The SCHOEPS AK DMS 3U is a breakout cable for the SCHOEPS Double M/S system. It has an XLR-7F connector leading to three XLR-3M connectors, one for each signal in the array.

In the configuration described by the manufacturer, one shielded six-conductor cable with an XLR-7M output carries the signals from the three microphones: front mid, figure-eight and rear mid. The AK DMS 3U then splits those three signals out again. The official order number is 152401. SCHOEPS also provides official assembly instructions for this cable.
