Union Audio orbit.4 LE 4 Channel Rotary Desktop Mixer With 3 Band Isolator

For DJs and producers requiring four channels, the Union Audio orbit.4 LE builds on the heritage of its smaller sibling, adding two extra channels and dual microphone inputs in a slightly larger format.

The versatile orbit.4 LE is equally at home in bars and clubs as it is as the centerpiece for the discerning home producer. Engineered for a superior DJing experience, the mixer features four fully independent channels, each with high-quality phono pre-amplifiers and line inputs, a variable-Q high-pass filter, FX Send with pre/post switching, and precise Alps rotary faders.

The Master section provides separate level controls for Master Out, Booth Out, and Aux Return, with accurate signal monitoring via two backlit custom analogue VU meters. A powerful headphone amplifier supports both Split Cue and Cue/Mix monitoring, with front-panel 1/4 inch and 3.5 mm headphone outputs for maximum versatility.
