3. GENERAL DESCRIPTION
The M-633D is a stereo mixer with digital signal processing functions such as Automatic Resonance Control
function (ARC), Feedback Suppressor function (FBS), Automatic Clipguard function (ACG), and Automatic Mute
function (AUTO MUTE).
It can be mounted in an EIA component rack (1U size*).
* 1U size = 44.5 mm (standard size)
4. FEATURES
• A stereo mixer equipped with 12 input channels (6 monaural inputs and 3 stereo inputs), and 6 output channels
(2 monaural outputs, 1 stereo output, and 1 stereo recording output).
• Assignable each input signal to 3 output channels individually (MONO OUT 1, MONO OUT 2, and STEREO
OUT).
• Sound reproduction owing to automatic clarity control (ARC function).
• Automatic feedback suppressor (FBS function).
• Automatic input sensitivity control when an excessive input signal is applied to the monaural input (ACG
function).
• Stereo input muted automatically by detecting the monaural input signal (Automatic Mute function).
• Input sensitivity switchable to either –10 dB or –46 dB for the monaural inputs.
• The monaural inputs capable of supplying phantom power (+24 V, 10 mA).
• Assignment switch cover for protecting the assigned setting positions of each input usable as a signal name
writing plate.
• Easy function settings using the front and rear panel controls.
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-633D 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.
