FUNCTIONS AND OPERATIONAL CONTROLS
1
The
LINE INPUT RCA jacks
must be connected with the RCA output jacks of the headunit.
3
The
LEVEL controller
adjusts the input sensitivity of the amplifier to align the audio signal from the head unit.
The input sensitivity is adjustable from 6 to 0.2 Volts.
6
The
SUB SONIC controller
(Subsonicfilter) limits the ultralow and not hearable frequencies of the audiosignal to below, to avoid
a mechanical and electical overloading on the subwoofer. The cut-off frequency is adjustable from 15 to 55 Hz and depends on
the size of the subwoofer.
NOTE: If this controller is adjusted higher than the LOW PASS controller, no audio signal may be audible.
The
REMOTE port
is for the cable of the enclosed bass remote controller and only to use in the MASTER mode. With this bass
remote controller, you are able to adjust the bass level e.g. out of the driver’s seat. Please use only the enclosed bass remote
controller and cable.

The optional BALANCED INPUT is unlike the regular RCA-cables insusceptible against interspersion and interferences of the
vehicle’s electronics. You need therefor a Balanced-Line-Transmitter with a special cable, which can be connected between the
head unit and the amplifier. The Balance-Line-Transmitter is not included in the scope of delivery.
Check the further information on page 27. Never use the Balanced-Input and the RCA-Inputs at the same time.
4
The
PHASE controller
allows to adjust the phasing between 0° and 180°. Thereby you are able to adjust the subwoofer
perfect to the vehicle’s acustics.
5
The
EXTENDED BASS CONTROL controllers
allow a extensive adjustment of the bass frequencies.
The
SUB BOOST controller
defines the bass bosst from 0 to 18dB.
With the
FREQ RANGE controller
you are able to adjust, on which frequency the bass boost (SUB BOOST) is effictive.
The range goes from 20 to 80 Hz.
With the
Q CONTROL controller
defines the Q-Factor of the Bass Boost continuously, so that the playback quality of the cut-off
frequency can be adjusted. Thereby you are able to adjust perfect transitions between the loudspeakers. Check also page 23.
• WIDE
equates a Q-Factor of
Q 0,3
(arrow left below) = very wide frequency range.
•
NARROW
equates a Q-Factor of
Q 1,0
(arrow right below) = very narrow frequency range.
•
Q 0,5
/ LINKWITZ-REILLY
is the standard-setting, this means the arrow points up (12 o’clock position).
• Q 0,7 / BUTTERWORTH
is located at the arrow position right (3 o’clock position)
POWER/PROTECT
If the POWER LED lights up, the amplifier is ready for operation.
If the PROTECT LED lights up, a malfunction is indicated. Check in this case the chapter
TROUBLE SHOOTING
.
10
The
MODE switch
selects the required operation mode of the amplifier.
In the
SLAVE-Mode
the amplifier works as a SLAVE amp, this means only the audiosignal of the MASTER amp will be amplified.
All controllers on the SLAVE Amp are without function and will be assumed by the MASTER amp.
In the
MASTER-Mode
(Low Pass mode) you are able to limit the frequencies to above with the LOW PASS controller. All controllers
are active.
NOTE: By using only one amplifier, the Mode-Switch must be set to the position MASTER.
7
The
LOW PASS controller
adjusts the cut-off point of the frequency range to above. The cut-off frequency is
continuously adjustable from 35 Hz to 250 Hz.

11
The
SLAVE IN/OUT RCA jacks
are suitable to connect an additional amplifier in MASTER/SLAVE mode.
Check the chapter
Interconnection Example: MASTER/SLAVE
