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.

54 Questions asked on ISS4 4x Pair High Power Speaker Selector with Impedance Protection and Easy Input/Output Connectors

Brian • 06/21/2020, 12:20:03 PM Q Hi, I am planning to get a Sonos Amp. The 2 channels are 8 ohms 125w each. I want the 2 pairs to play sometimes at the same time and other time 1zone off while the other zone is playing. Sonos recommend 8 ohms speakers to be in parallel. Should I still go for 8 ohms or 4 ohms using your ISS4? Thank you
Customer Service • 06/27/2020, 1:31:50 AM
A Hi Brian: The SONOS Amp/Player 125 Watt has no problem connecting two pair of 8-ohm speakers in parallel. It is rated for a 4-ohm load. We have two options for your application. One is the ISS4 four zone speaker selector where you have an on/off button per the two zones you will be connecting. The second option, a SSVC2 Two zone speaker selector with built in Internal Impedance Matching Volume controls. Not only do you have a on/off switch per zone but you have a volume control to attenuate (turn down) one or both zones independently.Neither speaker selector will be used for Impedance Matching protection. I hope that helps TimL/6-26-2020
John • 12/17/2019, 2:17:43 PM Q Will this device control speaker pairs that have different impedance levels? I have one pair of speakers that are rated 6 ohms and the other pair is 8 ohms.
Customer Service • 12/17/2019, 2:17:43 PM
A That should not be a problem. I am assuming you will be connecting more than these two pairs of speakers to the four zone box. If so, just make sure the internal protection switch is enabled (on). If you are adding impedance-matching volume controls between the box and speakers, then defeat the internal protection. TL/MA
Stephen urda • 12/17/2019, 2:17:43 PM Q I currently have a swithc that is providing Cross over between the various zones. Does this swich provide any cross over protection?

A Stephen, This speaker selector has Impedance matching. CL

Customer Service • 12/17/2019, 2:17:43 PM
A I am assuming you have a switch now that separates your zones but with no actual dedicated protection. The ISS4 Speaker Selector has a protection switch on the front that we recommend keeping enabled or in the on position (pushed in) whether you are playing 1, 2, 3 or 4 pairs at a time. The only time you would defeat the switch would be if you were using Impedance Matching Volume Controls, one for each pair of speakers. Having both the protection circuit enabled plus the Impedance Matching Volume Control would cause a conflict with the Amplifier/Receiver
Jose • 12/17/2019, 2:17:43 PM Q Can I listen more than one pair of speakers at the same time?
Customer Service • 12/17/2019, 2:17:43 PM
A Yes - you can listen up to 4 pairs of speakers at the same time.
