Product Overview +

Reliable Monitoring for Studio Talent

The RB-HD1 is a compact, robust headphone amplifier designed specifically for the rigorous demands of radio, television, and post-production studios. By providing both front and rear output options, it facilitates clean cable management in voice-over booths while providing talent with intuitive, immediate volume control.

Engineered for Flexibility

The ability to mix a mono talkback input into the main stereo feed makes the RB-HD1 a highly efficient communication tool. Whether you are adding a dedicated cue feed from a producer's mic or mixing in a secondary audio source, the independent level control ensures that your primary program feed remains unaffected.

Broadcast-Grade Build

Designed for 24/7 reliability in professional broadcast environments, the RB-HD1 features a rugged 1U rack-mount chassis. The recessed stereo/mono toggle switch is a thoughtful inclusion, specifically implemented to prevent accidental switching during active sessions. It is a dependable monitoring solution for studios requiring a "set-and-forget" headphone amplification system that stands up to the daily rigors of a professional facility.
