The Allen & Heath GL2 is a compact, general-purpose rackmount mixer designed to deliver professional audio mixing capabilities in a streamlined, space-efficient format suitable for fixed installations and mobile applications. As part of the established GL series, it condenses core features from larger consoles into a manageable unit, making it an ideal front-of-house or monitor mixer for small to mid-sized venues, houses of worship, corporate AV systems, and mobile DJ setups. The mixer provides a comprehensive channel strip architecture with flexible routing, allowing operators to manage multiple live audio sources—such as microphones, instruments, and playback devices—with clarity and control. Its balanced design prioritizes reliable performance and straightforward operation, offering both main and auxiliary outputs to drive power amplifiers, recording devices, or external signal processors.

The channel configuration typically includes a combination of mono and stereo inputs, each equipped with multi-band EQ, auxiliary sends, and routing switches to subgroups or the main mix. High-quality, low-noise mic preamplifiers with switchable phantom power ensure clean gain for condenser microphones, while dedicated stereo line inputs accommodate electronic instruments or media players. The GL2's intuitive layout groups controls logically, with clear metering for both input and output levels to prevent clipping and optimize headroom. Dedicated subgroup faders and master section provide additional mixing flexibility, allowing for grouped control of drum kits, backing vocals, or other related sources before they are sent to the main output.

Built into a robust rackmount steel chassis, the GL2 is engineered for durability and ease of integration into standard 19-inch equipment racks. Its rear panel hosts balanced XLR and TRS connectors for inputs and outputs, along with RCA tape I/O for easy connection to recording or playback devices. The mixer operates on a universal AC power supply, ensuring compatibility in various regions. By offering a reliable blend of essential mixing features, robust construction, and a compact footprint, the Allen & Heath GL2 serves as a versatile and trusted audio hub for applications where space is at a premium but professional audio quality and control are non-negotiable.
