts blinking green as long as you press it again.

Important note! When the <MON> button is active and you press a <BUSx> button, the respective physical output (analog and digital) is switched to the generator – i.e. the MIX signal from that bus is interrupted! It is indicated by blinking green of the <BUSx> button.

<USER> Operator Management

An administrative person manages the Mix 4 with the help of the Setup software. He or she sets the device-relevant parameters like source names, offset gains, GPI/Tally functions etc., as well as Operator names and their PIN numbers.

In principle the MIX4 knows 10 Operators and one Guest. After turning power on the device is in Guest mode. If one is a registered Operator one can log in to the MIX4 and will then be forced to authorized himself by a four digit PIN-number.

When pressing the <USER> button the following display appears :

L C R 1 2 3 4 L C R 1 2 3 4 L C R 1 2 3 4 L C R 1 2 3 4

S e l e c t O p r t r 1

P r s t L o a d S n p L o a d S n p S t o r e P R E S T 1 S N A P 1 S N A P 1

“Select” indicates that you are is in the Guest area and able to select one of the 10 Operators. Turn the A knob to do so . The selection is confirmed by pressing Channel Rotary Knob A.

Next you will be asked to enter your pin number, as shown across the displays:

L C R 1 2 3 4 L C R 1 2 3 4 L C R 1 2 3 4 L C R 1 2 3 4

O p r t r 1 E n t e r y o u r P i n 0 0 0 0

Turn each Channel Rotary Knob in turn to enter the 4 digits of your PIN. Then press any of the Rotary Knobs to confirm the entry. If the PIN is correct the data of that Operator will be loaded and the display will turn back to mix mode.

Pressing <USER> again will then show this:

L C R 1 2 3 4 L C R 1 2 3 4 L C R 1 2 3 4 L C R 1 2 3 4

O p r t r 1 L o g O u t

P r s t L o A d S n p L o a d S n p S T o r e P R E S T 1 S N A P 1 S N A P 1

(The Operator can log out here by pressing Channel Rotary Knob A. You don’t want to do that now, of course!

Important note! If you want to save latest settings which are not included in a Snap Shot, be sure to log out. This will store the actual Operator data to NV memory.

page 21

Jünger Audio-Studiotechnik GmbH

Important note! If you do not log out when you ‘go home’, others can work in your area, making changes to your Setups! So when you are ready to leave the console for another Operator to take over,

be sure to Log Out. Turning the Mix 4 off and on again automatically loads the Guest Operator.

If you want to store the Guest data then before turning off power, save the Guest Operator data by first pressing <USER> and then <no label>. This will save the settings for the Guest Operator. Now if you shut off power and turn it back on, these saved Guest Operator settings will be recalled.

They will be used any time the Guest Operator is active, until the next time you update them with <USER> + <no label>.

Important note! The Setup made by the Administrator and loaded by Setup software is available to all Operators (source names, button functions, GPI/Tally settings, offset gains etc). There is no setup for

individual operators except the security settings. I.e. you must be careful when changing the general setup if operators have already stored individual settings via the desktop remote.

Snap Shots :

Each Operator has 8 SnapShots available which represent a momentary picture of the sources on the MIX4 channels with all of the relevant audio parameters.

The management of the Snap Shots is also done by pressing <USER> :

L C R 1 2 3 4 L C R 1 2 3 4 L C R 1 2 3 4 L C R 1 2 3 4

S e l E c t P r s t LoaD Snp Load O p r T r 1 P R E S T 1 S N A P 1

Turning the Channel Rotary Knob in channel D selects one of the 8 Snap Shot memories where the actual state of the MIX4 surface (sources of the MIX4 channels, their bus assignments, DSP settings as well as GAIN and PAN / BALANCE) may be stored. Pressing the rotary control D stores the data.

Loading of Snap Shot data is done in the same way :

L C R 1 2 3 4 L C R 1 2 3 4 L C R 1 2 3 4 L C R 1 2 3 4

S e l e c t P r s t L o a d O p r t r 1 P R E S T 1

Snp Load SNAP 1

S n p S t o r e S N A P 1

Turning the Channel Rotary Knob in channel C selects one of the 8 SnapShot memories from where a previous state of the MIX4 surface (sources of the MIX4 channels, their bus assignments, DSP settings as well as GAIN and PAN / BALANCE) must be loaded. Pressing Rotary Knob C loads the data.

Important note! If there are no data stored, nothing else happens but there will also be no error message. Snap Shot short cuts:

For quick access to previously stored Snap Shots a second method exists. Pressing <USER> first and one of the 4 User Buttons (for SnapShot 1 - 4) or one of the 4 Bus Buttons (for SnapShot 5 - 8) afterwards, one may load one of the 8 Snap Shots instantly.

page 22

Jünger Audio-Studiotechnik GmbH

Presets :

In addition to the Operator specific Snap Shots, there are 100 Presets which are accessible to all Operators in common.

These represent audio parameter of a single source which can be loaded into any Channel Strip to

make settings for certain narrators available for all Operators, for example. The presets have default names PREST 1 to PREST100. A preset (including preset name) can be edited by aid of a tool called Operator / Preset / Backup / Restore (OPBR).

The Preset management is done via the <USER> function as well. If the function in channel B is “PrstLoad” (preset load) a stored PRSETxxx is selected by turning Channel Rotary Knob B. Pushing one of the Channel Buttons A - D will load the selected Preset into that channel, applying it to the source assigned to that Channel Strip.

Setup of MIX4

The basic idea is that all relevant parameters that cannot be altered by MIX4 remote will be set by the Setup software. In this way the MIX4 can be adapted to various conditions and production environments.

In some installations the remote control of devices such as CD players or digital playback units is required. In other installations, people need fast and random shuffle of sources with automatic reset of all preset parameters (e.g., offset gain, EQ, dynamics, bus assignment, starting and stopping of playback devices, On Air signal activation, etc.)

All of these requirements can be configured very easily by the Setup software. In principle the MIX4 system differentiates between setting of basic functions (AKA “device parameters”) and

the settings of audio and control parameters related to the 14 possible local sources. When turning the MIX4 on for the first time it will be started with a set of standard parameters which relate to

the hardware configuration and will ensure moderate levels at the analogue outputs.

All GPI inputs and Tally outputs will be disabled. All inputs will be enabled for source selection. All inputs are in stereo mode. Both microphone inputs are set up for MIC / phantom power off All DSP parameters are set to flat (off) / Channel DSP=off All Channel Strips are assigned to BUS 1

With this, you can go ahead with some applications instantly without installing a dedicated Setup. This is the starting condition as it were so called the factory default settings. It can be recalled at any time during operation by initializing the MIX4.

By simply pressing the Setup buttons #1 <USER> and #6 <no label> buttons together.

Turning power on and off does not do this – cycling power brings things back ju st as they were stored - not initialized.

Important note! One should keep in mind that beside of the setup settings all individual operator settings will be lost if they have not yet been saved! Because the MIX4 will be reset to factory default values.

If the DSP group “hangs” and there is a malfunction of the MIX4, you should load one Operator setting because it will get all relevant settings back into the RAM of the MIX4.

For general system settings, a Setup software is part of the package. The Setup software can be installed on any standard PC running WIN 98SE or higher (XP professional is recommended).

Connection between the PC and MIX4 Base Unit is done via any of the PC’s serial port COMx or via the network. The serial transfer rate will automatically be set to 57,6kbit/s. Cable length should not exceed 10m. One can also connect the PC via a CAT5 cross over cable.

This serial connection is essential for firmware updates of the MIX4.

Important note! A firmware update is not possible over the network. Important note! If one is using his own cable it is essential to disconnect pin 8 and 9 (either by cutting

them off from a 1:1 cable or disconnecting the wires in any way). When you close the Setup software it automatically generates an INI file in the same directory to store user

specific settings.

Important note! After starting the Setup software it will be in offline mode. First of all it is required to read via “from Device” the status of the unit to work with these data.

Following all pages of the Setup software will be explained in detail :

page 24

Jünger Audio-Studiotechnik GmbH

Hardware Setup

On the Hardware page communication with the MIX4 is managed and the actual hardware configuration as well as the Device Configuration is shown. The normal procedure is to read the configuration from the connected device first and make appropriate settings from there. But one may also read a Setup from disk and send it to Device. Such Setups do not include unique information shown in the “Device Configuration” pane.

Important note! If a MIX4 is connected and you click on the GUI’s <from Device> button, the actual

parameters will be read back. Next time they will compared to the ones possibly modified. Should this action show a discrepancy an error message will appear and overwriting by mistake will be prevented.

Device Connection pane is responsible for communi cation with the MIX4

<from Device> reads parameters and settings from MIX4 <to Device> transmits such data to MIX4 <from Disk> loads a Setup from PCs hard drive <to Disk> stores a Setup to PCs hard drive “Interface: COM 1, 2, 3, 4” will select the COM port of the PC where the Setup software is running on. “TCP/IP” selects the IP address of the MIX4 one wants to communicate with. If you run the Setup

software for the first time you must enter the IP number of the MIX4 you want to talk to. If you control multiple MIX4s a list is kept in the Registry of the MS Windows OS.

Status: window shows the communication status with the MIX4

Device Configuration pane

The “MAC Address” of the Ethernet interface and the “S/N:” (serial number) are factory sttings. If the MIX4 is to be integrated into a Local Area Network (LAN) to remote control external routers, for example, you will need to give the device its own “Name:”, “IP Number:”, “Subnet Mask:” and “Gateway:”, all of which you will get from the system administrator of the organization. If not necessary you may simply leave this entry blank.

Hardware Configuration pane

“Interface 1:” / “Interface 2:” will show the installed interfaces “Video-Sync:” will show if an optional board is installed “Router-Firmware:” shows the protocol that is bound to the firmware of your MIX4

page 25

Main Setup

Sync pane

The internal sample rate or the source of synchronization will be set.

Of course it is always possible to synchronize from input one of a digital interface board or from a SDI board (very important for applications where the digital outputs of the MIX4 are routed back into a digital system).

Synchronization to an external video reference is possible. If this hardware option is installed, this feature will become available in this window.

Bus Configuration pane For each bus (mixing node) you can choose a Bus Mode

Mix regular mix mode Hybrid if the bus output is connected with a telephone interface (hybrid) Pre Fader Mix you can do a separate mix by using the channel rotary encoders Post Fader Mix you can do a separate mix by using the channel rotary encoders Direct Out the selected input (pre fader) will be put through to bus output

The 4 busses can be sent to the 4 physical (bus) outputs of the MIX4 (AES/EBU, analog, SDI embedded audio see output page for details). For special applications these (Bus) Outputs may carry different signals :

Bus the output of a mixing node Monitor you can feed the monitor root to the respective bus output PFL you can feed the PFL root to the respective bus output

This function is helpful, if you want to send the Monitor or PFL root signal to the SDI embedder or one of the other physical bus outputs of the MIX4.

Important Note! You will lose the physically bus output when selecting one

of the options (Monitor or PFL) above, but you can still monitor that bus.

The monitor buttons do not monitor the physically outputs but the mix nodes of the DSP.

Phantom: power may also be set on or off for each MIC input. Labels can also be entered for these inputs – they will be displayed on the Remote’s surface a s

discussed above.

Offset Gain: adjustment may be set in 1 dB steps. Disabled: when checked this input is not available for source selection. This is important if you are

using this particular input for Monitoring purposes only. See Monitor Setup. When these Mic inputs are assigned to Strips, the Faders on those Strips may be configured to

operate Tally controls such as machine “Start:”, “ON AIR:” lig hts, etc. The “Value:” field determines how far up the fader will be to operate the Start and/or On Air event control.

Channel Button: selections determine the action of these buttons on Strips where either MIC inputs is assigned.

PFL / MUTE / START / HYBRID

DIGITAL pane: There are 4 pairs of AES Digital Inputs to the MIX4 on the main board.

Setting options are similar to MIC inputs above with the exception of the Router check boxes

Format drop down boxes and: St. : will put the channel strip for that particular source into stereo mode. M./S. : will activate a matrix that converts M/S stereo sources into X/Y (or A/B you name it) 2Ch. : will make this input permanently available as a 2 channel source (that is, not as a stereo pair). This function is also referred to as Force 2CH.

Interface 1 / 2 pane:

There are 2 times another 4 pairs of inputs, each for the interfaces installed (only available if installed). Setting options are similar to Digital pane above.

Jünger Audio-Studiotechnik GmbH

Outputs Setup

DIGITAL Pane

Each of the 4 stereo busses of the Mix 4 has an AES Digital output. These are setup in the DIGITAL Pane of the Outputs page :

Limiter Thd: (Threshold) can be set for each limiter on the 4 busses.

These settings are shown in the Digital pane, but are BUS settings, so they affect the Analog Bus Outputs as well. The default setting is 0dBFS. See the note in the Analog Pane below.

Analog pane This lets you set the Analog Output level that corresponds to a digital level of 0dBFS. If set to +22dBu, for example, then when the digital level on the bus is 0dBFS, the level on the analog output will be +22dBu.

The Bus Limiter threshold settings (set in the Digital Pane – see above) and the analog output maximum level set in this pane allow you to fit the MIX4 to any requirement for operating level and head room.

Examples:

If you want a digital level on the bus of -18dBFS to produce an analog output level of +4dBu, then

set the Max. Analog Output Level to +22dBu.

If you want a digital level on the bus of -9dBFS to produce an analog output of +6dBu, then set the

Max. Analog Output Level to +15dBu.

In either case, the setting of the Limiter Threshold in the Digital Pane will limit the maximum level on

the bus and therefore the maximum level on the analog outputs. If for example, the bus limiter

threshold is set for -2dBFS, then in the -18 example here, the max. analog output level actually seen

on the analog output will be +20dBu, even though the max. analog output allowed was set for

+22dBu.

page 28

Jünger Audio-Studiotechnik GmbH

Headphones pane Both headphone outputs have independent amplifiers and can be adapted individually by the MIX4 remote to fit the desired listening conditions. The maximum output level can be set to +15 dBu.

The signal monitored may be selected “Fixed to” one of the “BUSses” or the “PFL” selector or to ”Follow Monitor Selection”.

The maximum possible level on the headphone outputs may be set here as well. Monitor Line Out pane

There is one stereo monitor line output for connection to a set of active speakers (maximum level + 6dBu). Setup options are the same as for Headphones except the maximum output level (+6 dBu). Scrolling down the page reveals additional panes :

Aux Out 1 (digital) pane and Aux Out 2 (analog) pane

These have source selections as above plus all sources from the input router of the MIX4. AUX 2 has a “max. Output Level” adjustment.

Important note! These are auxiliary outputs for general purpose (metering, external talkback send). Do not be confused Aux Out with the phrase “aux send” normally used for pre / post fade (aux) sends. The offset gains for all sources are not active for the “Fixed to [source x]” option. You will get the “raw” level of the selected input.

If one of the above outputs is set to “PFL” it becomes an independent PFL output. I.e. the PFL signal will only appear at that output and will be no longer part of the monitor root.

Talkback Setup

The MIX4 has 2 Talkback modes. Local pane

In daily operation Talkback will probably be one of the two microphone inputs to the Mix 4. But could also be one of the line inputs. The selection is done in the Local pane of this window. If the Talkback button is pressed this signal is routed to the Destination: output(s) which may be selected here. In addition you can specify via the Split on: options whether the Talkback signal replaces the signal that is normally present at that output or

if it should happen in so called split mode. In Split on: the Talkback signal will only be routed to the right channel so that the signal normally present can still be monitored in the left one.

Pressing the Talkback button may activate a tally that can remote control an external Talkback destination unit.

External pane

For external Talkback mode you can specify the Source: of an external signal. The Destination: of external talkback may be different from local talkback, as specified here. External Talkback may be activated by GPI.

Important note! Be careful with the external GPI. It will exchange the monitor source with the external Talkback signal input. If this GPI is permanently activated it will permanently switch Headphones or Speakers or Auxes off from monitoring, which can lead to the mistaken impression that there is no monitoring. Therefore external Talkback will always be send to it’s destination in split mode (see above).

Monitor Dim Level pane

When a Talkback is engaged, the monitor loudspeaker is dimmed by the amount set here.

Dim button pane The Mix 4 Remote surface has a DIM Button. The actual action of this DIM button is set to one of these 4 options:

DIM the monitor MUTE the monitor MUTE MIC 1 MUTE MIC 2 to perform a cough function.

Tally (GPO) setup

For many installations, Tally (GPO) outputs are necessary to remote control external devices or to signal conditions such as On Air. from HW revision 4 of the base unit, the physical outputs are relay contacts (see pin assignment and electrical specs).

The MIX4 has 8 Hardware Tally (GPO) outputs - HTally 01 to HTally 08 There are 8 rows in this pane for Hardware Tally setup. HTally 01 is typical of the 8 in the hardware group. Here will be distinguished whether it will be a static signal NC (normally closed) / NO (normally open)

or if it is a 100ms pulse

Signal Type

Static + / Staic - NC / NO Start + / Start - 100ms puls NO / 100ms puls NC Stop + / Stop - 100ms puls NO / 100ms puls NC

For each Tally one of the predefined types can be selected :

Tally Type

OFF FaderStart ButtonStart Event Hybrid Button+FaderStart

Finally the triggering source (related to one of the MIX4 inputs) or the triggering event must be selected :

Event

On Air Talkback Lim A, B, C, D, Lim All USERx button BUSx button

A scratchpad for making notes regarding external connections rounds up this set up area.

Jünger Audio-Studiotechnik GmbH

GPI Setup

If functions of the MIX4 are remote controlled one can make use of GPI inputs. There are 6 hardware GPIs by optical couplers driven by a current source available (see pin assignment and electrical specs) The expected type of signal can be selected here :

Signal Type

Low-Active input voltage > 3V High-Active input voltage < 3V

Important note! Keep in mind that the GPI inputs are optical couplers (in line with a current source to protect the optical couplers). If the input voltage is less than 3V an internal pull up resistor will keep the MIX4 logic input high, e.g. if you want a “High-Active” switching you must feed the input by a voltage higher than 3V while the voltage must become less than 3V for the switching event.

Here one must select an Event Name to which the MIX4 can allocate the relevant command :

OFF Monitor Dim will dim the monitor line out by a pre set value (see T

alkback page) Monitor Mute will mute the monitor line out Ext. Talkback will activate External Talkback function Mute Mic1 Mute Mic2 Cut A, B, C, D will mute respective Channel Strip Hybrid Call waiting input from a telephone hybrid User Button 1, 2, 3, 4 will activate respective User Button (pre selected function see D

esktop-Unit) Preset1 -> Ch.A will load PresetX into Channel Strip Ch.Y Preset1 -> Ch.B and …………….. so Preset8 -> Ch.D forth

A scratchpad is also available here so one cannot lose one’s NOTES.

Desktop-Unit Setup

Individual functions can be assigned to most buttons of the MIX4 remote control which often maybe bound up with Tally functions (see Tally page). User Buttons pane

The 4 User Buttons can have these functions :

Source Monitor assign a source for monitoring purpose (no meter, no offset gain) Talk to Hybrid enables a n independent way to talk directly to a telephone Monitor LL sends the left monitor signal to both speakers Monitor RR sends the right monitor signal to both speakers Output x Off turns the related physical bus outputs off Mon-Split BUSx splits the monitor signal in BUSx (right channel) and PFL (left channel) Event can have Event trigger function with 3 different colors (green, red, yellow)

Important note! The Event function is not implemented for external trigger via GPI! Bus Buttons pane

The Bus Buttons have Bus Monitor and Event (indicated green) functions only for now.

Router Setup

The MIX4 allows the remote control of external routers. If this function is installed and enabled you need to enter all relevant settings in this R

outer page.

Protocol: will display the external router version installed bound to the current firmware. The MIX4 can only

use one protocol at a time. Therefore a protocol change requires a firmware change. External Router control is a software option, requiring an Activation Code: which you will receive from

Junger with your order. It should be entered here and the Activate soft-button must be pressed afterwards. The principal function will be explained in reference to the Klotz VADIS II system. It requires the Junger DDE client to be installed on the VADIS PC. For details pls. refer to the section :

Junger Audio DDE client for VADIS II.

You also need to define the IP Number: of the router server application and its port number. For VADIS II operation there are 8 MIX4s possible at the same time each one defined by a number from 1 to 8 set in the MIX4-ID: box.

If one has enabled sources of the MIX4 which are connected to a router by Tie Lines for router operation, (see S

ources page) the MIX4 performs a log in to the router over the LAN while power up to check

communication. If this log in fails for any reason it will be displayed by :

ROUTER

CONNECT ERROR

This indicates that there is a network problem that needs to be solved. Because this is some kind of an initial function you need to find the reason for the error (no network cable connected somewhere in chain, DDE client not up and running, etc.).

The MIX4 will log in each time one presses the <SRCE> button or one of the User Buttons if router monitor is assigned. If meanwhile a system problem occurred and log in fails for any reason the message : Connect : Error appears in the particular Channel Strip display.

page 34

Jünger Audio-Studiotechnik GmbH

Operator/Security Setup

For those who do not want to work wit multiple operators may: Disable Operator Management at all. Each of 10 Operators can have his/her own, individual settings.

The Operator list box is editable, so you can enter a name for each Operator : Morgan in this case. Each operator can have a 4 digit PIN: assigned (default 0-0-0-0).

The name of the currently selected Operator will appear in the display of the MIX4.

If no PIN is assigned there will be immediate log in for such an operator.

Certain functions of the MIX4 can be locked out, preventing their use or operation. These are selected for a given operator using the : Lock Function pane

A special function is the initialization of the MIX4. When updating the firmware we recommend to initialize the unit to prevent malfunctions if one selects an NV memory area that is not initialized and may contain wrong data, which may have a different meaning to the newer firmware.

Press Setup button #1 <USER> and #6 <no label>. It will take about 5s. This should only be allowed for experienced operators or the administrator.

Lock Desktop-Unit pane Setup buttons can be locked individually as well as User Buttons and/or Bus Buttons.

Select Channel for Preset Shortcuts pane You can predefine a Channel Strip where to load a preset by means of a Preset short cut. Press <DSP> and one of the <USERx> or <BUSx> buttons.

Button Behavior pane One may now decide about the behavior of the MIX4 buttons : The selection is between : toggle pressing the button once will turn the function on Pressing the button a second time will turn the function off push The function is activated as long as the button is depressed both the buttons operate in both modes where pushing the button longer than a second will force it to perform the push function

Controlling the MIX4 with SDI Interface Installed

Within the SDI (Serial Digital Interface) data stream 4 audio-groups (GR0 to GR3) can be embedded. Each group carries 4 single channels. Normally these channels are interleaved by pairs to minimize delay times between them. When audio channels have their origin from an AES/EBU signal one can keep this correlation also within the SDI embedded audio domain.

The SDI interface of the MIX4 can handle 2 of these groups at a time because it corresponds with the 4 x 2-channel concept of the interface boards. The drawing below shows the block diagram of that interface board and a routing example that assumes GR0 and GR1 (which are the most common groups for broadcasters) are selected for use with the MIX4 :

Block diagram of MIX4 SDI interface Routing example for Groups GR0 and GR1

The SDI data is converted from serial into it’s 10bit parallel format. Afterwards the ancillary data part (see SMPTE 291M for details) of the 10bit words is taken apart while video data will pass this process untouched. In a next step the pre selected 2 groups are taken and converted into a 4 x 2ch serial audio data stream that will be sent to the MIX4s internal router for source selection. The other 2 groups will be interrupted (see above example).

From the 4 output busses of the MIX4, the 4 x stereo signals are sent back to the interface. For embedding on the SDI interface board the output signals from the busses m ay be combined with the input signals to allow for transparent mode (e.g. for dolby-E pass through).

From the de-embedding side we have access to the 2 pre-selected groups. The decision is made by Setup software (see S

ource section).

For the embedding side one can decide if one wants to embed the MIX4 stereo buses o r pairs from the SDI input channels. This is under direct access from the desktop remote unit.

Both interface slots can have a SDI option board installed. This allows for processing of two independent video signals (e.g. a VTR player and a workstation recorder).

SDI groups to embedder

page 37

Jünger Audio-Studiotechnik GmbH

The SetUp software of the MIX4 shows on the H

ardware- and Sources pages, if a SDI interface is installed :

With actual firmware the MIX4 can make use of two of these audio groups at a time. This must be set on the

ources page : This setting applies to the de-embedder as well as to the embedder.

Because the MIX4 is a stereo mixing desk the mix busses are stereo.

The sources are treated also as stereo by default. But one can force by SetUp-Software option „Force 2Ch“ that sources are always treated in 2-channel mode.

If „Force 2Ch“ is not activated the switch over : STEREO < > 2Ch is possible via the 3push mode from the desk top remote. (See below :)

For audio sources from a SDI interface board applies : Pairs from a SDI group are treated as stereo signals. But if „Force 2Ch“ is selected, twin SDI channels will be treated as mono signals all the time.

The assignment of the stereo busses of the MIX4 to the twin SDI channels must be controlled from the desk top remote. Beside the assignment of stereo busses to the twin channels while embedding, one can also arrange transparent pass through of the SDI embedded audio input signals. For example, it is possible to move channels 1 and 2 (CH12) of group 0 (GR0) into the channels 3 and 4 (CH34) of group 0 and in lieu thereof embed one Bus of the MIX4 (e.g. BUS1) into channels 1 and 2 (CH12) of group 0 (GR0).

The MIX4 can operate two SDI interface boards. To set up the embedder1 (SDI interface in slot1), you must press the <BUS> button. To set up the embedder2 (SDI interface installed in slot2), you must press <BUS> twice.

page 38

Jünger Audio-Studiotechnik GmbH

If one presses the <BUS> button, one sees the MIX4 menu display to control the assignment of channels to the embedder1 (installed in interface1).

In the upper line the targets (to the embedder) are displayed while the sources are displayed in the bottom line (one of the busses or transparent channels from the de-embedder).

For this example groups 0 and 1 have been pre selected by the SetUp software : GR1 GR0

The actual assignment is done by turning the related Channel Rotary Knob. In this example the following selection is possible :

BUS1 BUS2 BUS3 BUS4 GR0 CH12 GR0 CH34 GR1 CH11 GR1 CH34

On the input side one can select the desired channels from the SDI signal for each MIX4 Cha nnel Strip independent from the settings for the embedder: For this one must press the <SRCE> button first and the Channel Button for which one will change the source afterwards :

Thereby one can read in the upper display how the signals of that particular source will be treated. By pressing the channel rotary encoder the mode will be altered between :

STEREO > LEFT > RIGHT ( > STEREO)

With this one selects the left or right channel of the audio twin from the SDI by 3push mode.

Within the bottom line the labels which have been assigned for both channels by the Setup software will appear one after the other.

page 39

Jünger Audio-Studiotechnik GmbH

The pictures below shows the display for 3push mode :

The first push on the Channel Rotary Knob will select the left channel : LEFT of the source GR0 CH34, thus channel 3 / group 0.

The second push on the Channel Rotary Knob will select the right channel :

RIGHT

of the source GR0 CH34, thus channel 4 / group 0.

The third push on the Channel Rotary Knob selects both channels again :

STEREO

of the source GR0 CH34, thus the channels 3,4 / group 0.

After leaving the <SRCE> selection mode, underscores in the display will show the status of the sources selected for the respective channel strip :

GR0 CH1 (the label has been assigned by set up software), the left channel of the pair CH12, is selected for Channel Strip A

GR0 CH2, the right channel of the pair CH12, is selected for Channel Strip B.

GR0 CH34 are in stereo mode and selected for Channel Strip C - no underscore.

Junger Audio DDE client for VADIS II

For efficient cooperation of the MIX4 and the VADIS II System by KlotzDigital a second network adaptor binded to TCP/IP protocol at the control computer for the VADIS system must be installed. Communication with the VADIS system is taken over by the DDE client by Junger Audio, which repre sents itself as a server to the MIX4.

Because of different naming conventions and source management within both systems the DDE client prepares all data in a suitable manner so that the MIX4 gets all necessary information in its name convention (8 characters for a GroupName and 8 characters for a SourceName). At the same time the number of selectable sources for the MIX4 is limited by the set up functions of the DDE interface to a maximum of 16 and the differentiation between 2 channel and stereo sources will be made here also. Inside the MIX4 sources are always treated as 2ch ones, Therefore a mono source is proces sed as a ”double mono” signal. To improve clearness we suggest you label the VADIS outputs, which are reserved for connection to a MIX4, in a meaningful way. Here an example configuration to explain the possible settings :

Because this program automatically writes an actual initialisation file on exit no further file operations are necessary and the menu F

ile only offers the option Exit. in the Settings menu the selection of VADIS in and outputs can be locked : Change In’s for MIX4 / Change Out’s to MIX4

VADIS inputs and outputs can be filled into the In’s for MIX4

and Out’s to MIX4 fields by drag&drop operation

the xxx sign serves for deleting of entries by

dragging it into the relevant In’s and Out’s fields

status display for all MIX4s connected

including an edit field for entering a name

to distinguish between multiple MIX4s

Pull down menu to select a MIX4 input to which a

VADIS Output is physically connected to

After starting the DDE client all available inputs and outputs of the VADIS systems are gathered and entered into one of the two windows respectively.

page 41

Jünger Audio-Studiotechnik GmbH

In the In’s for MIX4 field the selection of possible VADIS sources for each connected MIX4 is limited to a maximum of 16. The selection is performed by drag&drop from the Vadis Inputs windows into one of the two windows in the bottom fields of the respective input blocks IN1 to IN16. Each of these input blocks has two windows to input a GroupName and a SourceName that are displayed in the MIX4 channel display if that input is selected for routing. Finally, there is a check box to define stereo (checked) or 2 channel mode (empty). The Out’s to MIX4 is simply labelled by using little pull down windows. These are the physical inputs of MIX4 where the trunk lines (tie lines) from VADIS are connected. They are brought into relation to VADIS outputs by dragging & dropping them into the respective field (therefore our recommendation to negotiate meaningful names in VADIS set up - MCCU program). 3 little x’s in both fields serve to delete entries by dragging & dropping them into the relevant area.

Note : The pull down windows for labelling the outputs can only be closed by explicit selection of an item (no <ESC>, no clicking to a different area). This is sometimes boring if one clicks such a window by accident -

.... Unfortunately this is handled by the OS in an uncomfortable way and out of our control.

Finally there is a status display for connected MIX4s. It is important to know that each MIX4 which operates with a VADIS system must have its own name and an unique ID number. The MIX4 name and it’s ID number must be set by the SetUp software (use Main page for Name and Router page for Port/ID number). The ID number corresponds with the location of the status field inside the window at the right hand. The first field represents the ID #1 and the one at the bottom the ID #8.

Only if the settings of ID number and MIX4 name are correct at both ends (VADIS DDE client and connected MIX4) there will be a valid connection via TCP/IP. On the Router page you must read a MIX4 ID number. If not you must set the port number to 55555. After reading back from Device that input field will change to a pull down menu for selecting a valid MIX4 ID from 1 – 8.

It is obvious that it goes hand in hand with a correct IP number and subnet mask for the MIX4 itself as well as the declaration of the VADIS IP number for the MIX4 (see Router Page in SETUp software).

Installation of the system : KlotzDigital has made some changes to the DDE integration to make third party DDE clients work. Therefore the VADIS system needs a version that is compatible to Junger Audio DDE client. Pls. check with KlotzDigital which files you need to update your current VADIS system.

First install the network adapter and bind it to TCP/IP (pls. refer to KlotzDigital DDE manual) and do the correct settings of IP number and subnet mask for your actual network. (You will need to tell each MIX4 working with VADIS these numbers later on by using the SetUp software.)

On the VADIS PC make a directory e.g. C:\program\Junger and copy the MX4KLOTZ.exe to it. We assume that the VADIS system is running before starting Junger DDE client !

Because the DDE client reads VADIS information on start up. Otherwise starting Junger DDE client will show an empty windows for the inputs and outputs.

Now you can do all settings for Group and Input names, define the tie line of the MIX4 where the router destination is connected to and drag and drop the relevant VADIS names into the fields. Finally you need to input the MIX4 names in the pull down fields of the staus display on the right hand.

On closing the DDE-Client it will write an INI file “Mx4Klotz.ini” that contains all settings one has done previously. This is a simple text file you can also manually edit if it is more convenient for you instead of using the editing tools from the DDE-Client window.

Set up the MIX4 to remote control Madozzi router functions

The procedure to prepare a MIX4 controlling the Mandozzi router is quite simple. Pls. ensure that the MIX4 and the PC, where the Setup software is running on, are connected to the LAN where the Firewall PC resides. In case of unknown IP configuration you must have serial connection with the MIX4.

1. First you must go to the H

ardware page and perform a “from Device” to load the current settings into

the Setup software.

2. You must assign a unique IP address and subnet mask to the MIX4 as well as a gateway address if

necessary (pls. contact the system administrator for IP addresses). Such IP configuration will only be valid after a power cycle of the MIX4.

2 The “Name:” field is optional and can be left blank

3.1 On the R

outer page you must enter the IP address of the Mandozzi Firewall PC.

3.2 If the application port number is different from 50000 that number will appear below

Configuration > IP-Address. You must correct it to 50000 for proper operation.

page 43

Jünger Audio-Studiotechnik GmbH

4. Send the Setup “to Device” and power cycle the MIX4 if its IP configuration has changed.

5. Press the “Configuration” soft button on the R

outer page. This will load the actual router configuration into the Setup software. Depending on the size of the router, this process may take a few minutes!

When done a page similar to the one below will appear on the PC screen :

6. Here you may pre select 16 groups of 8 sources each from the total of thousands of router sources. The group name can be edited in the “Groupname:” field below the line of group labels (see above). You may disable a group completely if there is no need for as much as 16 groups for the current application of the MIX4. This also applies to the sources within a group. If there is no need for as much as 8 sources per group you should disable the unused ones. The reason for this option is to prevent the operator from “dialing“ through a number of sources he does not need to do his job.

7.1 Each source for the MIX4 can be selected by a pull down box that opens, if one clicks the triangle soft button on the left side of the configuration field :

page 44

Jünger Audio-Studiotechnik GmbH

7.2 You can scroll through that list. The selection is made by clicking on a list entry.

8. The list entries are organized in two categories.

8.1 Stereo sources have different source coding for the left and right channel

8.2 Mono sources have the same source coding for the left and the right channel

9. If you have set up the sources for the MIX4 you must setup the input configuration. The MIX4 is connected with the router by tie lines. You must tell the MIX4 the output of the Router to which the relevant input is connected.

This is the 2

important information for the MIX4 to set the correct cross points.

10.1 Go to the S

ources Page and check the Router check box for the input where a tie line from the router

is connected to. A pop up will appear on top of the page. Here you must click the triangular soft button :

10.2 Scroll through the list to select the tie line that is physically connected with that MIX4 input :

Important Note! As already mentioned in the <Monitor> Setup chapter : Both the “Router” and the “Disabled” check boxes must be ‘checked’ for a monitor tie line. This will automatically prevent that tie line from being assigned to a Channel Strip! And it will be exclusively used for monitoring purposes :

The example above assumes 3 tie lines names RTL (2 for mixing and one for monitoring purposes) connected to the Interface 1 option board (AES/EBU I/Os in this case), where input #3 is not in use (and therefore disabled).

10.3 Finally you must send the source set up “to Device”.

Jünger Audio-Studiotechnik GmbH

Set up the MIX4 to remote control DHD – RM 4200 router functions

The procedure to prepare a MIX4 for DHD router remote control is quite simple. Pls. ensure that the MIX4 and the PC, where the Setup software is executed, are connected to the LAN where the DHD router and the PC that holds the CSV type configuration file reside. Make sure that the MIX4 and it’s Setup computer have serial connection.

1. First you must go to the H

ardware page and perform a “from Device” to load the current settings into

the Setup software.

2. You must assign a unique IP number from that LAN to the MIX4 (pls. contact the system administrator).

3 Next enter the sub net mask from that LAN

4. The “Name:” field is optional and can be left blank for DHD login.

5. On the R

outer page you must enter the IP number of the DHD Device.

page 46

Jünger Audio-Studiotechnik GmbH

5.1 If the application port number is different from 2008 that number will appear below the IP number. You must correct it to 2008 for proper operation.

6. Send the Setup “to Device”.

7. Press the “Configuration” soft button on the R

outer page. This will open a file dialog :

From here one must choose the CSV (comma separated) file that contains the actual Device

configuration. Such file you must export by the DHD “Toolbox”. There you must open the File menu and select “Export DSP Frame I/O as CSV ….”.

page 47

Jünger Audio-Studiotechnik GmbH

If you have selected a *.csv file a similar screen like below will appear on the R

outer page :

8. Here you can pre select 16 groups of 8 sources each from the total of hundreds of router sources. The group name can be edited in the “Groupname:” field below the line of group labels (see above). One may disable a group completely if there is no need for as much as 16 groups for the current

application of the MIX4. This also applies for the sources within a group. If there is no need for as much as 8 sources per group one can disable the unused ones.

The reason for this option is to save the operator from “dialing“ through a number of sources he does

not need to do his job.

page 48

Jünger Audio-Studiotechnik GmbH

9. Each source for the MIX4 can be selected by a pull down box that opens, if one clicks the triangle soft button in the far left column :

9.1 One can scroll through that list. The selection is made by clicking on a list entry.

9.2 The list entries are organized in two categories.

Stereo sources - different source coding for the left and right channel Mono sources - same source coding for the left and the right channel

9.3 If you have filled in all groups of sources you need for that particular MIX4 you must configure the inputs where the tie line(s) from the DHD frame are connected to.

9.4 Pls. go to S ”to Device” (H

ources and make the appropriate settings. If already done don’t forget to send the Setup

ardware page).

page 49

Jünger Audio-Studiotechnik GmbH

10. On the S

ources page click on the Router check box of the respective input :

The following screen will pop up on the S

10.1 Press the triangle soft button :

ources page :

page 50

Jünger Audio-Studiotechnik GmbH

10.2 The selection screen below shows up :

10.3 Here one must select the DHD output that is connected with that MIX4 input. It is a good practice to name these tie lines in a way one could easy choose them from this list. The naming is done by aid of the DHD Toolbox (go to the item “DSP frame I/O”).

Also we would recommend to set up each tie line as a stereo signal (see MIX4_MON label ab ove). Stereo Lines can be detected by the leading hex number 2 (0x2yyy).

Important Note! As already mentioned in the <Monitor> Setup chapter : Both the “Router” and the “Disabled” check boxes must be ‘checked’ in Setup software for monitor only purpose. This will automatically prevent that tie line from being assigned to a Channel Strip.

10.4 Finally you must send the source set up “to Device”.

Operator / Preset Manager & Backup / Restore Tool (OPBR)

The tool “MIX4Backup.exe” is meant to manage operator profiles and preset data as well as to back up and restore a MIX4 device.

After launching the tool you must select between the main functions : Manage / Backup / Restore / Copy :

“Mode” decides between operator profiles, presets und device processing

“Interface” defines the way how to communicate

“Input/Output” defines the direction and kind of data

transfer

Both windows to the left will hold data of devices or files. The content depends on the “Mode”. Within the “Preview” window you can see the names of operator profiles or presets from a device or from a file. The files that store operator or preset data are organized in the same way as such data are stored within a device, i.e. you can put data specific to a place within a file or a device. To change the position of such data within a file or device, you can move the name of data sets in the right window before you transfer or store it to a target. You can preview the existing names from a target in the left window.

The soft buttons serve to select sets of data, to mark items, clear the list, edit (presets only), load and store data. Some of these buttons are labelled in a context sensitive way.

Within the “Workspace”, positions of data sets can be moved up and down ward to place it to unused positions or to overwrite existing data when you store a file or you send the data to a device. This offers grate flexibility if for example you will generate sets of operator profiles or preset data which may be loaded on demand later on. This allows for manage much more than 10 operators or different sets of presets for broadcast stations because it can ease the disposition of people to prepare edit su ites for different shifts.

When you press <Receive> you will get a pop up. There you see the IP address of the device you have “talked” to last time. If you run the tool fro the first time, you must enter an IP address here.

When you push the list button you see a list of all devices you have been previously connected with from this computer.

The details of connections are stored by the registry of the MS Windows™ operating system. If you have lots of connections in use and you would like to transfer such information to a different PC, you must export the registry key which you will find here :

HKEY_LOCAL_MACHINE\SOFTWARE\Juenger Audio\SDM4Base\

The example below assumes you are about to mange operator profiles :

After you have selected “Operator Profiles” and have pressed <Receive> all operator names have been read from the device. The list entries 2 - 5 have been checked. By pressing <Import> the data sets have been loaded to the “Workspace”. Over there they are checked again. By pressing <Save As> you can now either store it to a new file or you can open an existing one and have a look which positions within the file are empty or due to overwrite. But you can also read a list of operator profiles from a different device to have a look if there is “room”.

If necessary you can move sets of data to different positions in the “Workspace”, to store it into the left hand opened file by pressing <Save> or to move it by pressing <Send> into the device displayed left side. Therefore you must move the label via drag and drop to the desired position of the list. The list entry possibly existing will automatically be moved to the next position. To store or send such list entries you must mark the appropriate check boxes.

In the left window the list entry „Eckhard“ is high lighted. Therefore the label of the bottom left soft button changes to <Load Eckhard>. If you push it, this operator will be remotely logged in for the selected device.

The next example shows a list of presets loaded from a device. The entries 1, 3, 4, 5 und 9 have been marked and afterwards moved by <Import> into the “Workspace” :

In the “Workspace” the entry number 3 “SM69” is high lighted. The label of the soft button shows now <Edit SM69>. If you press it, the edit window for a preset pops up. The parameters are arra nged in the same way as they are in a device. Drag label, radio buttons and a pull down menu are used to enter parameters :

On the top there is an edit window to enter preset names To the left you can turn on the DSP function, change signal

You must click into a drag label and hold the mouse button down. Now you can change para meters by moving the mouse pointer horizontal. If you click close to the left and right edges inside a drag label, the value jumps to the maximum / minimum of the existing range.

In the edit field you can also enter a preset name. It is limited to 8 characters. After closing the edit window, the actual preset is checked and may now be sent back to the device or to another device. But you can also store it into a file by pressing <Save As> or you can edit other presets before moving a bunch of it to a desired target.

If you open an existing file by <Open> you will see the already stored presets. Now you can arrange the presets existing in the “Workspace” in a way that they are placed at unused positions or at positions where they will overwrite existing data. Finally you must check the presets which you will store or transfer. If you would like to store all active entries you may use the <Select All> button. <Save As> will store to a file, <Send> will open the pop up to select an existing device if TCP/IP was selected. If serial is selected the data transfer will begin without further notification.

In the example above the entry named „Telefon“ is checked. The bottom right soft button is now labelled <Load Telefon>. If you press it, a dialog window will pop up :

Here you can select one or more channel strips where the preset will be loaded to.

Operation of a Telephone Hybrid or ISDN Codec with the MIX4

There is a combined function for using the MIX4 with a Telephone Hybrid or an ISDN Codec. This mode is within the Setup software by choosing the HYBRID function. The drawing below shows a

The first step is to select a Mix4 G

PI for signaling an incoming call.

The next step is to select a MIX4 Ta

lly output that signal the hybrid to accept the incoming call.

On the D

esktop-Unit page of the Setup software, a User Button function must be selected to permit direct

talking to the hybrid. In this case the local talkback source is used. On the M

ain page, the bus to be used to feed the hybrid will be selected by selecting the HYBRID function

for that bus. Finally the HYBRID function must be activated on the S

ources page for the Channel Strip button where

HYBRID has been selected as the input. When HYBRID is selected for the first time as a source for a Channel Strip, you need to decid e via

<SOURCE> selection from which channel (L or R) the sign al is taken and how the <BUS> assignment will be so as to insure that this Strip is not routed to the bus that feeds the hybrid! Unpleasant feedback could otherwise result!

page 57

Jünger Audio-Studiotechnik GmbH

An incoming call (signaled by the GPI) will be shown by that Strip’s channel button blinking dark yellow. Pressing that button will take that call by closing the Tally and will activate the PFL function so one can listen

to the caller.

The Channel Button will light bright yellow. The User Button will be blinking green and can be pressed to talkback to the caller.

This function is often called “pre talk” When the Strip’s fader is then opened, the PFL function will be switched off, the previous monitor source

(normally the bus monitoring of the transmission or recording line) will be selected, and the Channel Button starts blinking bight yellow to indicate that the call is still active and now on air.

The host can now talk live to the caller through his on air microphone and the opened fader of the hybrid.

After closing the fader, the hybrid caller is off air.

The channel button is still blinking bright yellow. One can recall the PFL function by pressing the channel button again to perform a “post talk” The channel button will light bright yellow again

The User Button will be blinking green and can be pressed to talkback to the caller

If the channel button is now pressed again the GPO Tally signal will be turned off and the hybrid will terminate the call.

MIX 4 Dynamics – The Junger Multiloop™

The Junger Multi-Loop™ Dynamics principle sets a new standard for digital signal processing. The Multi-Loop™ principle combines the advantages of multi-band processing with the advantages of bro ad

band dynamic processing. But unlike multi-band processing, Multi-Loop™ preserves the frequency

response of the signal.

The multiple control loops process audio simultaneously

. A brief delay lets the digital control loops “look

ahead” so they know in advance what is happening in the audio. This lets them catch peaks completely, with no overshoot, breathing, etc.

Principals of Multi-Loop™ Compressors

The Junger Multi-Loop™ also allows adaptive controlling of the parameters of the control loops. The Multi-Loop™ DSP module analyses the structure of the input signal and adjusts the attack and relea se times automatically to match. This allows for simultaneously relatively long attack times for calm program material and very short attack times for transients.

To optimize the Multi-Loop™ for various program or signal types, it is possible to set processing parameters. Such parameters represent a certain range of values of time constants which will be used as a basic set for Adaptive Controlling. Thus they define a passage wherein the adaptive algorithms perform best and ideally adapt themselves to the program material. The adaptive algorithms guarantee the best reaction to transient signals at all times.

The value PROGRAM sets the time constants as follows :

PROGRAM processing time suitable for

----------------------------------------------------------------------------------------1 5 ms to 0.5 sec 2 10 ms to 0.8 sec 3 15 ms to 1.2 sec SPEECH 4 30 ms to 2.5 sec POP 5 50 ms to 3.5 sec 6 70 ms to 5.0 sec UNIVERSAL 7 100 ms to 6.0 sec 8 150 ms to 8.0 sec CLASSIC 9 250 ms to 10.0 sec

The control ranges and the algorithms themselves have been determined so far by countless listening sessions with audio engineers, musicians, producers so they cover all genres.

Not sure what to use? Want a general setting that will work well for all cases? Use Universal! The other settings, noted for Speech, Pop, and Classic will give ideal settings for those signal types. But UNIVERSAL will cover all of these very well – better than any other unit you will encounter.

The limiter with transients always utilizes an attack time of 0 (zero). The release time has more influence on the increase of loudness than all other parameters.

The Mix4’s Multi-Loop™ Compressor acts rather differently than traditional compressors regarding gain. Compression is defined as the reduction of the dynamic range of the input signal to match the dynamic

range of the storage system, transmission system, and/or the listening environment. Typical approaches to this task often result in audible artifacts and lack luster performance. The Junger approach takes an atypical approach that avoids these difficulties.

input

[dBFS]-10-20-30-40-50-60

In the Junger system, compression of the program signal takes place over the entire input level range, not just the upper end above a certain threshold level.

Compression is partly achieved by increasing the level of low level signals. The lower the input signal level, the higher the additional gain applied to that input signal by the compressor. As the level of the input signal rises, the amount of gain applied is reduced. Please see the figure to the right.

[dBFS]-10-20-30-40-50-60

The gain of the compressor (called ‘range’) can be limited from 1 dB to 15 dB to prevent unacceptable increase in backgrounds during signal pauses (e.g. ambience).

To help eliminate unwanted very low level noise (air-conditioning, hum, and noise), a Junger Expander can be used. Below an adjustable threshold level, the

expander will attenuate the level of the incoming signal. As the incoming signal drops so low that it is ‘in the noise‘ the Expander reduces the signal level further to ‘hide‘ the noise.

output

The Range parameter sets the maximum attenuation applied when the incoming signal level is within 6 dB below the Threshold level.

The limiter of the MIX4 has an adjustable threshold. It defines the trigger point of the limitation and normally is set to 0 dBFS. If this value is lowered, the rotation point of the compression response curve will be moved in parallel..

For operating it is very important to show these relations quite plainly in order to make optimal use of the few necessary settings. Therefore, it makes no sense to increase the system gain when the limiter is already operating. It will not be audible over a wide range of GAIN but small signal level will be increased unnecessarily.

page 60

Jünger Audio-Studiotechnik GmbH

Beside overload free and frequency independent dynamic processing the MIX4 utilizes new filter principle s. Dynamic filters only take effect up to a certain defined threshold :

Static Filter (Range = -10dB) Dynamic Filter (DE-ESSER)

This the DE-ESSER makes use of. Here the adaptive controlling adjusts the Threshold dynamically to the processed signal. Therewith the setting of the DE-ESSER needs only two values: RANGE (the penetration of the dynamic filter to the signal) and mid frequency from 1kHz to 14kHz. In addition to this there are two optimized values called male and female.

Level diagram of MIX4

In the Digital World, maximum level is defined as 0dB Full Scale (0 dBFS). Of course, this does not mean that program levels from one source to another will be the same!

Digital sound storage media are controlled for peak levels up to

A defined operating level to which Operator’s can rely on as standard is essential.

The MIX4 may be adapted to any individual situation to meet either different media requirements or for the connection to analog transmission lines. The MIX4 operates at the analog inputs up to a level of +22 dBu. This compares to a digital level of 0 dBFS after A/D conversion. E.g. if an analog level of +6 dBu shall cause a digital level of -9 dBFS, a (digital) gain of 7 dB is necessary. In addition, the GAIN settings within the channel strip are provided to achieve a reasonable adjustment range for the faders for a given operating level.

page 62

Jünger Audio-Studiotechnik GmbH

At the output you can set the maximum analogue level based on 0dBFS. For our example one must set the output to +15dBu. I.e. at 0 position of the channel fader and with a channel gain of 0 dB the operating level at the output will be +6dBu again (incl. 9 dB headroom).

As noted early on above, the microphone inputs can also be used as analogue line inputs.

For microphones with small output levels the important thing is to achieve an optimized noise behavior. For line level analog inputs, maximum input level is more critical. Three settings provide for these cases:

In setting MIC LOW (see Setup software) the equivalent noise level (termination 200Ohm) is

-126dBu (RMS) with a maximum inputs level of -26dBu. In setting MIC HIGH (see Setup software) the equivalent noise level (termination 200Ohm) is

-110dBu (RMS) with a maximum input level of +10dBu. In setting LINE, the clipping point of the input is +26dBu and the overall dynamic range is

110dB. The setting HIGH also provides a compromise for microphones with higher output levels - this will work well with mics with line level outputs.

By combination of a compressor within the channel strip and limiters on the output busses, you can control signal dynamics very well. While both sections operate wideband there is no negative effect on the sound as long as you operate within a moderate range of compression and limiter range values.
