Two mono channels and two stereo channels with separate monitor and record stereo outputs as well as a stereo return. Two headphone outputs make it an excellent utility mixer for tracking and performance. The 3 channel shelving EQ is nice with a musical sound. The mixer also has RIAA inputs for turntables as well as a direct instrument input that sounds GREAT on my bass guitar - I love the tone it produces!
Highly recommended as a general purpose/utility mixer for any studio!
