Ultra Compact Passive DI
Radial Engineering's ProDI is a high-quality, single-channel, ultra-compact passive direct box designed to handle high-powered instruments without distortion.
It has a custom transformer that can handle high levels without saturation and has a linear frequency response from 20Hz to 18.5kHz, making it ideal for electronic musical instruments and audio equipment. Also included is a -15dB pad for large power supplies and a ground switch for a ground loop noise problem.
The 14-gauge welded I-beam inner frame and outer shell greatly reduces PC board torque. The full bottom anti-slip rubber pad does double duty, protecting against electric shock and holding the ProDI in place.
