Zoom AMS-44 4x4 USB-C Audio Interface Loopback

The Zoom AMS-44 is a 4-in/4-out USB-C audio interface built around a simple but effective concept: a hardware switch that instantly reconfigures the interface between two distinct operating modes. In Music mode, the AMS-44 functions as a traditional multitrack interface, routing each of its four XLR/TRS combo inputs as individual channels to your DAW at up to 24-bit/96kHz resolution. This mode also provides two independent headphone mixes, making it practical for tracking sessions where a vocalist and an engineer need different monitor blends. Flip the switch to Streaming mode, and all inputs are summed into a single stereo output optimized for routing into OBS, Zoom, Discord, or any other streaming and communication software — no virtual audio routing or complex software configuration required.

Each of the four inputs features a built-in preamp, with one input specifically designed to handle the high-impedance signal from an electric guitar or bass, eliminating the need for an external DI box in simple recording setups. The hardware loopback function, activated via a dedicated switch on the unit, mixes your device's system audio back into the output stream — essential for streamers who want to include game audio, music, or sound effects alongside their microphone input. Direct monitoring is also hardware-controlled, providing zero-latency monitoring without relying on DAW software settings. The entire unit runs on bus power from its USB-C connection, keeping it portable and desk-friendly, and it works natively with PC, Mac, iOS, and Android without additional drivers on most platforms. For creators who split their time between studio recording and live streaming, the AMS-44 removes the friction of constantly reconfiguring audio routing between those two worlds.
