Sonifex RB-OA3

The Sonifex RB-OA3 is a high-quality triple output stereo distribution amplifier designed specifically for broadcast and professional audio environments. It allows a single stereo input to be reliably distributed to three separate stereo outputs, each electronically balanced and independently buffered to maintain signal integrity and isolation.

Built for 24/7 operation in demanding studio conditions, the RB-OA3 is ideal for distributing audio to multiple destinations such as recorders, processors, transmitters, or monitoring systems. Its ultra-low distortion circuitry and high headroom ensure transparent signal handling, whether you’re working with analog broadcast chains or integrating with digital systems via D-A conversion.

Connectivity is straightforward thanks to high-quality XLR inputs and outputs on the rear panel. An internal level control trim allows gain matching to suit your setup without introducing noise or coloration. As with all Sonifex hardware, the RB-OA3 is housed in a durable 1U rackmount chassis, designed to withstand the rigours of studio, OB, and commercial AV installations.

Whether you’re distributing programme audio, splitting feeds for redundancy, or routing audio across multiple zones, the Sonifex RB-OA3 offers unmatched reliability, low noise, and solid performance in a clean and compact form factor.
