Warm Audio Transformer- Balanced 2-Channel Passive Direct Box

Warm Audio Stereo DIs include active and passive two-channel direct boxes designed for stereo instruments, including keyboards, synthesizers, guitar processors, and stereo pedalboards. Built with premium CineMag USA transformers, both models preserve the tonal character of your instrument while delivering clean balanced signals to mixers, audio interfaces, and PA systems. A negative (3 - 30dB) pad helps dial in signal volume, and a ground/lift switch helps eliminate ground-loop noise. The Active Stereo DI provides additional headroom and selectable active circuitry per-channel for lower output instruments and stereo rigs. The Passive Stereo DI offers transformer-isolated signal conversion ideal for high-output sources like drum machines, playback rigs, and modelers feeding FOH consoles or recording systems.
