 SW 8A RCA Eight Input Audio - RCA 60-482-30 Retired

This product has been retired.

The Extron SW 8A is a high performance stereo audio switcher that accepts balanced/stereo audio on captive screw connectors. It includes adjustable gain and attenuation, allowing users to set the individual input audio levels, providing no significant difference in volume when switching between sources. All SW AV switchers can be controlled via the front panel buttons, RS-232, or via two different, optional remote control devices: the Extron KP 6 keypad and IR 102 universal remote.
