DISC Soundcraft GB8-40 40-Channel Mixer

Full Description

Simultaneous Channel Editing

The Soundcraft GB8-40 40-Channel Mixer has four full-function stereo channels and four stereo returns. There are four mute groups to allow several channels to be muted simultaneously, and stereo recordings of the mix are easier to create thanks to the limiter on both the Record and Alternate stereo outputs. The GB8-40 features 40 inputs: microphone and line level connections, as well as an additional 4 stereo inputs for added convenience. Also featured on the GB8-40 are Soundcraft's GB30 microphone preamplifier's to provide an ultra low-noise floor while maintaining high output gain, a desirable feature for professional audio mixing and mastering scenarios.

Simple Configuration

The Soundcraft GB8-40 40-Channel Mixer supports an output matrix with eleven feeds to four outputs, being fed from the eight group buses and the main L, R and C mono outputs. The rear connector panel slopes, making it easier to configure from the front of the desk, and the integral power supply has a link option for an external back-up PSU. The GB8-40 also features an integrated LED and VU meter bridge to provide a functional level of visual feedback for accurate monitoring of input and output levels, allowing you to stay in control of your audio.

Reliability Ensured

Ruggedly-built, the GB8-40 is designed to be reliable under the most strenuous conditions, with all input modules constructed with individual vertically-mounted PCBs fitted to the steel chassis front panel with individually-nutted potentiometers.
