The GB4-40 is 40-channel, 4-bus console designed and constructed to ensure rugged reliability under stressful tour conditions. All input modules have individual vertically-mounted PCB's fitted to the steel chassis.
It is designed for performance venue installation or small touring system applications. The dual-mode topology allows it to to be used for FOH or monitor duties, with fader control of group or aux outputs.
Although largely conventional in layout, the GB4 does have some unique mechanical features. The rugged steel chassis has a sloping rear connector panel so that it is easier to configure from in front of the desk, while the integral power supply has a link option for an external backup PSU.
4 mute groups allow several channels to be muted simultaneously. Another unique feature is the limiter on a set of dedicated record outputs that makes it easier to create a stereo recording of the mix.
The console also features an output matrix with 7 feeds to 4 outputs, fed from the group buses and main L, R, and C (mono) outputs.
The GB4 offers a comprehensive set of functions in a small and cost-effective footprint, and delivers the high performance and reliability you expect from a Soundcraft product.
