Soundcraft GB8 40-Channel – 8-Bus Analog Live Sound Console

Product Overview

The Soundcraft GB8 RW5697SM is a large-format analog mixing console designed for front-of-house and monitor mixing in mid-to-large performance venues, houses of worship, and broadcast studios. This 40-channel frame with 8 group buses delivers the signal integrity and routing flexibility required for demanding live sound and multitrack recording applications. The GB8 builds on the proven GB4 platform, adding dual-mode topology, a 1kHz oscillator, and an integrated meter bridge — making it one of the most capable analog consoles in its class. Available from Creation Networks, the GB8 is a purpose-built solution for installations where reliability and audio fidelity are non-negotiable.

Product Description

The Soundcraft GB8 40-channel analog mixing console (SKU: RW5697SM) provides 40 XLR microphone and line-level mono inputs alongside 4 full-function stereo input channels (ST1–ST4), each with L/R stereo line inputs and 3-pin XLR microphone connections. The console's 8 subgroup outputs give engineers structured routing to stage monitors, zone amplifiers, or external multitrack recorders, while 8 auxiliary sends cover effects loops, in-ear monitor feeds, and broadcast splits.

At the heart of every channel strip is Soundcraft's GB30 microphone preamplifier and equalizer, an ultra-low-noise design that delivers consistent gain structure whether you're mic'ing a drum kit or a podium. Direct outputs on all mono channels allow pre-fader signals to feed a DAW interface or a broadcast plant without disturbing the main mix. The console's output matrix — 11 sources routed to 4 matrix outputs — adds a further layer of distribution flexibility for delay fills, balcony speakers, or recording splits.

The dual-mode topology allows the GB8 to switch between FOH and monitor mixing configurations, with fader control assignable to either group or aux outputs. Four mute groups enable simultaneous muting of multiple channels — essential for worship transitions or theatrical scene changes. A limiter on the dedicated Record and Alternate stereo outputs simplifies stereo mix capture without introducing extra outboard gear.

The steel chassis features a sloping rear connector panel for front-of-console access during installation, and the integral power supply includes a link option for an external backup PSU — a practical consideration for mission-critical installed applications such as auditoriums and houses of worship. The integrated LED and VU meter bridge provides accurate, at-a-glance metering for all inputs and group outputs.

Key Features

• 40 Mono + 4 Stereo Inputs — 40 XLR/TRS combo inputs plus 4 stereo channels (ST1–ST4) with independent mic and line connections accommodate large-scale input lists.
• 8 Subgroup Outputs — Eight group buses provide structured signal routing to monitors, zone amplifiers, or multitrack recording interfaces.
• 8 Auxiliary Sends — Eight aux sends handle monitor mixes, in-ear feeds, effects loops, and broadcast distribution simultaneously.
• GB30 Microphone Preamplifiers — Soundcraft's low-noise GB30 preamps maintain clean gain structure and high headroom across all mono channel inputs.
• GB30 4-Band EQ — Each mono input channel includes the GB30 equalizer with high, high-mid, low-mid, and low bands for precise tonal shaping.
• Direct Outputs on All Mono Channels — Pre-fader direct outputs enable simultaneous recording or broadcast feed from every input channel.
• Dual-Mode Topology — Configurable for FOH or monitor console operation, with fader control switchable between group and aux outputs.
• 11x4 Output Matrix — Routes group buses and main L/R/C to four matrix outputs for delays, fills, or zone distribution.
• 4 Mute Groups — Simultaneous muting of multiple channels for live event scene changes or worship service transitions.
• Integrated Meter Bridge — LED and VU meters provide real-time metering of all input and output levels at the console surface.
• 1kHz Oscillator — Built-in tone generator for system alignment and line checks.
• Record/Alternate Output Limiter — Dedicated limiter on stereo record outputs protects recordings from clipping without extra outboard equipment.
• Sloping Rear Connector Panel — Ergonomic rear panel angle allows cable termination and system configuration from the front of the desk.
• External PSU Link Option — Integral power supply supports connection of a backup PSU for uninterrupted operation in installed venues.

Typical Applications

• House of worship
• Auditorium

Technical Specifications

Frequently Asked Questions

What is the difference between the GB8 and GB4?
The GB8 adds 8 group buses (vs. 4 on the GB4), a 1kHz oscillator, a larger 11x4 output matrix (vs. 7x4), a limiter on the Record and Alternate outputs, and an integrated meter bridge. It is designed for larger venues and more complex signal routing requirements.

Can the GB8 be used as a monitor console?
Yes. The dual-mode topology allows the GB8 to operate in either FOH or monitor mixing mode, with fader control switchable to aux or group outputs to suit the application.

Does the GB8 support phantom power for condenser microphones?
Yes. Phantom power is provided on the microphone inputs to support condenser microphones and active DI boxes.

What is the output matrix used for?
The 11x4 matrix allows the engineer to route any combination of group buses and the main L/R/C outputs to four independent matrix outputs — typically used for delay towers, balcony fills, broadcast feeds, or zone distribution in installed venues.

Are insert points available on channel inputs?
Yes. Insert points are available on channel inputs, allowing outboard dynamics processors or equalizers to be patched into individual channels.

What does the backup PSU link option provide?
The integral power supply includes a link connection for an external backup power supply unit, providing failover power in mission-critical installations such as houses of worship or broadcast studios.

Is the GB8 suitable for multitrack recording?
Yes. Direct outputs on all 40 mono channels allow pre-fader signals to feed a multitrack recording interface or DAW simultaneously with the live mix.
