Warm Audio Stereo Passive Direct Box

The Warm Audio Stereo Passive Direct Box is 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 -3 to -30 dB pad helps dial in signal volume, and a ground/lift switch helps eliminate ground-loop noise. 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.

PREMIUM STEREO DI BOX

The Warm Audio Stereo DI provides two channels of high-quality direct injection for stereo instruments, including keyboards, synthesizers, and stereo guitar rigs. Designed for both studio and live use, the Stereo Passive DI works perfectly with lower impedance signals like those from keyboards, drum machines, and acoustic-electric guitars

SIGNAL INTEGRITY

With a fully passive design, the Passive Stereo DI operates without external power while still delivering reliable performance and pristine signal conversion. The transformer-based circuit maintains the tonal integrity of the source instrument while providing balanced outputs ideal for professional audio systems.

STUDIO SOUND, PRO FEATURES, ROAD-READY

Built with a durable metal chassis and premium internal components, the Passive Stereo DI is designed to withstand the rigors of both studio installations and touring setups. A negative (3 - 30 dB) pad helps dial in your ideal signal volume, and ground/lift switch helps eliminate ground-loop noise. Stereo DI’s rugged construction ensures dependable operation in any professional audio environment.

IDEAL FOR STEREO INSTRUMENTS

The Stereo DI is specifically designed for stereo instrument sources, with the passive model being ideal for sources such as keyboards, synth modules, and stereo pedalboards. The dual-channel configuration ensures consistent tone and performance across both channels while simplifying stereo signal routing in live and studio environments.

CINEMAG TRANSFORMER EQUIPPED

The Stereo Passive DI features premium CineMag USA transformers that deliver exceptional clarity, rich low-end response, and smooth high-frequency detail. These transformers provide excellent isolation and noise rejection while ensuring the natural character of your instruments are preserved.
