Wow very wonderful and clear!!!! I will always trust them
;
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.
Very good!

Great Job!!! clear and efficient as always!!
it is really nice to have peple that are doing such a good work!!!!!

I must admit, I was very skeptical... $4.99 for a 74 page service manual. I've seen some very poorly scanned manuals on the Internet, but this one is VERY good quality! Even when zooming into 500%. Great Deal!

Description
4dB volume control input. Must be driven at a low impedance. 1dB volume control common pin. (Connected to GND through a capacitor) For the connection of capacitors that compensate for bass and treble in the tone control circuits.
3~5
RT1 ~ RT3
�
A high-frequency compensation capacitor must be connected between RT1 and RT2. A low-frequency compensation capacitor must be connected between RT2 and RT3.

Tone control output. Super bass input. Must be driven at a low impedance. Connected to GND. Not connected. For the connection of RCH super bass compensation capacitors. Fader input. Must be driven at a low impedance. Fader output. The front and rear sides can be attenuated independently. GND. Serial data and clock input for control. Chip enable. Data is written in the internal latch when the chip enable signal goes "L" from "H", and each analog switch is activated. Data transfer is enabled at "H". Generates a 1/2VDD power source. A capacitor must be connected between VREF and GND as a troubleshooting against power ripples. Fader output. The front and rear sides can be attenuated independently. Fader input. Must be driven at a low impedance. For the connection of LCH super bass compensation capacitors. Not connected. Connected to GND. Super bass input. Must be driven at a low impedance. Tone control output. For the connection of capacitors that compensate for bass and treble in the tone control circuit.
