Its half-width design supports single or tandem 1RU mounting as well as under-table, wall, in-ceiling, and credenza placement using the included accessories. A 4 dBu default input sensitivity makes it easy to drive from any source, and per-channel mode switches set Lo/Hi-Z, high-pass filtering, and gain trim. It is TAA compliant for U.S. federal sales.
