Keyer 44

Description

The KEYER 44 is an audio processing and control system that uses an advanced TI456MHz Dual-Core Chip for DSP giving you an unprecedented opportunity to solve the most complex problems of signal routing & processing. Keyer44 makes mixing, vocal processing, signal routing & room optimisation all these tasks very simple & straight forward.

The Keyer Series DSP helps you to get the most optimised audio performance for presentation and conferencing applications in wherever place you want whether it be in boardrooms, courtrooms, or a resto-bar.
