The Soundcraft GB4 Series 32-channel mixer is a versatile and powerful analog console designed for serious live sound applications in medium to large venues. Its "32x4/4/2" specification denotes 32 input channels routed through 4 subgroup buses, 4 auxiliary sends, and a stereo main output, with an additional 2-band matrix for further system distribution. This flexible architecture provides exceptional control for engineers, allowing them to subgroup drums, vocals, or other instrument sections, create multiple monitor mixes, and feed separate zone or delay speakers via the matrix. The console is built around Soundcraft's respected low-noise microphone preamplifiers and a discrete Class-A output stage, ensuring a transparent and powerful sonic performance from input to output.

Each input channel is equipped with a comprehensive 4-band equalizer featuring two swept mid-frequency bands, granting precise tonal shaping capabilities for solving difficult feedback problems or enhancing particular instruments. A switchable 75 Hz low-cut filter helps clean up channels by removing unwanted low-frequency rumble. The four auxiliary sends are configured as two pre-fader (ideal for monitor mixes) and two post-fader (perfect for effects sends), all of which are stereo-capable, effectively doubling the number of mono mixes available. The intuitive layout, with clear section divisions and comprehensive metering, promotes an efficient and confident workflow.

Housed in a rugged steel chassis with a robust internal power supply, the GB4 is engineered for reliability in demanding touring and installation environments. Its direct outputs on every channel and extensive connectivity options make it a central hub for complex systems. Balancing professional-grade audio, extensive routing, and straightforward analog operation, the Soundcraft GB4 Series 32-channel console stands as a reliable and sonically superior workhorse for touring engineers, rental companies, and fixed installations alike.
