    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.

    • 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

    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?

    Scott • 12/17/2019, 2:17:43 PM I have 3 pairs of 8-ohm speakers and one pair of 4-ohm speakers. Will the SSVC4 properly match the different impedance and protect my source amplifiers? I read another post that indicated there are "internal jumpers" that are set at 2x. Would I have to take apart the speaker selector in order to change jumpers? If so, how would I set them so my system is properly balanced?
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Scott, Based upon your application, change the settings to 4x internally on all four of the zones. Technically, you would consider a pair of 4-ohm speakers as two 8-ohm speakers so you would have 5 speakers (adding three 8-ohm speakers to the 4-ohm speaker considered two more 8-ohm or five total). Therefore, go to 8x on the safe side. You also need to factor in the receiver or amplifier. An 8x setting would be advised if you are using an amplifier like our AMP120 or connecting to a basic audio/video receiver's second room option to do multiple rooms. A 4x setting would be advised on a high current amplifier like the AMP200 or a top of the line audio/video receiver. Let us know more about what you plan to connect to the SSVC4. TL/MA 1633
    Ryan • 12/17/2019, 2:17:43 PM I am curious about using this with my Denon Avr 2313. I'd like to switch different speakers for different sound modes, and may want to double some of them. I.e. If I want two wide speakers and four rear speakers or vice versa. I was just curious if this is healthy for my amp switching around the two surround zones among the 6 speakers I have mounted for back, and doubling the surround channels into two speaker sets. My speakers are all Jbl satellites rated at 100 watts and my receiver is rated at 105 per discreet channel. And please tell me about "jumpers" that I have read about from other questions here and how it will effect my set-up.

    Hi Ryan, Yes, the SSVC4 speaker selector volume control will let you separate the zones. Be sure to remove the cover of the SSVC4 and manually change the jumpers to a 4x setting. Then replace the cover. CL/MB/MA 1639
    Scott • 12/17/2019, 2:17:43 PM How do you change the jumpers on the SSVC4 unit?
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Scott, Remove the cover and you will find the jumper behind each internal volume control. You will need to set each jumper to the same setting.The SSVC4 comes with the jumpers set at 2x (pin 2-3). To change to 4x, you will need to slide the jumper over pin 4 and 5. TL/MA 1663
    joe stanger • 12/17/2019, 2:17:43 PM I have a game room as my primary sound hub and now I would like to install speakers around the house . I would like to use the receiver that runs the "sound hub" but I would still like to use the sub. How can I still make the sub part of the system. I guess if the receiver is its own zone then it will work, but not sure if the receiver is totally isolated now with a SS. So this system could actually be a 5 zone system with a 4 zone SS??
    Customer Service • 12/17/2019, 2:17:43 PM
    HI Joe, Well need more information from you. What is the receiver you are using? Is it a 2-channel receiver or an AV receiver with a second room output? What kind of subwoofer will do you have and does it have a speaker level input as an option? Let us know so we can answer you more thoroughly. You can also upload a diagram of your layout in the Learning Center toward the top, right of the website. TL/MA #1732
    Greg K • 12/17/2019, 2:17:43 PM I have an Onkyo NR609 running a 5.1 surround indoors. I am adding 2 pairs of Bose outdoor speakers outside and a pair of your word rock speakers in a landscape area. I have also purchased your 200 Amp, the DSM 4, and this SSVC4. Could you let me know where to connect to my Onkyo using Zone 2, I presume to the Amp 200, etc,etc.....I believe I have everything needed?
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Greg, You can either use an RCA output from your receiver into the line 2 input of the AMP200 or the powered Zone 2 from your ONKYO into the AMP200's "Speaker In." We offer the AMP200 high current amp with our 4-zone kit; however, you have two, 4-zone speaker selectors? Typically, only one would connect to the AMP200 by coming out of the Speaker A left and into the Input of the speaker selector left and right (as if it was a pair of speakers). For 8 zones, (16 speakers), consider our larger AMP300 if you want to run both speaker selectors. CL/MA 1757
