4. FEATURES
• A stereo mixer with 22 input channels (8 monaural inputs and 7 stereo inputs) and 6 output channels (4
monaural outputs and 1 stereo recording output).
• Assignable each input to 6 output channels (OUTPUTs 1 – 4, REC OUT L/R) individually.
• Adjustable for intelligible sound output (ARC function) by automatically creating a sound field compensation
filter (ARC filter).
• Automatic feedback suppressor (FBS function).
• Stereo inputs muted automatically by detecting the monaural input signal (Automatic Mute function).
• Monaural inputs with a built-in analog gain control circuit (0 to +60 dB).
• Monaural inputs capable of supplying phantom power (+24 V, 10 mA).
• Stereo inputs with a built-in analog trim control circuit (–∞ to 0 dB).
• Volume adjustable with 60 mm (2.36") faders.
• Each function settable at the M-864D using its front-mounted switches and faders.
• Advanced settings using the supplied M-864D PC Software via LAN.
• Designed for use in conjunction with the optional Remote Control Panels ZM-9011, ZM-9012, ZM-9013, and
ZM-9014 (collectively referred to as “ZM Remote controller” in this manual), enabling volume control, channel
ON/OFF, and Preset memory recall.
5. HANDLING PRECAUTIONS
• The supplied power supply cord is designed for exclusive use with this unit. Never use it with other equipment.
• Install the unit in locations where the temperature is between 0 and +40 °C (32 and 104°F) and the moisture
is less than 90% (no dew condensation must be formed).
• The M-864D is a precision audio component. To prevent failure, avoid locations where the unit may be
exposed to strong shocks or vibrations.
• To clean, be sure to first switch off the unit's power, then wipe with a dry cloth. When the unit gets very dirty,
use a cloth damped in a neutral cleanser. Never use benzene, thinner, alcohol, or chemically-treated cleaning
cloth because such volatile liquids could deform or discolor the unit.
6. INSTALLATION PRECAUTIONS
• Be sure to install and connect the unit before the connection to the AC mains outlet. Remove the unit's power
supply cord from the AC mains outlet when uninstalling or disconnecting the unit.
• The socket-outlet shall be installed near the equipment and the plug shall be easily accessible.
