The VMX300 has 3 dual-input channels for connection of up to six stereo sources. Channel 1 features a built-in ULN mic preamp and an auto talkover function for your mic; channels 2 and 3 are laid out for phono and line-level signals. Each stereo channel features a gain control, an effective 3-band kill EQ with up to 32 dB of attenuation and a 45-mm ULTRAGLIDE fader with a 3-way curve switch. Other features are the XPQ 3D surround effect with ON/OFF button and depth control, as well as an automatic BPM counter with Tempo Difference and Time Offset displays. A continuously variable crossfader curve control plus a crossfader reverse switch give you plenty of power for mixing tricks.
