Extron ASA 111 Analog Stereo Audio Input
The Extron ASA 111 is a compact, one-input, one-output analog stereo audio switcher designed for simple, reliable switching of balanced or unbalanced stereo audio signals in professional AV systems. It accepts stereo audio on captive screw connectors and provides clean, low-noise switching with excellent signal integrity for line-level sources such as mixers, media players, or presentation switchers. The switcher is ideal for applications requiring basic audio routing in classrooms, conference rooms, boardrooms, training facilities, or control systems where a single stereo audio source needs to be selectively routed to an amplifier, recorder, or other destination.
Featuring a rugged metal enclosure, front-panel toggle switch for manual control, and optional RS-232 serial control for integration with AV controllers or automation systems, the ASA 111 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.
