    What's on your mind?

    Danette Larson • 12/17/2019, 2:17:43 PM I have a Yamaha RX-V663 - 7-channel Receiver. I currently use the iPod Dock with Polk Audio RTiA7 8ohm speakers in the front speakers A port in my house. I would like to hook up 1 - 3 sets of Yamaha AW390 speakers (6ohm) on my covered porch either at the same time (A&B) or just A or B by themselves. First of all from what I am reading in the receiver manual is that if i want to run ports A & B front speakers at the same time I will have to have all 8ohm speakers and can only run 1 additional pair. Can i use this speaker selector for what I want to do?

    Hi Danette, You have the right idea about what the speaker selector does, but your receiver isn't built to handle that type of load. You will need an external amp to run from your receiver to this selector in order to supply enough wattage and handle a 2-4ohm load. Check out our AMP200! BM 2745
    Stephen • 12/17/2019, 2:17:43 PM Hello, I am trying to install speakers in a small restaurant. I have decided that I will have 4 zones. For speakers I am looking at buying (12) - 6.5" ,8ohm 50w RMS / 100w max in ceiling speakers. I have a Onkyo amplifier model M-501 rated at 150w x 2 @ 8ohms. I was planning to use a regular home receiver to drive 4 speakers in the bathrooms and then use the Onkyo amp to drive the other 8 speakers. To keep the impedance in check I planned to wire up sets of speakers in series/parallel to stay at 8ohms. Their would be (8) speakers running off the Onkyo amp. So I would control the volume of the bathroom zones by using the receiver as the master control and then set the levels of the other zones by using the SSVC4. This way when I set the level on each zone on the SSVC4 I can then use the receiver to manage total volume across the building. Also, I do not want to have to continuously go behind employees and monitor them adjusting volume levels at their desire. So, do you think Onkyo amp will be enough to drive (8) 6.5" 8ohm speakers? And will my wiring /set up plan work with the SSVC4? I am on a tight budget so I am re purposing some home equipment along with the purchase of a selector like your SSVC4. In time I plan to upgrade to a more powerful amplifier and have looked at your selection. I just need this set up to work in the mean time so I can get finished and open. I would greatly appreciate your thoughts on my plan. Thank you

    Hi Stephen, It gets a bit tricky when trying to run multi-zone audio with a standard 8 ohm receiver. When running multiple pairs of speakers, the load drops from 8ohms to 4ohms and below. If you run an impedance matching device such as the SSVC4, that will help, but it won't necessarily send a perfectly stable load back to the amp/receiver. If the amp/receiver is only built for 8ohm loads and it sees a different ohm load, this can cause some issues and damage your components. That's not to say your amp/receiver won't work, but you would have to be cautious and maybe want to contact Onkyo to see what they have to say. If your amp is not powerful enough, you can always run our AMP200 with the SSVC4. Thanks!
    Holger F • 12/17/2019, 2:17:43 PM Hi, At the heart of my home AV system I run a Denon AVR3802 receiver. It, however, can only source- and volume-control 2 independent zones/rooms, which does not meet my needs of wanting to control 4 independent outdoor listening areas in addition to my living room. I recently inherited a NuVo NV-E6DMS six source, six zone amplifier, however do not have or want to utilize the in-wall individual zone controller keypads this multi-zone amplifier typically is set up with. Is there such a thing as a centralized multi-zone volume controller that would allow me to feed a single source signal to the Novo amplifier and then have that NuVo amplifier send up to 6 zone audio signals to a centralized volume controller which, in turn, would take the individual audio signals, modulate them individually to the desired audio level (incl. "off") and then send the modulated signal to 8-ohm speakers in the various outdoor listening zones I have? Thanks!
    Customer Service • 12/17/2019, 2:17:43 PM
    HI Holger: First question, does the NUVO NV-E6DMS work? If so it would be ideal for your setup but you will need the control pads to make it work the best. You can find the control Pads on eBay or contact NUVO directly. The unit is probably 6 to 10 years old but still should handle your needs. You would have the option to either utilize the key pads in each room if you have the ability to run Cat5 to each location or you can create a master control panel with all the control panels grouped together in your central location. The NUVO also gives you the ability to add up to 5 additional sources since it has a built in 6 source pre amp This is where you would connect your Denon second zone output. The control pads would allow you to select the different sources attached to the NUVO Amp/Preamp as well as control the volume, bass and treble. I believe there is also a party mode where you can control all your zones from a single control pad. I would love to recommend the SSVC4 but it is only dual source and you would not be taking advantage of all the features of the NUVO. TL/3090
    Fredric • 12/17/2019, 2:17:43 PM I have a spare 7.1 receiver which has Spotify Connect and Airplay receiving-capabilities. I am considering using this in order to power onwall and in-ceiling speakers I have in the lounge (2 speakers), the bathroom (2 speakers), kitchen (2 speakers) and bedroom (1 speaker). I was going to buy a selector but I have experimented some with the 7 channel stereo which seems to send L/R to front, rear, side and center speaker (which gets l+r). Would an speaker selector such as the SSVC4 add something to my install? Also is it advisable to put speaker level volume controls between the receiver and speakers or will this disturb the receiver? Down the road I am aiming for a proper multi-room setup but I am waiting for a multi channel amp with spotify connect and airplay capabilities as well as good app control for controlling the zones (most of which my 7 ch receiver has except the individual volume control).
    Customer Service • 12/17/2019, 2:17:43 PM
    HI Fredric: The SSVC4 would be perfect for your application. The internal volume controls will control the impedance matching needed when connecting more than two pair of speakers to your AVR (Receiver). An added bonus would be if your receiver featured a second zone output. If so this could be connected to the second source input of the SSVC4 (Source B). The L-R from the AVR output would go to Source Input A. This would allow you to play two sources at once at the same time. The speaker selector features a A/B switch for each of the four zones so you could be listening to source A on Zone 1 and 3 while listening to Source B on zone 2 and 4. Check your owners manual to see if it features the second zone out. Note if you do not have the owners manual you can find almost any Owners manual on line. One other point: The SSVC4 also features an on/off switch which you should use when not listening to a particular zone. Turning the Volume Control all the way counterclockwise does not turn the zone off. Good luck, TL/3092
    mike • 12/17/2019, 2:17:43 PM I am interested in this product. The receiver I want to connect it to has an audio output that accepts a plug in. Do you sell a cable that has a plug in on one side, and open wire on the other to screw in to ssvc4? Or do I have to cut the connector off of one end and strip it back?
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Mike, When you say a plug in, do you mean RCA? This unit is a passive device that needs to be run from an amplifier via speaker wire.
