AVE UC42 USB Audio Interface

The AVE UC42 combines a USB audio interface and compact mixer in a portable, desktop-friendly design. It supports microphones, instruments and line-level sources for mobile recording, live streaming, podcasting, and home or project studio use.

Flexible Recording Inputs

A combo XLR/TRS microphone and line input provides a broad gain range, while +48V phantom power supports condenser microphones. The dedicated Hi-Z input also allows a guitar or bass to be connected directly without an external DI box.

Mixing, Effects and Monitoring

Direct zero-latency monitoring helps performers hear their signal while recording. Built-in reverb and delay offer creative sound shaping, and the 100 Hz low-cut filter helps control unwanted low-frequency noise.

Streaming and Device Connectivity

Bluetooth provides a stereo input for Channels 3/4, while the loopback function supports streaming and webcasting workflows. The interface is powered via USB-C and is compatible with PC, Mac, iOS and selected Android devices.
