INPUTS FRONT 1/2CH L+R Low-level RCA signal input for
connection to the head-unit front pre-out.
INPUTS REAR 3/4CH L+R Low-level RCA signal input for
connection to the head-unit rear pre-out.
INPUTS SUB 5CH L+R Low-Level RCA signal input for con-
nection to the head-unit sub pre-out or - if not available - to the ‚dou-
bled‘ rear pre-out (using a pair of Y-adaptors).
HIGHPASS 1CH/2CH Operating mode switch, activates the
highpass filter of the front channels.
FRONT/REAR/SUB/GAIN Separate input
gain/sensitivity controls for all 3 input sections allowing the individual
matching of the amplifier sections to the respective head-unit
(pre-out) output voltages.
HIGHPASS FRONT+REAR Highpass filter frequency
controls for the front and rear satellites allowing the setting of the
respective highpass cut-in frequencies between 40 and 240 Hz.
HIGHPASS 3CH/4CH Operating mode switch, activates the
highpass filter of the rear channels.
LOWPASS CH5 Operating mode switch, activates the lowpass
filter of the sub channel.
LOWPASS SUB Lowpass filter frequency control for the subwoo-
fer channel allowing the setting of the respective lowpass cut-off frequen-
cies between 40 and 240 Hz.
SUBSONICFILTER Activates, resp. deactivates the subsonic
filter of the sub channel.
POWER LED Amplifier status-LED, signalling normal operation
(green).
PROTECT LED Protect mode LED, signalling amplifier malfunction
when lit red, due to shorted speakers, overtemperature etc.
FUSE Fuse for protection of the amplifier-internal electronics
against overload or faulty operation / wrong manipulation.
+12 V Power connection terminal to positive terminal of car battery.
REMOTE/REM Remote switching contact for the automatic
(remote) turn-on / turn-off of the power amplifier from the head-unit‘s
remote (or antenna control) lead.
GROUND/GND Power connection terminal to chassis ground or
negative terminal of car battery (-12V).
FRONT L und R Speaker output terminals for the
front satellite speaker pair (min. impedance 2 Ohms!).
REAR L und R Speaker output terminals for the rear
satellite speaker pair (min. impedance 2 Ohms!).
SUB L und R Speaker output terminals for the sub-
woofer (min. impedance 4 - 2 Ohms!)
