4-Channel High Power Stereo Speaker Selector Switch with Impedance Matching Protection and Easy Input/Output Connectors - ISS4

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.

The manual power protection switch engages 10 ohm /15 watt resistors wired in parallel, three per channel in the ISS8 or two per channel in the ISS6/ISS4 providing higher power handling capability than the competition (able to handle up to 50% more power!) in order to protect your amplifier. All ISS’s are capable of handling 140 watts per channel total input power without the manual protection engaged and 70 watts per channel with the protection engaged.

The better screw in terminals accept up to 14 gauge cable. The ISS’s feature 16 gauge steel construction with our durable black wrinkle powder coating and gray silk-screening. Each unit is provided with an in-depth instruction sheet and die cut labels that fit the recessed area on the buttons for labeling each zone. The 8.5" chassis width of the ISS4 combines with other 8.5" wide OSD Audio components (which will be available in the future) to make a standard 17" wide unit.

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, the ISS4 speaker selector includes a dual source input so you can choose between two audio sources. 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.

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 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 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.
