Create a whole-home audio system
OSD's ISS8 is a passive speaker selector that gives you the ability to create a huge whole-home audio system. You can connect and play up to eight speaker pairs (sixteen speakers total) simultaneously.
There are eight front-panel push buttons that are used to turn speaker pairs on and off. The included zone labels can be inserted into the recessed area above each button to help keep track of where your speakers are assigned.
Impedance protection lets you play it safe
The ISS8 has built-in impedance matching circuitry, which is useful if you have a few speakers wired up that present too low of an impedance for your amplifier. It helps magnify the impedance to keep your amp from overheating or shutting down. There's a button on the right side of the front panel that lets you turn the impedance matching on or off.
Note: The power the speaker selector can handle is dependent on whether or not that impedance matching circuitry is activated. When it's turned on, the speaker selector can handle up to 70 watts of power per channel. When the circuitry is turned off, it can handle up to 140 watts per channel. When in doubt, I recommend keeping it turned on to ensure safe operation.

More details on the OSD ISS8
8 Pair Speaker Selector: The OSD-Audio ISS8 Speaker Selector is an easy and effective way to distribute music to up to 8 listening zones (8 pairs of speakers) and play any pair, a combination of pairs, or all pairs simultaneously from a stereo receiver or amplifier. Each of the 8 Zones allows you to connect a pair of loudspeakers for a total of 16 speakers. Front-panel push buttons let you quickly turn each pair of speakers on or off independently, and custom labels fit within the recessed area on the buttons for easy labeling of each zone. The ISS8 is constructed of 16-gauge steel with a durable black powder coating.
Impedance Protection Circuit: A passive device that does not require power to operate, the ISS8 also includes impedance protection circuitry so you can safely drive all 8 pairs at once without damaging your stereo receiver or integrated amplifier. 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 your equipment. The ISS8 includes selectable impedanc protection circuitry that allows a single amplifier to safely power several pairs of speakers.
- Manually activating the Impedance Protection Circuit will prevent the impedance presented to your receiver or amplifier from dropping below an unsafe level of 5 Ohms, regardless of the number and impedance rating of your speakers.
- The speaker selector handles 200 watts per channel total input power without the manual Impedance Protection Circuit engaged, and 100 watts per channel with the Impedance Protection Circuit engaged.
- The ISS4 will not allow the impedance presented to your receiver or amp to drop below 5 Ohms. Make sure your stereo receiver or integrated amp can handle down to 4 ohms.
- The Impedance Protection Circuit must be activated manually by pressing "Protection Circuit Switch" button on the front-panel. The Impedance Protection Circuit is not done automatically.
Euro-Style Connectors: The ISS8 Speaker Selector is easy to install and accepts 18AWG to 14AWG speaker wire. The European-style input/output connectors are removable, which gives you better leverage when terminating your speaker wires 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.
- Make sure to use in-wall rated (CL) speaker wire when installing speaker wire inside the wall.
- 14 gauge is recommended for runs longer than 50 feet.
Mounting Options: The OSD-Audio ISS8 Speaker Selector features a low-profile design that easily fits into a cabinet or equipment rack. Never place the speaker selector where it is exposed to excessive moisture or heat. Leave at least 1" of space above the unit for heat dissipation.The ISS8 measures 17.125" (w) x 2.125" (h) x 5.0" (d), and weighs 6lbs.
