Oxmoor DCA-2 - Manual (Page 6)

DCA-2 SET-UP
FACTORY SET-UP
The front panel trim pots are factory set to unity gain. The Preset
control and the Priority control are factory set to #8 (-21dB
reference to 0dB).
PRESET SET-UP
1. Remove AC power if unit is powered up.
2. Use a small flat-blade screwdriver to set the Preset to the
desired position.
3. Connect the AC power.
PRIORITY SET-UP
Use a small flat-blade screwdriver to set the Priority to the
desired position.
PRELIMINARY CHECKOUT
To verify that the DCA-2 and RC-16 are operating when
received, we recommend that you use a short jumper cable (one
is supplied by the factory with your system) to connect an RC-16
Remote Control to Channel A of the DCA-2. Apply AC power to
the DCA-2 and observe the circular LED array (Virtual Pointer)
around the RC-16 knob. An LED should indicate the attenuation
position. Rotate the knob and verify that the Virtual Pointer is
operating (i.e., that the LED moves from -90 dB [mute] to 0 dB
[unity gain]). Repeat this procedure for Channel B.
If there is a problem, see TROUBLESHOOTING, page 10.
TRIM POTS SET-UP
Use a small flat-blade screwdriver to set the trim pots to the
desired position between -15 dB and +15 dB. Full counter-
clockwise is -15 dB; full clockwise is +15 dB; 12 o’clock is unity.
