M-864D
DIGITAL STEREO MIXER
A Fader-type Digital Stereo Mixer
for Multi-Purpose Venues
Permitting Analog-feel Parameter Setting
As Well As PC or LAN Operation
TOA's proprietary digital technologie
adjustment for events of all kinds.
TOA's new 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.
Digital Stereo Mixer M-864D
Optimal sound control features
• Automatic Resonance Control (ARC) measurement and processing algorithm that optimizes speech
and sound clarity for individual acoustic environments
• Feedback Suppressor (FBS) function that eliminates feedback caused by carrying the microphone
from place to place
• Automatic stereo input mute (Auto Mute or Ducker) function that mutes
stereo input automatically when detecting a monaural control signal
Easy, convenient operation functions
• Analog-feel fine-tuning by slider control
• Front-mounted stereo input allowing connection of digital audio player
• Preset memory enabling operators to store user-specified settings in
response to specific needs
• Interconnection of up to five M-864D units in preset memory system via LAN
• Optional remote control panels (ZM-9011/9012/9013/9014) permitting
convenient remote operation and featuring an assign function supporting
assignment of such settings as volume control, channel ON/OFF,
matrix switching and preset memory recall to specified buttons.
Response to exacting user requirements
• Dedicated GUI software facilitating higher-precision parameter
setting adjustment on PC via Ethernet LAN
Flexible configuration choices
• Stand-alone installation (4U rack-mountable)
• Finer speaker setting possible when used in combination
with optional Digital Speaker Processor DP-SP3
ies enable optimal sound quality
