    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. 

    • 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.

    What's on your mind?

    Don • 12/17/2019, 2:17:43 PM I have a Onkyo-8020 receiver. It has a speaker A and B button. I want to run two 8 ohm speakers and a 6 ohm pair. Is it safe to run the 8 ohm speakers on the "A" output and the 6 ohm speakers on the "B" output or can I should I use the speaker selector switch and run it off output "A"? Thank you.
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Don: The Onkyo claims to have all discrete components and High Current Audio section. Based upon that you should be able to connect the two 8 ohm speakers on speaker A and then the 6 ohm speaker on Speaker B. I would feel more comfortable if they all were 8 ohm. By adding a speaker selector by itself with out adding impedance matching Volume Controls would not be the answer. The ISS4 has internal protection that cuts the power handling in half. We try recommending Impedance matching Volume Controls because they do a better job of actually impedance matching to the Receiver. The one thing about the Japanese Amplifiers is they usually have pretty good protection that kicks in a relay shutting it down rather than allowing any damage. I would try wiring as you said and try playing both A & B at the same time at moderate levels and then see if the Receiver gets hot to the touch or maybe shuts off. Note: Checkout page 13 in the owners manual, setting up the speaker impedance. In your case I think you will want to set it to 4 ohm (vs the factory default of 6 ohm) I might check with Onkyo to see what they say. Good Luck TL/3683
    Clancy • 12/17/2019, 2:17:43 PM Have an older Technics AV Control Receiver with one 8 ohm front speaker output. I want to split speaker output occasionally to 2 in ceiling speakers (unknown brand and type) and 2 Bose 161 speakers. Will this splitter handle that or will the receiver be able to handle it
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Clancy: Yes this speaker selector would work but checkout the SSVC2 Speaker Selector featuring internal Impedance Matching Volume Controls plus dual source. You would be able to play both pair at the same time or you could expand your system by adding a small amplifier like our AMP120 and you could connect a iPhone or iPod and play that for your outside speakers while your inside speakers were playing surround sound. Or you could play both outdoor and the two front speakers form the iPod/iPhone. If you need further explanation, please contact me at TL/3983
    Jeffery • 12/17/2019, 2:17:43 PM can I install it on my covered patio?
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Jefferey: It depends on where the speaker selector will be located and what other components you are planning to place along with the speaker selector. Obviously being located in Houston you have a long outdoor season, the down side is you climate is very humid most of the year. So it is probably a good idea that the equipment is a cool dry place. Maybe hard to find in South Texas. Good luck TL/4092
    Eric • 12/17/2019, 2:17:43 PM What type of wire connector is needed to connect this unit to the receiver?
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Eric: This speaker selector takes either four or two conductor speaker wire stripped at the ends to insert into the screw down input/output terminals. The speaker wire will come from the speaker level outputs of your Amplifier or Stereo Receiver or even a zone 2 output of an AVR (Surround Sound Receiver). We call this a speaker (high) level connection that comes after a signal has been amplified. Versus a signal (low) level pre amplified signal before being amplified. A external amplifier is recommended when connecting multiple channels from a Receiver to a Zone 2 Pre amp output. Most zone 2 speaker level outputs recommend just connecting a single pair of speakers not a speaker selector and 4 or more pair of speakers (speaker selectors come in 2, 4, 6, 8 or 12 channel versions). In those case it is always recommended to add a good external amplifier to handle the load. TL/4107
    PAULO CAMPOS • 12/17/2019, 2:17:43 PM Dear sales friends, How I contact in sales for: I have one project to put in kiosques (on the beach in Rio de Janeiro) one rdio on-air, and I want equipate these kiosques, with: 2 x (pair) AP840, AMP200, ISS4, cables and conectors speakers, UV protected) All the best!

    Hi Paulo: I have given your lead over to our Master Distributor who covers South America. He handles all the logistics shipping to Brazil from Miami. He will be contacting you as soon as possible. Just a thought regarding your product mix, the AP-840 is not our highest rated weatherproof speaker. The AP-650 is rated at IP-6X (totally sealed cabinet) and also features a unique two way mounting bracket, both Swivels and tilts. TL/4386
