If the POWER LED lights up, the amplifier is ready for operation.
If the PROTECT LED lights up, a malfunction is indicated. Attend in this case the chapter TROUBLE SHOOTING.
The TWIN SUB switch in position ON effectuates, that the bass remote controller adjusts the level simultaniously on both
3
channel pairs (CH1/2 & CH3/4) in the mono-bridge mode with two subwoofers. In switch position OFF, the bass remote works
only on CH3/4. Also all crossover settings (BASS BOOST, LP/BP, HP, LEVEL) of CH1/2 will be synchronized with CH3/4.
The BASS BOOST CH1/2 and CH3/4 controllers adjust the bass boost enhancement continuously from 0dB to +18dB at
4
45 Hz for the regarding channel pair (Channel 1/2 or Channel 3/4).
The CH1/2 and CH3/4 X-OVER switch selects the required operation mode of the amplifier on the regarding channel pair
5
(Channel 1/2 or Channel 3/4).
Position LP/BP: Lowpass mode (The higher frequencies will be eliminated. Adjustable by the lowpass controller.)
The HI PASS controller works in this operation mode as subsonicfilter and eliminates the lower frequencies (Bandpass-Mode).
NOTE: If this controller is turned to a higher value than the lowpass controller, no sound is hearable.
Position HP: Highpass mode (The higher frequencies will be eliminated. Adjustable by the highpass controller.)
Position FULL: Fullrange mode (The whole frequencies will be amplified).
The LOW PASS CH1/2 and CH3/4 controllers adjust the cut-off point of the frequency range to above for the regarding channel
6
pair (Channel 1/2 or Channel 3/4). The cut-off frequency is continuously adjustable from 30 Hz to 150 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.
7
Select the position 4CH, if you connect two RCA stereo audio cables with CH1/2 and CH3/4 line inputs.
The fader function of your headunit works only in the 4CH mode.
If you have select the 2CH mode, the input signal of LINE INPUT CH1/2 will be routed to the channelpair CH3/4. Due to this, only
one RCA stereo audio cable is required. Therefor the additional available subwoofer lineout (SUB OUT) of your headunit is
recommended in the TWIN SUB mode and no Y-Adaptors are required.
The REMOTE port is for the cable of the enclosed bass remote controller and only to use in the LP/BP mode. With this bass
8
remote controller, you are able to adjust the bass level e.g. from the driver's seat. Please use only the enclosed bass remote
controller and cable.
The HI PASS CH1/2 and CH3/4 controllers adjust the cut-off point of the frequency range to below for the regarding channel
9
pair (Channel 1/2 or Channel 3/4). The cut-off frequency is continuously adjustable from 10 Hz to 1200 Hz (1.2 kHz).
The LEVEL CH1/2 and CH3/4 controllers adjust the input sensitivity of the amplifier to align the audio signal of the head unit
10
for the regarding channel pair (Channel 1/2 or Channel 3/4). The input sensitivity is adjustable from 6 to 0.2 Volts.
The LINE INPUT RCA jacks must be connected with the RCA output jacks of the headunit.
11
By connecting only the CH1/2 jacks, the INPUT MODE switch must be set to the 2CH position.
The LINE OUT RCA jacks provide a linear fullrange audiosignal to supply an additional amplifier.
