Adjustment of Built-In Crossover (All Models}

Pldcing the switch in the

FULL

position sets the amplifier to

Full Range.

This setting allows

ALL frequencies to pass to the speakers. (Not available on 0600.1, & 01000.1). Placing the

switch in the

HP or LP

position activates the crossover.

Placing the switch in the

position sets the amplifier to the

High Pass

mode, enabling

frequencies

above

the cutoff point to pass.

Placing the switch in the

position sets the amplifier to the

Low Pass

mode, enabling

frequencies

below

the cutoff point to pass.

Turn the crossover adjustment knob all the way down. With the system playing, turn the

crossover adjustment knob up slowly until the desired crossover point is achieved.

Adjustment of the Bass EQ (0400.1, 0600.1, & 01000.1}

After setting the input gain adjustment and crossover, you may choose to add

a small

amount of ··boost"

in the Low frequency region. The bass boost frequency is variable

between 30Hz and 125Hz (0600.1, & 01000.1 ONLY). Remember that the Bass Boost

feature will not fix a poorly designed subwoofer enclosure or subwoofers that didn't sound

good to begin with.

Make sure any

bass EQ or low frequency equalization

from the source unit is set to

OFF

FLAT.

If you have other outboard signal processors with equalization, you should use

those to add boost first and Leave the amplifier's bass boost alone.

2) While playing the same musical selections used during the gain setting process, slowly

increase the Level of the Bass EQ. You should be able to notice a demonstrable change

between 0 and +12dB. If you do not notice much difference, then it will not serve any

benefit to increase the boost further.

If the boost has audible benefits without adding appreciable distortion,

find a level that

suits your taste.

Remember: it's much easier to construct the right subwoofer enclosure

for your Listening preferences than relying on a bass boost control to do the job!

Remember that the Bass EQ feature has an optional dash mounted control included with the

amplifier that will function as an attenuator between the maximum Level set at the amplifier

and OdB of attenuation. It will not add boost beyond the Level you choose at the amplifier.

Troubleshooting

It's imperative that you read the manual fully to eliminate the possibility of mistakes made from

assumptions about how you "think" the amplifier might work versus how it's recommended

to be installed. If the amplifier does not appear to be working, check obvious things first

such as blown fuses, incorrect wiring configurations, poor or Loose connections, crossover,

Bass EQ, and gain controls set incorrectly, etc. These elements are the most common cause

of initial problems, so take your time and double check all of yourwork before assuming

there's a serious problem.
