High Level Input Connection

If the car stereo not does not provide low-level outputs,

the amplifier may be connected via the speaker (high-

level) outputs from the stereo. Wire the speaker leads

from the car stereo to the 5-pin adaptor harness as

shown in the diagram (shielded cable is not required for

this application) and plug the connector into mating High-

Level Input socket on the amplifier. Carefully splice and

insulate all wire connections.

Adjust it to the appropriate position for the characteristics

and crossover frequency requirements of the speaker

system with which the amplifier is being used.

HPF Crossover Frequency Control

This Control selects the crossover frequency when the

Mid-High Crossover is in the "HPF" setting.

Adjust it to the appropriate position for the characteristics

and crossover frequency requirements of the speaker

system with which the amplifier is being used.

Bass Boost Frequency Control

Allows the addition of up to +18dB increase in sound

level in lower frequencies (0~18dB).

From the system. If, however, there is still output from

the amplifier when the car stereo volume control is at its

minimum setting, or the output level increases too fast

with a small rotation of the volume control, adjust the

Level control to decrease the output from the system.

Once the correct setting is found, these controls should

not require any further adjustment.

Crossover Selector

This switch allows selection of the frequency filters that

permit the amplifier to be used to reproduce the entire

audio range or just the bass range.

In the "FULL" position of the switch, the response is

flat and unaffected so the entire audio frequency

range is reproduced by the amplifier. Use this setting

if the amplifier is being used to power a full range

speaker system.In the "LPF" (Low-Pass Filter) setting,

only the bass frequencies below the frequency set by

the Crossover Frequency Control will be amplified

and fed to the speakers. Use this setting if the

amplifier is being used to power a sub-woofer speaker

system.

HPF(High-Pass Filter): Only MD- high tone

(50Hz-250 Hz) Speaker.

LPF Crossover Frequency Control

This Control selects the crossover frequency when the

Sub woofer Crossover Selector is in the "LPF"

setting.
