speaker selector?

[jw23]

I have a yamaha v765 receiver and I am looking to hook up 4 outdoor speakers to zone 2. From what I have read so far, hooking up 4 speakers onto 2 channels may create an impedence problem and that I should get a speaker selector with impedence matching. Is this correct? Is there a better way to do this?
Would this one work?

Will you be using a volume control for these or the control on Zone 2? If you leave the Zone 2 control set to -0dB, you won't have to deal with a "no volume, but the outside volume control is wide open" issue. An impedance matching volume control can handle 2 dual voice coil speakers or 4 normal speakers. If you get a muting volume control, like a Niles or Proficient, it won't go on when the system turns on, only when the muting button is pressed- this keeps you from disturbing neighbors.

If you plan to place the speakers far apart and need to adjust the volume for each separately, it would be better to use something like an SSVC4.

i hadnt planned on using separate volume controls for the outdoor speakers. i guess i was planning on using the master volume control. i mainly want to make sure i dont overload my amp. i will be hooking up 4 speakers through the 2 channels on the zone 2 of the yamaha v765. i can get volume controls if it would be best for the amp (or for other reasons)
thanks for the reply and anything to point me in the right direction is appreciated

If you leave the Zone 2 at one level, you'll never have to deal with the "I don't hear much" routine, caused by one person trying to turn it up near the speakers and another person having turned it down at the receiver, a la Clark Griswold, when he was trying to get the Christmas lights to stay on.

If the receiver will be close enough to where the other speaker zone is, the selector/volume control can be placed there. If the speakers are similar in volume with equal power (similar sensitivity), you can use a simple impedance matching switcher, like the one in the link.

If they need to be adjusted separately, this will work-

Remember- the second one has four volume controls inside and you can't just use a generic "volume control", like they sell at a parts store. An L-Pad can be used if you're filtering the lows out first, but it still isn't the right way to maintain the correct impedance.

thanks for all the advice.
if i just want to control volume from the receiver, would this speaker selector

work to keep impedance at safe levels for the receiver? it looks very similar to the one you posted.

Similar, but with the addition of source switching for each pair.

There aren't that many companies who actually make these and they'll put whatever name someone wants on it but the component quality is important. Some of the sliding volume controls have a tendency to short out internally and if it's connected to a receiver, that channel will go away. If they're connected to a piece for maintaining correct impedance, that will be damaged. If the switch box or volume control uses resistors instead of auto-formers, it wastes a lot more energy and that means the resistors get hot.
