Default Additional Speakers

10 metres is a short cable length for line-level signals.

I've not tried this, but I think you should be able to test the effect of
the vable by using it to connect your receiver's tape out to tape in. Then
pressing the tape monitor button will let you assess any difference the
cable is making.

You may even be able to conduct a listening test, with someone else
manipulating the button, and you trying to tell what state it's in.

I've got an AV Receiver in my living room, and want to feed some extra
speakers (stereo only) in the kitchen. I want to be able to mute the
sound in the living room if I want, whilst still hearing the sound in the
kitchen, and vice versa. The cable run will have to be about 10 metres.

The AV Receiver only has one set of speaker outputs. However, it does
have pre-outs, as well as tape loop phono outputs and digital outputs,
both optical and electrical.

What's the best way to connect extra speakers? I assume that if I use the
pre-outs, the sound will mute in the kitchen if I mute it in the living
room. The digital outputs only work if the input is also digital, which
isn't ideal but I might live with it if it means thinner cable and better
sound. This just leaves the tape output, but I'm worried about the cable
lenght, and hiding a thick cable might prove difficult. Are there any
other possibilities I've missed?

Presumably I would need some kind of amp or powered speakers to make use
of any of these outputs. Can anyone recommend a simple small amp or
powered speakers that can handle digital input?

Thanks.

Probably. But I would check the source o/p impedance and cable capacitance
before being sure of this. In general, domestic kit tends to be used with
shorter runs. Also check for any hum problems, particularly when the source
are destination are being powered by different mains sockets in different
rooms.

If the 'tape' outputs are unbufferred the impedance may depend on the
signal source driving the amp as well. And if the cable capacitance is too
high, this may affect the results when listening via the 'source' amp.


Slainte,

Jim
