The Countryman DT85S Type 85S Stereo Direct Box is an active, two-channel DI box designed to handle stereo line-level signals from electronic sources such as keyboards, CD/DVD players, computers, and DJ mixers. It provides independent channels to maintain the stereo image when connecting to a professional audio system, converting unbalanced or balanced high-impedance stereo outputs into balanced, low-impedance microphone-level signals suitable for long-distance transmission to mixing consoles or recording interfaces. This unit is essential in live sound, broadcast, and studio environments where preserving stereo separation and fidelity from electronic sources is critical, preventing signal loss and noise interference.

Housed in a robust, all-metal chassis, the DT85S is built for durability in professional touring and installation applications. Each channel features its own Neutrik combo XLR/TRS input jack and a balanced XLR output. The active circuitry is powered by phantom power (48V) from the connected mixer, ensuring reliable operation without batteries. Key features include a ground lift switch per channel to eliminate hum from ground loops and a -20dB pad switch to prevent input overload from high-output sources. The thoughtful design also includes stereo link capability for simplified gain control when needed.

The Countryman DT85S is prized for its transparent sound quality, wide frequency response, and high headroom, accurately passing the source signal without coloration. Its dual-channel design in a single, compact unit saves space on stage or in the rack compared to using two mono DIs. For audio engineers who require a reliable, high-fidelity solution for integrating stereo electronic audio sources into a professional balanced audio system, the DT85S Stereo Direct Box is an industry-respected tool.
