The MultiMix 4 USB mixer has four input channels, all of which can accept a 1/4-inch line input. You can plug XLR microphones into channels one and two, including condensers thanks to the mixer's switchable 48V-phantom power supply. You can also plug a guitar or bass directly into channel one's switchable high-impedance input.
Channels one and two offer switchable high-pass filtering at 75Hz to eliminate low-frequency rumble, handling and wind noise. Each channel has an independent pan control and channels one and two provide high and low-shelving EQs. Channels one and two have independent gain trims, while channels three and four are configured as a stereo pair at the level and pan controls.
