Operation elements

SETTING THE INPUT AND SENSITIVITY

The regulator for input sensitivity is used to adapt amplifier for each car radio or tape deck. Turn the
volume control of your radio to central position and adjust the input-level control (2) Fig. 6, to produce
medium volume. This setting can provide sufficient power and optimum Signal to Noise (S/N) ratio.
CAUTION:  Do  not  run  the  amplifier  in  high  volume  for  long  time,  otherwise  the  loudspeakers  will  be

damaged.

LOW-PASS FILTER WITH ADJUSTABLE CROSSOVER FREQUENCY

If  the  unit  is  used  as  a  subwoofer  amplifier,  turn  the  switch  (5)  to"  LPF".  And  set  proper  cross-over

frequency with adjusting the control (3) to make the filter match the timbre requirement of the installed
woofer.
The crossover slope of the filter can accurately reduce the medium and high frequency ranges.

HIGH-PASS FILTER WITH ADJUSTABLE CROSS-OVER FREQUENCY

If the amplifier is used for satellite loudspeakers (mid-range/tweeter loudspeakers), turn switch (4) to
"HPF". Set proper crossover frequency with adjusting the control (3). The frequencies only above the
setting will be amplified. This can effectively minimizes distortions caused by excessive membrane
movement at the low frequencies. And the result does not reduce the bass level when it is used for small

power-supply loudspeakers.

BASS-BOOST

Use the bass-boost switch (6) to eliminate harmonic distortion of the lower bass frequencies and weaken

the bass faction.

OUTPUTS FOR CONNECTING ADDITIONAL AMPLIFIERS

The input signal of the LOW INPUT connections L and R is directly output to the LINE OUT L and R jacks

(1). Additional amplifiers can be connected to the LINE OUT jacks without additional T-plugs and cables.
