Wired Home SS4 Speaker Selector Impedance Matching 1 In 4 Out

The SS4 is a low-profile speaker selector that allows you to distribute a stereo speaker-level (amplified) signal to multiple listening zones. These speaker selectors feature a manually activated impedance protection circuit. The protection switch can be turned ON to prevent the impedance to your amplifier from dropping below 5 ohms, regardless of the number and impedance ratings of your speakers. The protection switch can be turned OFF when used as part of a system incorporating impedance matching volume controls, allowing you to get the most out of your amplifier.

The terminals on the rear of the speaker selector will accommodate up to 14 gauge cable; sufficient for cable runs exceeding 100 feet. For shorter distances, 16 ~ 18 gauge cable will suffice. For in-wall installations, we recommend using CL-2 or CL-3 rated cable for compliance with local building codes. If unsure, contact you local building inspector. When connecting a speaker and amplifier, it is important to maintain polarity; positive (+/red) to positive and negative (-/black) to negative. Be careful to maintain correct polarity between the amplifier, the speaker selector, the volume controls and the speakers. Power: 70 watts/channel impedance protection off, 140 watts/channel impedance protection on. Dimensions: 8-1/2" W x 2-1/8" H (with feet) x 5" D (including wire terminals and push buttons).

Rated 5 out of 5 by from Great ProductI bought this unit to replace a Radio Shack unit that died. Surprising heavy. Very good quality spring loaded connectors

Rated 5 out of 5 by from Dayton Speaker Audio SelectorGreat Speaker Selector. Excellent connectors. This unit replaced a Radio Shack unit that had connectors that were always loose and eventually failed. There are lots of units out there that use RCA connectors but as this is wired into the house I needed wire connectors. The unit is surprisingly heavy and well built. Works perfectly and the impedence selector will protect the stereo.

Rated 5 out of 5 by from It works as expected.I am a novice in this area, but this little box seems to do the trick for my garage system with multiple speakers.

Rated 5 out of 5 by from So Far, So GreatBought this selector to replace one that was malfunctioning badly. Installed it about a month ago and find it working just right for me. Small, fits in the space and does not cause any distortion that I can tell.

Rated 3 out of 5 by from Good, but not great.Purchased one of these Dayton selectors to be able to control two sets of speakers; one set indoor and the other outdoor. This is being used with a Lepai 20wx2 amplifier powering a set of Sony bookshelf indoor and a set of Dayton weather resistant speakers outdoor. The setup is great for moderate listening levels... actually better than I expected. However when the time came to just listening to the indoor set, deactivating the outdoor on the selector, they were still music coming through one channel outdoor. After pressing different button configurations; finally just switched from speaker set 2 to speaker set 4. After this switch it worked as desired; thankfully just need it to control two sets and not four.

Wired Home SS4 Speaker Selector Impedance Matching 1 In 4 Out

can any one tell me how to safely hook up my SS4 speaker selector Wired home or Dayton they have an input output and 4 channels i may be nuts but why should  there be an  output along  with the 4 output channel ?? thanks  for your help

Asked by: lacguy
The output is simply a pass-through connection since the SS4 occupies the outputs from your receiver for the connections. The other four outputs are the switched outputs that have selectable impedance matching option.

So would there be any problem running two pair of small ADS L200C speakers through this switch? Amp is 115 WPC Denon PMA-1315R.  Can I run them off the B speaker output of the amp and still keep my AR-3a's running off the A output? 

Asked by: JBaudiophile
Usually when a receiver has A and B outputs and both are used, the impedance is combined for both. The receiver will have to safely handle a 4 ohm load in order for it to be connected this way.

Can I damage my receiver by running too many pairs of speakers at once? I am thinking of using the SS4 with an older 45wpc receiver to switch between remote speakers. If I accidentally run 3 or 4 pairs at once can it damage the receiver?

Asked by: Luddite
This is designed to match the impedance and maintain a safe 8 ohm load assuming 8 ohm speakers are hooked up to it.

Is the SS4 Selector Reversable, i.e. Use As Amplifier Selector?

I want to share a single powered subwoofer between two audio systems. In this configuration I would attach Amp 1 speaker out to SS4 Output 1 and Amp 2 speaker out to SS4 Output 2. Subwoofer attach to SS4 Input. Route desired amp to subwoofer by selecting 1 or 2 on SS4.Depending on the electronics (e.g. only switches and resistors) the SS4 may handle the signal in reverse. Can anyone speak to the SS4 electronics? Or has anyone tried this already with the SS4?I understand the risks of driving two amps into the SW at once.
Asked by: Nate2622
Unfortunately no, this is only functional in one direction.

Can this be used to turn on zone 1, then turn off zone 1 and turn on zone 2?

I have 2 pairs of 4 ohm speakers, and my little bookshelf unit can't handle that I don't think - at least both at the same time - one at a time, it can. Sets of speakers to be placed in nearby areas and not used together, at one time. Receiver is rated 40w/ch and came with one set of the 4 ohm speakers. Would anything be different if I replaced one set of 4 ohm speakers with 6-8 ohm speakers instead?
Asked by: JMG1
The best thing to do is get a bigger amp/receiver these days amps put out 100 watts p/ch is standard. 40watts is not going to cut it, also when you have 4 speakers that are all low in ohms, some amps/rec don't like all that low ohm loads, so looking for a bigger amp is better you could do damage to the amp if you keep using it in this way...PE has a wide range of amps/receivers...

Max power?

So this lists "140 watts/channel impedance protection on". Is this output on each channel? So this is capable of distributing power to 4 pairs of speakers at 140 watts/channel? (assuming the amp is stable at low ohm loads and is capable of at least 600 watt/ch)
Asked by: Charles
Depending on the impedance protection setting, it looks like either 70W or 140W per channel channel (NOT per speaker) . Driving 4 pair of identical speakers simultaneously, that works out to 35W per speaker, minus a little circuit loss, w/ protection on.
