Radial ProDI 1-Channel Passive Instrument Direct Box

The Radial ProDI is a passive direct box designed for use on stage or in home recording studios, with the ability to handle high output instruments without distortion, and a transformer-isolated output to eliminate noise from ground loops.

The ProDI features a custom-made transformer that is able to handle high levels without saturation. This high-performance transformer has an exceptionally linear frequency response from 20Hz to 18kHz, making it ideal for electronic musical instruments and audio equipment. The ProDI also features a -15dB PAD for high output sources and ground lift switch to troubleshoot noise from ground loops. The ProDI is a great choice for bass and acoustic guitar. 

The ProDI is housed in an extremely rugged two piece 14 gauge steel enclosure with a book-end-designed outer shell that prevents damage to the switches.

FEATURES

• Great sounding, rugged passive DI
• High performance custom-wound transformer
• -15dB PAD for wide range of input levels
• Ground lift switch eliminates ground loop hum
• 'Plug & play' easy-to-use
• Completely passive, no power needed
• Ultra-tough design, to last a lifetime

COOL STUFF

• 15dB PAD allows super-hot inputs such as CD players and headphone outputs to be connected
• INPUT and THRU jacks connect from the instrument and to the instrument amplifier
• XLR balanced 600Ω mic-level output for runs to 1000 feet without appreciable noise
• Ground lift disconnects the ground path to the transformer at the XLR output
• High performance transformer for distortion-free signal transfer and 100% isolation from ground loop hum
• MU-Metal shield for protection against radio frequency and electromagnet interference
• Full bottom pad improves electrical isolation and keeps ProDI from moving around on busy stages
• Book end design creates a protective zone around the jacks and switches
• 14-GAUGE STEEL welded I-beam enclosure makes it impossible to torque the PC board. Eliminates cold solder joints.

APPLICATIONS

• ProDI - the single channel ProDI is perfect for mono instruments like guitar and bass.
