G)+ 12V: The +BATT power supply connector
is
dedicated
to
receiving the power supply cable ensuring the link between
the
amplifier
and the postive (
+)
terminal
of
the battery.
@GND:
The
GND
power supply connector (ground)
is
dedicated to receive the negative power supply wire linking the
amplifier
and the vehicle chassis.
@REM:
The
REM
connector ensures the link between the
IBUS
20
and the source (the
car
radio) via a
REM
or
REMOTE
output
of
the
car
radio. It permits to automatically switch on the amplifier
as
soon
as
the source (the
car
radio)
is
turned
on).
In
some cases, the original head unit (OEM) does
not
have the remote wiring so they cannot send a signal
for
the start up
of
the IBUS20 enclosure.
We
advise to put
out
the cable
of
the ISO plug and connect the blue cable on a
"plus"
terminal after contact.
Be
careful
to
put
off
the AUTOPOWER
ON
connector (Nb 13).
If
you
do
not
follow
these
guidelines, the IBUS20 may not give optimum performance.
@HI
LEVEL
IN
PUT:
The
HI
LEVEL
INPUT terminal permits
to
connect the
car
radio
to
the amplifier via the car radio
speaker outputs and the high-level connector supplied in the packaging.
®IN
PUT:
The RCA sockets permit to convey the low level signal
of
the head unit
to
the amplifier.
@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.
(VREMOTE
CONTROL
PLUG: the REMOTE
CONTROL
connector
is
dedicated to the wiring
of
the remote control
supplied.
@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
0.2V
to
SV.
®SUBSONIC:
The SUBSONIC rotary potentiometer permits
to
set
the high-pass filter value. The chosen value defines
the frequency from which the signal
is
amplified.
@)BASS BOOST: The
BASS
BOOST
rotary potentiometer permits
to
increase the bass level from 0 to +
l8dB.
The central
frequency
is
60Hz.
@
LO
PASS:
The LO
PASS
rotary potentiometer permits the setting
of
the low-pass filter value. The selected value defines
the frequency until which the signal
is
amplified.
@PHASE:
The
PHASE
selector permits to adjsut the phase setting
of
the bass chanel according to the installation.
To
determine the correct position
of
this inverter, simply check if it provides the maximum
of
bass
frequencies.
@Auto
Power
On:
In
ON
mode, it
1
s not necessary
to
connect the remote cable if you
1
re
using the high level inputs.
Do
not function with the RCA inputs. However, we prefer the direct remote wiring on a "plus after contact"
(cf
Nb
3).
LED:
The light indicator permits to check the correct working
of
the amplifier. When the
LED
is
green, it means the amplifier
@is
on and it
1
s working correctly. WHen the
LED
is
red, it means the amplifier
is
in protection mode following a dysfunction
(overheating, wrong wiring, ...
).
