indication of improper installation. Check location and wiring of all

infrared receivers.
The Main Preset (A~D) and Zone Preset (E~H) LEDs indicate
which preset is currently active for each output. A preset contains
all of the source and level settings for an output, which are stored
in non-volatile memory for future recall. Presets can be used to
simply change inputs and levels, or to completely re-configure
system operation. When the SPM522D is in 'Room-Combining
Mode', only one Preset LED will be lit (Main or Zone). The
Channel (1~5) LEDs indicate which stereo input channel is
selected for each output. Each channel selection may include its
own customized tone and balance settings. The Mic (1 & 2) LEDs
indicate which mic/line inputs are assigned to each output. When
a mic/line input is set for 'gated' operation, the associated LEDs
will light only when the input is active (gate open). The Main and

only reduces the level that output will return to when it is un-muted.
However, increasing the level setting of a muted output will
automatically un-mute that output. Similar external Remote
Display Panels are optional (see Remote Controls on pg. 5).

SPM 522D

Infrared Transmitter

(Biamp #909-0064-00)

The type and quantity of remote controls is optional for the SPM522D. Remote control affects source selections, preset selection, mic/line
input levels, and main/zone output levels. Remote controls may be added at any time, and do not require the SPM522D to be modified,
opened, or removed from a rack. There are five types of remote controls available: The Infrared Transmitter, the Infrared Receiver, the
Wall-Mount Panel, the Remote Interface Kit, and the Remote Display Panel. The SPM522D may also be controlled via computer and
certain third-party controllers.

Remote controls come with complete instructions.

NOTE:

Infrared Receiver

(Biamp #909-0030-00): The Receiver consists of a black plastic box, containing an infrared
photo detector, an LED indicator, and five screw terminals. To install Receiver, first take off front cover by
removing four screws. Mount Receiver to wall or other surface, using two screw holes on back cover (screws
not included). Receiver should not be mounted in direct sunlight, or pointed directly at fluorescent lighting. For
best results, there should be an unobstructed line-of-sight from Transmitter to Receiver. The Receiver may be
wired up to 2000 feet from the SPM522D, using 2-conductor shielded cable (not included). Route cable through
access hole on bottom of Receiver. Three screw terminals inside the Receiver ("GND", "IR2", & "IR3")
correspond to "Remote" terminals on rear of SPM522D. Connect cable shield to "GND" terminals at each end.
Use conductors to connect "IR2" to "IR2" & "IR3" to "IR3". Replace Receiver front cover. The LED indicator
inside Receiver lights when infrared information is detected.

The Infrared Receiver also includes two

NOTE:

'Remote Translator' terminals ("GND" & "XLATE"), which allow remote control of the SPM522D via third-party
'serial' controllers. Complete instructions are included with the Infrared Receiver.

InfraRed Transmitter

(Biamp #909-0064-00): The Transmitter is a hand-held controller, which transmits
infrared codes unique to Biamp. Therefore, the Transmitter should not affect any other infrared controlled
equipment (such as TVs or VCRs). Likewise, other infrared controllers will not provide proper control of Biamp
equipment. The Transmitter requires two AAA batteries, which are included with the unit (user installed). The
Transmitter has twenty-eight buttons. Main (1~5) buttons select which stereo input channel (plus tone & balance
settings) is routed to the Main output. Main (A~D) buttons select the desired preset for the Main output. Zone
(1~5) buttons select which stereo input channel (plus tone & balance settings) is routed to the Zone output.
Zone (E~H) buttons select the desired preset for the Zone output. From the factory, button D/5 (Main) and H/5
(Zone) select stereo input channel #5 to be routed to the respective outputs. However, during Configuration
each of these buttons may be re-defined to instead recall the respective D & H presets (see Configuration on pg.

9). During Setup Mode the Main (A~D) and Zone (E~H) buttons are used to store the respective presets (see
Setup on pg. 6). The MUTE buttons (Mic 1, Mic 2, Zone, & Main) turn off the respective mic/line input or stereo
output signals. The Vol

& Vol ▼ buttons (Mic 1, Mic 2, Zone, & Main) adjust the level setting of the respective

▲

mic/line input or stereo output signals. Decreasing the level setting of a muted input/output only reduces the
level that input/output will return to when it is un-muted. However, increasing the level setting of a muted
input/output automatically un-mutes that input/output. When a mic/line input is set for 'gated' operation, level
settings can be adjusted only when the input is active (gate open). The way in which an SPM522D responds to
remote control buttons may be completely re-defined during Configuration (see Configuration on pg. 9) For best
results, there should be an unobstructed line-of-sight from Transmitter to receiver. The Transmitter will operate
up to 30 feet from a receiver. In addition to the Infrared Receiver described above, receivers are also included
on the SPM522D, the Wall-Mount, and the Remote Display Panel.

Wall-Mount

(Biamp #909-0074-00): The Wall-Mount is a "hard-wired" control, which is powered
by the SPM522D. There are no batteries to wear out, and it is not easily lost or stolen. The wall­mount may be wired up to 2000 feet from the SPM522D, using 2-conductor shielded cable (not
included). To install Wall-Mount, first remove mounting box from front panel. Route cable
through "knock-out" hole on rear of mounting box. Install mounting box in wall or panel. Three
screw terminals on circuit board ("GND", "IR2", & "IR3") correspond to "Remote" terminals on
rear panel of SPM522D. Connect cable shield to "GND" terminals at each end. Use conductors
to connect "IR2" to "IR2" & "IR3" to "IR3". Install front panel on mounting box. The Wall-Mount
has twenty-eight buttons. Main (1~5) buttons select which stereo input channel (plus tone &
balance settings) is routed to the Main output. Main (A~D) buttons select the desired preset for
the Main output. Zone (1~5) buttons select which stereo input channel (plus tone & balance
settings) is routed to the Zone output. Zone (E~H) buttons select the desired preset for the Zone
output. From the factory, button D/5 (Main) and H/5 (Zone) select stereo input channel #5 to be
routed to the respective outputs. However, during Configuration each of these buttons may be
re-defined to instead recall the respective presets D & H (see Configuration on pg. 9). During
Setup Mode the Main (A~D) and Zone (E~H) buttons are used to store the respective presets
(see Setup on pg. 6). The MUTE buttons (Mic 1, Mic 2, Zone, & Main) turn off the respective
mic/line input or stereo output signals. The Vol

remote control buttons may be completely re-defined during Configuration (see Configuration on
pg. 9) The green LED will light when the Wall-Mount receives power from the SPM522D. The
red LED will flash whenever the Wall-Mount is transmitting information. The Wall-Mount
includes an infrared detector, which allows it to operate as an Infrared Receiver, as well. The
infrared detector may be disabled via an internal circuit board jumper strap (labelled "IR RECV").

Remote Interface Kit

(Biamp #909-0041-00): The Remote Interface Kit allows the user to create a customized control panel, using his
own switches, enclosure, and panel. It can provide up to 40 buttons (12 more than standard remote controls), which are supported by the
SPM522D. The Remote Interface Kit is a tested circuit board assembly, which includes two wiring harnesses. The circuit board connects
to the SPM522D in exactly the same way the Infrared Receiver or Wall-Mount does, using 2-conductor shielded cable (not included ), and
may be wired up to 2000 feet from the SPM522D. The circuit board is 2.27"W by 2.65"H, with four mounting holes (2" centers) an d #6
mounting hardware provided.

SETUP

Setup Mode allows presets to be defined and stored in non-volatile memory, without the need to use the PC Control Software for
Configuration via computer. Setup Mode may also be used to return the SPM522D to the factory default settings.

To enter Setup Mode: While power is on, press and hold the front panel Setup button for 5 seconds (until the currently lit Front Panel
Display LEDs begin flashing). The Front Panel Display LEDs are the only indication that the SPM522D is in Setup Mode, and they will
continue flashing as long as Setup Mode is active.

During Setup Mode: The Remote Control buttons which were assigned to recall presets are temporarily re-defined to store those presets.
All other Remote Control buttons will function normally. This allows a preset to be created by first adjusting the various source and level
settings for the respective output, then pressing the appropriate 'store' button.

Example: From the factory, six buttons are assigned to recall presets (Main Preset A~C and Zone Preset E~G). During Setup Mode,
these six buttons would become their own respective store buttons. Once the desired stereo input channel, mic/line input levels, and Main
output level settings were made, pressing the Main Preset A button would store those settings. After exiting Setup Mode, those same
settings could easily be recalled from the non-volatile memory by simply pressing the Main Preset A button.

To exit Setup Mode: Press the front panel Setup button momentarily. The Front Panel Display LEDs will quit flashing and the SPM522D
will immediately exit Setup Mode. The SPM522D will also

NOTE: Configuration may be used to assign the Main Preset D and Zone Preset H buttons to recall presets (instead of selecting stereo
input channel #5). Configuration may also be used to disable the Setup Mode functions described above. See Configuration on pg. 7.

NOTE: Remote Display Panel LEDs will not flash during Setup Mode.

automatically

exit Setup Mode after 1 minute of inactivity (no button entries).

To return to factory default settings: While power is off, press and hold the front panel Setup button. While holding the Setup button, turn
power on. Continue holding the Setup button for 2 seconds (until the Error LED flashes once). The SPM522D will begin setting all 'button
definitions' to their factory defaults (see Configuration on pg. 9). If the Setup button is held another 7 seconds (until the Error LED flashes
twice), the SPM522D will begin setting all "preset mixes' to their factory defaults (see Configuration on pg. 7). If the Setup button is held
another 2 seconds (until the Error LED flashes three times), the SPM522D will begin setting all 'Configuration Options' to their factory
defaults (see Configuration on pgs. 11~14). Whenever the Setup button is released the SPM522D will return to normal operation. The
Setup button may be released at any time, depending upon which factory defaults are desired.

forward and the top panel facing up. Remove the top panel (eight screws along the sides and rear; one screw centered behind the front
panel). The following modifications occur on the lower circuit board (see diagrams below). These modifications require no soldering.

Internal Infrared Receiver Bypass:

A bank of four DIP switches is located toward the right­center of the circuit board. The far right switch ('IR RECV') is used to activate or bypass the
Internal Infrared Receiver. From the factory, the Internal Infrared Receiver is activated, with the
switch toward the front panel. To bypass the Internal Infrared Receiver, push the switch back,
toward the rear panel.

Channel 5 Internal 30dB Pad:

Two jumper straps ('P501' & 'P502') are located toward the rear­center of the circuit board (underneath the upper circuit board). These jumper straps are used to
activate or bypass a 30dB pad at the Channel 5 input. The 30dB pad allows Channel 5 to accept
greater input signal levels, such as those produced by a 70.7V 'constant voltage' distributed
speaker system. From the factory, the 30dB pad is bypassed, with both jumper straps toward
the left. To activate the 30dB pad, move both jumper straps over one pin, toward the right.

TONE and BALANCE SCREENS

Tone and Balance screens are available for all five Stereo Line Inputs. They are accessed through the Configure SPM522D drop-down
menu (or by right-clicking on the Mix screen). Also, double-clicking on a Channel (1~5), within the Mix screen, will simutaneously select
that channel and open its specific Tone and Balance screen. Tone and Balance screens allow each of the Stereo Line Input channels to
have its own Treble, Bass, and Balance settings for the Main & Zone Outputs independently. Tone and Balance settings for each Stereo
Line Input are stored in non-volatile memory, and are automatically recalled whenever that Stereo Line Input is selected for the associated
output. Tone and Balance screens are divided into two sections. The left section affects the Main Output and the right sectio n affects the

CONFIGURATION

BUTTON DEFINITION SCREEN

The Button Definition screen is used to assign specific ‘actions’ to remote control buttons. ADVANTAGE® infrared & wall-mount remote
controls have twenty-eight buttons. However, the SPM522D supports twelve additional buttons, which are only available when using
Remote Interface Kit or RS-232 control (see Remote Controls on pg. 5 & Computer Control on pg. 15). From the factory, the SPM522D is
programmed as follows: Buttons 1~12 provide volume up, volume down, & mute actions for Mic 1, Mic 2, Zone Output, & Main Output;
Buttons 13~28 provide preset & channel select actions for Zone Output & Main Output; Buttons 29~40 provide no defined actions.
However, using the Button Definition screen, each button may be assigned various, different actions (button definition). There are eight
types of actions available for both the Main & Zone Outputs. Each action type
have one of each type of action assigned to it, thereby performing multiple functions. A button may also be assigned no actions at all,
thereby making that button inoperable. This is an effective way of limiting user access to certain settings or functions. Left-clicking a

COMPUTER CONTROL

The SPM522D has an RS-232 compatible serial interface, which allows it to be controlled by a computer (see Rear Panel Features on
page 3). In addition to the PC Control Software, the SPM522D offers two other methods of computer control.

Control Button Emulation:

This method allows the computer to emulate the operation of the infrared transmitter or wall-mount control
panel. Using this method, the computer outputs ASCII characters, which are equivalent to the commands generated by the standard
control buttons. The SPM522D is unable to tell whether these commands come from the computer or from a standard control. However,
Control Button Emulation allows the computer to utilize up to forty button definitions (unlike standard controls, which have only twenty-eight
buttons). When using up to

four SPM522Ds in a system, Control Button Emulation also allows the computer to designate which device or

devices should react to each control button command.

Advanced Computer Control:

This method provides advanced commands, which allow the computer to retrieve or edit preset mixes,
retrieve or edit control button definitions, perform preset & volume actions, and a variety of other functions. The computer may also
emulate control buttons. Using this method, the computer may designate up to

eight devices, and may create unlimited preset mixes and

control button definitions. The computer may also provide "real-time" display of various settings.
This manual only describes the Control Button Emulation method of computer control. For complete details about using the SPM522D with

a computer, including Advanced Computer Control, contact Biamp Systems for manual "Computer Control of SPM522D".
Each control button on the infrared transmitter or the wall-mount control panel corresponds to one character in the standard ASCII

character set. The character equivalents are summarized in the following table. This table includes all forty of the possible buttons, their
button numbers, their ASCII code equivalents, and their factory default button definitions (functions).

button 14 O Recall Zone P reset F button 28 ] Sel ect Channel 4 Main

When a control button is first pressed, the SPM522D receives the character which corresponds to that button. If the control bu tton is
pressed longer than 110 milliseconds, the SPM522D receives a "repeat code", indicating the control button is still being pressed. The
SPM522D continues to receive the repeat code (approximately nine times per second) until the control button is released. The A SCII
character which corresponds to the repeat code is @ (the "commercial at" sign).

The "receive data" (RxD) signal at the SPM522D Serial Port is combined with signals from any standard controls, before being se nt to the
main microprocessor. The computer can initiate any functions or actions that a standard control can, by simply transmitting the equivalent
control button ASCII character. When interfacing the SPM522D to a computer, the computer must be aware that the SPM522D will "echo"
all characters it receives (both from computer and standard controls) via the Serial Port 'transmit data' (TXD) signal.

Up to four SPM522Ds may be connected together, and addressed individually, when using Control Button Emulation. When multiple units
are used, each unit should be assigned a unique "Device Number" (see Configuration on pg. 11). Normally, all of the SPM522Ds would
react to control button commands. However, the computer can send commands to specific units, by preceding each command with a
"device select prefix" character (see following table). Only those SPM522Ds whose Device Numbers are specified will respond to the
command which follows. Those specific devices will also react to any repeat codes which immediately follow the command. If a command
is not immediately preceded by a device select prefix character, then all SPM522Ds in the system will react to that command.

COMPUTER CONTROL

Serial Interface Electrical Connections & Cabling:

The 9-pin Subminiature D (male) connector on the SPM522D rear panel provides
the RS-232 compatible serial interface signals used for computer control. The SPM522D transmits serial data on pin 3 (TxD) and receives
serial data on pin 2 (RxD). The serial interface ground is on Pin 5. The DTR & RTS signals are connected to the +12 Volt power supply
(each through its own resistor) and are always asserted when the SPM522D power is on. Most IBM compatible PCs use either 25-pin or 9­pin (male) connectors for their serial ports. The following table summarizes the pin assignments for the SPM522D serial interface, and for
the standard IBM compatible 9-pin and 25-pin serial ports.

SIGNAL NAME DIRECTION SPM522D 9-P IN IBM-PC 9-PIN IBM-PC 25-PIN

CD (carrier detect) input n/a pin 1 pin 8
RxD (receive data) input pin 2 pin 2 pin 3
TxD (transmit data) output pin 3 pin 3 pin 2
DTR (data terminal ready) output pin 4 pin 4 pin 20
signal ground n/a pin 5 pin 5 pin 7
DSR (data set ready) input n/a pin 6 pin 6
RTS (request to send) output pin 7 pin 7 pin 4
CTS (clear to send) input n/a pin 8 pin 5
RI (ring indicator) input n/a pin 9 pin 22

The SPM522D only requires receive data (pin 2), transmit data (pin 3), and signal ground (pin 5) to be connected for successful data
communications. However, the PC may require that signals be present on the data set ready, clear to send, or carrier detect inputs, as
well as the receive data, transmit data, and signal ground pins. The diagrams on the following page show cables for interfacing to a PC
with either a 9-pin or a 25-pin serial port connector. In most cases, one or the other of these cables will work. However, success or failure
depends entirely on the actual computer hardware and software being used. When trying to solve an interfacing problem, the most
important thing to remember is that an output of one device should connect to one or more inputs of the other device, and that two outputs
should never be connected together. Also, keep in mind that the RS-232 specification calls for the cable length to be no great er than 50
feet (although it is not unusual to be able to operate over distances of 150 to 250 feet), and the connectors must be of the appropriate
gender (male or female) to mate properly. For best results, a shielded cable should be used, with the shield connected to signal ground.
Since the SPM522D serial interface ground is also tied (indirectly) to the analog signal ground, undesirable ground loops may occur when
the SPM522D is connected to a PC (if the system grounding is not carefully designed). For best performance, the PC ground and the
chassis ground of the SPM522D should be at the same potential, and the PC should get AC power from the same source as the SPM522D
(and any other audio equipment which is connected to the SPM522D).

Serial Interface Data Communications Parameters:

The SPM522D communicates through the serial interface at a rate of 9600 bits per
second, with 8 data bits, 1 stop bit, and no parity. The SPM522D utilizes a subset of the standard 7-bit ASCII character set. The eighth
data bit of each character (the most significant bit) should always be 0. The computer should not echo the characters it receives. The
computer should not be set for either hardware (DTR) or software (XON/XOFF) flow control. The baud rate may be changed to 2400 bits
per second by means of an internal DIP switch labelled ‘Opt. W’ (for access instructions and switch diagram see Options on pg. 6). The
‘Opt. W’ DIP switch is located on the right-center of the lower circuit board, adjacent to the microprocessor (U2). To select 2400 baud rate:

1) Disconnect power from the SPM522D. 2) Remove top panel. 3) Move ‘Opt. W’ DIP switch towards the rear panel, to the ‘off’ position.
