WEEE & RoHS Directives - Sonifex Statement

The Waste Electrical and Electronic Equipment (WEEE) Directive was agreed on 13 February 2003, along with the related Directive 2002/95/EC on Restrictions of the use of certain Hazardous Substances in electrical and electronic equipment (RoHS).

The Waste Electrical and Electronic Equipment Directive (WEEE) aims to minimise the impacts of electrical and electronic equipment on the environment during their life times and when they become waste. It applies to a huge spectrum of products. It encourages and sets criteria for the collection, treatment, recycling and recovery of waste electrical and electronic equipment. All products manufactured by Sonifex Ltd have the WEEE directive label placed on the case. It gives a contact for individuals who are unsure about the correct procedure when the product has reached its “end of use”.

Sonifex Ltd will be happy to give you information about local organisations that can reprocess the products, or alternatively all products that have reached “end of use” can be returned to Sonifex and will be reprocessed correctly free of charge.

Sonifex Ltd has phased out the use of certain hazardous substances identied in the European Union’s Restriction of Hazardous Substances (RoHS) directive. The RoHS directive limits the use of certain hazardous substances currently used in EEE manufacture, including lead, mercury, cadmium, hexavalent chromium, and halide-containing compounds PBB (polybrominated biphenyl) and PBDE (polybrominated diphenyl ether). Elimination of these substances will result in more environmentally friendly recycling of electronic equipment. For the products which Sonifex manufacture, the main area where products were aected was in the use of lead for manufacturing and assembling electronics circuit boards.

Sonifex Ltd practices lead-free (LF) manufacturing processes. LF solder is used on the surface-mount PCB manufacturing processes and for hand soldering. The printed circuit boards (PCBs) used are either gold plated, or immersion tin plated, both of which use no lead. Historically the PCBs were hot air solder levelled (HASL) PCBs which used tin/lead based solder.

The manufacturing processes include the assembly of purchased components from various sources. Product is oered as RoHS compliant, or LF, only after sucient evidence is received from the component manufacturers that their components are RoHS compliant. Sonifex Ltd relies solely on the distributor, or manufacturer, of the components for identication of RoHS compliance. Thus whilst every eort is made to ensure compliance, Sonifex Ltd makes no warranty, or certication, or declaration of compliance concerning said components.

Sonifex Ltd denes “Lead Free” as pertaining to any product, which has been manufactured by Sonifex Ltd using components which have been declared by the manufacturers as “Lead Free”. All statements by Sonifex Ltd of RoHS compliance are based on component manufacturer documentation.

INTRODUCTION

Installation Notes

Atmosphere

The S1 mixer should be installed in an area which is not subject to excessive heat or cold. Also, you should avoid installing it in atmospheric conditions which are dusty, smoky, or dirty, or where there is moisture or vibration. Do not use any liquids to clean the fascia of the mixer: a soft dry brush is ideal. Use a clean cloth moistened with water or ethyl alcohol to clean the trim and scribble pads. Other solvents may cause damage to paint or plastic parts.

Electromagnetic Radiation

Avoid using the S1 mixer close to strong sources of electromagnetic radiation such as, video monitors or high power electric cabling. This may cause degradation of the audio quality due to induced voltages in connecting leads and chassis. In all cases the S1 mixer should be installed and serviced by qualied personnel.

Dimensions and Cut-Out Sizes

The cut-out size is for reference only and should be checked with your mixer.

Channels 1 and 2 Mic / Line Inputs

The Mic/Line Input channel is a mono input with a button switch to select either Mic or Mono Line. Channel 1 is used for the presenter’s mic and is the source for talkback. The Talkback source can be set to come from either the Mic or the Line source irrespective of the channel input selection.

Channels 3 and 4 - Mic / Mono Line / Stereo Line Inputs

The Mic/Mono Line/Stereo line Input channel is a stereo input channel with a button switch to select either Mic, Mono Line or Stereo Line. The stereo line is fed through a jack connector which is found in the centre of the XLR line connectors.

Channel 5 - Mic / Telco Input

The telco channel is used to interface the S1 with a telephone hybrid unit. The hybrid unit is connected through an XLR with a Microphone channel provided as an alternative. The telco channel connector group also contains a cleanfeed output via XLR to return to the Hybrid.

Channel 6 – Stereo Line / Stereo Cleanfeed Input

The Stereo Cleanfeed channel has one balanced stereo input and a balanced stereo cleanfeed input, on XLR connectors. The channel is intended for use where a remote stereo source, such as another studio connected via ISDN, requires a stereo cleanfeed return. The cleanfeed is generated by a separate stereo cleanfeed bus which follows the PGM output routing matrix.

Channel 7 and 8 – Stereo Line / RCA Inputs

Channels 7 & 8 have one balanced stereo input and an unbalanced RCA stereo input. Channel 7 also has DROP IN connector which allows for an input from a a 3.5mm jack connector.

Channel 9 and 10 - Stereo Line / Digital Inputs

The Digital Stereo Input channel has one standard stereo XLR Analogue Input channel & one 24-bit 192kHz digital inputs with a button switch to select between them. The digital input is auto sensing & can be connected via either SPDIF or Toslink. The digital signals are converted to analogue and from this point the channel functions are the same as the Dual Stereo Line Input channel.

External Inputs

Two external inputs are available to the S1 through a 9 pin D-Type connector located on the rear panel. The external inputs are used for audio which should be heard in the control room but not on air. The pin out for this connector can be found in Appendix B.

Input Selection

Selecting the button changes the channel input connection between Input 1 (Mic) and Input 2 (Line). The button is illuminated in red to indicate when input 2 is selected. When the channel is routed, so that the ON button glows green, the input selection cannot be changed.

Channels 3 and 4 have three selectable inputs; Mic, XLR Mono Line, ¼” unbalanced stereo line. The input selection button will glow red when Mono Line is selected and Orange to indicate the stereo input is selected. The button can be congured using SCi so that the button is forced to a particular input or alternatively the selection of either the Line input or the Stereo Line input can be inhibited so that the button has only two options as two line sources cannot be simultaneously connected.

DROP-IN Jack

On Channel 7 only, there is a 3.5mm insert jack allowing the direct connection of mp3 players or other portable consumer equipment. When the INSERT jack is in use, it overrides the Input Selection Button.

AUX Controls

Each channel is sent to both auxiliary buses at all times. The AUX controls allow adjustment of the level of each channel on the bus to achieve a perfect mix. The control changes the level between fully attenuated and unity so to remove a mix from a particular auxiliary bus, fully attenuate that particular channel.

Equalisation Controls

In some situations you made need to change the equalisation of your audio. The HF and LF controls are used to adjust the equalisation of the signal. The HF control boosts and cuts the signal by ±7dB at 6.5kHz. The LF control boosts and cuts the signal by ±7dB at 100Hz. The fundamental frequency of human voice generally sits between 100 and 150 Hz. Try lowering the LF control on microphone channels to get rid of any unnecessary low frequency audio while slightly boosting the HF to add clarity.

USER GUIDE

TRIM Control

The Trim control is used to tweak the level of the channel on the PGM output. It provides an additional ±12dB of gain to ne tune the input signal level. It is a good idea to set up all your audio channels so that they are all at the same reference level when the fader is fully up, meaning the mix levels are determined solely by the position of the faders. This is where to use the trim pots, for level adjustment which remains constant through the mix.

PAN Control

The Pan control is used to pan the mono input signal on channels 1,2 and 5 in the stereo image. Fully anti-clockwise pans the signal to the left and increases the signal by 3dB (right channel reduces by 70dB); full clockwise pans the signal to the right and increases the signal by 3dB (left channel reduces by 70dB).

Balance Control

The balance control is used to alter the stereo image of a stereo input source on channels 3, 4, 6, 7, 8, 9 and 10. Turning the potentiometer fully anti-clockwise shifts the signal to the left and increases the signal by 6dB (right channel reduces by 6dB); fully clockwise shifts the signal to the right and increases the signal by 6dB (left channel reduces by 6dB).

CUE/PFL Selection

Selecting the CUE/PFL button routes the pre-fader input signal to the monitoring system where the signal can be heard via headphones and/or loudspeakers. The level may be checked on meters and adjusted via the TRIM control and panned via the PAN control. The button is illuminated in green when CUE/PFL is active. There is a conguration option to cancel the CUE/PFL selection when the fader is raised. This button works with both a momentary and latched operation. If held down, the selection is cancelled when released, otherwise the button is alternate action.

CUE/PFL & T/B Selection

On channels 5 and 6 the CUE/PFL and T/B button operates similarly to a standard CUE/PFL button except the talkback source is also routed to the respective cleanfeed output when the channel input is set to Input 2 (5. Telco or 6. Stereo Cleanfeed).

USER GUIDE

An additional option that is congurable using SCi allows the presenter to CUE/PFL the Telco or STCF inputs whilst preventing the talkback source from being routed to the cleanfeed outputs. If Talkback routing on this channel is ‘disabled’, the CUE/PFL & T/B button shall ash green when selected to indicate that talkback is not routed to the cleanfeed bus. Talkback can be routed to the stereo cleanfeed bus by holding the CUE/PFL & T/B button and the button will glow solid. When the button is released, talkback will return to the unrouted state & the button will return to ashing green. CUE/PFL can be deactivated by a momentary press of the button. This option only applies to Input B of this channel.

ON Selection

The ON (called LINE HOLD on channel 5) button works in conjunction with the fader. It is used to control channel remote output logic, channel routing, and timers. The button LEDs show the various operational states of the channel.

Unlit

When unlit the channel is o.

On solid - red

Steady red indicates that the channel is ON and “armed”, ready for the fader to be raised.

On solid - green

Raising the fader changes the illumination to green indicating that the channel is live. With the button unlit the fader may be raised and the channel can be operated simply by selecting ON. The illumination in this case toggles between unlit and green. The channel remotes and timers are triggered when the fader is up and the channel ON button shows green.

Flashing red

On channels 9 and 10 when Input 2 (Digital Input) is selected, the channel ON button will ash red to indicate that the input is not locked to a valid source. The channel cannot be opened if the Digital input is not synchronised to a valid source.

The button can also ash green and ash orange. Please refer to the tally back portion of section 4 (page 34) for more information.

USER GUIDE

Scribble Pad

A scribble pad is provided at the bottom for user labelling of the channel function . This is useful to remind a producer or presenter which channels contain which segments of audio. It is advisable to use a non-permanent pen or pencil in case of changes.

Fader

The 100mm VCA fader provides a method of dynamic in-show level control and operates between fully attenuated in its lowest position and unity gain when fully open. The channel input signal is routed to the PGM output whenever the fader is open, and the ON button is selected. If using the auxiliary bus post fade, the fader position also aects the level of the channel on the auxiliary buses. The faders can be forced up for remote control applications using one of the General Purpose Inputs.

User Guide – Section 2-4 Metering and Monitors

Monitor and headphone sockets

The S1 provides a monitoring system to monitor all output channels or the external inputs. The is useful for setting up the mixer outputs or to simply listen to the mix in a control room. There are four jack outputs in total; two paralleled presenter outputs, one guest output and one monitor output. The source which is heard on the monitoring system is selectable via push button. The buttons are set to interlocking mode by default, which means the button pressed becomes the source, cancelling all others. An alternative mode of operation is mixing mode, which mixes the output sources onto the monitor bus instead. All the buttons can be locked out in either the o or on positions to stop accidental selection. To nd out how to set up these functions further please view section 4 - SCi (page 32). The PGM, AUX1 and AUX2 buttons all illuminate in green. EXT1 and EXT2 both illuminate in red.

Presenter & Guest Headphones Connector

This standard 6.35mm jack socket is used for the control room headphones and the guest headphones. The presenter jack is wired in parallel with the headphone connector on the front panel. Each connector is capable of driving 35 ohm impedance headphones. Please see section 3 – Applications (page 21) if you would like to use more than one set of headphones on a particular output.

Control Room Monitors Connector

This standard 6.35mm jack socket is the output for the control room monitor loudspeakers. A suitable amplier should be used to send this signal to the loudspeakers, or connect active loudspeakers directly to this output.

Monitor and Headphone Controls

Level controls

Each monitor output has it’s own level control which operates ona range of zero to ten. Zero represents fully attenuated and ten represents +6dB in the guest and presenter headphones or unity in the monitor.

Auto CUE/PFL

When the green illuminated AUTO CUE/PFL button is selected, any input channels selected to CUE/ PFL are automatically routed to the appropriate out. The selection of this button can be locked if required.

Split CUE / PFL

The presenter headphones have the additional facility of SPLIT CUE/PFL. When this button is selected, the monitor source will be heard in mono in the left headphone, and CUE/PFL will be heard in mono in the right headphone. The button is illuminated yellow when selected. The selection of this button can be locked if required.

Talkback

When pressed, the Talkback button will route talkback from the talkback microphone to the guest headphones. The talkback signal can be congured to either cut or mix into the headphones.

While the talkback button is pressed, the switch is illuminated RED and the talkback is active. The buttons work with both a momentary and latched operation. If held down, the selection is cancelled when released, otherwise the button is alternate action.

If necessary it is also possible to permanently route the talkback audio to the talkback connector on the back panel irrespective of whether TALKBACK or CUE/PFL & T/B have been pressed. This may be required if an additional talkback routing panel is used to route talkback to multiple locations.

Mute

The red mute LED will illuminate whenever a mic channel, which has been designated to Control Room mute, goes live. This will mute the control room monitors to prevent feedback. Two pairs of contacts on the remote connector of the PGM output channel will close whenever the mute function is active. These can be used to remotely illuminate “Mic Live” lights.

S1 User Handbook

USER GUIDE

Dim / Mute

When a channel with the monitor mute option congured has PFL selected, the control room monitors can be set to either dim or mute. If the fader is then opened, the monitors will mute irrespective of this setting. The red mute LED will still illuminate if the monitors are set to DIM rather than MUTE on PFL.

Meter Controls

Program / Meters Follow Monitors

The PGM / MFM Button selects whether the meters should display PGM only or display the selection that is heard in the presenters headphones. The selection of this button can be locked if required. This button is illuminated RED if MFM is selected.

PPM / VU

The meters can be congured to display either PPM or VU. A red LED is illuminated next to the currently active scale. The meter mode is a conguration option available through SCi

The PPM meters have a 1-7 scale and will be congured such that a 1kHz signal, at 0dBu at the PGM output, will indicate a meter reading of 4. Each mark on the PPM scale indicates a 4dB change in signal level.

The VU meter operates between -20 and +3 Volume units and follows the standard denition for a VU meter. Please see ANSI C16.5-1942, BS 6840 or IEC 60268-17 for more details.

User Guide – Section 2-5 Output Buses

PGM Output

The PGM output provides stereo balanced XLR outputs. The PGM Output is used as the main transmission bus. All channels that are on and faded in are mixed on to this bus.

Fig 2-27: Program/ Meters Follow Monitors

Fig 2-28: PPM / VU

Fig 2-29: PGM Output

S1 User Handbook

USER GUIDE

Cleanfeed Outputs

The Telco cleanfeed is a mono balanced output used to return a mono version of the program bus back to telephone hybrid. All channels except channel 5, input 2 (Telco) are routed to this bus.

The stereo cleanfeed output works in a similar way to the to the telco cleanfeed. Essentially, it is the same as the PGM output without channel 6, input2 routed. This can then be used as a return for an ISDN codec.

Digital Outputs

The S1 has two digital outputs that work at the same time. The rst is AES/EBU which is on a balanced XLR connector. The second is S/PDIF which is found on an unbalanced RCA connector. These both carry the PGM output. The digital output can be synced to either the on-board master clock or either of the designated sync inputs. There are three distinct synchronisation modes:

Master Mode

The digital outputs are locked to the on-board master clock and is therefore constantly operating at the chosen sample rate. No sync signal is used or required. The internal clock can be set to 32, 44.1, 48, 88.2 and 96kHz.

Slave Mode

The digital outputs are locked to one of the three external sync inputs; AES/EBU, S/PDIF or word clock. If the lock is lost, the digital PGM output is disabled until another lock is secured.

Auto Mode

The digital outputs are locked to one of the three external sync inputs but if the sync is lost, the master clock replicates and resumes at the sample rate of the lost signal.

When the digital output of the mixer is set to either slave or auto modes, the desk will automatically synchronise to the rst available input source. The three sync inputs, AES/ EBU, S/PDIF and word clock are all auto sensing.

To learn more about the conguration of synchronisation options, read section 4 – SCi (page 35).

Lock Indicator

The illuminated lock indicator shows that the digital output is locked . If synchronisation is lost then the indicator will ash.

Auxiliary Outputs

The S1 has two auxiliary buses so that alternative outputs from the PGM can be created and used. The mix that is created on these buses is available from a 9 pin d-type connector which is located on the rear panel. For more information on the use of the auxiliary bus, please read section 3 – Making the most of the auxiliary outputs (page 28).

Auxiliary master gain and PRE / POST Selection

Each auxiliary bus has a master gain control. This controls the level of the whole bus between fully attenuated and unity. Each bus also has a global setting of PRE or POST fader. If PRE is selected, each channels audio is routed to the auxiliary bus before it passed through the fader. This means that the fader has no eect. If POST is selected, the audio is routed to the auxiliary bus after it has passed through the fader. This means that the fader now plays a part in the overall level of that channel on the auxiliary bus. This is true whether the channel is turned on or not. If POST is selected, the button will be illuminated red. Both buttons can be locked in either mode. Additionally, by default, a POST auxiliary bus can not be set to PRE until all the faders are down. For more information on how to congure these options, please read section 4 – SCi (page 35).

The Global Talkback Mode provides a method of guests talking to each other when all of their faders are down. The Global Talkback Mode, automatically activates the CUE/ PFL button on the respective channels awell as turning on AUTO CUE/PFL on the Guest Headphones allowing the guests to hear and talk to eachother. The presenter can cancel any of the channel CUE/PFL’s at any time. When a channel fader in the global talkback group goes up, the global talkback mode deactivates and the CUE/PFL and AUTO CUE/PFL buttons return to their original state. To Congure a Global Talkback please refer to the SCi chapter of the handbook.

User Guide – Section 2-3 Making the most of auxiliary outputs

The auxiliary buses provide two alternative outputs to use as desired. This opens up several practical options to the user.

Auxiliary bus to record a session

The user can connect the either auxiliary output to recording equipment and record what is present on the bus. The producer decides what audio is on the bus by setting the volume on each channel to the appropriate level, creating a totally new mix. Using PRE and POST allows the producer to discriminate between recording all audio or just what is faded in at the time. The producer can also decide what output level the mix should have by using the master volume control for the particular AUX channel in use.

Auxiliary bus to record an o air phone call

It is possible to use an auxiliary bus to record a telephone conversation o air, whilst transmitting from the PGM output. Before the conversation, chose an auxiliary bus and turn down all of the individual channel gains. Turn the gain on the presenters channel (typically channel 1) and the telco channel (typically channel 5) to the required levels and set the bus to PRE. When the phone call is received, the presenter can press the CUE/PFL & T/B button and talk to the caller. The conversation can be recorded using external equipment connected to the specic auxiliary output on the back panel.

Log the presenter

The user can create content review material by logging all presenter dialogue. Chose an auxiliary channel and turn down all individual channel gains for that channel. Turn the presenters auxiliary channel gain to the required level, set the master gain and use in POST mode. All on air material from the the presenters mic can be recorded from the auxiliary output on the back panel.

To avoid the patches of silence that would occur while audio or jingles are playing, use the remote control start and stop signals that are used to trigger the CD player, jingle player etc to also trigger the logging equipment if this option is available. Find out more about the remote control ports in chapter 4.

S1 User Handbook

MIXER APPLICATIONS

Create a talkback source

If you require multiple talkback sources, create a custom talkback mix on an aux channel and set is to PRE. Connect the Aux Output L to the channel 1 LINE input. After connecting the presenters Mic to channel 1, Use SCi (to nd out more about SCi, turn to section 4) to congure the talkback source to channel 1 Line and lock the channel 1 source button to Mic Input. This will prevent a loop back connection.

Use an auxiliary bus to create a clean feed for a hybrid unit

If the user would like to use a second hybrid, an auxiliary channel can be used to create a clean feed return. Turn the gain to all channels that are being broadcast to the required levels except for the channel which is receiving the audio from the second hybrid. Select POST so that everything that is heard has been mixed correctly. This channel should be muted. Connect the left channel of the auxiliary output to the the second hybrids clean feed input. If presenter would like to talk to the caller o air, turn o the presenter channel and fade in. This will allow the the presenter to be heard on the auxiliary bus but not on the PGM output. The presenter can press CUE PFL on the second hybrid channel to listen to the caller.

User Guide – Section 3-4 External equipment and the S1

Most of the equipment needed such as microphones, headphones and CD players are selfexplanatory. Occasionally you may need extra external equipment to really make the most of the mixer. Here are a few suggestions:

Headphone distribution ampliers

If the application requires more than one set of guest headphones, then a headphone distribution amplier is required. This will take one headphone output and create multiple new outputs from it, without aecting the signal or line impedance. Simply take the output from the guest headphones socket and connect it to the distribution amplier. It is recommended that you use the SONIFEX RB-HD series.

Microphone ampliers

Some applications may require more microphone inputs. If this is the case you could use the Line inputs with dedicated microphone amplier. Connect your microphone to the amplier’s input and connect the amplier’s output to the required line input. It is recommended that you use the SONIFEX RB-MA series.

S1 User Handbook

MIXER APPLICATIONS

Telephone hybrid

Use a telephone hybrid to open the show up to interaction with the outside world. A hybrid allows you to receive phone calls and send them to your mixer as audio. Connect the hybrids audio output to the mixers telco channel (channel 5) and connect the channel’s clean feed output to the line input on the hybrid. The mixer has been designed to work with the SONIFEX HY-03.

On-Air Light

The On-Air light, also known as Mic Live, is used to indicate to everyone inside or outside of the Control Room and/or Studio that microphones are live and on-air. A set of latching relay contacts, activated by a control room mute, are available on the Talkback 9 way D type socket on the rear panel of the mixer for the Control Room On-Air light. See the pin-outs of the talkback interface for details. Shown below is an example of connecting the latching relay contacts on the talkback interface to a SONIFEX RB-LC3. The remote connection on the RB-LC3 is active low.

Mic Cue Light

The mic cue light is used to indicate to a guest, etc, situated in a talks studio, that they should speak. The cue light is usually green, and there is usually one per microphone. This should not be confused with a mic live light, which is red and there is one per studio or control room, also known as “On Air light” (see above).

Open collector outputs for each channel are provided on the Remote Connectors. See the remote connectors section for details

NOTE: It is vital that mains voltages are NOT connected to any of the connectors on the mixer. If your On-Air light is to be mains operated then you should use a suitable optoisolated solid-state mains relay. The SONIFEX RB-LC3 Light/Power controller is a suitable unit that will control up to three On-Air lights and/or Mic cue lights.

Voice Processors On Mic Channels

To use an outboard eects unit with a microphone, for example, a voice processor an auxiliary bus could be used and returned through a spare input channel.

Use of the external inputs

The external inputs found on the rear panel are used to send audio to the presenter and guest headphones and to the monitor output. The external inputs can not be routed to the PGM output. Theses should be used to relay information information or audio to the presenter and guests which should be kept isolated from the transmission path.

Connect portable audio sources using DROP-IN

The drop in socket is used to add audio from an additonal external source such as a portable MP3 player. Connect the source to the mixer and the source will over ride all audio on Channel 7. This can be routed to the PGM output.

Meterbridge

The meterbridge is an expansion port that allows external meterbridge components to be connected. This includes a variety of dierent meter, timer and monitor panels. The meterbridge port can also supply up to 15V @ 200mA to external equipment if required. Appendix A (Page 44) contains the pin out and pin description for this port. For more information on meterbridge components, please contact Sonifex.

3. SCi control interface – Learn how to congure your mixer using the dedicated software interface, page 35.

User Guide – Section 4-1 Using the Remote Control

The remote control ports are available so that the user can control external equipment from the mixer. The two remote connectors on the rear panel contain all of the START & STOP outputs from the input channels. Each channel input has its own START and STOP remote controls except the microphone inputs which only have START outputs. In the eventuality that you require a microphone stop control signal, this could be congured using one of the general purpose outputs.

Remote Mode

The remotes can be congured in a variety of dierent ways:

• RemotesDisabled

- The remotes are not used and are not controlled by the desk

- If the stop control is set to continuous, then the stop signal will always be on

- If the stop control is set to pulsed, then the stop signal will always be o

• StartfromON&FaderUp

- The start signal is generated when the channel is live (when the ON button is

solid green)

- A stop signal is generated when the channel is not live

• TelcoMode

- The Telco mode sends the start pulse when the channel is initially armed (ON

button glows RED) This allows a hybrid to connect before the channel goes live.

- n this mode the stop signal is generated when the ON button is turned o (not

glowing)

S1 User Handbook

ADVANCED CONFIGURATIONS

• StartfromCUE/PFL&ON

- Aswell as the start signals being generated when the channel is live, a start

pulse can be congured to be sent when the CUE/PFL button is pressed. This option would allow the automatic start of a cd player for example, when the presenter prefades that particular channel.

• TelcoModewithCUE/PFL

- This operates the same as the telco mode except the CUE/PFL button can also

generate start and stop remote signals

Momentary/Continuous

Each remote output can be congured to operate in momentary or continuous modes.

Repeated Starts Mode

It is possible to congure the ON button to operate in a Repeated Start Mode. If this option is enabled, a start pulse will be sent when the channel initially goes live. If whilst the channel is live (ON button is green), the ON button is pressed again, an additional start pulse will be sent.

User Guide – Section 4-2 General purpose inputs and outputs

The S1 has ve General Purpose Inputs/Outputs (GPIO) available. Each GPIO has been designed to be very versatile & almost any operation with the mixer can be achieved when utilising them.

General Purpose Inputs

Each GPI can be congured to perform up to 10 dierent operations from a single input. For example, in a remote play out situation, you may want to:

* Force 4 channels ON with the faders forced up

* Force 4 channels to input 1

* Mute the Control Room Monitors

This conguration would utilise 9 of the 10 operations available for an individual GPI.

Options / Conguration

The Input can be congured to operate in several dierent ways:

* Momentary / Continuous GPI

* Active High / Low GPI

S1 User Handbook

ADVANCED CONFIGURATIONS

To Congure a GPIO please refer to the GPI: mode in the Serial Command Interface Section.

General Purpose Outputs

Each GPO can be congured to generate an output from up to 10 dierent internal controls. For example, a GPO could be congured to generate a global talkback function. The GPO would be setup so that:

* When microphones 2, 3 and 4 are all not live, generate a GPO continuous output

The GPO could then be linked back into one of the GPI’s with the Input Congured to:

* Force PFL on Mics 2,3 & 4

* Enable Auto CUE/PFL Guest

This would allow the guests to freely talk to each other until one of their mics goes live.

Options / Conguration

The Output can be congured to operate in several dierent ways aswell:

* Momentary / Continuous GPO

* Active High / Low GPO

Tally Back

In addition to the telco remote mode, the channel can be congured to show the state of the external equipment. Once the channel has been armed, the channel will ash green, until a GPI signal (tally back) has been received back to conrm that the external equipment is now online. This will then allow the channel to be opened. If the external tally is lost (ie a tbu goes oine), the mixer will wait for 1 second before muting the channel & returning to the green ashing state.

In telco mode, it is possible to use the telco mode to set up an external link and then switch over to use the other input on that particular channel. If the tally is lost whilst still monitoring the other side of the input channel, the on button shall ash orange at a 25% duty cycle, to show that the external link has been lost.

To re-setup the link, the user must switch to the channel with the telco mode, turn the channel o, & then turn it back on. When the tally is received from the external equipment, the orange/green ashing will stop.

Automation Tally

An automation tally can be used as a visual indication to the presenter that something is happening or about to happen. When an auto tally is congured on a playout system channel for example, the auto tally could be used to indicate to the presenter that the playout track is about to end. When the GPI becomes active the ON button will ash green.

To congure all GPIO and tally modes, please refer to the SCi section

GLOSSARY

9 Glossary

Attenuation The reduction of a signal level. Attenuation is usually measured in dB.

AES Audio Engineering Society.

AES/EBU Professional digital audio standard covering frame format,

connections and interfaces. Interface is usually on XLR sockets and plugs.

Balance The relative levels of the left and right channels of a stereo signal.

Cleanfeed A cleanfeed is the signal produced by the telco module, which is

used as the output to be fed back to a caller on a telephone line. A true cleanfeed is the sum of all the other signals, which constitute the programme output, except for the caller’s audio.

Clipping The onset of severe distortion in the signal path, usually caused by

the peak signal voltage being limited by the circuit’s headroom.

Common Mode Rejection Ratio

This is the ratio of the extent to which a dierential amplier will cancel noise, which is present on both inputs, compared to its ability to amplify the wanted signal.

Cross-talk This is the amount of an unwanted signal which appears, or is

induced, on a dierent or unassimilated signal. The problem is usually most prevalent with adjacent channels.

CUE - See PFL.

dB (decibel) A ratio of two voltages or signal levels, expressed by the equation:

dB=20LOG(V1/V2) Adding the sux “u” denotes that the signal is relative to 0.775V RMS. Adding the sux “v” denotes that the signal is relative to 1V RMS

EQ EQualisation. This is the method of cutting or boosting selected

bands of frequencies in the signal.

Gain The degree of amplication, or attenuation applied to a signal.

Hybrid A device that allows a telephone line to be connected to a broadcast

desk in such a way that the caller may hear the programme output without the caller’s voice being re-introduced onto the phone line. Essentially a two to four wire converter.

LED Light Emitting Diode.

PAN This controls the levels (usually of a mono signal) sent to the left and

right outputs and is an abbreviation of “panorama”.

PFL (CUE) Pre Fade Listen, also called CUE. A function that allows the operator

to monitor the pre fader signal independently of the programme output.

S1 User Handbook

GLOSSARY

S/PDIF Sony/Phillips Digital Interface. Domestic digital audio interface

standard using phono connectors or optically using bre-optic connectors.

T/B Talkback (and reverse talkback, Rev T/B). This is the ability for two or

more studios to communicate with each other o-air.

Telco TELephone COmmunication. The telco channel is used by the

presenter to talk to telephone callers via a hybrid or TBU.
