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.

Ayo • 12/17/2019, 2:17:43 PM Good day I have Onkyo Receiver with AIRPLAY and AIREXPRESS NETWORK by APPLE, planning of extends speakers wirelessly to 8 zones. Can I use this to accomplish my tasks. Another Questions, I planned to use in-Ceiling speakers, do you have wireless speakers to use with Onkyo TXNR656 model. Thanks 2nd question planned to use this in overseas (The Onkyo - 220volts) Urgently needed
Customer Service • 12/17/2019, 2:17:43 PM
HI Ayo: The ONKYO TX NR 565 is not 220 V at least not the one you would buy in North America. I am assuming you would be able to find a CE version in Europe that is 220V. The ISS8 would work but the TSM8 would work better especially since you are not planning to use Impedance Matching Volume Controls on each pair of speakers. The TSM has a much better internal protection than the ISS8. If you are planning to run the 8 pair of speakers off Zone 2 output of the ONKYO Receiver the you will have to run an external Amplifier like our AMP200 which will work 220V. This will power the TSM and 8 pair of speakers. I am assuming you will be using the ONKYO Receiver for 7.2 or 5.2.2 Dolby Atmos. WE have many options for your 7 channels and powered Sub woofers that are Multi Voltage as well. Checkout our ACE 870 and ACE 670 angled speakers, the ultimate LCR, Surround and Effects speakers we sell. Good luck TL/4139
Luke W Milka • 12/17/2019, 2:17:43 PM I want to us this on a police scanner so I can pick a zone at a time inside and out of my house. I will only be using one side of the switch ( left or right ). Do you see any problems using it this case?
Customer Service • 12/17/2019, 2:17:43 PM
HI Luke: I don't see any problems it is just a patch bay that organizes the wires in parallel. We had people wire it in Mono, just one of the channels. TL/4619
Ornon • 12/17/2019, 2:17:43 PM I am using a Technics SU-V9 vintage intergrated amp pushing 120 watts per channel. I would like to know if this would be compatiable to old analogue stero systems? The Su-V9 amp was the flagship of technics back in the day but had only A and B channels for speakers. The problem is they cannot have both A and B on at the same time. I would like to be able to set up my stereo with zones so I can listen to at isolated location inside and out my Cabin?

HI Oman: The ISS8 is a good choice if you are planning on using Impedance Matching volume controls, one for each zone you are planning. The DSM8 is a better choice if you are planning two sources (another in addition to your Technics). These also need to have Impedance matching Volume Controls (we have interior and exterior choices as well). Both the ISS and DSM series Volume Controls feature internal protection when enabled reduces the power handling capability cutting it in half (140 down to 70) which is why we recommend the Impedance matching Volume Controls to handle the protection. In some cases where it is not piratical to add Volume Controls we recommend either the TSM8 (8 zone) or TSM 12 (12 zone) speaker selectors which feature large internal Transformers to provide the protection with out the deep loss in power handling. We also provide the SSVC series which feature the Volume Controls built in (one per zone). The 1, 2 and 4 zone versions feature selectable A or B per zone as well. The SSVC6D features A or B for all six outputs with a single master A/B switch. The Technics was obviously an 8 ohm only amp allowing you to play just a single pair either A or B but not together. If you connected two pair in parallel the impedance would drop to 4 ohms. The unit is an integrated amp that has the Pre amplifier built in. The specs I saw said it can go down to 4 ohm so it should have no problem in the whole House. I hope that helps. We can help with the layout, would just need blueprint and images and alist of equipment you have. TL/4749
Rod Campagna • 12/17/2019, 2:17:43 PM I have a Pioneer Audio Video Multi Channel VSX-517 Receiver that I want to use the ISS8 to connect to 8 zones in my home. Will this product work for me? Each zone has a volume control.... not sure if this matters, just wanted to include this. I am novice when t come to audio equipment. I just want to hook all speaker in my home to this receiver and select different areas in my home to listen to music. Thanks for your help. Rod C
Customer Service • 12/17/2019, 2:17:43 PM
Hi Rod: Yes, you can connect the ISS8 to your Pioneer VSX-517 as long as that is all you are connecting your Pioneer Receiver too. Note, you will want to have an Impedance Matching Volume Control for each zone and all the must be set to 8X. Then make sure you do not use the Protection switch on the front panel. The Impedance Matching Volume Controls will do the heavy lifting (protection). When you use the protection switch it directs the audio signal through the internal resistors cutting your power handling in half from 140 watts to 70 watts. You could step up to a DSM8 for future expansion since it features Dual source input. You could add our AMP200 and a number of sources including Alexa, Chromecast Audio or SONOS Connect. Then with a flick of an A/B button per zone, you could play different sources through different zones at the same time. I hope that helps, contact me if I can be of further assistance; TL/5102
thomas gremillion • 12/17/2019, 2:17:43 PM i have a Sony ES 4300 that powers my home theater, i have 4 outdoor speakers around my pool that i would like to power with that receiver. I would like to be able to play the outdoor speakers without the indoor speakers playing ,and vice versa. Will this work, and if not, what would i need to do that?
Customer Service • 12/17/2019, 2:17:43 PM
Hi Thomas: Interesting question regarding your system, but I have a few questions myself to better answer you. First, is the SONY model the ES STR-4300? How many speakers do you have for your home theater, 5.1 or 7.1? When, you say four speakers outdoors, are these pairs (4 pairs) or 4 each? I believe either way you will need a separate external amplifier for your outdoor speakers. Two pairs would be connected Amplifiers Speaker A and B. Four pairs might call for the addition of a speaker selector. The external Amplifier would be connected to the Zone 2 Right and Left Audio output. You can play an independent source outside while either listening/watching a movie or listening to the stereo mode for your front and surround sound speakers. My contact info is TL/5339
