HIGH LEVEL INPUTS & AUTO TURN ON
The high level inputs under HIGH LEVEL INPUT (Fig. 5) is suitable to connect the device input with speaker
wires, if your head unit is not equipped with pre-amplifier RCA outputs. Extend therefor every regarding speak-
er cable from your head unit with appropriate speaker cables from your car audio retailer to the mounting
location of the amplifier. Then connect the each matching loudspeaker cable with the cables of the included
High Level Input jack.
ATTENTION: Never use the high level inputs and the RCA inputs at the same time. This may damage
the device seriously.
The amplifier detects a voltage rise (6 Volts) with a so called "DC Offset" over the connected input signal on the
high level inputs under HIGH LEVEL INPUT (Fig. 5) when the head unit will be switched on. Hence, the ampli-
fier will also be turned on. As soon as the head unit will be turned off, the amplifier turns also automatically off.
In this case the turn-on connection REM (Fig. 2,2) is not needed.
ATTENTION: The Auto turn-on function usually works with 90% of all head units, because they are equipped
with "High Power"-outputs. Only with a few older and head units the Auto turn-on function is not working.
VARIABLE HIGH PASS FILTER
If the amplifier is to be used for mid-range/tweeter loudspeakers, set the switch X-OVER MODE (Fig. 1,3) to
HP. Then set the desired cross-over frequency on the HIGH PASS controller (Fig. 1,2). Thus to that 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.
If you use big loudspeakers (>20 cm) set X-OVER MODE (Fig. 1,3) to FULL. In this case, the HIGH PASS
controllers (Fig. 1,2) are without function.
VARIABLE LOW PASS FILTER
If the amplifier is used to drive a subwoofer on REAR, set the switch X-OVER MODE (Fig. 1,3) to LP/BP. Set the
desired cross-over frequency by using the controller LOW PASS (Fig. 1,4). Thus to that only the frequencies
below the chosen cross-over frequency will be amplified and the subwoofer plays more precise and efficient.
In LP/BP mode, the controller HIGH PASS (Fig. 1,2) can also be used to limit the frequency response down-
wards, for example to produce a bandpass/subsonic signal. ATTENTION: If the controller HIGH PASS (Fig.
1,2) is set higher than the he controller LOW PASS (Fig. 1,4, no audio signal is heard.
VARIABLE BASS BOOST
By using the BASS BOOST controller (Fig. 1,8) you are able to increase the bass enhancement from 0 to 12
dB. ATTENTION: Use the BASS BOOST wisely!
BASS LEVEL REMOTE CONTROLLER
With the included cable remote controller, the bass level can be adjusted e.g. from the driver's seat. Connect
the remote controller and the BLC REMOTE connection (Fig. 1,7) with the enclosed cable. The remote control-
ler should only be used when operating the amplifier in LP/BP mode with a subwoofer.
