The ART Project Series USBMIX4 is a mixer for microphones, instruments, and line-sources; it also doubles as a USB interface with assignable recording/playback sources. It can operate as a standalone mixer in the analog domain, as well as a one-stop shop for recording podcasts with up to two microphones. The USBMIX4 features two combination inputs that take both XLR and 1/4" connections, allowing you to plug in a microphone, a high-impedance instrument, or a line level source. Two more input channels are provided for 1/4" sources, and a 3.5mm auxiliary input for devices such as MP3 players, tablets, and more.
On the output side, you’re given two balanced, TRS 1/4" jacks for your main mix, as well as TRS terminations for stereo and headphone outputs. If you prefer headphones with a 3.5mm connection point, a compatible jack is on hand for that particular purpose. Channel one sports switchable 48V phantom power, while channel two gives you an impedance switch for HI-Z instrument sources. Both channels give you a pad, gain pots, level pots, pan pots, and a two-band EQ.
The mixer can be bus-powered when used with your computer, though in standalone applications, you can operate the USBMIX4 with the included adapter. The unit works with Mac and PC computers, providing class-compliant, plug-and-play compatibility and obviating the need to download any drivers. A USB cable is provided, as is Audacity—software to handle the recording, editing, and basic mixing of audio material.
