NAD 2200 PE schematics

Sjef · 24th April 2004, 07:45 PM

Does anyone have the schematics (with printlayout ?) of the NAD 2200 PE power amp.

I have got one wich seams to produce about 3,5 Volt of DC on the output of both channels !!?? . Anyone familiar with this problem ? Realy want to cure it to use it as a subwoofer-amp.

Does anyone know what the input impedance of NAD 2200 amp is ? Would like to know because I want to use a passive crossover in front of it at line-level.

Pls adj SVR201&SVR202 set L&R channel DC offset to zero.
Input impedance:more than 20K.

You can email the guy running this eBay ad. I got my 2600 and 2100 manual from him.

Tried to adjust the offset with the mentioned pot's. Nothing happens, offset is still the same. Strange thing is that it is on both channels so I suppose something else is wrong here.

Tried to get the service manual, but noone seem to have it, even NAD itself do not carry them anymore.

HEEEEELP. !!!!
