Soundcraft GB2 - Mixing console with 4 configured group buses and a comprehensive 6 x 2 matrix

Soundcraft GB2 – Analog mixer with 4 group buses and integral 6×2 matrix

The Soundcraft GB2 is a high-performance analog mixing console specifically designed for fixed sound installations and audio-visual applications. Available in 16, 24, and 32 mono input chassis, all with two additional stereo inputs as standard, it combines Soundcraft’s reputation for quality with the versatility of 6 aux sends, 4 subgroup buses configured in 2 stereo pairs, and a comprehensive 6x2 output matrix. Each channel incorporates the GB30 preamplifier and precision GB30 EQ, as well as switchable +48V phantom power and a 100Hz high-pass filter, offering comprehensive tonal control and signal cleanliness in demanding environments. The design maintains panning within subgroups and allows the stereo width of the mix matrix to be adjusted independently, from full stereo to mono, optimizing the distribution of the main and sub mixes without the need for external equipment.

Main features

• 16, 24 and 32 mono channel formats , with 2 full stereo channels per model.
• 4 subgroup buses configured as 2 stereo pairs, with stereo width control independent of panning.
• Integral 6×2 matrix for sending combinations of group and L/R/C mix signals to auxiliary outputs or secondary zones.
• 6 configurable pre/post auxiliary sends , ideal for monitoring or external processors.
• GB30 Mic Pre and 4-band EQ on each mono channel, designed for low distortion and musical response.
• Switchable +48V phantom power per channel and 100Hz high-pass filter to eliminate unwanted noise.
• 2 stereo inputs with separate microphone and line circuits; selecting line mutes the microphone.
• Direct outputs on each mono channel, pre/post selection, for recording or external processing.
• 100mm high-precision faders for smooth and stable adjustment.
• Dedicated recording output with internal limiter, which prevents clipping in stereo captures.

• Can I use line inputs on the stereo channels? Yes; when you select LINE on the local channel, the line signal replaces the microphone.
• Does the console include a peak protection on the recording output? Yes; it has an internal limiter that prevents clipping in stereo recordings.
• What rack dimensions does it occupy? It's a 3U 19" rack mixer with a standard width and a depth of 400 mm.
• Does it need an external power supply? No; it has an internal universal auto-ranging PSU.
