3.GND - Power return connection. Connect this terminal directly to the sheet metal chassis of the vehicle, using the shortest wire necessary to make this connection. Always use wire of the same gauge or larger than the (+) 12 volt power wire. The chassis con- nection point should be scraped free of paint and dirt. Use only quality crimped and/or soldered connectors at both ends of this wire. DO NOT connect this terminal directly to the vehicle battery ground terminal or any other factory ground points.
4.Top cover lock - Use the key provided or the 3mm hex key to unlock and remove the top cover.
NOTE: Make all connections to power, ground, speakers, and remote terminals before final positioning and installation of the amplifier in the vehicle. The top cover needs to be removed to fasten some of the connections. These connections once made are secured by tightening the set screws with the Allen wrench provided. These fastening set screws are labeled and located on top of the amplifier at either end, directly above their associated connectors.
TOP Panel Layout
NOTE: Top cover must be removed to access the following controls (Refer to the Removing the Top Cover section of this manual).
1.ON/OFF - Turns the
2.Q - Continuously adjusts the “Q” boost of the
3.FREQ - Adjusts the center frequency of the
4.PHASE - Provides either 0 or 180 degree phase shift of the ampli- fied output (speaker) with respect to the input signal to facilitate
the best bass performance.
5.SLOPE - Selects the crossover roll off between 12db and 24db per octave.
6.LOW PASS - Adjusts the upper crossover frequency of the ampli- fier.
7.LINE OUT - Has three settings: Gain, Master and Copy. This con- trol is set according to how the amplifier is used, as a stand alone, a master or a slave respectively. Leave the amplifier set to gain (default) if it is not connected to another amplifier. When con- nected in combined amplifier configurations, set to master when the amplifier is used as a master, set to copy when used as a slave (Refer to the Amplifier Wiring section of this manual).
8.GAIN RANGE - Selects the input sensitivity range to either High (for high power head units) or Low (for line level head units).
9.GAIN - Continuous adjustment for full power output used to match the amplifier input to the source output level.
