Providing the manual works fine, quickly and without any problems for an acceptable price. After printing the service manual it took me only a short time to repair my carradio from Clarion. Thank You! Greetings from Heiko
I was searching a way to modify the original phono-in entry (for connection of vynil disc player, with RIAA equalization) to a line-in entry (for connection of modern analog entries, eg. ipod, mp3player).
This service manual gave me the correct hints.
It contains very useful infos for repairing and modifing the hi-fi, such as disassembling instructions, block diagrams, schematic diagrams, PCB prints, replacement parts list.
2.2 PANEL FACILITIES
4 Crossover knob (CROSSOVER)
When using the subwoofer, set the upper frequency limit for the subwoofer (50 Hz to 200 Hz) so that it complements the output from your other speakers. When using the bass management features of an AV receiver, set to BYPASS ON in order to use the low-pass filter of the AV receiver for high quality sound.
5 Bypass switch (BYPASS)
When set to ON, the audio signal is routed directly to the woofer unit, bypassing the amplifierâs filter.
6 Phase switch (PHASE 0Âº /180Âº)
When set to 180Âº, the output phase becomes the reverse of the input signal, and when set to 0Âº, it is in the same phase as the input signal. â¢ Normally, the switch is set to 0Âº. But when the sound connection between the subwoofer and the left and right speakers sounds unnatural, try switching to 180Âº and set the switch in the position where the sound is natural. â¢ When using two or more subwoofers together, make sure that the phase switch of all of them are set to the same position.
1 Power Indicator (POWER ON)
Lights green when the power has been switched ON.
â¢ If you are planning on switching the unit OFF for a long period of time, make sure to check that the indicator light has gone out after switching OFF.

Connect to the SUBWOOFER PREOUT terminal of an amplifier or receiver, with a RCA plug cord.
