OSD Audio 4 Zone Speaker Selector Switch Impedance Protection ISS4

OSD Audio’s ISS4 High Power Speaker Selector is an affordable way to distribute audio to multiple listening zones within a home or office environment. Capable of controlling up to four pairs of speakers, the ISS4 gives you the freedom of choice to play any pair, a combination of pairs, or all pairs simultaneously, while dual source inputs allow you to toggle between two audio sources. The low-profile slips into a cabinet or equipment rack, and front-panel push buttons let you quickly turn each pair of speakers on or off independently.

Easy to install, the ISS4 accepts up to 14-gauge cable and includes removeable European-style input/output connectors that give you better leverage when terminating cable than traditional spring-loaded terminals. Constructed of 16-gauge steel with a durable black powder coating and gray silk-screening, the ISS4 also includes impedance-matching circuitry so you can safely drive all four pairs of speakers at once without damaging your receiver or amp.
