Lifetime Tech Support

The ISS8 High Power Speaker Selector is an easy and effective way to distribute music to up to eight 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 ISS8 also includes impedance-matching circuitry so you can safely drive all eight pairs at once without damaging your receiver or amp. Designed with quality in mind, the ISS8 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 prolife with beautiful black brushed aluminum finish
  • Works with any amplifier 
  • Includes a two-year warranty
Upgraded Input/Output Connectors
The ISS8 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 ISS8 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?

Newhouse • 12/17/2019, 2:17:43 PM Can I turn on all 8 zones at the same time with this? Or I can only play one zone at a time. Thanks

Hi, I am planning on purchasing your AMP300. I have one last question. My new house have 7 Zones. Zone 2,3 and 4, each only have one speaker. All zones have in wall volume control. I can not tell whether I need the ATM-7 or DSM8 with the AMP300. Can you please give me a recommendation? Also, how I connect my zone 2,3 and 4? Would I bridge left and right speaker those zone? Sorry, I am a non-tech. Thank you.
Jay Johnson • 12/17/2019, 2:17:43 PM Do you make a rack kit for it? Can you give me the deminsions?
Customer Service • 12/17/2019, 2:17:43 PM
Hi Jay, We do not carry a rack for this speaker selector. The dimensions are 17"W x 4 1/2"D x 1 3/4"H. CL/MA 2020
Newhouse • 12/17/2019, 2:17:43 PM I have the AMP300 and my house has 7 zones but the zone 2,3 and 4 is only one speaker. Can you please tell which speaker selector would be best for me. I am thinking of the ATM-7 or the DSM8 (ISS8) I could not tell the difference between. Other than ATM-7 has a remote. Can you please giver an advise? Also how I would connect my speaker in zone 2,3,4. Should I bridge left and right to that single speaker ? All zones have volume control. Thank you
Customer Service • 12/17/2019, 2:17:43 PM
Hi Newhouse, All of our speaker selectors are designed to run in stereo, with a left and right channel per zone. Consider replacing those speakers with a single stereo speaker like our MK690TT which has a left and right connection to each of the two tweeters. This gives you stereo sound with just one speaker. The ATM-7 requires you to use impedance matching volume controls. The DSM8 is solid but the ATM-7 has a volume control that allows you to control which zones are on. Do not bridge the zones together. Either connect left or right. Replacing those with a single stereo speaker would be ideal. CL/MA 2021
rob gray • 12/17/2019, 2:17:43 PM is there anyway to operate this unit from another room remotely either by RF or IR ?
Customer Service • 12/17/2019, 2:17:43 PM
Rob, Good question! Unfortunately the only speaker selector that we sell that is IR enabled, is the ATM-7. The ISS, DSM, SSVC, and TSM series are all analog with no IR/RF capability. Note that if you do go with the ATM-7, you need to use impedance matching volume controls on each zone, as it is also the only selector which we carry that doesn't have impedance protection. -BM 2080
Mike • 12/17/2019, 2:17:43 PM Can I hook sinlge speakers up in each room. And if so how would it get wired in stereo back to the switch out puts?
Customer Service • 12/17/2019, 2:17:43 PM
Mike, You can connect a dual-tweeter speaker off each zone, giving you stereo sound out of one speaker. The dual-tweeter speakers, such as the ICE640TT, have two terminals for stereo input. Thanks! -BM 2213
