Digital stereo mixer
The M-864D digital stereo mixer maintains the basic functionality and operability of its predecessor, the M-633D, but adds such versatile features as analog-feel fader operation, 8 monaural and 7 stereo input channels, remote controller operation and fine-tuning of settings with GUI software.
With its release, TOA has made the clear sound achieved by its proprietary resonance control technology available for use in hotel banquet rooms, multipurpose halls and other facilities that host events of various types.
