DESCRIPTION OF OPERATION

There are two RCA inputs on the LINE INPUT, each of which is controlled in mono. The upper input
7
LOW VOLTAGE is suitable for low level signals from 0.4 to 3.6 volts. At the lower input HIGH VOLT-
AGE you can connect a high level signal from 1.0 to 9.0 volts, such as that provided by a DSP.
ATTENTION: Never connect a high-level signal from a loudspeaker output here.
8 The INPUT SENS. determines the input sensitivity of LINE INPUT in order to adapt the incoming
signal from the head unit (car radio).
This SUB SONIC controller limits the ultra low and not audible frequencies of the audio signal down-
9
wards to avoid mechanical and electrical overloading on the subwoofer. The crossover frequency is
adjustable from 10 to 100 Hz and depends on the size of the subwoofer. Make sure that this controller
is not set higher than the LOW PASS controller, otherwise no sound can be heard.
10 The LOW PASS controller limits the frequency of the audio signal upwards. The crossover frequency
is adjustable from 50 Hz to 5.000 Hz (5 kHz).
11 The BASS BOOST controller regulates the bass enhancement of the signal continuously from 0 dB
to +12 dB. With the BOOST FREQ. controller you can set the frequency of the bass enhancement
between 30 Hz and 70 Hz.
If the blue POWER LED lights up, the amplifier is ready for operation.
12
If the red PROTECT LED lights up, there is a malfunction. Then follow the instructions in chapter
TROUBLESHOOTING on page 22.
If the orange CLIP LED lights up, the input signal is overloaded. Then turn the INPUT SENS. controller
(see section 8) back accordingly until the LED goes out.
13 Connect the subwoofer to the SPEAKER OUTPUT output accordingly. Pay attention to correct polar-
ity. The minimum impedance of the subwoofer should not be less than 1 ohm.
