F. Re-connect the fuse or circuit breaker. Power up the system and the red LED should be lit. There may be a 2 -3 second delay from the time that the source unit is turned onto the time that the LED on the amp lights. This is normal. Once the amplifier power LED is on and the source unit is playing, you should have sound coming from the speakers.

Wiring Tips

. Use grommets when running cables through any metal or sharp plastic to prevent accidental shorting or shearing.

. Be certain that the cables don’t interfere with normal operation of the vehicle’s high current circuits and vehicle management systems (engine computers, relays, etc.).

LEVEL SETTING

The input levels are adjusted by means of a stereo level control located next to the input connectors. When the amplifier is operated in the mono/bridged mode, only the right channel input is active.

A. Turn the input level control on the amp to a minimum position (fully counter-clockwise).

B. Set source unit volume to approximately 314 of full volume.

C. While playing dynamic source material, slowly increase the amplifier’s input level until a near maximum undistorted level is heard in the system.

D. If you are using the amplifier to drive subwoofers, you may want to use the bass boost circuit. First, engage the switch on the bottom of the amplifier, secondly, slowly adjust the level on the front panel to your preference.

PROTECTION CIRCUITS

Your Granite amplifier is protected against both overheating and short circuits by means of the following circuits:

A main power supply fuse

A fail-safe thermal protection circuit activating at 85OC

Over-current Channel Circuit Breakers

Short-circuit shutdown
