Multi room from main system
Hi all. I am planning to run some speaker cable from my main system through to the kitchen via a speaker switch box. The speakers in the living room have a different impedance to those that will be used in the kitchen. Is this going to be problematic? My system is as follows...
Rega Brio r (50w per channel)
Living room speakers Rega rs1 (sensitivity 90db, impedance 8ohm)
Kitchen speakers wharfedale diamond 9.0 (sensitivity 86db, impedance 6ohm)
Thanks,
Phil

Simple answer no.
Complex answer, as with any amplifier and multiple speakers, is not to go below the rated output impedance capability of the amp.
The Brio has a specified rating at 4 ohms, if you connected the two sets of speakers in parallel to the amplifier output (one across the other) the amplifier would see 3.4 ohms.
This would be OK providing you didn't cane it. As an example if you connected two sets of 4 ohm speakers in parallel this would be a load of 2 ohms, definitely a no-no.
I have multiple pairs of speakers around the property (including outside) so the switch box I use connects them in a series/parallel way so that the impedance doesn't drop too much.

Oh my god! There's nothing wrong with the bidet is there?
“Nothing discloses real character like the use of power. It is easy for the weak to be gentle. Most people can bear adversity. But if you wish to know what a man really is, give him power. This is the supreme test. It is the glory of Lincoln that, having almost absolute power, he never abused it, except on the side of mercy".
“You see these dictators on their pedestals, surrounded by the bayonets of their soldiers and the truncheons of their police ... yet in their hearts there is unspoken fear. They are afraid of words and thoughts: words spoken abroad, thoughts stirring at home -- all the more powerful because forbidden -- terrify them. A little mouse of thought appears in the room, and even the mightiest potentates are thrown into panic.”

Thanks, Alan. I will only very rarely have both sets of speakers running at the same time so I think I will be fine. It might even be an excuse to buy another set of speakers!
