This Studer Stereo Balancing Unit—loaded with three original 2-channel modules (Part No. 1.915.904.81)—offers six channels of simultaneous balanced-to-unbalanced and unbalanced-to-balanced conversion. No menus, no latency, just clean analog interfacing the way it was meant to be.
Ideal for bridging the gap between vintage unbalanced gear and modern balanced systems, this unit shines in hybrid workflows: patch in tape machines, tame noisy outputs from old console modules, or retrofit balanced direct outs from insert sends. Especially powerful when wrangling console inserts or integrating outboard into DAW-based setups with finesse.
Built like only Studer could—quiet, transparent, and engineered to last. A studio utility box you’ll wonder how you lived without.
