DJUSTMENTS AND SETTINGS

The DB Drive amplifiers are equipped with built-in variable crossover networks allowing

you to select the crossover mode (i.e. Low-Pass/Full/High-Pass or On/Off) and the

desired crossover point. For example if you wish to drive a pair of subwoofers, you can

select the "Low Pass" setting on the amplifier to filter out high frequencies. This will send

only low frequencies to your subwoofers (see example settings below). The cross-over

point should be determined by the speakers operating range. Please refer to speaker

manufactures recommended crossover point.

Filter Selection for Channel 3 & 4

Adjust the frequency to the

desired point for speakers 3 & 4.

Filter Selection for Channel 1 & 2

Adjust the frequency to the

desired point for speakers 1 & 2.

INE TUNE THE SYSTEM

Fine tune the amplifier's input sensitivity

The gain sensitivity control for the DB Drive amplifier is located on the side panel. This

gain control has been included to allow adjustment to properly match the output of the

radio. This is one of the most misunderstood adjustments. By rotating the control in the

clockwise direction, the amplifier's input will become more sensitive and the music will

play louder. This is not a volume control and you will not get more power out of the

amplifier in the maximum position! It may seem to deliver more output, but actually the

system is only playing louder faster as you turn the volume control on the radio. Ideally,

to properly level match the system the goal is to achieve maximum output from the

amplifier without distortion at about ¾ of the volume control.

To determine if the amplifier's gain is set properly, turn the system on and slowly

increase the volume control. You should be able to use about ¾ volume before the

system gets loud but not distorting. It is very important when making these adjustments

that you do not over drive the speakers (at point of distortion) this will cause permanent

damage to the speakers. If you are unable to achieve ¾ volume before distortion you will

need to adjust gain control (in this case you would reduce the gain). The gain controls

should be adjusted very slowly. It may help to have another person to assist you by

adjusting the gain controls while you listen for distortion.
