The
BASS LEVEL CONTROLLER
port is for the enclosed bass remote in LP/BP mode. With this bass remote controller you
are able to adjust the bass level e.g. from the driver’s seat. Please connect only the enclosed bass remote controller and cable.
POWER/PROTECT
If the
POWER LED
lights up, the amplifier is ready for operation.
If the
PROTECT LED
lights up, a malfunction is indicated. Refer in this case to the chapter
TROUBLE SHOOTING.
The
X-OVER CH3/4
switch selects the required operation mode of the amplifier on the channels 1/2.
LP:
Lowpass mode (The higher frequencies will be eliminated. Adjustable by the lowpass controller.)
HP:
Highpass mode (The lower frequencies will be eliminated. Adjustable by the HP controller.)
FULL:
Fullrange mode (The whole frequencies will be amplified).
The
X-OVER CH3/4
switch selects the required operation mode of the amplifier on the channels 1/2.
DUPE:
This mode should be selected, if you want to run 2 subwoofers bridged in LP mode. The DUPE mode passes (duplicate)
the signal from CH3/4 to the line input section of CH1/2. All controllers and settings except the LEVEL controller are then without
function. The LINE IN RCAs of CH1/2 are deactivated.
HP:
Highpass mode (The lower frequencies will be eliminated. Adjustable by the HP controller.)
FULL:
Fullrange mode (The whole frequencies will be amplified).
The
CH3/4 LP
controller adjusts the cut-off point of the frequency range to above for the channels 3/4. The cut-off frequency is
continuously adjustable from 30 Hz to 250 Hz.
The
INPUT MODE
switch must be in 2CH position, if you connect only one RCA stereo audio cable with the CH1/2 line inputs.
Select the position 4CH, if you connect two RCA stereo audio cables with the CH1/2 and CH3/4 line inputs. The fader function
of your head unit works only in the 4CH mode.
If you have selected the 2CH mode, the input signal of LINE INPUT CH1/2 will be routed to the channels 3 and 4. This means
only one RCA stereo audio cable is required. When you operate two subwoofers, you can also use the subwoofer output from
the head unit in this configuration.
