    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.

    Jack • 12/17/2019, 2:17:43 PM Will this work with my Sony STR-DN850? I want to take the front left and right channels from the Sony and input them into the OSD-ISS4 which will then be connected to 3 pairs of OSD AP-650 speakers.

    Hi Jack, It is not recommended to run a speaker selector with a standard receiver as receivers can typically only handle 8ohms. You would want a high current amp such as our AMP200 to run this speaker selector.
    Jim • 12/17/2019, 2:17:43 PM Can this be used on a boat to control 4 pairs of speakers using a 2 channel marine amplifier and a marine 12v stereo.? Thank you
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Jim, It's a passive device so as long as it's protected from moisture you should be fine.
    carl beasley • 12/17/2019, 2:17:43 PM I have a yamaha RX-A3030 4zone receiver/amp. Zone 3 is powering A pair of rs850 and pair of Rsub300, one on each side of my pool. I want to add a pair of AW-6500 overhead. Can this switch and amp handle that setup?
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Carl, This speaker selector can run the speakers but I'm not positive whether or not your receiver can handle that type of load. Usually you'd want to run that many speakers off a high-current amp such as our AMP200 or AMP300.
    Cesar • 12/17/2019, 2:17:43 PM Does this work for a 70v speakers?
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Cesar, This only works with 8ohm systems.
    Brad • 12/17/2019, 2:17:43 PM I have an ONKYO TX-NR609 amp/receiver and am planning to hook up zone 2 to the ISS4 speaker selector to run two sets of outdoor speakers (RS670 rock speakers). My amp says Speaker Impedance 6 to 16 ohms. So does that mean I can run both sets of speakers without any impedance protection?
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Brad, It wouldn't be safe to run anything more than 1 speaker per output on your receiver. That type of receiver isn't intended to power multiple speakers off each output. Running 2 pairs would create a 4ohm load which would be unstable for your receiver. It may be a good idea to get yourself an amp to pair with your receiver that has enough power to run multiple speakers. Check out our AMP200!
