Description
Soundcraft GB4 40ch (40+4/4/2) Mixing Console
The Soundcraft GB4 is a professional analog mixing console engineered for studio recording, live tracking, and post-production work. Built around GB30 microphone preamplifiers with ultra low-noise floors, this 40-channel workhorse delivers the warm, transparent analog character that translates beautifully to tape and DAW, while its 100mm faders and tactile potentiometers provide responsive, intuitive control during tracking and mix sessions. The individually-nutted potentiometers mounted to a steel chassis front panel ensure years of reliable performance in the demanding environment of a professional studio.
Design & Construction
The console measures 1523mm wide × 169mm high × 656mm deep and weighs 37kg, making it practical for permanent studio installations where space efficiency matters. Individual vertically-mounted PCBs fitted to the steel chassis front panel with individually-nutted potentiometers deliver the durability and tactile precision that recording engineers expect when capturing and controlling complex session mixes.
Channel Architecture & Signal Flow
40 mono input channels (via 1/4" TRS and 3-pin XLR) plus 4 stereo input channels accommodate multitrack recording scenarios and instrument combinations, while 8 auxiliary sends, 4 stereo returns, 4 group outputs, and a 7×4 output matrix enable sophisticated mixing architectures for subgroup processing, parallel compression, and creative sends. Direct outputs on all mono channels and insert points on mono inputs, main output, and subgroup outputs allow you to integrate outboard processing seamlessly into your recording and mixing chain.
Key Features
- 40 mono input channels with balanced 3-pin XLR and 1/4" TRS connectivity
- 4 stereo input channels with paired L/R inputs

- 8 auxiliary sends with 4 stereo returns
- 4 group outputs on balanced 3-pin XLR connectors
- 7×4 output matrix for flexible post-fader mixing
- Individually switched 48V phantom power on every mono input
- Direct outputs on all 40 mono input channels
- Insert points on all mono inputs, main output, and subgroup outputs
- 100mm faders for channel-level control
- Integrated LED and VU meter bridge for input and output metering
- THD+N <0.006% (at mic sensitivity -30dBu, +20dBu output @1kHz)
- Dimensions: 1523mm (W) × 169mm (H) × 656mm (D); Weight: 37kg
The GB4 combines clean, transparent analog circuitry with extensive routing options, making it an ideal centerpiece for studios that require proven reliability, low-noise recording capture, and flexible mixing architecture to handle multitrack sessions, overdub workflows, and complex mixing scenarios.

Frequently Asked Questions
What makes the GB30 preamps different, and what noise floor can I expect?
The GB4 uses Soundcraft's GB30 microphone preamplifiers with an ultra-low noise floor of -128dBu E.I.N. at 150Ω source impedance, delivering the transparency and headroom professional engineers expect from a mixing console. This ultra-low-noise floor means your quietest sources—acoustic instruments, vocals, ambient recordings—stay clean and distortion-free, even under heavy processing or at high output levels.
How many inputs and outputs does the GB4 have, and can I integrate outboard gear?
The console provides 40 mono input channels (via XLR and 1/4" TRS) plus 4 stereo input channels, with 8 auxiliary sends, 4 stereo returns, 4 group outputs, and a 7×4 output matrix. Direct outputs on all 40 mono channels and insert points on every mono input, the main output, and subgroup outputs allow you to send audio to external processors (compressors, reverbs, EQs) and bring it back into your mix seamlessly.
Is this console suitable for touring, or is it better for a permanent installation?
The GB4 is built for both: it weighs 37kg and measures 1523mm wide × 656mm deep, making it manageable for tour loads while remaining substantial enough for permanent venues. Individually-nutted potentiometers mounted to a steel chassis front panel and vertically-mounted PCBs ensure durability and reliable performance in demanding live and touring environments.
What EQ and tone-shaping controls are available per channel?
Each channel includes a 4-band parametric/shelving EQ: High (13kHz, ±15dB shelving), Hi-Mid (550Hz–13kHz, ±15dB), Lo-Mid (80Hz–1.9kHz, ±15dB), and Low (80Hz, ±15dB shelving). This gives you precise control over tone from deep low-end correction to bright air, whether you're shaping individual sources during recording or balancing a complex live mix.
Can I use this console for both live sound and studio recording?
Yes—the GB4 is designed specifically for live performance, studio sessions, and theater production. Its warm analog circuitry, transparent audio quality, ultra-low noise floor, and extensive routing make it equally at home capturing clean recordings in a studio or managing complex live mixes at a venue or theater.
