PROTECTION CIRCUIT
The PROTECT LED [ 15 ] lights up red, when the amplifier is overheated, or a short circuit occurs respective
a too low impedance load is connected to the speaker outputs. If this events, the internal built-in protection
circuit shuts down the amplifier automatically. The amplifier should work again properly after you have solved
the problems.
The POWER LED
[ 16 ]
lights up green, if the amplifier is in operation.
VARIABLE BASS BOOST
By using the BASS BOOST controller
[ 10 ]
you are able to increase the bass enhancement from 0 to 12 dB.
ATTENTION: Use the BASS BOOST wisely!
VARIABLE LOW PASS FILTER
Set the desired crossover frequency by using the controller LOW PASS [ 12 ] . Thus to that only the frequencies
below the chosen crossover frequency will be amplified and the subwoofer plays more precisely and efficient.
PHASE SWITCH
The PHASE SHIFT switch [ 11 ] allows to switch the phase from 0° to 180° to match the output signal with the
vehicle’s interior acoustic.
BASS LEVEL REMOTE CONTROLLER
With the included bass level cable remote controller [ 13 ] allows to adjust the bass level e.g. out of the driver’s
seat. Connect the remote controller and the REMOTE terminal [ 14 ] with the enclosed cable.
