Signal path
Learn the route as a block diagram: source, product function, transport, and destination. Select any block to see what enters, what changes, and what leaves.

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 · Audio Interface
Use it as audio interface tracked outside rack rails; follow the manufacturer’s mounting and form-factor guidance.
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: XLR/TRS combo, ¼-inch TRS, usb c, dc barrel. Match connector, direction, and signal type—not shape alone.
