Stereo Mixer 1U

Chainable Mono/Stereo Audio Utility Mixer

The Stereo Mixer 1U is a versatile, expandable audio mixer for the Intellijel 1U format. It has two pairs of front panel inputs, each with its own level control, and a mixed output pair. For each input pair, the left channel is normalled to the right channel, for mono operation.
Using 3-pin Link connectors on the back panel, you can chain multiple Stereo Mix 1U’s together in series, giving you the ability to mix together even more inputs, or to create sub-mixes for routing audio around larger systems. You can also these same connectors to patch Intellijel’s Mixup and XY IO 1U modules to these back-panel chains, and you can connect them directly to the ¼” audio jacks on an Intellijel Palette Case, a 7U case with 2nd-generation Audio Jacks Board, an Outs module, or a v2 Headphones 1U.
Because Stereo Mix 1U is designed specifically for audio (and not for CV mixing), it’s AC-coupled, and uses audio-grade, logarithmic attenuators for a smooth, even response across the entire volume range.
