Tags: 4 Channel mixers

Notes: Compact format audio mixer with 2, 4 or 6 mono input channels, a stereo line 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/Low EQ controls and an FX level control. Pairs of mono channels can be linked to act as a stereo left + right pair as required. 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 deviceor as an external audio device when connected to a laptop. Output is delivered to a pair of balanced XLR connectors to provide low noise operation for high quality studio or live performances.
