Protection Circuit - Hifonics VRX82A Bedienungsanleitung

VARIABLE BASS BOOST
By using the BASS BOOST controller [ 11 ] you are able to increase the bass enhancement from 0 to 12 dB.
ATTENTION: Use the BASS BOOST wisely!
PHASE SHIFT SWITCH
The PHASE SHIFT switch [ 12 ] allows to switch the phase from 0° to 180° to match the output signal with the
vehicle's interior acoustic.
VARIABLE LPF FILTER
Set the desired crossover frequency by using the controller LPF [ 13 ]. Thus to that only the frequencies below
the chosen crossover frequency will be amplified and the subwoofer plays more precisely and efficient. With
the X-OVER SLOPE switch [ 14 ] the slew rate of the LPF filter can be set. The slew rate determines whether
the filtered out frequencies should be attenuated normal (12dB) or high (18dB).
BASS LEVEL REMOTE CONTROLLER
With the included bass level cable remote controller [ 16 ] allows to adjust the bass level e.g. out of the driver's
seat. Connect the remote controller and the BASS LEVEL CONTROLLER terminal [ 15 ] with the enclosed
cable.

PROTECTION CIRCUIT

The POWER LED [ 17 ] lights up green, if the amplifier is in operation.
The PROTECT LED [ 18 ] 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.
