Installing the Remote Level Controller

The D3 600.1 and the D3 1000.1 come packaged with a remote level control. This allows you to control the level by attenuating the amplitude or increasing (up to the maximum set-point) of the amplifier’s input gain control. This control does not add additional bass boost, it simply allows you to control the level to suit your tastes.

1)Locate a position in the front of the vehicle where this will be easy to reach. Common locations are on, in, or under the dash, in the center console, or in the glove box.

2)If you will “surface mount” the unit, attach the bracket using the sup- plied hardware to your chosen location (See illustration). Proceed to step 4

3)If you will be “flush mounting” the unit, you must remove the knob and fascia assembly from the housing first. Then proceed to cut an opening measuring 2” wide (5cm) x 5/8” high (2.2cm). You will need to allow about 1 inch (2.5 cm) of clearance behind the opening for installation and cable access. (See illustration)

4)Route the telephone style data cable back to the amplifier location and connect into the remote level port. Test to make sure the operation is functioning.

Perform a final check of the completed system wiring to ensure that all connections are accurate. Check all power and ground connections for frayed wires and loose connections which could cause problems. Install in-line fuse near battery connection at this time. Prepare to make some adjustments to fine tune your audio system for optimum performance.

Adjustment of Input Gain

To adjust the gain setting, turn the amplifier gains all the way down (counterclockwise). Turn the source unit volume up until distortion is audible and then turn it down a bit until the distortion is inaudible. This will be NEARLY full volume on most source units, perhaps one

or two “clicks” down from maximum volume. Next, increase the amplifier gain setting until adequate volume is achieved.

NOTE: Ideal signal to noise and dynamic range are achieved with the gain at minimum. Most users find adequate gain and volume is achieved at about halfway in the adjustment range. Avoid setting the amplifier gain very high as noise and distortion will increase signifcantly.
