'D
+ BATT: The power supply connector + BAD is dedicated to receive the power supply wire linking the amplifier and the battery positive
terminal (+).
~)GND
: The GND power supply connector (ground) is dedicated to receive the negative power supply wire linking the amplifier and the
vehicle chassis.
@FUSE : The FUSE connector is dedicated to receive the fuse(s) of the amplifier. In case of replacement, make sure of the perfect
conformity of the amperage.
@INPUT : The RCA sockets permit to convey the low level signal of the head unit to the amplifier. CAUTION: The Solid 4 amplifier has
4 RCA inputs for channels 1, 2, 3, 4. The FRONT input corresponds to the speakers situated in the front of the vehicle, whereas the REAR
input corresponds to the speakers situated at the rear of the vehicle.
®HI lEVEl INPUT: The HI lEVEL INPUT permits to connect the head unit to the amplifier via the speaker outputs of the head unit and
the high-level connector supplied in the packaging.
CAUTION: Only use these inputs if the head unit doesn't have RCA type low level output.
CAUTION: The Solid 4 amplifier is supplied with 2 high-level connectors. The first connector is dedicated to channels 1 and 2, whereas the
second connector is dedicated to channels 3 and 4.
@SPEAKERS : The SPEAKER connectors provide the link between the amplifier and the speaker crossovers (or the speakers if the crossovers
are integrated). You MUST respect the polarities (+ amplifier + crossover or + speaker / - amplifier - crossover or - speaker)
CAUTION: the speaker output of the Solid 1 amplifier is ONLY dedicated to the connection of one or several subwoofer(s).
CDREMOTE CONTROL PLUG: The REMOTE CONTROL connector is dedicated to the connection of the remote control supplied with the
Solid 1 and Solid 4 amplifiers. This attachment permits a setting of the amplifier gain.
CAUTION: The REMOTE CONTROL connector of the Solid 4 amplifier ONLY works on the rear channels.
®L1NE OUT: The RCA sockets of the Solid 1 amplifier permit the connection of a second amplifier in order to transmit the original signal
from the head unit, without having to convey additional RCA wires from the vehicle front to the additional amplifier.
®GAIN : The GAIN rotary potentiometer permits to adjust the signal level coming in the amplifier. CAUTION: increasing the input gain
doesn't mean more power, but more noise. The tension gain varies from O.2V to 5Y.
CAUTION: The Solid 4 amplifier has 2 GAIN rotary potentiometers. The CH 1-2 GAIN permits to control the FRONT speaker outputs,
whereas the CH 3-4 GAIN permits to control the REAR speaker outputs.
@SUBSONIC : The SUBSONIC selector is the equivalent of a HI PASS crossover ONLY dedicated to the subwoofer output of the Solid
1 amplifier. The crossover activation permits to avoid distortion. The SUBSONIC crossover has a cut-off frequency situated at 35Hz for a
24dB/octave slope.
®
lO PASS: The lO PASS rotary potentiometer (Solid 1 amplifier only) permits the setting of the low-pass filter value. The selected value
defines the frequency until which the signal is amplified. The filtering slope is 24dB/octave. This crossover is to use only when the amplifier
is linked ta a subwoofer, but IN NO CASE A LARGE BAND KIT.
@BASS BOOST: The BASS BOOST rotary potentiometer (Solid 1 amplifier only) permits to increase the bass level from 0 to +9dB. The
central frequency is 60Hz.
:])')PHASE : The PHASE selector (Solid 1 amplifier only) permits to adjust the bass channel phase setting according to the installation.
@CROSSOVER : The CROSSOVER switch (Solid 2 and Solid 4 amplifier only) permits to activate, up to your choice, a high-pass filter
(HPF), a low-pass filter (lPF) or no filter at all (FUll).
CAUTION: The CROSSOVER switch situated on top of the setting panel of the Solid 4 amplifier is related to channels 1 and 2; whereas the
one at the bottom of the panel works on channels 3 and 4.
@FREQ : The FREQ potentiometer permits to determine the cut-off frequency of the selected filtering mode. In HPF position, this frequency
will be the frequency from which the signal will be transmitted to the speakers.
@WARNING LIGHT: The warning light permits to check the good working of the amplifier. The white color of the lED (light-emitting
diode) means that the amplifier is live and that its working is normal. The red color of the lED indicates that the amplifier is on protection
after any dysfunction (thermal overload, faulty wiring, ... ).
~lt EXTERNAL REMOTE CONTROL: The remote control supplied with the Solid 1 amplifier permits to control the speaker output level
in order to independently manage the subwoofer level. The remote control supplied with the Solid 4 amplifier permits to control the REAR
speaker output level only for channels 3 and 4.
