    The SSVC4 is low-profile table top volume controls with individual A/B input selectors for each listening zone. The SVC300, a 300 watt autoformer volume control is utilized in each SSVC for uncompromised sound quality and performance. The screw down terminals to 14 gauge cable. The SSVC's feature 16 gauge steel construction with our durable black wrinkle powder coating and gray silk-screening. Compatible with all high-power amps up to 300W, the front-mounted master A/B switch allows you to toggle between two audio sources; for instance, switch from music streamed from your tablet or receiver with just a push of a button. 

    • Dual source speaker selector that distributes audio from a high current amplifier to up to six pairs of speakers or six separate zones
    • Includes individual volume control knobs to raise or lower the volume of each listening zone
    • Front-mounted master A/B switch lets you turn sources either on or off
    • Play one pair, a combination of pairs, or all four pairs simultaneously and adjust the volume to suit each zone
    • Impedance protection allows a single amplifier to safely power several pairs of speakers
    • Autoformer-based operates more efficiently than resistor-based selectors
    • Compact table top design or fits inside cabinets and equipment racks
    • Four individual zone on/off slotted buttons for easy labeling
    • Removable input/output connectors provide hassle-free hook-up
    • Compatible with all high-current amplifiers up to 300W

    • High quality metal construction
    Impedance-Matching Protection Safeguards Amplifiers
    To help protect expensive audio equipment, this 4-zone high-power speaker selector includes impedance-matching frequency protection circuitry that reduces subsonic signals so you can safely drive multiple pairs of speakers without going below the amp's impedance ratings which can cause it to overheat or shut down.

    What's on your mind?

    Steve • 12/17/2019, 2:17:43 PM Can this unit handle 4 ohm speakers? I have 2 pair 8 ohm and one 4 ohm.
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Steve, Unfortunately, this speaker selector is intended for 8-ohm speakers only. CL/MA 1289
    Dan • 12/17/2019, 2:17:43 PM Connection options to be sure I understand. My receiver has an A/B selector. Please confirm that I can connect this unit to my B speakers coming out of the receiver as 14 gauge speaker wire. The SSVC4 can split this signal into 2 or 4 zones with separate volume controls. If that sounds correct. Given this set up, will I be able to turn my amp volume down (my A speakers) and still crank up my B speakers much louder? Thanks for your help!
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Dan, All of our speaker selectors will accept 14 gauge wire. What you're trying to do may be determined by what your receiver can do. Does it allow separate volume control for A and B? I am assuming it does not. Our volume controls are passive devices that allow you to turn down the volume; they do not amplify a signal. You might consider using our SVC300 volume control on the A speakers that you want to turn down. If you tell me more about your application, I can make a more detailed recommendation by knowing more about your system. CL/MA 1294
    Dennis Maxwell • 12/17/2019, 2:17:43 PM How do you remove the speaker connector plugs? The instruction page refers to a "captive screw" on each side of the connector. I'm not finding that.
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Dennis, The A/B input plug and also Zone1/2 and Zone 3/4 connectors are removable. They are not attached, but the connection is fairly tight. I find pulling on one side then the other while applying constant pressure works best. It is literally just pushed in. Youll find that when it is removed, it is easier to terminate the wires because you have much better leverage. TL/MA 1318
    Edwin • 12/17/2019, 2:17:43 PM If I want the remote speakers to be louder than the signal from the main reciever, can I put a secondary stereo amplifier on the line into the ssvc4 and, if so, do you have a recommendation for such an amplifier?
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Edwin, We recommend the AMP200. With this amp, you can connect your receiver as a source via RCA cables and let it drive your four zones while the receiver remains the source. CL/MA 1330
    Brian • 12/17/2019, 2:17:43 PM If I supply this device with 100 W and run 4 pairs of speakers from it the max. power to each pair will be 25W? Or is 'impedance matching' allowing 100W to each pair.?
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Brian, Well need more information to help you. What component are you using for the 100 watts? Will you use the unused channels of a 7.1 Audio/Video Receiver or a dedicated power amplifier like our AMP120 or High Current Amplifier like the AMP200? The SSVC4 comes from the factory with the internal jumpers set at 2X so it is designed to have a higher output, especially when used in conjunction with our AMP200. The jumpers need to be set to 4x or 8x when used with our AMP120 or with most Audio/Video receivers. With a little information, we can be more helpful. TL/MA - 1405
