Fitting a comprehensive set of functions into a compact, cost-effective build, the GB8 from Soundcraft is a high-performance analog mixer. It’s ideal for medium-sized installations such as houses of worship or performance venues, but it’s also a great choice for small touring sound systems. In addition, GB8 boasts dual-mode topology equips you for fader control of group or aux outputs, so you can also use this mixer for FOH or monitor duties.
Some of GB8’s features include a rugged steel chassis with a sloping rear connector panel, allowing it to be easily configured from the front of the desk, along with an integrated power supply with a link option for external PSU backup. Four mute groups allow you to mute several channels at the same time. A limiter on both the Record and Alternate stereo outputs lets you create a stereo recording of your mix using a selected set of record outputs. An output matrix contains 11 feeds to 4 outputs, being fed from the group busses and main L, R, and C (mono) outputs. A 1kHz oscillator and a meter bridge with 3 LED meters that emulate the ballistics of VU meters.
