With excellent sound quality, built-in effects, and a built-in 4 x 4 USB audio interface, the Allen & Heath ZEDi-10FX is a smart mixer for small-format studio and stage applications. Connect four microphones or mono line-level signals, or even two instruments without the need for DI boxes. Two additional stereo channels are available for synthesizers, drum machines, and other line-level sources. Record and play back two channels of 24-bit/96kHz audio via USB without the need for a separate interface. Add reverbs, delays, and combinations of the two with built-in effects processing. Factor in its exceptional build quality, and the compact Allen & Heath ZEDi-10FX mixer stands out in its class.
