The Broadcast-Grade Dual Pre-Amp

The RB-MA2 is the ideal solution for studio environments requiring high-quality, reliable microphone amplification in a compact form factor. By providing two fully independent channels in a single 1U unit, it allows for efficient space utilization in equipment racks while maintaining the superior sonic performance required for professional broadcast and live sound reinforcement.

Engineered for Challenging Installs

The ability to switch phantom power and low-cut filters per-channel gives technical operators the versatility to handle diverse microphone types—from dynamic to sensitive condensers—within the same rack space.

Essential Utility for Every Studio

As a core component of the Redbox line, the RB-MA2 offers the low noise (-130dB E.I.N.) and high headroom (+28dBu max output) needed to keep audio signals clean from capture to destination. It is a dependable, high-fidelity workhorse that ensures audio integrity across complex production environments in Karachi and beyond.
