Operation elements and in / outputs
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 (3) Fig. 5, 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 (6) to" LPF". And set proper cross-over
frequency with adjusting the control (5) 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 (6) to
"HPF".
Set proper crossover frequency with adjusting the control (7). 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 function (4) 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 (1) is directly output to the LINE OUT (2) L and R
jacks.
Additional amplifiers can be connected to the LINE OUT jacks without additional T-plugs and cables.
