INSTALLATION
Installation must be made by qualified service personnel, and must meet all local codes.
Before starting connections, please note that the left and right attenuator circuits are completely isolated
from each other to prevent instability when used with certain types of amplifiers which have floating
grounds. If the amplifier to be used has common grounds between channels, a 3 wire system can be used
between amplifier and control, but it will be necessary to connect a jumper between the control ground
returns (L- & R-). If one ground is open, there will be no output on the ungrounded channel at any
attenuator setting.
1. Make connections by stripping wire insulation back about 3/16". Twist any loose strands tightly.
2. Insert the wires from the amplifier into the INPUT openings of the connector, hot to hot and ground
to ground, then tighten screws. Check for stray wire strands that might cause a short circuit. Make
sure the metal part of the screw connector engages the bare wire, NOT the insulation!
3. Similarly, connect speaker wires to the control OUTPUT openings and tighten screws.
4. Install control in its operating location. Suggestion: Leave control 3 or 4 positions CCW from
maximum before firing-up the system for the first time to avoid "blasting" the speakers, while still
having enough sound to observe operation.
