The Soundcraft GB4 Series 24-channel console is a robust and versatile analog mixer built for the demands of mobile live sound and permanent installation. Its specification of "24x4/4/2" indicates 24 input channels, 4 subgroup buses, 4 auxiliary sends, and a stereo main output complemented by a 2-band matrix. This routing flexibility empowers engineers to manage small to medium-sized productions efficiently, allowing for logical subgrouping of instruments, creation of separate monitor and effects mixes, and independent control of additional speaker zones via the matrix outputs. The console is founded on Soundcraft's high-quality, low-noise microphone preamplifiers and a discrete Class-A master output section, ensuring transparent and powerful audio reproduction.

Each input channel is equipped with a comprehensive 4-band equalizer, featuring two swept mid-frequency bands for precise tonal shaping—an essential tool for ring-out and feedback control. A switchable 75 Hz high-pass filter helps clean up channels by removing subsonic rumble. The four auxiliary sends are configured as two pre-fader (typically for monitor mixes) and two post-fader (ideal for effects), with all four being stereo-capable to double their utility. The intuitive, logically segmented layout, combined with clear metering and a responsive solo system, facilitates a fast and confident workflow even in high-pressure environments.

Housed in a durable steel chassis with a reliable internal power supply, the GB4 24-channel is engineered for both touring toughness and installed reliability. Its comprehensive I/O, including direct outputs on every channel and extensive insert points, makes it a capable centerpiece for a wide range of applications. Striking an excellent balance between professional features, sonic integrity, and operational simplicity, this mixer is a trusted choice for bands, rental companies, and venues requiring a dependable and sonically superior analog console.
