    The ISS6 High Power Speaker Selector is an easy and effective way to distribute music to up to six listening zones (six 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 ISS6 also includes impedance-matching circuitry so you can safely drive all six pairs at once without damaging your receiver or amp. Designed with quality in mind, the ISS6 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 ISS6 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.

    Eric • 12/17/2019, 2:17:43 PM Will this unit work without connecting a 2nd amp, if I have an Onkyo TX-NR709 Av receiver, it has a zone 2 option. Looking to have 6 zones of music thou the house. with some builder grade speaker or a step up. Thanks Eric
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Eric, Typically with multi-rooms, the receiver alone is not enough power to run your surround sound and 6 additional zones with the "Zone 2". Most customers add an amp to power the whole house. After reviewing the extensive manual for your Onkyo receiver, you'll notice on page 63 it talks about Zone 2. You have two options: powered utilizing the 110 Watts per channel that was intended for Channel 6 and 7 of a 7.1 system. This will work if you were planning to run a single pair of speakers for the second zone. But in the case where you want to connect up to six zones, we would recommend utilizing the signal level preouts for Zone 2 to connect to a High Current external amplifier like our OSD AMP200. Then you can use a speaker selector like our ISS6 or DSM6 to control the 6 individual zones. Each of these speaker selectors features switchable protection. Ideally, you can add an impedance-matching volume control for each zone as well. This features more control in each zone while providing a better way to protect your system than the internal protection of the Speaker Selector (which you would disable). Note we also offer a large selection of Custom Install speakers for both inside and outside in all different shapes, sizes and price ranges. Please let us know if this information helped. CL/TL
    Randal Limberg • 12/17/2019, 2:17:43 PM I am currently using this switch with my Sonos Connect Amp for three sets of hard wired speakers. I would like to add the Outdoor Rock Speakers with the WR150 Connected to one of the switch positions. It looks as if I can connect usibg an RCA type cable making sure that I stay within wireless transmitter range restrictions. Do you see any problems?
    Customer Service • 12/17/2019, 2:17:43 PM
    HI Randal: The WR-150 Wireless Speakers will not work with the OSD-ISS6. The Transmitter only has an input (no output connection) so once it is connected to a source it transmits to the main speaker which features an internal Wireless receiver and also Power Amplifier. A second satellite speaker is connected by a speaker wire. We have any number of Rock speakers but they need to be hard wired back to the speaker selector. Sorry about that TL-2113 • 12/17/2019, 2:17:43 PM With this unit - can you have multiple zones selected at one time? For an example, zones (1) and (2) at one time or does the unit allow (1) to be pressed at one time.
    Customer Service • 12/17/2019, 2:17:43 PM
    Hello, Yes. The ISS6 will allow you to run as many zones as you want at any given time. You can run all at once, or you can choose which ones to have running while the others are deactivated. Just make sure that you are running a proper amp for that many speakers. You don't want to run a receiver. Check out our AMP300 for an example of what type of amp is needed to run this type of load. Thanks! BM 2646
    Jeff • 12/17/2019, 2:17:43 PM Does this speaker selector have a mono bridge? I want to connect a bunch of single speakers and not speaker pairs throughout my house? Will this device solve that situation? If not, are there any OSD devices which would?
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Jeff, What type of amp would you be bridging to it? How many watts does that amp output in bridged mode?
    K • 12/17/2019, 2:17:43 PM Hello, I'm thinking of using the selector for a different purpose, and would appreciate any advice. I live in a rowhouse and have a small 5.1 system (Samsung ht-f6530). I can't always have the subwoofer on (even at the lowest setting). Could I run all the 6 speakers through the selector, and turn them off as needed? I would then have control on each of the speaker and keep my neighbors happy. Thank you, K
    Customer Service • 12/17/2019, 2:17:43 PM
    Unfortunately that will not work. The home theater receiver has outputs for each speaker. The Speaker selector only has one input for source. On top of that, the receiver can only handle one speaker per output. Running all speakers off one output like that would damage your components. Call us for recommendations.
