Four-channel mixing
The M6 USB provides four full mixer channels with gain, three-band EQ and LED metering. Any channel can be assigned to either side of the crossfader, which is useful when combining several players or turntables in one setup.
USB audio for playback and recording
The USB connection allows audio from a computer to be mixed through the hardware and also allows the mix to be recorded back into compatible recording software. The USB audio connection is class compliant.
Turntables, line sources and microphones
Multiple phono and line inputs make the mixer suitable for turntables, media players and other analogue sources. A dedicated XLR microphone channel is joined by a second microphone input on channel four.
Professional outputs
Balanced XLR main outputs allow direct connection to professional sound systems, while separate RCA Master, Booth and Record outputs provide additional routing for monitors and recording devices.
