Extron ASA 204 Four-Input Analog Stereo Audio Input
The Extron ASA 204 is a compact, four-input, one-output analog stereo audio switcher designed for reliable source selection of balanced or unbalanced line-level stereo audio signals in professional AV systems. It accepts four stereo audio sources on captive screw connectors and provides clean, low-noise switching with excellent signal integrity to a single output destination such as an amplifier, DSP, recorder, or presentation system. The switcher is ideal for applications requiring multi-source audio routing in classrooms, conference rooms, boardrooms, training facilities, control systems, or small-scale mixing setups where four stereo audio sources need to be selectively routed without complex processing.
Featuring a rugged metal enclosure, front-panel push-button switching with LED indicators for active input selection, and RS-232 serial control for integration with AV controllers or automation systems, the ASA 204 delivers dependable performance with minimal setup. Its small form factor allows easy mounting under tables, in racks, or behind equipment, while the captive screw terminals ensure secure, vibration-resistant connections in permanent installations.
