QUAD MIC PREAMP
Installing the Optional Second QMP-4 Mic Preamp
The optional second QMP-4 comes complete with mounting hardware.
The ribbon cable, installed at the factory to provide power to the pre-installed
QMP-4 card, also includes a second plug (“Connector” on the picture above)
for connecting the optional QMP-4 card. Handle the 10-pin plug on the
ribbon cable assembly with care. Perform the following steps to install the
QMP-4:
• turn off the power to the console;
• swing the meterbridge up and back until it rests in a fully opened
position;
• plug in the ribbon cable connector to the 10-pin boxed header on the
QMP-4 board (CT7);
• attach the QMP-4 preamp assembly directly to the right of the factory
installed preamp (located at the lefthand end of the meterbridge), using four
type 4-40x1/4 pan head screws and four nylon standoffs through the four
predrilled holes on the meterbridge rear (“Optional QMP-4 Area” on the
picture above); orient it to match the factory installed QMP-4;
• connect the required audio wiring to the 12-pin plug terminals on the
QMP-4 card, referring to the “Hook-Ups” chart (see pages 2-3 - 2-5);
• close the meterbridge.
This completes the optional QMP-4 installation procedure.
