Description

Description

The KEYER 88D 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. The Dante module provides a high bandwidth, low latency, high compatibility, and low-cost solution for network audio transmission. Keyer 88D makes mixing, signal routing, vocal processing, and room optimisation, all these tasks, are very simple and quite straightforward.

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.
