Congratulations on purchasing the PSR1212, a highly advanced twelve-by-twelve digital matrix mixer with audio processing. It utilizes an internal macro language and 32 user-definable presets to quickly adapt to a variety of sound reinforcement and room-combining applications in auditoriums, stadiums, theatres, gymnasiums, hotel/convention centers, conference rooms, training rooms, and boardrooms.

The PSR1212 facilitates local and remote PC setup and diagnostics, logic outputs, and automatic gated microphone operation. Gating parameters for microphone inputs can be individually customized, while automatic gain control keeps the overall sound level consistent. Eight of the 12 channels can be configured as an automatic microphone mixer.

All microphone mixing parameters can be customized and any combination of inputs can be routed to any combination of outputs, with attenuation adjustments at each cross point. This allows flexibility in accommodating different applications and customer requirements.

Adjustments in routing, level, and other functions can be made through presets activated through a closure on the rear panel, an RS-232 serial interface, or a control panel through the RS-485 port.

The PSR1212 features eight audio processing blocks, each with 15 filters. Each filter can be configured as a parametric equalizer, high pass, low pass, CD horn, high shelving, low shelving, all pass, or crossover. This allows you to tailor the PSR1212’s audio response to optimize the audio quality and fidelity in a wide variety of venues.

The GPIO (general purpose input/output) allows switching among any of 32 user-stored presets. This gives you real-time flexibility to meet a variety of audio reinforcement requirements.

Network-based interconnectivity allows up to eight PSR1212s to be connected and controlled as a single unit, allowing microphone coverage in applications requiring up to 64 mics.

The PSR1212’s Macro Pro™ scripting language allows the unit to function without the need for an external controller. However, it can be easily interfaced to the ClearOne Control Panel or XAP IR Remote via either of the two RS-485 ports. The unit can also interface with a PC or external controller through the RS-232 port.

Introduction ~ Controls and Connections

Power is supplied through the RS-485 ports to the remote Control Panels from the PSR1212. This power is limited to a total of 300mA at 15 volts for each connector. Over-current protection is provided on the +15V pins to prevent damage in the event of shorting. External power can be provided to control devices when more current is required. See page 89 for maximum cable run distances when using ClearOne Control Panels.

D. Control/Status Ports A and B. These two female DB-25 connector are used

to connect control devices to the PSR1212. The control devices have access to the command set for the PSR1212 and can be used for common functions such as volume control, muting, preset change, room combining, etc. Devices can be connected to either port.

For instructions on how to program the control and status pins, see the GPIO section on page 75. The default settings allow control and status of inputs, outputs, volume, and presets. These pins are active low. The 32 presets can also be activated via these connectors. For pinout and default information, see Appendix B.

E. Outputs 1–12. These three-pin Phoenix connectors are for connection of

twelve line-level balanced outputs with three-pin Phoenix connectors. These outputs are typically used for connection to VCRs, tape recorders, amplifiers, and other audio devices. These outputs can be configured to contain any combination of gated and non-gated inputs. The nominal output level is 0dBm.

F. Inputs 9–12. These Phoenix connectors are for connection of up to four

line-level inputs. These are typically used for connection of VCRs, tape players, CD players, and other audio sources. They can be routed to any output or multiple outputs. Nominal level is 0dBu.

G-H.Expansion Bus In/Out. This RJ-45 connector is part of the expansion bus

(E-bus), which allows up to eight PSR1212 or XAP 800/400 units and up to 16 XAP TH2 units to be networked together. The E-bus consists of two buses: one for control, the other for passing audio and mic information (see Control bus, page 7). Using Cat 5 twisted-pair cable, you can separate adjoining units up to 80 feet (24 meters). See the diagram on page 11.

I. RS-232. This female DB -9 serial port is for interconnection between the

PSR1212 and a PC, modem, or other external control device. For serial protocol, see Appendix B: Connector Pinouts.

Introduction ~ Networking

Networking

The latency or propagation delay is <1ms.

✍

Expansion bus

The digital mix-minus expansion bus (RJ-45 LAN) is used to connect up to eight PSR1212s (or XAP 800/400s and 16 XAP TH2 units), where the total number of microphone inputs does not exceed 64. The maximum distance between interconnected PSR1212 or XAP 800/400 units is 80 feet (24 meters). Connecting a XAP TH2 must not increase the cable length between two PSR1212s, XAP 800s and/or XAP 400s beyond 80 feet. ClearOne recommends that category five twistedpair (10BaseT LAN) cable be used.

The expansion bus (E-bus) allows audio routing between destinations on the E-bus network. The E-bus contains 12 independent digital audio buses labeled O–Z which can route mic or line level inputs in any combination across the E-bus network. The O–Z buses are divided into two groups (O–R and S–Z) based on their capabilities and default settings. The E-bus also contains four PA adapt reference buses, four global gating buses, and one control bus.

• O–R buses. These four audio buses are defaulted as the mic mix buses; they

can communicate the NOM count and mic mixing parameters across the

network to other PSR1212s. All gated mics are routed to the 0 bus by default.

• S–Z buses. These eight buses are defaulted as auxiliary mix buses. They are

used to route auxiliary audio, such as from a CD player or VCR, to and from

other units on the network. These buses are also used as mic mix buses when

NOM count is not required.

• PA Adapt Reference buses. These buses allow an input from a PSR1212 to

reference an output on another linked PSR1212 or XAP 400/800. See PA

Adapt and AEC Reference on page 37 for more information.

• Global Gating Groups A–D buses. These mix-minus buses are defined as

microphone gating groups which support first-mic priority, maximum

number of mics, etc. and work across all linked units. Unlike the audio

buses, they contain only mic status and gate parameters. See page 39 for

more information about gating groups.

• Control bus. The control bus is an independent channel from the E-bus’s

audio channel; it uses a different pair of wires on the same E-bus cable. This

allows control information to pass even if the units are not using the audio

link. The PSR1212 supports the full set of commands through the control bus.

Technical Services Group ~ 1-800-283-5936 (USA) ~ 1-801-974-3760

To connect the unit

1. Place the unit in a standard 19-inch rack and attach it securely.

2. If you are using a custom controller for control and status, plug it into the DB-25 Control/Status A or B port [D].

If you are using an external RS-232 controller, connect it to the RS-232 port [I].

3. Wire the inputs and outputs to the PSR1212 using the provided threeterminal Phoenix push-on connectors. These connectors are designed for easy wiring; simply insert the desired wire into the appropriate connector opening and tighten down the top screw.

• Inputs 1–8 [B] Mic or line level inputs

• Inputs 9–12 [F] Line level inputs only

• Outputs 1–12 [E] Line level outputs

4. If you are using a ClearOne Control Panel or XAP IR Remote, wire it to the RS-485 port [C] using one of the provided four-terminal Phoenix push-on connectors.

5. Plug in the PSR1212 to complete the installation. The power output [A] will operate at any level between 100–240VAC and 50–60Hz.

If you are installing only one PSR1212 and are not connecting it to any other XAP or PSR1212 units, you have completed the hardware installation.

Technical Services Group ~ 1-800-283-5936 (USA) ~ 1-801-974-3760

Expansion bus connections

Using the Expansion Bus ports (RJ-45), you can connect up to eight PSR1212s or XAP 800/400s and 16 XAP TH2 units, where the total number of microphone inputs does not exceed 64. Make connections between units in daisy-chain fashion using the short RJ-45 jumper. If your units are further apart, use category five twisted-pair cable.

The maximum distance between interconnected PSR1212 or XAP 800/400 units is 80 feet (24 meters). Expansion bus cable length is calculated between PSR1212s and XAP 800s/400s.

To create an expansion bus network

1. Plug the expansion bus ter minator in the Expansion Bus In connector of

the first unit in the network.

2. Connect the RJ-45 jumper cable (or Cat 5 twisted pair cable) to the

Expansion Bus Out connector of the first unit in the network and

Expansion Bus In connector of the second unit. Continue connecting units

in the same fashion.

3. Plug the expansion bus terminator in the Expansion Bus Out connector on

the final unit to complete the network connections.

If the E-bus network is not connected properly, the front panel LEDs will

flash on the units that are physically connected to the network. To cor rect

the problem, check for broken connections and reconnect the expansion bus

cables.

Figure 2.4. E-bus connection diagram

Networking Units

If connecting to other units, make sure the first

unit in your E-bus network is a PSR1212 or XAP 800/400 instead of a XAP TH2.

✍

RS-232 system-wide control can be provided by any PSR1212 or XAP 800/

400 unit in the network.

Device IDs

Once your expansion bus connections are made (and if you have more than one PSR1212 at a site), you need to set up a unique expansion bus device ID number—a network address—for each PSR1212 on the network. As shipped from the factory, all PSR1212s are set to device ID 0.

To assign device IDs

Press the front-panel

Enter

button, then scroll through the menu until the

System

menu is visible.

2. Press

Enter

, then scroll through the menu until

Device ID

is visible.

3. Press

Enter

, then scroll through the eight (0–7) options. When the desired

device ID is visible, press

Enter

to select it. (You can also set the device ID in

the Unit Properties window of G-Ware software. See page 25.)

4. Repeat this process for each PSR1212 on the expansion bus network.

Mixer mode

There are two mixer mode settings: slave (default) and master. A master unit is not required in a networked system and in most installations, all units will be slaves. Master units ignore audio from upstream units. This prevents audio from being received from units above the master unit in the network. However, global control of the system is still maintained by whichever PSR1212 or XAP 400/800 unit is connected to a control device through its RS-232 or RS-485 ports. Control is not affected by master/slave designations.

In Figure 2.5, the third unit in the network is a master. It prevents the audio from the first and second units from being passed down the network chain. Likewise the second master unit in the network will not pass on the audio from the unit before it. The third unit provides system-wide control through a connection to its RS-232 port.

To select a mixer mode

1. Press the front panel Enter button and scroll through the menu until System

menu is visible. Press Enter to select the menu.

2. Scroll through the System menu and select Mixer Mode.

3. Select the mixer setting you want to use.

Repeat for additional units.

If the same device ID is assigned to more than one

unit on the E-bus network, the Meter LED “+12” will flash red and the Mic LEDs “1,” “2,” “4,” and “8” will flash green on the affected units. To correct the problem, change the device ID on one of the conflicting units.

Installation ~ LCD Programming

Technical Services Group ~ 1-800-283-5936 (USA) ~ 1-801-974-3760

The PSR1212’s front panel is intuitive to operate, thanks to its simple interface: a 2x16 character LCD, menu buttons, and a peak-level LED bar meter. Although most of the PSR1212’s features are programmed with G-Ware software (see page 23), the front panel can be used for simple adjustments and meter monitoring.

When power is applied to the PSR1212, the LCD panel will first read INITIALIZING. If an error is displayed, contact technical support. When initialization is complete, “PSR1212” is displayed on the top line and “Unit 0” is displayed on the bottom line.

LCD menu tree

The menu tree features five main menus, each with submenus. These branches typically end when an adjustable parameter or viewable value is reached. The diagram below shows the LCD menu tree.

LCD Programming

Pressing Esc at the top of the tree does nothing.

G-Ware software is required to complete system setup.

✍

Figure 2.6. LCD menu tree

Installation ~ LCD Programming

The five main menus are: System, RS-232, Meter, Inputs, and Outputs. All submenu items are arranged under these menus. Use the Enter button to select items and the ▲ and ▼ buttons to scroll through menus and submenus. When the last menu item is reached, the display scrolls back to the beginning of the list. The Esc button allows you to back out of the menus.

To adjust a parameter

1. Scroll to the parameter you want to adjust. Press Enter to select the

parameter. The parameter will flash when selected.

2. Adjust the value with the ▲ and ▼ buttons. As the value is adjusted, the

parameter is updated immediately.

3. To store the new value, press Enter. To discard the change and revert back

to the old value, press Esc.

If the Meter button is pressed while a parameter is being adjusted, the LCD

will switch to the Meter menu.

System menu

There are eight system-level parameters (see Figure 2.6): Select Preset, Run Macro, Lock Panel, Set Passcode, Device ID, Unit ID, Mixer Mode, and Fir mware Version.

Select Preset

The Select Preset menu item allows for one of 32 preprogrammed presets to be selected for PSR1212 use. To select a preset, scroll through the numbered presets (1–32) until the desired preset is visible, then press Enter to run the preset.

Run Macro

The Run Macro menu item allows you to execute a macro. To select a macro, scroll through the numbered macros (1–255) until the desired macro is visible, then press Enter to run the macro.

Lock Panel

The front panel can be locked to prevent unauthorized adjustments to the PSR1212. To lock the front panel, use the ▲/▼ buttons to select Lock Panel from the System menu, and press Enter. Lock Panel selections are Off, On, or On at Timeout. Press Enter to enable your selection.

Technical Services Group ~ 1-800-283-5936 (USA) ~ 1-801-974-3760

Installation ~ LCD Programming

Menu items can still be scrolled through when the

panel is locked. However, settings cannot be entered until the panel is unlocked with the appropriate passcode.

✍

To unlock the front panel, attempt to adjust a parameter. The PSR1212 will prompt for the passcode. Upon entering the fifth character (if entered correctly), the front panel will unlock. The default passcode for all boxes is ▲▲▼▼Enter.

Set Passcode

Once the PSR1212 is unlocked, the passcode can be changed. Before the PSR1212 will allow passcode changes, the new passcode must be entered, then re-entered to validate the new passcode.

The front panel passcode can also be set (and reset) within G-Ware. See page 26 for more information.

Device ID

The PSR1212’s device ID is set from this menu. There are eight device ID selections to choose from (0–7). Select the network position you want to use. Within a single site, you must assign different device ID numbers for each PSR1212 unit. See Device IDs, page 12.

Unit ID

The Unit ID menu selection allows you to access the read-only address set at the factory. This unique ID number identifies your particular PSR1212 unit and cannot be changed.

Mixer Mode

This setting allows you to set to master or slave mode. See page 12 for details.

Firmware Version

This menu selection allows you to view which firmware version is being used. This information cannot be changed.

RS-232 menu

There are four submenus under the RS-232 menu: Baud Rate, Flow Control, Enable Modem, and Clear Password.

Baud Rate

This parameter allows you to set the PSR1212’s baud rate to 9.6kbps, 19.2kbps,

38.4kbps, or 57.6kbps. Default is 38.4kbps. Select the baud rate you want to use, then press Enter.

Installation ~ LCD Programming

ClearOne recommends that you leave Flow Control enabled.

✍

The modem initialization string can be set only via

the MINIT serial command (see page 113 or the G-Ware software). It cannot be set through the front panel LCD.

✍

You can set the modem password using the

MPASS serial command (see page 114) or in G-Ware (see page 26).

✍

Flow Control (hardware)

The PSR1212 uses the RTS and CTS pins on the RS-232 port to regulate the transmission and reception of data. You can enable or disable flow control on the front panel of unit and select the flow control type in the Site Properties window of G-Ware (see page 23). If you select On (default) from the front panel menu, select Hardware as the flow control type in the Site Properties window. If you disable flow control on the front panel, select None in the Site Properties window. When None is selected, the PSR1212 ignores flow control, making the connected external control device ensure that data is not lost. Software flow control (Xon/Xoff) is supported by the XAP/PSR units and is used only with a pass-through device, such as a modem.

To avoid communication er rors, ClearOne strongly recommends that you

connect all DB-9 pins and enable flow control when connecting to a PC.

Enable Modem

This parameter configures the RS-232 port for connection of a modem. When On is selected, the PSR1212 will send an initialization string to the modem on power-up and require a password before data transfer is allowed through the port. When Off (default) is selected, the password is disabled.

To use the PSR1212 with a modem

1. Match the baud rate of the modem to that of the PSR1212.

2. Turn off Serial Echo on the modem.

3. Turn off the modem’s response mode (e.g., no OK messages, ring, etc.).

4. Enable auto-answer on the modem.

Clear Password

This parameter allows you to erase the serial port (modem) password in case it has been forgotten. Select Yes to keep the current password or No to erase it. Press Enter to enable your selection.

Meter menu

There are four submenus under the Meter menu: Inputs, Outputs, Processing and Default Meter. The meter selection determines what is shown on the front panel peak-level LED display. When the meter is selected in the LCD menu tree, the LCD displays peak level indications as well. Use the ▲ and ▼ buttons to select the Meter menu, then scroll through the options and press Enter when you reach the desired option.

G-Ware has three modes: Configuration, Preset, and Macro Recorder. Configuration is used to configure the unit and is the default mode. The Preset and Macro modes are discussed in Chapter 4: Advanced Configuration. You can switch between modes by clicking on the corresponding toolbar button. The current mode is displayed on the status bar.

There are two main configuration screens, the Flow Screen and the Matrix

Screen. All unit configuration and audio routing is accessed through these screens.

Flow Screen

The G-Ware Flow Screen is the main access window for G-Ware’s features and functions. Using the menus and toolbar at the top of the screen, you can access general configuration windows. Unit specific configurations are accessed through the buttons and labels on the Flow Screen itself. If you have multiple units, click on the unit icon in the Site pane to access that particular unit’s Flow Screen.

The Flow Screen shows a detailed block diagram of the path of the audio signal, presenting a graphical explanation of each stage of audio processing. Mic and line inputs, outputs, expansion buses, and processing block configuration windows can all be accessed from this screen. The PSR1212 Flow Screen has seven icons and buttons at the bottom of the Flow Screen which open the following unit programs: Remote Builder, Gating Control, Signal Generator, Preset Mode, Macro Editor, Meters, and GPIO Builder.

Copying and pasting settings

G-Ware has shortcut menus which appear when you right-click a selection or program window in G-Ware. These shortcut menus provide quick access to options such as Print, Copy, and Paste that pertain only to that selection or screen region. Using the Copy and Paste commands, you can copy and paste unit data such as a single setting or the entire unit’s settings depending on which window you are in. For example, if you are in the Inputs 1–8 window, using the shortcut menu will allow you to copy and paste all of the input settings to other inputs. You can also use keyboard shortcuts (Ctrl+C and Ctrl+V) to copy and paste settings. If you want to apply all settings of a selected input to the rest of the inputs, select Apply to All.

Safety Mute

The Safety Mute feature in G-Ware enables you to mute all outputs if feedback or audio problems occur during the configuration process. To use Safety Mute, click the Safety Mute button on the G-Ware toolbar. Then find and correct the cause of the problem. Click the Safety Mute button again to unmute the outputs.

Status bar

There are two status lights at the bottom of the G-Ware window representing the unit and the site. The lights illuminate in various colors to indicate current status.

• Solid green. The item being configured is synchronized with the hardware.

• Solid red. The information being configured is saved in the sof tware offline.

• Flashing red. The information is not saved or there is no hardware connection.

• Solid yellow.

• Flashing yellow.

There is a communication error. In this instance, you should disconnect from the unit and reconnect. The Message Log will indicate the error that occurred. See page 73 for more information.

Matrix Screen

The Matrix Screen is used to route audio to one or more destinations (outputs, expansion bus, or processing). Any number of connections to outputs can be made in the matrix. The Matrix Screen can also be used to access the Input, Output, and Processing configuration windows by clicking on the buttons along the top and left sides of the routing matrix.

A colored cell in the routing matrix marks the intersection or cross point of the routing from input to output. The color of the cross point cell identifies the input type: yellow = gated mic input, blue = non-gated mic input, and green = all other inputs. The amount of attenuation is also shown in the cross point cell. Black cell are restricted routing paths which prevent E-bus and Processing channels from being routed back to themselves.

The numbers and letters along the top and left side of the matrix show the cross point coordinates. The input number or letter and the output number or letter will be highlighted blue for the selected cross point.

All inputs and outputs are labeled to make it easier to identify channels. Clicking on a label will open a labels window where you can change the channel labels.

Audio is routed in the Matrix Screen (see Figure 3.20 on previous page). To access the Matrix Screen, click on the Matrix button on the Flow Screen. To retur n to the Flow Screen, click the Flow Screen button.

The PSR1212 routing matrix has 32 possible input sources and 32 output destinations, with level control at each cross point. Any input or combination of inputs can be routed to any output or any combination of outputs. To clear the matrix, click the Clear Matrix button located above the Routing Key.

To route an input, click in the routing matrix at the intersection between the input and the output. A mic input can be designated as gated (yellow) or non-gated (blue) by clicking repeatedly in the cross point. All other input cross points will be colored green.

Expansion bus O–Z routing

Audio on any PSR unit in the E-bus network can be placed on the bus or taken off the bus and routed to any destination within the unit. The PSR1212 has 12 digital mix-minus buses:

• O–R buses are defaulted as the mic mix buses and can communicate the

NOM count. Gated mics are default routed to the O bus.

• S–Z buses are defaulted as the auxiliary mix buses. They are used to carr y

auxiliary audio such as that from VCRs and CD players. These buses are

used as mic mix buses when NOM count is not required.

Process A–H routing

There are eight processing blocks on the PSR1212 (Processing A–H). With these processing channels, you can apply filters, EQ, or other processing settings to an input or a group of inputs which can then be routed to a single output or group of outputs. See page 47 for more information on processing settings.

Cross point attenuation

Right-click on a cross point to open the Cross Point shortcut menu. Click Cross Point Enter to open the Cross Point Attenuation Dial window.

Inputs 1–8

To open the Inputs 1–8 configuration window, click the Inputs 1–8 button on the Flow Screen. The In 1–8 button on the Matrix Screen will also open this window. These inputs are balanced and support both mic and line levels.

To select an input channel, click a blank area in the input pane. If you click on the input label, a secondary window will open allowing you to rename the input. The background color for the selected input channel will be light gray. The many configurable properties of mic inputs are defined in this section.

Mute

Mute mutes the input channel. The light on the button illuminates red when Mute is activated. Default is Off (unmuted).

AGC

AGC toggles on and off the automatic gain control. AGC keeps softer and louder input audio to a consistent level. It does this by attempting to adjust the signal to a fixed +4dB target level. If the signal level and the +4dB target level both fall within the AGC’s 12dB range, the AGC achieves the +4dB target level. If the signal level is more than 12dB away from the +4dB target level, the AGC sets the level

12dB closer to the target. AGC occurs after the gain and filter settings in the audio signal path. AGC default is Off.

P Pwr (Phantom Power)

Phantom Power toggles the phantom power on and off. Phantom power is an auxiliary power source to power certain types of microphones. The PSR1212’s phantom power voltage is 24VDC. Default is On.

Filters

The Filter button on the selected input in the Inputs 1–8 window opens the Filter Graph setup window. Each mic/line input has four configurable filters that can be used as filters or equalizers. By default, they are not enabled and the filter types are not defined. Below is a description of each feature in the window.

Active Filter

Active Filter selects among filters on the graph. Note that no filters exist until you click Add Filter (see Figure 3.26).

Type

Use the Type list to select from the following input filters: All Pass, High Pass, Low Pass, Notch, and PEQ. G-Ware features other filters which are configured in the Processing section of the software (see page 47).

• All Pass. Frequency range is 20Hz to 20kHz with resolution to 1Hz or four places (whichever is larger).

• High Pass. Selectable frequency cutoff is 20Hz to 20kHz, in 1Hz increments. Rolloff is 12dB/octave. Level is fixed at 0dB.

Figure 3.26. Inputs 1–8 Filters window

System Configuration ~ Inputs and Outputs

Technical Services Group ~ 1-800-283-5936 (USA) ~ 1-801-974-3760

• Low Pass. Selectable frequency cutoff is 20Hz to 20kHz in 1Hz increments. Rolloff is 12dB/octave. Level is fixed at 0dB.

• Notch. Center frequency range is 20Hz to 20kHz with resolution to 1Hz or four places (whichever is larger). Bandwidth is from .05 to 5 octaves in .01 octave increments. Level is fixed at -80dB.

• PEQ (parametric equalizer). Center frequency range is 20Hz to 20kHz with resolution to 1Hz or 4 places (whichever is larger). Bandwidth is .05 to 5 octaves in .01 octave increments. Level range is -15 to +15dB in 0.5dB increments.

Frequency. Use Frequency to select the center frequency (in Hertz) for the filter

you are configuring. Range is from 20Hz to 20kHz. Default is 1kHz.

Gain. Gain adjusts the gain value from -18 to 18dB, in .5dB steps. Default is 0dB. Q, or Quality factor. Q, or Quality factor, selects the ratio of the center frequency

divided by the bandwidth. Q reflects an inverse relationship to the bandwidth, and adjusts from .02:1 to 40:1 on the PSR1212.

Bandwidth. Bandwidth establishes the difference between the upper and lower

points of a filter’s audio passband.

Bypass. The Bypass box, when selected, bypasses the selected filter. Phase. Phase generates—on the graph—the phase relationship of the graphed

frequency response.

Bypass All. Bypass All bypasses all filters. Add Filter. Add Filter adds a filter to the graph, centered at 1kHz and 0dB. Remove Filter. Remove Filter removes the selected filter from the graph.

Table View

Table View toggles between the Graph and the Table views of the Inputs 1-8 Filter window. The Table view displays the selected filter settings in table format. You can configure filters from this view as well as in the graph view.

System Configuration ~ Inputs and Outputs

Technical Services Group ~ 1-800-283-5936 (USA) ~ 1-801-974-3760

To configure filters

1. In either the graph or table view, select the filter type from the Type list.

Note that the configurable filter parameters displayed depend on the selected filter type.

2. Click Add Filter to add a filter to the graph or table.

3. Configure filter parameters using the previously described lists. If you are using the graph view, you can click on the node and drag it to the location you desire on the graph.

4. Click Close to exit.

Gate

The PSR1212 has unique gating parameters which control microphone activation. The Gate button on the selected input in Inputs 1–8 window opens the Gate configuration window where you can establish the gating parameters for the input.

Activation

There are three mic activation settings: Auto Gate, Manual On, and Manual Off.

• Auto Gate determines mic gating based on the input level and gating settings for the gating group the input is assigned to. It contributes to and is affected by all gating group settings such as NOM, chairman override, etc.

• Manual On activates the mic, provided it does not exceed max NOM requirements of the gating group that the input is assigned to. It is included in the NOM count.

• Manual Off deactivates the mic.

Figure 3.28. Gate window

System Configuration ~ Inputs and Outputs

Technical Services Group ~ 1-800-283-5936 (USA) ~ 1-801-974-3760

Chairman Override

Chairman Override provides gating priority for this mic input over any other mic input within the same gating control (mixer) groups. When a mic with Chairman Override enabled gates on, all mics which don’t have Chairman Override enabled will gate off. Default is off.

Adaptive Ambient

Adaptive Ambient adjusts the ambient reference level as noise and room conditions change. When adaptive ambient is on, the mic channel monitors the ambient noise level on the input and adjusts the ambient level reference automatically. This means that the gate threshold level automatically increases or decreases based on background noise. If Adaptive Ambient is turned off, the input will use the fixed ambient level specified in the Ambient Level box as its gating reference. Default is on.

PA Adaptive Mode

PA Adaptive Mode uses loudspeaker audio level on a specified output as the new ambient level when audio is present at the power amplifier. This prevents loudspeaker audio from gating on the mic, while still allowing people in the room to gate on microphones as they speak—provided that their voices are louder than the loudspeaker audio. For example, you might decide to play background music from a CD player during a presentation. PA Adapt Mode allows you to use the output routed from the CD player as the ambient reference to prevent the CD player’s audio from gating on microphones. An output must be specified as the PA Adaptive Reference for each mic in the system. Default is on.

Gate Ratio

Gate Ratio specifies how much louder the audio level must be above the ambient level before the channel gates on. The gate ratio range is from 0 to 50dB. Default is 15dB.

Hold Time

Hold Time determines how long the channel stays gated on after the audio is below the threshold. The hold time range is from .1 to 8.0 seconds. Default is .3 seconds.

Off Attenuation

Off Attenuation sets the amount of level reduction applied to a channel when it is gated off. The range is from 0 to 50dB. Default is 12dB.

Ambient Level

Ambient Level is available only if the Adaptive Ambient feature isn’t enabled. Use

System Configuration ~ Inputs and Outputs

Technical Services Group ~ 1-800-283-5936 (USA) ~ 1-801-974-3760

Ambient Level if you want to specify a fixed reference point rather than one that adjusts for background noise. The range is from -80 to 0dB. Default is Off.

Decay Rate

Decay Rate determines how fast a channel gates off after the hold time expires. Default is Medium.

PA Adapt and AEC Reference

When using the PA Adaptive mode, the output that carries this information, i.e. the reference output, must be defined. Select the reference output from the PA Adapt and AEC Reference list. Any one of the 12 outputs, four expansion bus references, or four virtual references can be selected.

If you select an

expansion bus reference

, the Define PA Adapt/AEC Expansion Bus Ref window opens so you can identify which expansion bus output you want to use as the PA reference. You can also open this window from the toolbar.

System Configuration ~ Inputs and Outputs

Technical Services Group ~ 1-800-283-5936 (USA) ~ 1-801-974-3760

If you select a

virtual reference

, the Virtual Reference window will open. You can

also open this window from the G-Ware toolbar.

Use this window to select which signals will be included in each of the four Virtual Reference points. The routing matrix portion of this window cannot be edited. Virtual re f erences are used when you need to reference multiple outputs. For example, if you have multiple zones in a boardroom or large meeting room, you might want the mics to reference two zones. By using a virtual reference, PA Adapt will be able to reference both signals. This means you don’t need to use a dedicated output to combine signals.

To create a virtual reference

1. Select the input signals you want included in each virtual reference by

clicking the cross points.

2. Because AEC requires a physical output reference to track output gain

changes, you need to select an output reference for AEC to function properly

with a virtual reference. Use the lists at the bottom of the window to select

which output you want AEC to use to track gain changes.

3. Click Close to exit the window.

Gating Group Select

In addition to specifying gating characteristics for each mic input, you can assign the inputs to a gating group for greater flexibility and control. When inputs are assigned to a gating group, the gating information from the inputs is used to control how the entire mixer behaves.

The PSR1212 features four internal gating groups (Internal 1–4) and four global gating groups across the expansion bus (Global A–D). Microphones can be used in only one gating group at a time. If an input is not assigned to a gating group, that mic’s gate properties are independent and have no effect on any other gating group. When gating groups span two or more units (global gating groups), the settings must be the same for each unit attached to the global gating group. Mic inputs are routed to Global Group A by default.

To assign a gating group

•

Select the Internal or Global group the mic input will belong to or select

None.

To configure gating group settings

1. Click the Gating Control button on the toolbar. This opens the Gating

Controls window.

2. Select the Max # of Mics (default is 4).

This sets the maximum number of microphones that can be gated on at any

one time within a gating group. For internal groups, the maximum number

of mics can be from 1 to 8. For global groups the maximum number of mics

will vary depending on how many mic inputs are assigned to the gating

group (up to 64). You can also select All for the global groups—which

means all mics could gate on.

3. Leave 1st Mic Priority selected (default) to enable this feature; otherwise, clear the selection to disable it. ClearOne recommends leaving this setting on.

This setting helps maintain maximum audio intelligibility by allowing only one mic to gate on to a participant’s voice. 1st Mic Priority allows more than one microphone to be activated at the same time—it simply restricts mics from gating on to the same audio source. It does this by determining the audio level received by all mics when the first mic is gated on. This audio level is then used as the ambient level for the gating group. If this feature is disabled, usually two or more microphones gate on when only one person speaks.

4. Select last-mic operation from the L ast Mic Mode list. There are two options for Internal groups: Last On and Off. If you are configuring Global groups, you can select from the mic inputs assigned to the Global group in addition to Last On and Off.

Last On leaves the mic that was activated last full on until another mic input is gated on. The Input setting allows you to select which mic input the PSR1212 leaves on when all mics gate off. In a boardroom or meeting room application, this feature can be used to specify the chairperson’s mic as the last mic on. If Off is selected, all mics will gate off when no audio is present.

5. Click the Gating Group label to change the group names.

Gain

The Coarse and Fine sliders on the selected input on the Inputs 1–8 window are used to match the level settings for microphone inputs and to adjust input volume level.

• Set the Coarse gain to 55dB for a mic input, 25dB for active equipment that requires an input between mic and line level, or 0dB for a line level input.

• Use the Fine gain slider to adjust input volume level.

You can also enter the

level directly in the 0.0dB box.

Min/Max limits

Use the yellow and blue upper and lower limit arrows on the Fine gain scale to create minimum and maximum gain level limits. These limits apply only when using relative gain commands; absolute gain commands can exceed the min and max limits. Min/Max limits apply to all serially connected control devices and prevent users from adjusting levels beyond the min/max levels, provided relative gain commands are used.

Optimizing input gain structure

How you adjust an input’s gain directly affects sound quality. The optimal input gain setting is one which is adjusted as high as possible above the noise floor without introducing clipping. Clipping can cause distortion which can damage amplifiers and loudspeakers.

To adjust the input level properly, place a signal on the input at the maximum level it will generate. Adjust the input gain until the peak level of the input, as shown on the Input meter, just begins to enter the red (clipping) zone, then reduce the gain slightly until peaks no longer climb into the red zone. This setting will ensure that the PSR1212 maximizes the signal-to-noise ratio without clipping the signal.

Meters

There are four meters on each mic/line input to assist with setup and level control. Select the meter check box to enable the meter. All input meters are peak-level.

Pre Gain

Pre Gain meter indicates the input’s level before gain adjustments. Meter range is from -85 to -35dB when 55dB gain is selected; -55 to -5dB when 25dB gain is selected; and -65 to 20dB when 0dB gain is selected.

Post Gain

Post Gain meter shows the input’s level after gain adjustments have been made. Meter range is from -30 to +20dB.

Post Processing

Post Processing meter indicates the level at the gating point after the signal has passed through input processing. It reflects the post-AGC signal. Meter range is from

-30 to +20dB.

Post Gating

Post Gating meter shows audio level after it has passed through the gating parameters. Meter range is from -30 to +20dB.

To select an output channel, click a blank area in the output pane. If you click on the output label, a secondary window will open allowing you to rename the output. The background color for the selected output channel will be light gray. The configurable properties of these outputs are defined in this section.

Mute

Mute mutes the output channel. The light on the button illuminates red when Mute is activated. Default is off (unmuted).

NOM

NOM (constant gain) maintains a constant output level as inputs routed to the output are gated on and off. The PSR1212 reduces the output gain (at the output) for mics based on the number of mics gated on and routed to that output. When using NOM over the expansion bus, only the first four audio channels (O, P, Q, and R) support

Optimizing output gain structure

How you adjust an output’s gain directly affects sound quality. The optimal output gain setting is one which is adjusted as high as possible above the noise floor without introducing clipping. Clipping can cause distortion which can damage amplifiers and loudspeakers.

To adjust the output level properly, place a signal on the output at the

maximum level it will generate. Adjust the output gain until the peak level of the input, as shown on the Level meter, just begins to enter the red (clipping) zone, then reduce the gain slightly until peaks no longer climb into the red zone. This setting will ensure that the PSR1212 maximizes the signal-to-noise ratio without clipping the signal.

Cmprs (compressor)

Cmprs opens the Compressor Setup window (see Figure 3.46). With the compressor you can change the gain transfer characteristics of the signal path and control the dynamics of a signal.

When the signal exceeds the threshold level, gain reduction occurs at the rate specified by the reduction ratio. The attack time determines how aggressively the compressor reacts to increases in level. The release time controls how aggressively the compressor reacts to reductions in level. Select the Enable Compressor check box to activate the compressor.

Group

Use the slider to assign this compressor to a compressor group. The default is

None

. When you assign a compressor to a compressor group—such as a group of three, configured for bass, midrange, and treble—the compressors will monitor each other. When one compressor channel compresses, all compressors in the group compress together. When configured properly, this results in a smooth audio response throughout the frequency range, with no bass, midrange, or treble dropouts. A given compressor group must be configured for a single PSR1212 unit; a group cannot use compressors from multiple PSR1212 units.

Figure 3.46. Compressor Setup window

Compressors and compressor groups can be

established only within the PSR1212 unit being configured, i.e., they cannot be configured from a single point across multiple units.

Attack Attack determines how quickly compression is enabled. It is calibrated in

milliseconds. The range is 0 to 100ms in .5ms steps. Default is 10ms.

Release Release determines how quickly compression is disabled. The range is

100ms to 2 seconds, in 5ms increments. Default is 500ms.

Input meter This peak meter shows the level of the signal as it enters the

compressor.

Compression meter This peak meter shows the instantaneous compression value

The frequency response and phase vs frequency of the total transfer function of all filters is displayed in the window. Each filter can be disabled without affecting the filter settings. All filters can also be disabled using a single command. By default, they are not enabled and the filter types are not defined. Below is a description of each feature in the window.

Active Filter

The Active Filter displays the filter that is applied to the processing channel.

Type

Select the filter type from the Type list.

Note that the configurable filter

parameters displayed depend on the selected filter type.

You can use these parameters to customize the filter, or use the mouse to click and drag the node on the graph to a location that reflects the changes you want to make.

You can continue to add filters to the graph, and track their relationships to each other to design a system with the sound characteristics necessary for good audio.

Phase

Phase plots the phase response of the frequency response of the selected filter.

Bypass

Bypass All bypasses all filters.

Add Filter

Add Filter adds a filter to the graph.

Remove Filter

This removes the selected filter from the graph.

Table View

Table View toggles between the graph view and the table view. The table view allows you to configure filters in a table format rather than on the graph, and provides an easy way to check filter status.

Processing Channels

The Processing Channels section allows you to display the graphs of various processing channels together, so you can view and easily modif y filter and equalizer settings throughout the frequency range. Click the respective letter to place a processor in the graph. Click the Active processor you want to modify; it appears in bold on the graph.

Technical Services Group ~ 1-800-283-5936 (USA) ~ 1-801-974-3760

Refer to the figure above. Note that as you create filters across several processing channels, you can observe their crossover points and general shape of the frequency response. In this case, several Linkwitz-Riley filters are being created across three processing channels to establish a balanced frequency response from low-frequency, midrange, and high-frequency transducers.

Delay

Click Delay to open the Delay configuration window. Delay calibrates the amount of signal delay introduced, based on the length (the distance between the source and audience) and temperature you enter.

For example, different speaker drivers within a speaker enclosure might be located different distances from the listening area because of design constraints within the box. You can set up to 500ms of delay.

Figure 3.48. Low/Mid/High Loudspeaker Driver configuration

If you don’t want delay added to the signal, select the Bypass Delay box.

The Calculated Delay reading reflects any changes you make in the

distance and temperature fields.

System Configuration ~ Processing

Technical Services Group ~ 1-800-283-5936 (USA) ~ 1-801-974-3760

Introducing an appropriate amount of delay to the forward-mounted driver(s) re-establishes the acoustical alignment necessary for proper sound imaging in a room. The same principle of introducing delay applies to separate speaker enclosures located various distances from the listening area.

Other types of delay to consider when establishing delay parameters are delays which occur naturally as a result of processing operations within the PSR1212. Propagation delay is an example. This delay is caused by operations such as the conversion of the signal between analog and digital formats.

When you are finished making changes in the Delay window, click Close to return to the Processor window.

Gain

Gain establishes the gain level for this channel. Select a level between -65 and 20dB. If you select any level below -60dB, the signal will be muted. The

Process

meter,

when enabled, shows the signal level when a signal is present.

Min/Max limits

Optimizing process gain structure

How you adjust the processing gain directly affects sound quality. The optimal gain setting is one which is adjusted as high as possible above the noise floor without introducing clipping. Clipping can cause distortion which can damage amplifiers and loudspeakers.

To adjust the processing gain level properly, place a signal on the output at the maximum level it will generate. Adjust the gain until the peak level of the input, as shown on the Process meter, just begins to enter the red (clipping) zone, then reduce the gain slightly until peaks no longer climb into the red zone. This setting will ensure that the PSR1212 maximizes the signal-to-noise ratio without clipping the signal.

CHAPTER 4: Advanced

Configuration

Presets

Overview

For many audio conferencing applications, a great deal of system flexibility is needed to meet the challenges presented by changing meeting or conference room requirements. These requirements might include changes in muting, audio sources, room orientation, or room combining. And ideally, these changes are made instantaneously—without interrupting or affecting any meetings in progress.

Using presets enables you to accommodate these changing room requirements quickly and efficiently. When you create a preset, you are essentially creating a single room configuration option. Presets can be programmed with a variety of routing, level, gating, delay, filter, and compression settings to meet specific application requirements. You can change every unit parameter or a select few depending on your room needs. PSR1212 presets are unique in the sense that they operate independently of other presets in the unit. When a preset is run, only the selected inputs/outputs are changed—all other settings in other presets remain unchanged and are not reset. This means you can change audio routing and configuration settings in a room without affecting settings in other rooms (such as gain). You can create up to 32 presets for the PSR1212.

Presets can be executed in a variety of different ways including the Execute Preset utility in G-Ware, the front panel controls of the PSR1212, RS-232 external control devices, RS-485 control devices (ClearOne Control Panel and XAP IR Remote), logic in/out, and contact closure. You can also create macros which can run multiple presets. These options give you tremendous flexibility when designing your installations and will be described in more detail in this chapter.

Creating Presets

Presets are created in G-Ware using the Preset mode. To switch to Preset Mode, click the Preset Mode button on the toolbar or the Preset Mode button on the Flow Screen. The Preset Mode window (see Figure 4.2) consists of the Preset Configuration Pane (left side of the window), the G-Ware menus and toolbar (although most options are not available because they do not apply to presets), and the Preset Matrix Screen. There is no Flow Screen in Preset Mode since all configurable settings can be accessed from the Matrix Screen.

Figure 4.1. Preset Mode toolbar button

Presets are used only within the local

PSR1212 unit. However, if a preset is part of a macro, it can be activated on a networked PSR1212 unit.

Matrix Screen

The Matrix Screen in the Preset Mode is very similar to the Matrix Screen in Configuration Mode. All Input, Output, and Processing windows can be accessed by clicking on their respective buttons. You can also create custom labels by clicking on the current labels.

The routing matrix is grayed out because no routing changes have been made. When you click on the number or letter of an input, the row becomes active and you can change the routing, gate status, and cross point attenuation. All parameters for the selected input will be saved in the preset including routing. Also, the parameters for any outputs with a cross point in the selected row will be saved. Input rows that are not selected remain gray, or masked, and will not be affected when the preset is run.

Preset Configuration pane

The Preset Configuration pane is used to create preset properties such as number, name, and description as well as create custom preset controls, assign the preset to a gating group, select macros, and configure virtual references.

Preset Selection. Use the Preset Selection list to assign a number to the preset

A typical use for Preset Mask Control Status B is a room combining application which uses automatic partitions with sensors or triggers which set the pin to high (H) when the partition is closed and to low (L) when the partition is open. For example, if pin 1 is connected to the first partition and Pin 3 is connected to the second partition, then the Preset Mask Control Status B settings shown in Figure 4.4 will activate the preset when the first partition is open and the second partition is closed.

Storage space

In a realistic preset configuration scenario, it is highly unlikely that you would reach the storage capacity of the unit. In the event that you exceed the preset storage space, G-Ware will alert you when you try to save the preset. You will be asked to reduce the number of cross point changes or the number of macros in the preset. As a general rule, if you make cross point changes to three-fourths of the matrix, you can establish a maximum of 128 nested macros for a given preset.

Technical Services Group ~ 1-800-283-5936 (USA) ~ 1-801-974-3760

Running presets

Presets can be run from G-Ware or the front panel controls on the PSR1212. You can also program external control devices (such as AMX or Crestron, ClearOne Control Panels, XAP IR Remote, and GPIO devices) or use macros to run presets. See Chapter 6: Control for more information on creating custom control.

To r un a preset using G-Ware

1. Select the

Execute Preset

button on the G-Ware toolbar.

2. Select the preset you want to execute from the

Preset

list.

3. Click Execute to run the preset and close the window.

To r un a preset using front panel control

1. From the System Menu, scroll to

Select Preset

and press

Enter

2. Scroll to the preset number you want to run and press

Enter

Running multiple presets simultaneously

To run multiple presets at the same time, you need to create macros (see page 61). A macro is a series of commands which can be executed from G-Ware or by using any external control device. Typically you will create a macro for each configuration or group of presets you want to run at the same time. This ability to r un multiple presets is critical in applications such as room combining. However, not only do you need to be able to run multiple presets simultaneously, you also need to be able to change presets without affecting other presets.

In order for this to happen, the system needs to know which presets have been run and shouldn’t be rer un and which ones are ready to r un. You supply the system with this information by setting the state (or flag) of the preset when creating the command line in the macro. The three options are:

0 = to set the state to off

1 = to execute the preset and set the state to on

2 = to execute the preset and set the state to off

Figure 4.8. Execute Preset window

Figure 4.7. Execute Preset

toolbar button

It is also possible to assign states to presets when

creating Remote Panel, serial, or GPIO control. However, unless you create macros, you will be able to run only one preset at a time.

✍

Technical Services Group ~ 1-800-283-5936 (USA) ~ 1-801-974-3760

Advanced Configuration ~ Presets

If a preset is flagged as “On,” nothing will happen when the preset is executed again because the system knows it has already been run. This prevents any manual adjustments that are made during the course of the meeting (gain, muting, etc.) from being lost.

Room combining example

In the room combining scenario depicted in Figure 4.10, there are four possible room configurations using six presets (P1–P6). In order to change configurations without disturbing meetings in progress, a macro must be created for each configuration that tells the system what to do with each of the six presets.

Figure 4.9. Assigning a state to a preset command in the Macro Editor

You can also create a macro to set all preset flags to 0 which ensures

all presets are ready to run again.

✍

Figure 4.10. Room combining diagram

Advanced Configuration ~ Presets

Technical Services Group ~ 1-800-283-5936 (USA) ~ 1-801-974-3760

The four macros (one for each configuration) are set up as follows:

When the room is in Configuration 1, running the Configuration 2 macro will change the presets to the following states:

• P1 does not change because the flag is already set (1)

• P2 and P3 clear their states (0) so they can be run

• P4 runs and sets its state to on (1) which prevents other presets from rerunning it

• P5 and P6 clear their states (0) so they can be run

When the room is in Configuration 3, running the Configuration 1 macro will change the presets to the following states:

• P1 and P2 run and set their state to on (1) which prevents other presets from rerunning them

• P3 does not change because the flag is already set (1)

• P4, P5, and P6 clear their states (0) so they can be run

For more detailed information on creating macros, see the Macros section on the next page.

Technical Services Group ~ 1-800-283-5936 (USA) ~ 1-801-974-3760

Advanced Configuration ~ Macros

A macro is a series of commands which can be run from G-Ware, the front panel controls, or by using any external control device. Macros streamline the operation of the PSR1212, allowing you to make quick configuration changes and, as previously discussed, making it possible to execute multiple presets simultaneously (see pages 58–60). Macros can also contain commands that are executed on other XAP units. See pages 95–96 for a list of commands which can be used in macros.

The PSR1212 is designed to support up to 255 macros, with an average of 150 command lines each. In the unlikely event that you exceed G-Ware’s capacity, you will be notified with a warning that indicates the command line at which memory is exceeded.

Creating macros

There are two ways to create macros in G-Ware: the Macro Recorder, which records your onscreen selections, and the Macro Editor, which allows you to directly create command lines. The Macro Editor is also used to edit macros created using the Macro Recorder.

To create a macro using Macro Recorder

1. Click the Macro Recorder button on the G-Ware toolbar. The Macro Record

window opens and the mode is changed to Macro on the status bar.

2. Select the macro number from the Macro to Record list, then click Start.

3. Make any routing and input/output configuration changes (such as gain

adjustments, mute, etc.) to be included in the macro. Make these changes

the same way you made changes in Configuration mode (see Chapter 3:

System Configuration for more information).

4. Click Stop in the Macro Record window in the upper right-hand corner of

the screen. This stops the macro recording and opens the Macro Editor

window. See page 63 for editing instructions.

Signal Generator

The Signal Generator window allows you to generate test audio signals to check signal paths, gain settings, etc. The Signal Generator can generate pink noise, white noise, and tone.

• Pink Noise. Pink noise is an audio test signal containing all the frequencies in a given audio spectrum, with equal energy in each octave. Pink Noise is the default signal.

• White Noise. White noise is an audio test signal which is distributed evenly throughout a given frequency range.

• Tone. Selecting Tone activates the tone configuration portion of the window. The tone is a sine wave with less than .03% distortion.

The test signals created by the signal generator are assigned to a particular input; this allows you to verify the operation of the processor settings you have selected.

To use pink or white noise

1. Select the PSR1212 Unit and Input Channel you want to use.

2. Use the Amplitude control to select the amplitude (volume) of the signal you want to use. The amplitude range is from -60 to +20dB. Default is 0dB.

3. Select Pink (default) or White.

4 Click Signal On to generate the noise signal on the selected input. Click

Signal On again to terminate the noise signal.

Remote Modem Access

You can access the unit remotely through a modem connected to the serial port. To enable this feature, configure the port for modem mode.

When in modem mode, the serial port will send an initialization string to the

modem upon entering the mode or upon power-up of the unit. You program the initialization string in Site Properties window in G-Ware. Typical configurations you set with the initialization string include setting a fixed baud rate for the unit and setting up auto-answer parameters.

You must enter a password before you can control the system this way. The

default password is blank (a carriage return). You can change it to any combination of letters and/or numbers up to 12 characters. It is not case-sensitive.

When you establish a valid serial connection with the unit in modem mode,

the unit will wait for a carriage return. When you have entered a carriage retur n, the system will prompt you to enter the password. If there is no activity for five minutes on the serial port while in modem mode, the unit will re-prompt for the password.

Serial commands

Serial commands can be passed through the PSR1212 RS-232 port using Hyper Ter minal, touch panels, or other compatible remote control devices. To learn more about serial commands, see Appendix E.

RS-232 Port

The modem password is created in the Unit

Properties window (see page 26) or by using the MPASS serial command (see page 114).

Control/Status connectors

The Control/Status connections are provided on two DB-25 connectors. These connectors are labeled Control/Status A and Control/Status B and contain different types of pins. The inputs on these connectors are internally pulled high and are activated by connecting the pin to ground. The outputs are open collectors, which are open when inactive and grounded when active. This allows the PSR1212 to control and be controlled by a wide variety of external devices, including relays, lamps, switches, and other equipment. Control pins on Control/Status A are momentary while control pins on Control/Status B are latching.

Figure C.3. Wiring the Control Panels

The Volume Control Panel and Select Control Panel connect to either the Remote Panel A or B connector of the PSR1212, XAP 800, or XAP 400 and works by triggering the execution of programmed commands from the XAP/PSR unit. Each button on the control panel is programmable to execute a single command or a series of commands. Button function is programmed using G-Ware software (see the XAP or PSR user manual). Each Control Panel fits inside a standard electrical wall box and must be installed according to local electrical codes.

Connecting the Control Panel

1. Ensure you received a facia plate; a Control Panel assembly with mounting bracket and two RS-485 Phoenix four-pin connectors; two connector terminator blocks; a faceplate; two flat HD screws; two pan-head screws; and an electrical wall box (shown in Figures C.5 and C.6). If any parts are missing, please contact ClearOne.

2. Using DIP switches 1–4, assign a unique ID to the Control Panel.

Refer to Figure C.2 for proper DIP switch settings. If you set an invalid address, all LEDs on the Control Panel will illuminate.

3. Set DIP switch 8 to the on position if you are using just one Control Panel. If you have more than one Control Panel daisy-chained to the same Remote Panel connector, set

only

the

last

Control Panel’s DIP switch 8 to on. Switches 5-7 are

nonfunctional.

4. Turn off the XAP/PSR unit (unplug the unit).

5. Wire each end of a Cat. 5 cable to a connector terminator block. Use one twisted wire pair for the center - and + connections (pins 2 and 3) and the other twisted pair for the ground and +15V connections (pins 1 and 4). Failure to correctly wire the connector can result in damage to the unit.

6. Connect one connector ter minator block to the Remote Panel on the XAP/PSR unit. Route the other end of the cable through the back of the electrical wall box and connect the terminator block to the Control Panel.

7. To use a second Control Panel, connect it to the unused Remote Panel connector on the XAP/PSR unit or the unused connector on the first Control Panel. You can daisy-chain up to six Control Panels to each Remote Panel connector. Total cable run depends on the number of Control Panels used. The distance information in the table at left is based on Cat. 5 cable with a nominal resistance of 27Ω per 1,000 feet (305 meters). All distances refer to total cable runs from a single Remote Panel connector. For information about extending beyond 800 feet (244 meters) total with six Control Panels, call Technical Support at 1-800-283-5936.

8. As shown in Figures C.5 and C.6, use the supplied pan-head screws to install the Control Panel PCB assembly to the electrical wall box.

9. To install the facia plate, position it over the conductive rubber switch pads on the PCB assembly, as shown in Figures C.5 and C.6.

10. Mount the faceplate over the rubber switch pads, using the two flat HD screws.

Appendices ~ Appendix E: Serial Commands

The PSR1212 accepts serial commands through the serial port or the expansion bus. The commands in this manual pertain only to the PSR1212. RS-232 serial port protocol is 9,600, 19,200, 38,400 (default), or 57,600 baud; 8 bits, 1 stop bit, no parity.

Conventions

The following typographic conventions are used in this document to describe the different serial commands. Use the Command structure section and the examples as a guide when creating your serial commands.

Convention Description

<X> Parameters enclosed in < > indicate a mandatory parameter. [X] Parameters enclosed in [ ] indicate an optional parameter. 1-8 Parameters separated by a - indicate a range between the values. 4,7,9 Parameters separated by a , indicate a list of available values.

EREF

Words in uppercase bold indicate command text.

DEVICE Indicates the device type and device number on the expansion bus network. It is composed of a

device type character and a device number. The device type for the PSR1212 is always 4 and the device ID will always be 0–7, or * (to select all PSR units).

Command structure

Commands can be either UPPER CASE or lower case. Also, extra spaces or tabs between arguments in text commands are allowed. Return values are always in upper case. In order for a command to be recognized by the serial port, the command must be terminated by a carriage return.

The structure of serial commands is as follows: #DEVICE

COMMAND

[X] [X]

# indicates the start of a command line DEVICE represents the device type and device number

COMMAND

is the command text

[X] [X] represents any additional options in the order that they appear in the command descriptions that

Example

A command to disable automatic gain control for Mic 2 on a PSR1212 device “0” will have the command line: #40 AGC 2 M 0. In this command line, 4=PSR1212, 0=unit 0, AGC=command, 2=channel, M=Mic Input group, 0=off state. If a command calls for a “null” value, leave a blank in the command line. For example, “#40 AGC 2 M” will return the current AGC state of Mic 2 on device 50.

Command responses will have a carriage return line feed. Example: #40 AGC 2 M O car riage retur n line feed.

Appendices ~ Appendix E: Serial Commands

Groups and channels

If a channel has an alpha value of “*”, the command is to be applied to all channels. For example, a group value of M and a channel value of * would mean that the command is to be applied to all channels of group M (mic inputs). The following table show the alpha representations for the different groups and the channels that are available for each product.
