Radial Pro48 Active 48V Direct Box - High-Output Signal Handling
The Radial Pro48 is a compact, phantom-powered active direct box designed for high-output instruments like active basses and acoustic guitars, delivering natural, uncolored tone without distortion. Powered by 48V phantom power—no batteries required—it boosts internal rails to 9V for exceptional headroom, handling signals up to +21 dBu with a smooth, linear response from 20 Hz to 40 kHz. Ideal for stage and studio, the Pro48 eliminates ground loops and hum via a ground lift, while a -15 dB pad tames hot signals. Its rugged steel chassis withstands touring, making it a reliable choice for musicians and engineers.
Exceptional Headroom and Clarity
The Pro48's innovative switching power supply increases headroom, producing less distortion and a natural signal transfer that rivals high-end DIs. It excels with battery-powered active basses and acoustics that overload standard boxes, providing a round, smooth sound for recording or live performance without artifact.
