B) VARIABLE LOW-PASS FILTER (50Hz~4KHz)
For use as a dedicated Subwoofer Amplifier, as desired. This activates the Low-Pass filter circuitry, thus allowing
only frequencies below these settings to be amplified.
For normal full-range frequency speaker configuration, set to “FULL”.
For use as a dedicated Subwoofer channel, set filter switch to “BP”. Adjust the desired crossover frequency with
control, thus the input circuit filters out all frequencies below 50Hz……4KHz.
C) VARIABLE HIGH-PASS FILTER (50Hz~4KHz)
For use as dedicated mid high range channel, set filter switch to “Hi”. Adjust variable crossover frequency with
control as desired. The amplifier input circuit filters out everything above 50Hz……4KHz. (dependent on the
adjustment of the frequency control)
D) BASS EQ
By using the bass boost (0-18dB) variable function deepest bass notes at 40Hz are emphasized.
D) CONNECTING HIGH LEVEL INPUTS (FIG.2)
NOTE :
DO NOT USE IN CONJUNCTION WITH LOW LEVEL INPUT JACKS.
CAUTION :
NOTE THAT ONLY POSITIVE (+) WIRES ARE USED. DO NOT CONNECT SPEAKER NEGATIVES (-) FROM CAR STEREO.
