Soundcraft GB Series — buyer FAQs
What models make up the Soundcraft GB Series and how do they differ?
The GB Series comprises four models: the GB2, GB2R, GB4 and GB8. The GB2 is a full-format desk available in 16, 24 and 32 mono input frames with 4 group busses and a 6x2 matrix. The GB2R is a 19-inch rack-mountable version in 16-channel and 12.2-channel formats. The GB4 and GB8 are the larger-format desks, scaling up to 40 and 48 channels respectively, both offering dual-mode topology for FOH or monitor duties.
Who makes the Soundcraft GB Series and where does it fit in their console range?
The GB Series is made by Soundcraft, a British professional audio brand founded in 1973 and part of Harman International since 1988. Within the Soundcraft line-up the GB Series spans from affordable compact options to larger professional desks, and shares its styling with other consoles in the range such as the MH4, MH3 and LX7ii, reflecting a consistent family design.
What is the dual-mode topology on the GB4 and GB8 used for?
The dual-mode topology on the GB4 and GB8 allows either desk to be used for front-of-house or monitor duties, with fader control of group or aux outputs in each mode. This flexibility makes them suitable for venues or touring setups where one console may need to serve different roles. The GB4 also includes an output matrix with seven feeds to four outputs, adding further routing capability.
What mic preamp and EQ does the GB Series use across its models?
All models in the GB Series use the GB30 mic preamp and GB30 equaliser on input channels. The GB2R additionally provides switchable 48V phantom power on every mic input, a 100Hz hi-pass filter and direct outputs on every channel. This consistent preamp and EQ platform runs across the GB2, GB2R, GB4 and GB8, giving the family a unified signal-path character regardless of frame size.
What should I check when buying a used Soundcraft GB Series console?
Check which specific model and frame size is listed, as channel count, bus configuration and features vary considerably across GB2, GB2R, GB4 and GB8. Confirm the condition of faders (the GB2R uses 100mm faders), phantom power switching and any included accessories.
