Controls and functions
1 Speaker terminals For connection of the speakers
2 Power terminals
GND -> Ground connection
REM -> Remote antenna terminal [Not for use with High level inputs (5)]
BATT -> +12 Volt
3 Satus indication
GREEN – OK
RED – Error
4 Cinch inputs
Terminal for connection of the RCA wires.
To avoid failure, please use high quality RCA wires.
IMPORTANT!
Do not use the High level inputs and the Cinch inputs parallel, this can damage
the amplifier. Use either the Cinch OR the High Level inputs.
5 High Level inputs
These inputs must be used if your head unit is not equipped with a Low Level Cinch
ouput.
Connect this input to the speaker outputs of your head unit. The amplifier
automatically turns on as soon as a signal is received (Auto On). The remote
connection of the Power- Terminal (2) won’t be used.
IMPORTANT!
Do not use the High level inputs and the Cinch inputs parallel, this can damage
the amplifier. Use either the Cinch OR the High Level inputs.
6 High Pass controller
Set the filter switch to „HIGH“ position.
Adjust the variable HPF crossover frequency to the desired frequency using the
controller. All frequency between 40 and 3000 Hz will be reproduced.
7 Low Pass controller
Only frequencies from 30Hz to 250Hz will be reproduced (depending on the LPF
filter controller position). Set the filter switch to „LOW“ position. Adjust the variable
LPF frequency to the desired frequency using the controller.
8 Mode switch
Adjust the crossover for the chosen utilization.
LPF – Only bass frequencies (below 30Hz - 250Hz) will be reproduced.
FLAT – All frequencies will be reproduced.
HPF – Only middle and high frequencies (over 40Hz – 3000Hz) will be
reproduced.
9 Remote control input
For connection of bass remote control
(GZIA 2130HPX-II & 2235HPX-II optional/1.600HPX-II)
10 Input level controller With this controller you can adjust the input sensitivity.
11 Bass Boost controller For adjusting a Bass Boost at 45 Hz from 0 – 12 dB
High Level Input
Depending on the configuration of your car and sound system, error noises may appear when using the
high level inputs. Please use the additional middle ground-connection of this input to reduce these
noises.
The Auto-On function allows you to use the amplifier without an additional remote connection. This
makes it possible to operate it with an OEM headunit and OEM active systems, which are not equipped
with cinch ouputs or switched remote-outputs.
