Multi-room speaker set up

[Walnut]

Hi,

I'm looking for some advice, I have an AV receiver (Sony DH790) (6-16 ohm), 145w and I have 2 sets of bookshelf speakers, Q Acoustics 3020i (6 ohm 50-75W) and Klipsch R-40M (8 ohm 50w ). I would like to put the speakers in different rooms being able to play the same source both together or just one location. I had looked at a speaker switch from QED ( SS40) which has 4 outputs, but it would wire the speakers in parallel giving a less than 4 ohm impedance, much lower than the 6ohm rating of the receiver.
Is there a series switch someone could recommend which would work ? or some other set up advice?

thanks

Have a look through the manual on page 22. I had a quick look at the back panel of the AVR and I noticed that the main L+R speaker terminals say FRONT A and the Surround Back speaker terminals say (FRONT B / BI-AMP). Page 22 shows the FRONT B speakers in another room. You can use the speaker button on the front of the AVR to select SPKA, SPKB or SPK A+B. You will also need to program the speaker connections in the setup menu so that the AVR knows that they are speaker B and not surround back.

Hi Eppie,

thanks for your reply, you make a good point and something I had forgotten as actually I want 3 speakers not 2 switched, as I have surround speakers to go into the AVR as well (I have 5.1 speakers from an old surround home cinema device), I think I had thought the 5.1 would all slot into the clamp fittings and the other speakers (bookshelf) into the banana plugs (FL & FR).
I already have the issue that the surround satellite speakers are only 3 ohms, I could get around that by adding two additional satellite speakers in series to make them a safe impedance.

(I should really check my AVR and all my speakers to give a proper picture and thus question of help creating the set up).

You can not wire speakers in series that are not the same. That will cause a complex load. Speakers are not resistive loads, and strict resistive load addition does not apply. Speakers are reactive loads and not resistive loads.

What you really require is a distribution amp.

First, stop trying to provide a max wattage or nominal impedance as particularly important....they're not the greatest guidelines. Make and model are good enough to go on if you don't provide more technical details like measurements....

Some avrs are better for zones or A/B setups, didn't look at your manual but it should explain well what your options are.
