I can send you a copy of my photocopy, unless some nice person in Salisbury can send us both hard copies. Having said that, it's not terribly informative in any event.

To answer your questions.

The volume knobs on the AV1 control rear volume only.

It needs to run off a spare output socket of the power supply for the preamp (the HiCap or SuperCap powering the 72 or 82, to take your example), so I don't suppose it would work in a non-Naim system. It then processes signal to the rear speakers without any further amplification necessary. The power supply is built in.

Even at full volume (which you wouldn't use), the sound it produces is much quieter than the front channel sound. It's rather subtle in operation, in that you only tend to spot what it's doing when you mute its output.

Hope this helps.

Now, I haven't actually conneted my AV1 up for a few months so I could be wrong....but....I don't recall any speaker outputs on the back of mine, and I'm sure I used to connect it up to my JR149s via my spare 250....

Are there different versions of AV1...or am I going round the twist?

Sorry, I was forgetting about the NAP250 sitting between the AV1 and the rear speakers, so I'm the one going round the twist!!

Thank you all for the info.

This raises a further question -- Does the AV1 do anything to the front channels, or is the front channel output DIN just a pass-through to the front-channel amp?

Graham-I would like to get a copy of your copy. My address is:

Thanks again,

PS I know, "What's an English surname doing on St. Patricks Drive?" It has to do with California property values....

There are two stereo rear-channel output DINs, but no front-channel output (assumed to be at your HICAP / SUPERCAP etc.).

In other words, no, the AV1 stays completely out of the front-channel (stereo) signal path.

Good point David,It's making more sense now.

I am looking at the back panel. There is the 4 pin plug marked Audio In. There are two 4 pin plugs, jointly marked Audio Out, with no mention of front or rear, each having pins for Ch 1 and Ch 2.

Are the two outputs redundant, in the event you are using mono amps or desire two pairs of ambience speakers?
