I have discovered a strange problem with my integrated amplifier (NAD
320BEE).

If I connect either of my two VCRs inputs to the Tape 2 output of the
amp (to record the sound from the amp onto VHS tape), I hear distortion
when playing back any source (CD, DVD player etc.). When I disconnect
the cable from the Tape 2 out, the sound is clear again.

What would cause this?

Could it have done any damage to the integrated amplifier?

Thanks.

I'd guess a ground loop. You could try connecting the two with a Ground
Loop Isolator. Radio Shack in the US sells one with RCA inputs and outputs.

Doubt it.

There are two problems. Most preamps do not have buffered outputs,
they simply divide the signal between as many devices that are
connected. Some equipment when unpowered, suck a lot
of current from the driving source, as when they use fet input switches.

I assume the devices are powered up. I do not know the specific NAD
circuit. I can only suggest that you may need another preamp, mixer, or
basically a buffer. is there any other device you have like a tape deck
that you can also try?

Now that you mention it, whichever VCR I had connected was always
turned off when I noticed the distortion.

Getting it to work is not really important at all, I was just concerned
that my shiny new integrated amp might be damaged.

Thanks for putting my mind at ease :-)
