Soundcraft GB2 High Performance Analog Mixer

The GB2 from Soundcraft is a high-performance analog mixer that features 4 group busses configured as 2 stereo subgroups, along with a built-in 6 x 2 matrix. Super compact and streamlined, this member of the GB Series is intended for installations and AV setups that need just the basic mixing functions.

Just because it’s basic doesn’t mean it’s inflexible. Choose from three available frame sizes: 16, 24, or 32 mono inputs. Each variant comes with 2 stereo inputs. GB2 models also boast a GB30 Mic amplifier, enabling high-resolution adjustment over a wide gain range of 55 dB. Other features include 6 Aux busses, 2 stereo input channels with separate mic and line inputs, 4 subgroups for adjusting the width of the stereo signal across the stereo mix, and channel pan settings.
