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.

The GB4 has a standard layout for intuitive operation. It also features a GB30 Mic Preamplifier and Equalizer that enables high-resolution adjustment over a wide gain range of 55 dB. It comes in two variant models, differentiated by the frame sizes:

  • 24 channels
  • 48 channels

Each channel features 4 full-function stereo channels and 4 stereo returns.

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.

More about Soundcraft’s GB Analog Mixers

Soundcraft’s acclaimed GB Series of analog mixers boasts high-quality engineering, innovative design, and painstaking details.

Rugged and reliable, its mechanical construction has been crafted to endure strenuous conditions, so you get the best performance out of your audio mix no matter how much punishment you give your gear.
