This compact format audio mixer is ideal for small events, studios and live streaming. It has 2 mono mic/line input channels and a stereo line input for a total of 4x inputs. Each mono mic/line channel has a combo XLR/jack input with individually switchable mic/instrument impedance and +48V phantom power for the XLR.

Input channels have High/Low EQ and Pan controls. There is a built in delay which can be added to the mono channels and blended in using the 'effects level'.

The stereo output is delivered on a pair of balanced XLR connectors and offers very low noise operation for high quality studio or live performances.

Bluetooth is built in allowing a device to connect to the mixer to play music such as backing tracks. An internal player/recorder with backlit display can accept a USB memory stick containing compressed audio files in various formats.

There is a dedicated volume control for the main output, headphones and media player.
