Fully featured audio mixer with 4 mono input channels, a stereo line input, stereo Aux input and a further minijack stereo input. Each mono mic/line channel has a combo XLR/jack input with +48V phantom power switchable in pairs for the XLR inputs. Each mic/line channel has a Gain control for matching the input source and a low-cut switch to filter out rumble or handling noise from microphones. Each mono channel also has High/Mid/Low EQ controls, Aux out level, FX level and Pan control. The onboard foot-switchable DSP effects engine has 99 presets for delay, reverb and modulation effects, each of which can be adjusted using two parameter controls. An onboard Bluetooth receiver has an illuminated pairing button and independent volume control. The USB type-A port on the top panel is for playback of audio files or can be used to record the main outputs to a USB storage device or as an external audio device when connected to a laptop. Main output is served by left & right XLR, in addition to 6.3mm monitor and headphone outputs and the Aux send & stereo return loop. The CMB-series offers large console features in a more manageable format for live performers and project studio recordists.
