DCA-2 & RC-16 CONNECTIONS
DCA-2 PROGRAM INPUT AND OUTPUT CONNECTIONS
(Refer to Figure 5.0)
The DCA-2 Digital Control Attenuator provides connections
for two program channels. The unit can operate as a two
channel mono or as a stereo unit.
The Program Input connections are made through female,
XLR-type, 3-pin connectors. The Program Output connections
are made through male XLR-type 3-pin connectors.
DCA-2 PROGRAM INPUTS
(Refer to Figure 5.1)
DCA-2:
Pin 1 = Shield, Pin 2 = High, Pin 3 = Low, electronically
balanced inputs accept balanced or unbalanced signals from
line-level devices. Nominal input level is +4 dBu with
maximum input level of +20 dBu.
DCA-2 PIN-OUTS FOR REMOTE CONTROL
(Refer to Figure 5.4)
The DCA-2 Digital Control Attenuator provides female 6-pin
modular TELCO connectors for interface to the Oxmoor
RC-16.

DCA-2 PROGRAM OUTPUTS
(Refer to Figure 5.2)
DCA-2:
Pin 1 = Shield, Pin 2 = High, Pin 3 = Low, electronically
unbalanced outputs. Recommended load impedance is 600
ohms or greater. Maximum output level is +20 dBu.
DCA-2T:
Pin 1 = Shield, Pin 2 = High, Pin 3 = Low, electronically
balanced outputs accommodate balanced or unbalanced lines.
Recommended load impedance is 600 ohms or greater.
Maximum output level is +20 dBu.

RC-16 PIN-OUTS
(Refer to Figure 5.5)
The RC-16 Remote Control provides female 6-pin modular
TELCO connectors for interface to the Oxmoor DCA-2
Digital Control Attenuator and other RC-16 Remote Controls.
Connect the OUT jack of the RC-16 to the IN jack of the
DCA-2. If using round cable, it is important to connect the
RC-16’s PRIORITY to the DCA-2’s PRIORITY, the RC-16’s
COUNT UP to the DCA-2’s COUNT UP, etc.
When “daisy-chaining” RC-16s, take the OUT jack of one
RC-16 to the IN jack of the next RC-16. You can “daisy-
chain” a total of eight RC-16s for each DCA-2 unit.
