Product Overview +

Elite Performance for Studio Distribution

The RB-HD2 is designed as a high-performance distribution amplifier, specifically built to take a master program feed and reliably drive multiple headphone monitoring positions. By utilizing individually buffered outputs, it ensures that one listener's volume adjustments never impact the signal fidelity or levels of another, providing a clean, professional monitoring experience for studio guests or engineering staff.

Engineered for Precision

The inclusion of master pre-set input controls is a major advantage for technical directors, allowing the unit to be calibrated to the specific output levels of your existing mixing desk. Whether you are working with consumer-grade or professional broadcast consoles, the RB-HD2 ensures your output is always optimized for maximum dynamic range and minimal noise floor.

Built for Reliability

Consistent with Redbox standards, the RB-HD2 features a robust 1U aluminium enclosure designed for the heavy-duty demands of broadcast facilities in Pakistan, Africa, and the UAE. Its ability to switch to a mono feed at the rear panel makes it a versatile solution for checking signal phasing or providing clear talkback cues to all connected users, solidifying its place as a dependable workhorse in any professional studio environment.
