Error: This red LED indicates unusable information is being
received via remote control (see Remote on pg. 3). If an error in
transmission/reception of a remote control command occurs, the
Error indicator will flash.

Remote: This red LED indicates information is being received
via remote control (see Remote & Logic Inputs on pg. 3). If the
Remote and Error indicators flash simultaneously, this may be
an indication of improper installation. Check the location and
wiring of all remote controls.

AC Power Cord: The power transformer provides 27 Volts AC
to the DRI, and is detachable via a 5-pin DIN connector. The
DRI has two internal ‘self-resetting’ fuses (there are no user
servicable 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 DRI requires service.

Link Port: This 9-pin Sub-D (female) connector provides a Link
Port for RS-232 control of multiple ADVANTAGE
RS-232 Control on pg. 15). 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 its ‘last’
switch down (see Baud Rate)

Control Voltage Outputs: This 15-pin Sub-D (female)
connector provides up to twelve 0~+10 Volt DC control voltages,
and up to two logic outputs (see Control Voltage Outputs on pg.

4). Control Voltage Outputs have the following pin assignments
(right-to-left & top-to-bottom): Pins 1 ~11) Control Voltage
Outputs 1~11; Pin 12) not used; Pin 13) Logic Output 1; Pin

14) Logic Output 2; Pin 15) Ground. When controlling an

DLA93, the DRI Control Voltage Outputs are
connected directly to the DLA93 Remote Control connector,
using the ‘inter-connect’ cable provided with the DRI. The DRI
controls the following DLA93 functions: Channel 1~8 level; Aux
Input level; Main Output level; Aux 1 Output level;
Master/Slave switching; and Auto/Manual switching. When

Link Port will also transmit commands which are received via
Remote & Logic Inputs (see Setup on pgs. 8 & 9).

Baud Rate: This 6-gang DIP switch allows the DRI to be
assigned a specific communications baud rate. Baud rates
available are 2400, 9600, & 19200 bps. The factory default is
9600 bps. Only one baud rate should be selected at a time, by
raising the corresponding switch. The two switches on the far
right are not used. The switch on the far left (labelled ‘last’) is
used when connecting multiple devices in a ‘Link Port to Serial
Port’ configuration (see Link Port). From the factory, the ‘last’
switch is up. When connecting multiple devices, the ‘last’ switch
must be switched down on all devices except the final (‘last’)
device in the system (the device with no Link Port connection).

Output can be used to control single or multiple RCII channels.

programmed (via PC Control Software) to perform customized

functions (see Setup on pg. 8).

Logic Inputs: This 9-pin Sub-D (female) connector provides

eight logic inputs for controlling the DRI via contact-closures
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

Inputs 1~4; Pins 5) switch ground point; Pins 6~9) Logic

Inputs 5~8. Logic Input functions may be programmed using the

Control Voltage Outputs is a 15-pin Sub-D (female) connector, which provides up to twelve 0~+10 Volt DC variable control voltages, and
up to two logic outputs. These control voltages & logic outputs provide control of ADVANTAGE

®

DLA93 and RCII products, as well as
other ‘voltage controlled’ and/or ‘logic controlled’ devices. The control voltage & logic output settings are themselves manipulated using
Remote Controls (see pg. 6), Logic Inputs (see pg. 12), and/or RS-232 (see pg. 14).

Control Voltage Outputs have the following pin assignments (right-to-left & top-to-bottom): Pins 1 ~11) Control Voltage Outputs 1~11;
Pin 12) not used; Pin 13) Logic Output 1; Pin 14) Logic Output 2 (Control Voltage Output 12); Pin 15) Ground.

From the factory, the DRI is programmed for controlling an ADVANTAGE® DLA93 (or DLA93tc) Digital-Logic Automixer. When controlling
a DLA93, the DRI Control Voltage Outputs are connected directly to the Remote Control connector on the rear panel of the DLA93, using
the ‘inter-connect’ cable provided with the DRI (see Applications on pg. 16).

Under these circumstances, the DRI Control Voltage Outputs & Logic Outputs control the following DLA93 functions: Control Voltage

Outputs 1~8) Channel 1~8 levels; Control Voltage Output 9) Aux Input level; Control Voltage Output 10) Main Output level;
Control Voltage Output 11) Aux 1 Output level; Logic Output 1) Master/Slave switching; Logic Output 2) Auto/Manual switching.

See the DLA93 Operation Manual for a more in-depth description of these functions.
The DRI Control Voltage Outputs may instead be programmed for controlling other ‘voltage controlled’ devices, such as ADVANTAGE

®

RCII 4-Channel VCA Remote Controls (see Setup on pg. 8).

When controlling ADVANTAGE

RCIIs, Logic Output 2 may be converted to Control Voltage Output 12, via an internal jumper strap (see
below). A custom cable is then wired from the DRI Control Voltage Outputs to the appropriate control terminals of the RCIIs (see
Applications on pg. 17). Each Control Voltage Output can be used to control single or multiple RCII channels (see diagram on next page).

To convert Logic Output 2 to Control Voltage 12: 1) Disconnect the DRI power transformer from the AC outlet. 2) Lay the DRI on a flat
surface, with the top panel facing up and the rear panel facing away. 3) Remove the top panel, which is secured with six screws. 4) Find
jumper J10 (located at the right-rear corner of the circuit board, in front of the Control Voltage Outputs connector). 5) Using needle-nose
pliers, move the jumper strap one pin towards the rear panel (to the ‘spare’ position). 6) Replace & secure the top panel. NOTE: To
convert Control Voltage 12 back to Logic Output 2, simply move the jumper strap one pin towards the front panel (to the ‘logic 2’ position).

Each Control Voltage Output has a range of 0~+10 Volts DC, with a maximum current capability of 4mA. Upper & lower voltage limits may
be set for each Control Voltage Output (see Setup on pg. 8). Logic Outputs 1 & 2 are open collector/negative true logic outputs, with a
maximum sink current of 50mA and a maximum collector voltage of +24 Volts DC.

Logic Outputs 1 & 2 are NPN transistors, with the collectors being the output and the emitters being ground. When a Logic Output is
turned on, the transistor provides a path for DC current to flow. Logic Outputs do not provide any voltage or current. They act only as
switches, with a common ground return. Logic Outputs can be used to control external circuits, such as relays & indicators (se e diagram
below). Logic Outputs may be combined (wired in parallel) to control a common circuit, or individually they may be used to contr ol multiple
circuits. When using Logic Outputs to control relays, protection diodes must be used to suppress high voltage transients that are
generated when the relays turn off.
