Features & Specifications

• Distributes audio from your amplifier to up to eight pairs of speakers
• Includes individual on/off selectors for each zone
• Play one pair, a combination of pairs, or all pairs simultaneously
• Impedance protection allows a single amplifier to safely power multiple speakers
• Control audio in eight zones
• Removable input/output connectors allow easy cable termination
• Includes on/off switches for each zone
• Low profile with black brushed aluminum finish
• Includes a two warranty

Designed to distribute audio to up to eight pairs of speakers, the ISS8 High Power Speaker Selector puts you in control of your whole house audio by giving you the option to play any pair, a combination of pairs, or all pairs of speakers simultaneously and control the volume. Easy to connect with a low-profile design that fits into a cabinet or equipment rack, the ISS8 speaker selector includes a dual source input so you can choose between two audio sources, and we even include die cut labels that fit within the recessed area on the buttons so you can label your audio zones (e.g., Bedroom, Kitchen, etc.,).

A passive device that connects to a high-current amplifier, front-panel push buttons let you turn each pair of speakers on or off independently, and the ISS8 also includes impedance-matching circuitry so you can safely drive all eight pair at once without damaging your equipment. Keep in mind that running eight pairs of speakers will require a high-current amp such as our AMP300 or a multi-zone amp such as our MX1260. Using an A/V receiver alone is not recommended.

Designed with quality in mind, the ISS8 is constructed of heavy-duty steel with a durable black powder coating, and we’re so confident you will love the ISS8, we include a five-year warranty.

Easy to Connect

You don’t need to be a tech-head to install the ISS8 speaker selector. We designed in European-style input/output connectors that are removeable, which gives you better leverage when terminating cable than traditional spring-loaded terminals. This speaker selector takes either four or two conductor speaker wire (up to 14-guage) 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 an 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 multiple pairs of speakers. This speaker selector handles 140 watts per channel total input power without the manual protection engaged and 70 watts per channel with the protection engaged.


Other Product Info

The ISS4, ISS6 and ISS8 are low-profile speaker distribution systems with individual on/off selectors for each listening zone which distribute one stereo speaker-level signal to eight, six or four stereo listening zones. The ISS Series also provides manual power protection that is activated from the rear panel.

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
1 Answer
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

November 9, 2016
I am thinking of buying this unit to power 16 speaker. Here is my setup :-- each room have 2 speakers and 2 wire cable comes from both speakers to my keypad location and at keypad location I had 2 -2cable speaker wire from 2 speakers and one 4 conductor cable which run from keypad location to back of my cabinet ( where I'll install this unit along with yahama rx667 or rx740 receiver with zone 2 feature. I Am also planning to use sv100 or sv300 keypad along with this unit. So I wanna know if my yahama receiver is ok to power 8 zones. Also what is the diff between Iss8 and dss8 model ? Which one suits my setup ? Please advice.
1 Answer
Hi Ruby: Most if not all Receiver manufacturers do not recommend connecting multiple speakers to the ZONE 2 output on the Yamaha V-667 (also labeled presence). This is recommended for a single pair of speakers only. Adding multiple speakers puts too much strain with the single power supply that powers all 7 channels.The unit does have a Zone 2 Pre amp output that we recommend using an external amplifier like our OSD AMP200 then add your speaker selector. volume controls then the speakers. It is recommended you use an impedance matching volume control like the SVC300 for each zone and let them provide the protection for the amplifier. In this scenario you would make sure to disable the protection switch on the ISS8 or DSM8; both are rated 140 watts when protection is disabled versus 70 watts per channel with it enabled. The Volume controls do a better job of impedance matching. The AMP200 is a high current amplifier so would recommend you set all volume controls to 4X and make sure you turn off the zones you are not using versus depending on turning the volume control to inaudible levels (all the way counterclockwise). The DSM8 has identical specs as the ISS8 but a nicer Black Brushed Aluminum face Plate and features dual source with independent A or B source switching per zone. This allows you to listen to two different sources at the same time on different zones. You could play Source A for zones 1, 3, 5, and 8 and Source B on Zones 2, 4, 6 and 7 as an example. Both boxes feature removable input/output terminal connectors. Note the ZONE 2 from the Receiver will allow you to use an App to control the source. I hope that helps TL/4120

Mario Abdalah
from Santiago, Chile asked:
July 12, 2016
Can I use 2 units to connect 8 pairs of speakers to 8 amps (taking the necessary safeguards obviously), as shown in the accompanying photo. I own about 6 different amps and 8 different pairs of speakers.
1 Answer
Hi Mario: These boxes could be connected as you have illustrated since they really are just passive switchers that could go both ways. My concern is with the speaker selector box with the speakers connected. Whether it is the six in your picture or 8 as you noted in your description. If you were to run more than 2 or 3 pair of speakers at a time the internal protection would need to enabled (button pushed in). Note when the internal protection is enabled the power rating is cut in half. Also note; I would leave the Protection disabled on the Speaker selector connected to the 6 amps. You would only need a ISS6 and ISS8 for the speakers. But checkout our TSM8 which features selectable protection so you could set the protection to the actual number of speakers you are wanting to play. It also features Dual Source which might even give you more flexibility. Either way you will want to use the internal protection on the speaker selector connected to the speakers. Interesting setup, would like to know what else makes up your system. TL/3980

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?
1 Answer
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

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
1 Answer
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

Hi Jim: Are you planning to use the ISS8 to power all eight zones? Are you using Impedance matching Volume Controls for each zone or depending on the Internal Protection. I am assuming you are using the Denon as a Stereo Amplifier. Not sure what output you will get from the surrounds. The entry level Home Theater Receivers will definitely want to see a consistent 8 ohm load. Good Luck TL/3725

I have a Yamaha RS-500 (75 watts). With this switch can I run all 8 sets of speakers at the same time? And, what does the "manual protection to the amp" described in the listing mean?
1 Answer
Hi Mark, I wouldn't recommend it. Typically you're gonna need a higher powered amp to run this many speakers, such as our AMP300. Running that many speakers off a standard receiver is very risky and can lead to damaged equipment.

Open to suggestions. Thanks, Jim
1 Answer
Hi Jim, The Bose speakers should be fine. Does the subwoofer have a built in crossover? Is it powered and you're just trying to send audio signal via speaker level input or are you trying to power the sub with a stereo amp? If it's a passive sub then it won't work unless it has a built in crossover to filter out the highs. If it's a powered sub and you're just trying to send audio to speaker level input, that may work but we haven't tested it. You probably won't be able to run these off your current receiver as it's only meant to run at 8ohms. I would recommend running an external amp from that receiver, such as our AMP200 or AMP300, and run the speaker selector from either of these amps. Let us know if you have any further questions.

Can you hook up in-wall volume controls with this speaker selector in 1 or more zones? and I also want to know if my Yamaha HTR-5440 AV receiver has enough power to have with particular speaker selector. or will I have to get a amp to assist with the power? thanks so much.
1 Answer
Hi Nathan, Yes - this speaker selector actually works best with impedance matching volume controls on all zones that will be active. The reason being that the impedance matching volume controls (ex. SVC300) do a more efficient job at controlling impedance than the selector does. Thus, if you run 8 SVC300s set to "8x", and disable the impedance protection on the selector, you will get the optimal output of power from your amp. Regarding your receiver, I wouldn't recommend it. Typically this kind of receiver can only handle an 8ohm load which you won't necessarily get even with impedance matching. On top of that, you wouldn't have enough watts to safely power all speakers. You should run our AMP300 to the ISS8 and an SVC300 for each zone. You can still run your receiver to the amp as a music source via RCA cable. Let us know if you have any further questions. Thanks. -BM 2616

I bought 6 ICE810 and the 8 Zone Multi Room Audio Kit. I'm finally getting around to wiring this up and realized that these speakers do not have stereo input, however, the kit that I was sold requires stereo output. Is there a way to make my system work? I can only put 1 speaker in each room. Can I bridge the L/R outputs on the zones with this speaker selector.
1 Answer
Hi Brian, The ICE810's are mono requiring 2 to be used in pairs for stereo applications. You can use a 4 zone speaker selector to control the 3 pairs or you can use each of the 6 ICE810's in mono with a 6 zone selector. If you use as 6 zone, you will have 6 additional un-used outputs for future expansion. CS 2561

is there anyway to operate this unit from another room remotely either by RF or IR ?
1 Answer
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

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
1 Answer
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

I bought this to allow me to add speakers to my garage/mancave and outdoor deck/yard areas rather than just using the "speaker A and B" switch on my receiver and winding up with cruddy sound. This gives great and SIMPLE flexibilty as to which speakers I have on in different areas. Although I don't need the 8 pair switch now (currently only have 4 pairs)I will be able to add more when I feel like annoying the wife even further. So what's not to love about that?

ISS8 Delivers As Promised
I have an old Kenwood amp that puts out 90w per channel and has two pair of speaker outputs, A and B. We built a new home with nine speaker pairs and impedance matching volume controls. I'm using the A output to drive one speaker pair for the TV and the B output to drive the ISS8. It works perfectly. At mid-point on the volume controls, the sound level on the A and B outputs is almost identical, so there's no appreciable loss in volume from the ISS8. As a novice, I spent quite a bit of time researching speaker selectors. The ISS8 appeared to have what I was looking for at a price point I could afford should I make the wrong choice. I didn't. This was a great buy.
