Soundcraft GB4-16 - 16-Channel Analog Mixing Console with 7x4 Output Matrix and 8 Auxiliary Sends/4 Sub Groups in Dark Blue Finish

The Soundcraft GB4-16 is a professional 16-channel analog mixing console, designed for high-quality audio performance in demanding environments such as churches, performance venues, and small touring sound systems. Built with the same engineering excellence that has made Soundcraft a trusted name in the audio industry, the GB4-16 combines flexibility, reliability, and superior sound quality into a compact, user-friendly format. Featuring the GB30 mic preamps and EQ circuits designed by Graham Blyth for Soundcraft's 30th anniversary, this mixer provides high-resolution audio with exceptional headroom and clarity.

The GB4-16 offers a host of advanced features, including an innovative 7x4 output matrix, 8 auxiliary sends, and 4 subgroups, allowing for flexible routing and mix control. Each mono input channel is equipped with individually switched 48V phantom power, enabling the use of professional condenser microphones, and all input channels have direct outputs for easy integration with external recording or effects systems. The GB4-16's dual-mode topology, inspired by the MH3 and MH4 desks, allows it to be used in front-of-house (FOH) or monitor applications, giving users the flexibility to control either group or aux outputs via faders.

In terms of construction, the GB4-16 is built to withstand the rigors of live performance and installation environments. The rugged steel chassis features individually nutted potentiometers and vertically mounted PCBs for enhanced durability and ease of maintenance. The sloping rear connector panel makes it easy to configure connections from the front of the desk, whether it's placed on a tabletop or in a rack-mounted setup. The integral power supply comes with an external backup PSU link option, ensuring reliability even in critical applications.

The GB4-16 also includes unique features like 4 mute groups, which allow users to simultaneously mute multiple channels, and a built-in limiter on the record output for creating distortion-free stereo recordings of the mix. Additionally, the 7x4 output matrix provides flexible routing options, feeding signals from the group busses and main L, R, and C (mono) outputs to four separate outputs. The matrix sends allow for creating custom mixes for different zones or applications.

The GB4-16's comprehensive EQ section includes a 4-band GB30 equalizer, with sweepable hi-mid and lo-mid frequency controls, offering precise tonal shaping on each input channel. The console also features 100mm faders for smooth level adjustments and clear, intuitive layout, making it easy to operate even in high-pressure live sound situations. The high-quality TRS jacks and Neutrik XLR connectors ensure reliable signal transmission, while the 12-segment LED meters provide accurate visual feedback for monitoring output levels.

Overall, the Soundcraft GB4-16 is a powerful and versatile mixing console that delivers professional-grade performance in a durable and cost-effective design. Whether used in fixed installations or portable PA systems, the GB4-16 offers the flexibility, control, and sound quality that audio professionals demand.
