FRONT PANEL FEATURES
Channel Gate Indicators: These red LEDs normally indicate
when Channels 1~8 are active to Main Out (‘on’ or ‘auto’ gating).
NOTE: When a channel is assigned as ‘off’ to Main Out, but is
assigned as ‘auto’ to Aux Out, this indicator will light when the
channel is active (gated on) to Aux Out (see Setup on pg. 5).
Power Switch & On Indicator: When the Power Switch is
depressed, the adjacent red LED will light indicating power to the
mixer is On. Release the Power Switch to turn power off. When
power is turned off, all ‘current mix’ settings (levels, assignments,
etc.) will be stored in non-volatile memory and recalled when
power is turned back on. NOTE: During setup the VRAM may
instead be set to recall a special preset whenever power is turned
on (see Setup on pg. 9).
REAR PANEL FEATURES
AC Power Cord: The power transformer provides 27 Volts AC to
the VRAM, and is detachable via a 5-pin DIN connector. The
VRAM has two internal ‘self-resetting’ fuses (there are no user
serviceable parts inside the unit). If the internal fuses blow, they
will attempt to re-set after a short period. However, this may be an
indication that the VRAM requires service.
Serial Port: This 9-pin Sub-D (male) connector provides an RS-
232 Serial Port for remote control via computer or third-party
controllers (see RS-232 Control on pg. 14). The Serial Port has
the following pin assignments (left-to-right & top-to-bottom): Pin 1)
not used; Pin 2) Receive Data (RxD) input; Pin 3) Transmit
Data (TxD) output; Pin 4) Data Terminal Ready (DTR) output;
Pin 5) Ground; Pin 6) not used; Pin 7) Request To Send (RTS)
output; Pin 8) not used; Pin 9) not used. PC Control Software
and a serial cable are provided for programming via Windows
®
95
(see Setup on pg. 4). NOTE: The Serial Port can also transmit
commands received via the Logic Inputs (see Setup on pg. 8).
Link Port: This 9-pin Sub-D (female) connector provides a Link
Port for RS-232 control of multiple ADVANTAGE
®
products (see
RS-232 Control on pg. 14). The Link Port of one device simply
connects to the Serial Port of the next device (and so forth). Link
cables are available as an option (Biamp #909-0057-00). NOTE:
All but the final device in a system should have the Link Switch
pressed in (see below). The Link Port has the following pin
assignments (right-to-left & top-to-bottom): Pin 1) not used; Pin
2) Transmit Data (TxD) output; Pin 3) Receive Data (RxD) input;
Pin 4) not used; Pin 5) Ground; Pin 6) not used; Pin 7) not
used; Pin 8) not used; Pin 9) not used. NOTE: The Link Port
will also transmit commands received via the Logic Inputs (see
Setup on pg. 8).
Link Switch: The Link Switch is used when connecting multiple
devices in a ‘Link Port to Serial Port’ configuration (see Link Port
above). From the factory, the Link Switch is released (out). When
connecting multiple devices, the Link Switch must be depressed
(in) on all devices except
the final device in the system (the device
with no Link Port connection).
