Wired Home CSVC50 Impedance Matching Rotary Speaker Volume Control 50W
Single amp and 2 sets of speakers each with their own control
I want to feed 2 sets of speakers, each with their own volume control, with one amp. Will 2 of these devices wired in parallel maintain a 4 to 8 ohm impedance to the amplifier?
Yes. There is a jumper on the circuit board you can move to adjust the over all impedance the amp sees for 2, 4, 8 pairs of speakers for a total load of 4 or 8 ohms. The instruction sheet has a chart for how many speakers at what impedance they are for total impedance depending on the jumper position. I have run 4 to 8 pairs of speakers on an equal number of volume controls with one amp or receiver in several homes without any problems.

Can this volume control be connected to sub, then speakers?
I am installing this in my garage where I would like to run the following: Speaker wire from amp to volume control. Then, speaker wire from volume control out to sub. Then from sub - to speakers. Is this still possible keeping the impedance factor from damaging my receiver?
It is possible, but not recommended. If you do wire the system through one volume control, you will lose the control you'd have by running the subwoofer separately. You must not use any "loudness" or bass boost features from your amp or receiver, as this can potentially saturate the transformers in the volume control, and cause the volume control itself to produce audible sound.

How to set the jumpers?
I've had three of these installed, but I may have misread the instructions to begin with. Each Volume Control is connected to a pair of 8ohm speakers. My Stereo calls for 6-16ohms/speaker.Does that mean I should use the x4 Jumper?Having a hard time understanding the chart.
The number of volume controls determines where the jumper is set, so yes you want to use the x4 position with three volume controls.

can I use this after a 4 pair speaker selector/volume control
I have an AVR with a 130w zone2 output that I plan to connect to a 4 pair speaker selector that has volume control for each pair (Niles or Russound brand?). 2 or 3 of the selector outputs will be for outdoor speakers, the last for a pair of ceiling speakers for my kitchen. Can I use one of these controls in the room with the speakers wired after the 4 pair switch?
Yes. If you are only using one leave the jumper alone. If you are using one on each output from the selector than you want to turn the speaker protection "off" on the selector.

Another jumper setup question
I installed four of these (to three pair of Dayton in-ceiling and one pair of Dayton outdoor speakers) and connected them to the Dayton Audio SS4 Speaker Selector Impedance Matching 1 In 4 Out. My receiver "blew" after our first social gathering (after the guests left and the wife wanted to crank a few of her fave tunes). Before I purchase a new receiver, I thought I better check my setup and get advice from some experts.
With a setup like this, the speaker selector impedance protection needs to be off because the volume controls are doing this for you. The volume control jumpers need to be on "x4". Most standard receivers are not designed to handle a system like this. Even with impedance protection the impedance can drop below 6 ohms which is a huge load on a typical receiver which can cause failure. Your best bet is to find a receiver with preamp or second zone outputs and drive the whole house system with an external amplifier. Our Behringer A500 is a great choice for this.

I am currently installing my third CSVC50 volume control, and I'm confused about the jumper, etc. I run a single 120watt receiver through a SS4 speaker selector, with the protector off, and never run more than two sets of speakers at once. The two previous volume controls govern one set of speakers connected to the receivers A speakers and one set to the B speakers via the SS4. This third control will govern an in-ceiling stereo tweeters/single woofer via the SS4. If I never run more than two sets of speakers as configured, do I need to do something with the jumper, and what, and where is the jumper to begin with? Thanks.
You will want to have the two SS4 volume control jumpers on 2x, the single on channel A can stay on 1x as long as they are not all three used at the same time. They should be on 1x from the factory.
