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.

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.

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.

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.

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

1.

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.

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

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.

15

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

16

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.

CHAPTER 3: System

Configuration

G-Ware Requirements

ClearOne’s G-Ware software provides an easy interface for configuring and
controlling your PSR1212. While some configuration can be done using the front
panel LCD menus, G-Ware is required to complete the custom configuration of your
audio conferencing system. If you are using the default settings, no configuration is
necessary.

Creating Floppy Disk Copies

Depending upon the computer equipment you have available, you might need to
install G-Ware software from floppy disks rather than the included CD. To do this, a
Disk Copy program is provided in G-Ware that allows you to transfer G-Ware to
floppy disks. You will need a PC with a CD-ROM drive to make the transfer. You can
access the Disk Copy program in the following ways:

• After installing G-Ware, go to the Windows®Start menu, select Programs,
then ClearOne G-Ware, then Create Install Floppy Disks.

– or –

• In the G-Ware section of the Audio Video Product CD, click on Install Now.
Choose Create Installation Floppy Disks from the G-Ware setup menu.

To install G-Ware

1. Boot the PC to the Windows operating system. Ensure that all other
programs or applications are closed. Insert the Audio and Video Products
CD into the CD-ROM drive.

If the Autorun feature is enabled on the PC, the ClearOne Welcome window
opens. Click the Software tab and select G-Ware.

If the Autorun window does not open, open the Windows Start menu and
choose Run. Type “<drive>:\\clearone.exe” where <drive> is the letter of
the CD-ROM drive (e.g., D:\\clearone.exe).

2. At the G-Ware window, click Install Now near the bottom of the window.

3. Select Install G-Ware from the setup menu. The InstallShield Wizard opens,
and guides you through the Welcome and License Agreement windows. At
the Choose Destination Location window, choose the directory where G-Ware
will be installed. We recommend that you use the default directory.

4. Click Next or Yes to move to proceed through the windows that follow or
No or Cancel to end the installation process.

5. Follow the onscreen instructions. You must restart your computer once
installation is complete.

The G-Ware Program Folder is now added to your Start menu. You can start
G-Ware through the Start menu or by double-clicking the desktop icon.

Site Setup

Creating a new site

New site files are created through the Site Properties window in G-Ware. A site file
contains all information about a particular installation including all unit settings and
properties. It also provides G-Ware with the necessary information to communicate
with the site hardware using your PC. Open G-Ware by double clicking the desktop
icon or by selecting G-Ware from the Start menu.

To create a new site

1. Open the Site Properties window by selecting New Site from the File menu
or by clicking the New Site button on the toolbar.

2. In the Site tab, enter the site name, author, company, location, room, and
description, using the Tab key or mouse to select each field.

3. Click the Comm tab. Select the COM port, baud rate, and flow control you
want to use. ClearOne recommends that you leave Flow Control set to
Hardware. The Software setting is not supported by PSR/XAP units and is
typically used with modems.

4. If you plan to use a modem, select Use Modem and enter the phone number,
initialization string, and reset string.

5. Click the Security tab. Enter the site password in the Site Password box.
Click File Access Password to create a password for the Site File.

Whenever a mouse click is
indicated in this manual, it
refers to the left mouse

button unless otherwise stated.

Adding a PSR1212

You can add a PSR1212(s) to your site file by connecting to your site and using
G-Ware to automatically create icons for the detected units. Or, you can work offline
and manually add the unit(s) to the site file and connect to the site at a later time.
To open an existing site file, click the Open Site File button or select Open Site from
the File menu.

To auto-detect units

1. Click the Connect button on the G-Ware toolbar or select Connect from the
Connect Menu.

2. Choose Sync to Unit(s). G-Ware will automatically create icons for the new
units it detects on the network and place them in the Site pane. See Figure

3.11.

Note: When connecting to your site, you can choose to sync to Unit(s) or
Document. If you sync to the Unit(s), you will overwrite your G-Ware site file
with the current settings of the unit(s). If you sync to the Document, you will
overwrite the settings in your units with the settings you have saved in the site
file. Choosing to sync to Document will also create icons for any new units.

To manually add units

1. If you are working offline, click the Add button on the G-Ware toolbar. This
opens the Add Unit window.

2. Select the PSR1212 icon and click Add.
