This compact 4-channel audio mixer with USB interface is suited for universal applications, e.g. for audio recording on the computer. The mono input channel allows connecting a (phantom-powered) microphone; the stereo input channel allows connecting an audio source with line signal level. In addition, the mixer is provided with connections for a recorder and headphones. The mixed signal is sent to the output via 1⁄4-inch jacks and the USB port. It is also possible to use the USB port as an input to transfer audio data from the computer to the mixer. When connecting the mixer to a computer, power is supplied via the USB connection. When operating the mixer without a computer, either use a suitable power supply unit with USB connection to operate the mixer.
