Profile CL440 A, F

(Please note: If you intend to use the amplifier in the Tri-mode configuration, it is necessary

to set the crossover control to the "FULL" setting in order to receive full range output)

The Clarus amplifiers are equipped with a built-in variable crossover network allowing you to

select the crossover type (i.e. Low-Pass or Hi-Pass) 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 crossover point should be determined by the speakers

operating range. Please refer to speaker manufactures recommended crossover point.

Select the crossover type on the

amplifiers side panel.

(Low-pass is selected in this example for subwoofers) A Sub Sonic Filter is provided for the

CL600M to filter out sub sonic frequencies below

the audible range that would normally waste the

amplifiers power.

You can add up to 18dB bass boost by

increasing the Bass Boost control.

ADJUSTING THE X-OVER, BASS AND SUB SONIC FILTER

Access to the gain sensitivity control for the Clarus

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 3/4 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 3/4 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 3/4 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.
