The Soundcraft GB4 24-Channel High Performance GB Series Console Audio Mixer combines a comprehensive set of features with compact design and exceptional audio performance, making it perfect for installations and small touring sound systems. With a focus on reliability and ease of use, the GB4 is engineered to meet the demands of live sound mixing while providing the performance you expect from a Soundcraft product.
Designed by Graham Blyth to celebrate Soundcraft’s 30th anniversary, the GB4 features the renowned GB30 microphone preamps and 4-band GB30 EQ section, ensuring pristine audio quality for all your live sound needs. The mixer is available in frame sizes ranging from 16 to 40 channels, and this 24-channel version is well-suited for smaller venues, churches, performance spaces, or touring systems.
The GB4’s dual-mode operation allows it to function as both a front-of-house (FOH) or monitor mixer, with the flexibility to switch between the two modes with the push of a button. This versatile mixer also includes 7 buses (4 subgroups and left, right, and center main mixes), 8 auxiliary sends with flexible pre/post switching, and 4 mute groups for simultaneous muting of multiple channels.
A standout feature is the 7×4 matrix output system, which allows you to create separate sub-mixes of the left, right, center, and group outputs, giving you precise control over your mix. The rugged steel chassis with a sloping rear connector panel makes it easier to configure the system, while the integral power supply includes a link option for an external backup PSU, ensuring peace of mind during live events.
The GB4 also features LED meters and a limiter on the dedicated record outputs, simplifying stereo recording of the mix. The durable construction and high-end components make this mixer a reliable solution for professional sound engineers, offering both high performance and cost-effectiveness in a compact footprint.
