DISC Soundcraft GB8-48 48-Channel Analog Mixer

Full Description

Premium-Grade Live Mixer

The Soundcraft GB8-48 48-Channel Mixer is designed for a range of live applications and installations, making it perfect for everything from houses or worship to live music venues and more. The highly rugged and durable steel chassis is perfect for live installations, easily withstanding the rigors of extensive live use. Its dual-mode topology is based on the success of the Soundcraft MH3 and MH4 desks, allowing you to use the GB8 for FOH or monitor duties with fader control of group or AUX outputs. The four full-function stereo channels also included four stereo returns for added convenience, perfect for small touring sound systems and more. Also included is a 4-band GB30 EQ for precision control over your frequency bands, allowing you to easily create professional mixes for live performances.

GB30 Microphone Preamps

The Soundcraft GB4 series features custom GB30 microphone preamps and EQ, delivering exceptional audio quality throughout. The GB30 microphone preamps are specially designed by Graham Blyth, delivering a warm yet articulate tone that captures every nuance of the original source material. Reminiscent of vintage microphone preamps, the GB30 preamplifier circuit is airy yet deep within its sound palette, creating exceptional harmonics and overtones. The ultra low-noise floor and high output gain ensures optimal clarity and punch, cutting through even the busiest of mixes.

Intuitive Layout & Design

The Souncraft GB8-48 features a wide range of design aspects implemented to improve the workflow and performance of the mixer. The dual purpose console features individually switched 48V phantom power on every mono input module, allowing you to utilise studio-grade equipment such as condenser microphones and more. The integrated Meter Bridge features accurate VU meters for left, right and centre outputs, giving you highly accurate visual feedback with the classic vintage style found in older mixers. The all metal TRS jacks and Neutrik XLRs are designed for optimal performance and signal transference, ensuring the best possible audio quality at all times. A limiter on the Record Output and Alternative Stereo Output is designed to reign in the dynamics of your mix after.
