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.

What's on your mind?


Eric • 12/17/2019, 2:17:43 PM I just got this ISS4 today and please correct my set-up before I do harm to my Onkyo TX-NR809. I'm planning to expand the Zone 2 to accomodate 3 ceiling speakers for my Kitchen, Dining and Living. The speakers I'm planning to buy is Yamaha NSICS600 60w 8 ohm speakers, it's a single stereo speaker. Another thing, I have my kids also busy playing with their games on PS3 on the same entertainment center. I'm worried what will happen if they accidentally turn off the protection switch without me knowing. 1. Will I damage my Onkyo reciever if I play the Zone 2 with 3 speakers using the ISS4 if the protection switch is off? 2. Is my intention correct by multiplying Zone 2 to 3 speakers using the ISS4? 3. Would I notice reduction in volume if all 3 ceiling speakers are installed? If it does what should I do? Please advise before I start. Thank you.

Hi Eric, Based upon your application, the ISS4 speaker selector may not be the right choice. We recommend returning the ISS4 for full credit and purchasing the OSD AMP200. This AMP200 would connect directly to your Room 2 pre-amplified output (right and left RCA). Connect two of the three speakers to Speaker A and the third to speaker B. Connect the 12-volt trigger from the Onkyo (labeled Room 2, 12-volt trigger) to turn the Amp on and off automatically. Set the output of the Onkyo Room 2 to variable (page 60 of your owners manual) so the Onkyo receiver controls the volume and balance. The AMP200 is a High Current Amplifier that will have no problem running three stereo outputs (kitchen, dinning and living room area). The amplifier can handle a 2.6-ohm load, which is what you'll have with three 8-ohm stereo speakers connected in parallel. This high current amplifier is more suitable for the quality and level of the Onkyo TX-NR809 versus the compromise you'll make with a basic speaker selector with a protection switch. Regarding your choice to go with a single stereo speaker rather than a stereo pair in your three rooms, is space or accessibility limited? These speakers are typically limited to hallways, bathrooms or even master bedrooms. Check out our MK690TT speaker that features the same trim-less grill design, a dual voice coil for running a summed mono signal and dual tweeters for greater dispersion of the high frequencies. It's similar to the Yamaha speaker but features a more elaborate crossover network and a unique Kevlar cone material. Plus, our speakers feature a special dual application switch that allows them to be connected as a stereo pair where both tweeters are playing (doubling your coverage). If you would like to discuss this future, call us directly and for Tim. TL/MA - 1509
Dave • 12/17/2019, 2:17:43 PM Can you use this with the SVC300 inwall volume controls handling the impedence matching with the Single Pair Direct Switch in the off position?
Customer Service • 12/17/2019, 2:17:43 PM
Hi Dave, If you are using a speaker selector and volume control, let the volume control do the impedance matching and turn the protection off on the speaker selector. CL/MA 1594
Harry • 12/17/2019, 2:17:43 PM Is the power handling 140W RMS/CH? Will driving these with 120W RMS/CH damage it?
Customer Service • 12/17/2019, 2:17:43 PM
Hi Harry, It would be helpful to know the model number of your receiver, how you plan to wire your system and what components you plan to use. The ISS4 speaker selector handles 140 Watts RMS without impedance matching. This means you'll need a volume control on each zone doing the impedance matching. If you do not have volume controls, the ISS4's impedance protection must be activated. This would give you 70W RMS. CL/MA 1802
dan • 12/17/2019, 2:17:43 PM can (4, 8 holmes speakers) or two set's of 8 holm speakers be played at one time without damage to the speakers or amp (right and left output amp, 8 holmes each)
Customer Service • 12/17/2019, 2:17:43 PM
Hi Dan, This speaker selector is designed for 8-ohm speakers. You can connect one pair to each zone and play any variation of all or none at anytime without issue; just make sure you have adequate power. For 4 zones, we recommend our AMP200. CL/MA 1856
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 • 12/17/2019, 2:17:43 PM
Hi Pascal, Your receiver is designed to drive as many speakers as it has outputs. Therefore, we would not recommend doubling that with a speaker selector. Consider adding an amp like our AMP200. CL/MA 1948
