Essential Information About the Radial Pro48 Active DI Box
- High-performance active DI designed for instruments with high output levels (pre-amplified electro-acoustic guitars, active or passive basses).
- Increased headroom thanks to an internal switching power supply: less distortion and a linear response from 20 Hz up to over 40 kHz.
- Comprehensive connectivity with 6.35mm Jack input, 6.35mm parallel output, and balanced XLR output for the console.
- Essential stage tools: -15 dB attenuation pad and ground lift switch, phantom powered.
The Pro48 in Radial's DNA
Designed to meet the demands of musicians and technicians, the Radial Pro48 continues the legacy of DI boxes known for their reliability and transparency. Its active architecture and switching power supply provide comfortable dynamic range, ideal when other active DIs reach their limits with powerful signals.
Intended Uses and Audience
The Pro48 is perfectly suited for electro-acoustic guitarists, bassists, and multi-instrumentalists seeking a clean, stable, and quiet DI both in the studio and on stage. The parallel output allows powering an amplifier for playing and inspiration, while the balanced XLR output sends a mix-ready signal to the front of house or recorder.

Questions frequently asked
Is the Radial Pro48 suitable for an active bass or an electro-acoustic guitar?
The active design accepts up to +9 dBu at the input and features a -15 dB pad for high-level sources. This setup is suitable for basses, electro-acoustic guitars, and other instruments requiring an active DI.
Can an amplifier be connected at the same time as the mixer?
The parallel Jack output allows connection to an amplifier, while the balanced XLR output sends the signal to a mixer or recorder. The XLR output is suitable for long cable runs due to its balanced transmission.
Does the DI work without mains power?
Power is supplied via phantom power through the XLR connection, with no external power adapter needed.
How to avoid distortion and hum with this DI?
The -15 dB pad reduces the input level when the source is too hot. The ground lift switch helps eliminate hum caused by ground loops. The specified harmonic distortion is 0.001% at 1 kHz and +4 dBu.
What is the frequency response and size of the Pro48?
The frequency response ranges from 20 Hz to 20 kHz. The enclosure measures 108 x 70 x 44 mm and weighs 544 g.
