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.

Pascal • 12/17/2019, 2:17:43 PM I have a stereo with only outputs for 2 speakers. Can i with this speaker selector connect four spekers to a stereo? And stays the quality from the music the same? And can i with this speaker selector turn on all spekers or just one? My reciever is an phillips mcd 712.

Customer Service, You do not recommend using the speaker selector for Pascal's application but isn't that whole whole purpose of the speaker selector. Doesn't it take one set of L and R input and distributes between one, several, or all 4 zones? If I am wrong, what is the ISS4 supposed to be used for?
George • 12/17/2019, 2:17:43 PM How does this speaker selector compare to the monster cable speaker selector?
Customer Service • 12/17/2019, 2:17:43 PM
Hi George, The ISSA speaker selector has many similar features; however, we encourage you to review the specs on both models before making your decision. CL/MA 2015
Carlos • 12/17/2019, 2:17:43 PM I want to connect Monitor Audio Silver RX-8 Speakers (4 Ohms) to my Pioneer Elite VSX-94THX Receiver (8 Ohms). I also want to run a set of 4 ea. Bose 161 rated 4-8 ohms. I would like to know if this speaker selector will be the right device to handle the impedance mismatch between the MA speakers and the receiver and if that wouldn't affect the Bose speakers.
Customer Service • 12/17/2019, 2:17:43 PM
Carlos, We typically wouldn't recommend running any kind of speaker selector off a home theater receiver. The reason being that these receivers usually don't have enough power per channel to run multiple pairs of speakers, and they can usually only handle an 8ohm load. While the speaker selector will correct the impedance, it could still cause issues. Also, when using the impedance protection on a speaker selector, about 50% of the power is absorbed, making it even less power going through to the speakers. I would recommend getting yourself a high current external amp to run off the receiver and power your stereo speakers around the house. Take a look at our AMP200 or AMP300 as examples of what to use in line with a speaker selector. -BM
Brian • 12/17/2019, 2:17:43 PM I am looking to use the ISS4 to distribute power to 2 pairs of 8 ohm speakers off a powered Zone 2 on an Onkyo TX-SR805. Would this be appropriate? Is there enough power? What would i set the impedance matching on the volume control to?
Customer Service • 12/17/2019, 2:17:43 PM
Hi Brian Thanks for contacting us. Based on the specs of your reciever, it seems that you should have no problem powering 2 pairs of speakers off of the zone two output channel on your receiver. We recommend using speakers with 5.25" or 6.5" woofers. For the ISS4, make sure that the Impedance protection is turned OFF since you are using impedance matching volume controls. Set the volume controls to the 1/2X setting. The receiver is rated at 130W power output per channel which should be more than adequate for your set up. If you have any other questions please call us at 562.697.2600 DB 2130
John • 12/17/2019, 2:17:43 PM I am totally confused by your answer to Pascal from the Netherlands which is "Your receiver is designed to drive as many speakers as it has outputs. Therefore, we would not recommend doubling that with a speaker selector". I thought the whole purpose of the speaker selector was to allow you to hook up more pairs of speakers to a receiver that it can handle? I have a receiver that can handle 2 pairs of speakers but we have 4 pair in our house. Please clarify. Thanks.

Hi John: Sorry for the confusion. In the US most people who want to add a speaker selector are trying to do so with a second room output from a Audio/Video 7.1 Receiver which is limited to how many speakers can be driven off off the channels 6 and 7 of a 7 channel amplifier that is sharing a common power supply to power all channels. So that is when we typically recommend going with an additional amplifier. In Pascal's case we should have asked what type of Receiver he was using either a two channel receiver or an AVR. In the case of the two channel he could have used a speaker selector like the ISS4 to drive two, three or four speakers at once. They would just have to make sure the protection switch was enabled (on). Of course that would only be true if you were planning to use just the speaker selector and no Volume Controls. If on the other hand you were to use independent Impedance matching Volume Controls (one control for each zone connected) then the Volume Controls would handle the protection and the Speaker Selector's Protection switch would be disabled (off). This is the better of the two choices allowing the Impedance Matching Volume Controls handle the Protection. The Speaker Selector you will notice in the specs is rated at 70 watts with the protection enabled versus 140 watts when disabled. So better to let the impedance Matching Volume Controls handle the protection. So, I would pose the question to you about what type of Receiver you are planning to drive the multiple pairs of speakers? The Brand, Model and type would be very helpful. TL-2143
