Compatibility
Treat connector names as the start of the check—not the answer. These are the boundaries that determine a complete working path.
Best fit · Digital Mixer
Use it when 4U and 161 mm of depth fit the case.
Plan the companion path
Complete the path with upstream and downstream gear that matches connector, direction, signal type, protocol, and wiring standard.
Connector boundary
Documented connectors: ¼-inch TRS, XLR female, XLR male, RJ45. Match connector, direction, and signal type—not shape alone.
