Wired Home CSVC50 Impedance Matching Rotary Speaker Volume Control 50W
Wired Home CSVC50 Impedance Matching Rotary Speaker Volume Control 50W is rated 4.32 out of 5 by 25.
Rated 4 out of 5 by from CSVC50 speaker volume controlWill not fit in a standard metal conduit box. They are too deep. Also the labeling on the amp in/spkr out connectors is backwards. Operation is good, also the impedance protection with multiple speakers is a nice feature.

Rated 5 out of 5 by from Lots of electronics packed in tightFirst off, I will be buying and using more of these in the near future. They work great.BUT, I installed two of them in the same box using 14g wire and it got very crowded. The connectors were IMHO too small and close together, resulting in <1/8" btwn wires as they exited the connectors.With both units inserted into a 2 gang box, the wires inserted into the right hand unit were forced against the sharp soldered circuitry of the left unit. My concern is whether the solder will perforate the wire coating and compromise the circuit. I'll probably insert a spacer (cardboard) just to be safe.Again, I will be buying these again. They work great

Rated 3 out of 5 by from will not fit wired in a retrofit box!Found the only way to put in a retrofit box is to take wire lugs off, put the unit in the box before you put it in the wall.Wire it then install the box in the wall.

Rated 5 out of 5 by from excellent product for the priceI've installed many of these controls for my customers and have 100% satisfaction with appearance and operation. They are just as good as Russound for much less $$. Operation is smooth, terminal blocks hold tight to 16ga wire, fit is perfect, colors are right, and the hardware is #2 Phillips. I hate flat head hardware.

Rated 4 out of 5 by from works fineIt is a basic product which works well. Kit contained 3 colors of knobs and face plates and all necessary hardware. I am personally not a fan of Phoenix connectors, but all brands seem to use them.

Wired Home CSVC50 Impedance Matching Rotary Speaker Volume Control 50W

I recently bought a volume switch csvc50. It does not shut the volume completely off, you can still hear it even when its all the way down. This is the 2nd of these switches, the other one works fine and they are hooked to the same system.

Asked by: Bobfisher
I am sorry that you have had trouble. I would double check the jumper settings on both controls to make sure they are set the same. If they are, then you may have a defective unit. Just contact us at tech@parts and we will be happy to look into your options.

Jumper question follow up

Just to follow up, the jumper on the speaker/output side moves to x2 and the jumper on the amplifier/input side stays at x1 or moves to x2 also? Thanks.
Asked by: MRMatt
There is one jumper per channel so they both need to be on the same setting.

Jumper question

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.
Asked by: MRMatt
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.

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.
Asked by: MrBaja
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.

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.
Asked by: fishging
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?
Asked by: CruelSun
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.
