Extron AXI 22 AT D Plus Dual-Channel Analog Audio Interface with Transformer Isolation AXI 22 AT D Plus & WPD 102 XLRM Kit – White

The Extron AXI 22 AT D Plus is a compact, dual-channel analog stereo audio interface that converts unbalanced stereo audio from consumer sources to balanced stereo audio for professional AV systems. It accepts two independent stereo audio inputs on dual RCA connectors per channel and outputs balanced stereo audio on captive screw terminals, providing clean signal conversion with transformer isolation to eliminate hum and ground loops. This interface is ideal for integrating multiple consumer devices with RCA outputssuch as media players, laptops, DVD/Blu-ray players, or set-top boxesinto balanced audio chains with amplifiers, DSPs, mixers, matrix switchers, or presentation systems in classrooms, conference rooms, boardrooms, training facilities, and control environments.

Featuring transformer-based galvanic isolation on each channel, independent adjustable gain control (12 dB per channel) for precise level matching, and a rugged metal enclosure, the AXI 22 AT D Plus ensures reliable, low-noise performance in mixed consumer-professional AV setups. Its small form factor allows easy mounting under tables, in racks, or behind equipment, while captive screw terminals provide secure, vibration-resistant connections for permanent installations.
