VARIABLE HIGHPASS FILTER
If the amplifier is to be used for satellite loudspeakers (mid-range/tweeter loudspeakers), set the switch
(X-OVER, Fig. 1, 5) to "HPF" or for bigger loudspeakers (>20 cm) to "FULL". Set the desired cross-
over frequency on controller (LPF/HPF, Fig.1, 6). Hence, only the frequencies above the chosen cross-
over frequency will be amplified. This effectively minimizes distortions and overloads at lower frequencies.
A good point to start is at 125 Hz.
VARIABLE LOWPASS FILTER
If the amplifier is used to drive a subwoofer, set the switch (X-OVER, Fig. 1, 5) to "LPF". Set the desired
cross-over frequency by using the controller (LPF/HPF, Fig. 1, 6). Hence, only the frequencies below
the chosen cross-over frequency will be amplified and the subwoofer plays more precised and efficient.
A good point to start is at 125 Hz.
VARIABLE BASS BOOST
By using the controller (BASS BOOST, Fig.1, 4) you are able to increase the bass level. The range is
between 0 and 12dB.
Note: Use the bass boost wisely. A too high bass boost could permanently damage the speakers.
PROTECTION CIRCUIT
The LED (POWER, fig. 2, 7) lits up, if the amplifier is in operation.
The LED (PROTECTION, fig. 2, 7) lits up, when the amplifier is overheated, or a short circuit occurs
resp. a too low impedance load is connected to the speaker outputs. If this happens, the internal built-
in protection circuit shuts down the amplifier automatically. The amplifier should work again properly
after you have solved the problems.
