The Allen & Heath GL2400-24 is a professional-grade, 24-channel live sound mixing console renowned for its robust construction, intuitive layout, and versatile dual-function capabilities. Designed for touring, installed sound, and demanding live applications, the mixer provides a comprehensive channel strip for each input, featuring high-headroom, low-noise mic preamplifiers, 3-band EQ with sweepable mid-frequency, and dedicated aux sends. The "dual-function" design refers to its flexible monitoring system, where the first two auxiliary outputs can be switched between pre-fader (for monitor sends) and post-fader (for effects sends) operation on a per-channel basis, offering significant routing flexibility from a compact frame. This makes the console equally adept at managing front-of-house mixes and separate monitor mixes from a single surface.

The mixer's center section includes master controls for the four subgroups, stereo L/R mix, and a dedicated mono output. It features comprehensive metering, talkback functionality, and a range of connectivity options on the rear panel, including balanced XLR and TRS line inputs, insert points on the first 16 channels, and XLR outputs for all main mixes. Built on a steel chassis with a durable, scratch-resistant surface, the GL2400-24 is designed to withstand the rigors of the road while providing reliable performance show after show. Its logical, ergonomic design allows engineers to work quickly and confidently in high-pressure live environments.

Balancing professional features with straightforward operation, the GL2400-24 serves as a workhorse console for mid-sized venues, houses of worship, theaters, and corporate events. Its combination of sonic quality, routing flexibility, and rugged build has made it a long-standing favorite among sound engineers who require a dependable, no-nonsense mixer capable of handling a wide variety of input sources and delivering clear, powerful mixes.
