Lifetime Tech Support

The ISS4 High Power Speaker Selector is an easy and effective way to distribute music to up to four listening zones (four pairs of speakers) and play any pair, a combination of pairs, or all pairs simultaneously. Easy to connect with a low-profile design that easily fits into a cabinet or equipment rack.n choose. Front-panel push buttons let you quickly turn each pair of speakers on or off independently, and die cut labels fit within the recessed area on the buttons for easy labeling of each zone. A passive device that does not require power to operate, the ISS4 also includes impedance-matching circuitry so you can safely drive all four pairs at once without damaging your receiver or amp. Designed with quality in mind, the ISS4 is constructed of 16-gauge steel with a durable black powder coating and gray silk-screening. 

Features
  • Distributes audio from a receiver or amp to multiple pairs of speakers
  • Send one signal to up to four pairs of speakers in different listening zones
  • Impedance protection allows a single amplifier to safely power multiple speakers
  • Removable input/output connectors allow easy cable termination
  • Includes on/off switches for each zone
  • Low profile with beautiful black brushed aluminum finish
  • Works with any amplifier 
  • Includes a two-year warranty
Upgraded Input/Output Connectors
The ISS4 is easy to install (even for non-technical types) and accepts up to 14-gauge cable. The European-style input/output connectors are removable, which gives you better leverage when terminating cable than traditional spring-loaded terminals. This speaker selector takes either four or two conductor speaker wire stripped at the ends that are inserted into the screw-down input/output terminals for a tight fit to ensure the best signal transmission and sound quality possible. 

Protecting Valuable Audio Equipment with Impedance Protection 
When connecting multiple speakers to a receiver or amplifier, you need to stay above the amp's minimum load requirements. Going below the impedance rating can overheat or even damage expensive equipment. The ISS4 includes selectable impedance matching protection circuitry that allows a single amplifier to safely power several pairs of speakers. The speaker selector handles 140 watts per channel total input power without the manual protection engaged and 70 watts per channel with the protection engaged.

Adam • 12/17/2019, 2:17:43 PM Does this speaker selector have separate left and right grounds for each speaker pair?
Customer Service • 12/17/2019, 2:17:43 PM
Hi Adam, Yes - you will have a left +/- and right +/- both for the input and each zone output, allowing you to run stereo in and out. It also has an impedance protection option in case you aren't running impedance matching volume controls and/or your amp can't handle anything but an 8ohm load. -BM 2381
Mike • 12/17/2019, 2:17:43 PM I am confused by the Circuit Protection button on this unit. The speakers are louder when it is pressed in, as though that is the Off position that allows full power, and when depressed (not pushed in), the speakers are softer, regardless of how many channels are being driven. Can you check with the engineers on this and verify which position enables the impedenece matching protection circuit and reduces power to 70 watts? Another questioner mentioned his unit started smoking when he depressed the circuit, thinking that turned it off, but that doesn't make sense since it would more likely overheat when pushing too much power above 70 watts, and his amp was shutting off when the circuit was pushed in, indicating too much draw or too low of ohms for the amp. This needs to be clarified and corrected in the documentation or risk potential damage to both the unit and other electronics.
Customer Service • 12/17/2019, 2:17:43 PM
Hi Mike, Thank you for bringing this to our attention. As you may know, the impedance protection helps the amp to see a more stable load, but that all depends on how many speakers are on the load and what the amp can handle. If the amp is rated to run power at 4ohms, it would make sense that you are receiving more power when the protection is enabled, if the load it is showing is 8ohms. There are several configurations that would alter the volume of the speakers, but it is appreciated that you pointed out that our website states only a specific outcome. We will work on updating that. Thank you! -BM 2453
Nick • 12/17/2019, 2:17:43 PM Does this unit have separate volume controls for each pair of speakers? Or are all the pairs of speakers on the same (single) master volume control and this unit just allows you to turn them either ON or OFF. I want to be able to individually control each pair of speakers, and nowhere can I see whether this unit allows that. I can't see any volume knobs. If this unit DOESN'T allow that, which unit DOES?
Customer Service • 12/17/2019, 2:17:43 PM
Hi Nick, With the OSD-ISS4, this allows you to turn on or off each individual pairs of speakers but not control the volume for each individual pair. What you are looking for is the OSD-SSVC4. This will allow you to control the volume of up to 4 separate pair of speakers. CS 2468
Tom • 12/17/2019, 2:17:43 PM I have a denon avr 591 surround which I currently have running a 5.1 boston surround set. I would like to take the back two channels and hook them up to this unit so I can send power out to 4 outdoor speakers. Is this going to work? Thanks.
Customer Service • 12/17/2019, 2:17:43 PM
Hi Tom, It all depends on whether your Denon receiver can handle anything less than an 8ohm load. When you run 2 pairs of speakers you will drop it to a 4ohm load and if that receiver can't handle it, you could cause some damage. I would advise you to speak with someone at Denon to see if that is safe to do with their receiver, If not, you can run an external amp from the receiver to run the outdoor speakers. Check out our AMP120. -BM 2511
Paul • 12/17/2019, 2:17:43 PM I have a samsung surround system that runs on 3ohms. I have just added a Polk psw505 that runs on 8 ohms. I am buying this selector to run speakers to my patio but would the impendence protection on this selector protect my subwoofer as well? I am planning the purchase of a new receiver to replace the samsung unit in the next few months but am looking for added protection until then.thanks for any help you could provide.
Customer Service • 12/17/2019, 2:17:43 PM
Hi Paul, Thanks for the question. The thing about running a powered subwoofer like that via speaker level inputs as opposed to line level inputs (RCA), is you won't get nearly as good quality sound. Theoretically you would probably get a signal through the selector and over to the subwoofer, but on top of the already degraded quality of the speaker level, you're adding an extra component (ISS4) between the source/sub which would further degrade the quality of the signal going to the subwoofer. Also, you may want to double check with Samsung to see if you can run a speaker selector safely from that receiver. -BM 2601
