18. ARC FUNCTION SETTING
18.1. What is the Automatic Resonance Control (ARC) Function?
ARC stands for Automatic Resonance Control.
It is a function that automatically creates a sound field compensation filter (ARC filter) to improve sound clarity
by automatically measuring the inherent acoustic characteristics in architectural space.
18.2. Notes on ARC Function Setting
• Before operating the ARC function, check that sound is actually output from the speakers after installation
and connection completion.
• The ARC filter is set to the output channels to which this filter was assigned at the time of ARC measurement.
• When the ARC filter has already been set, it is overwritten by the newly set filter after completion of ARC
measurement.
• To reset the ARC filter, disable the ARC function. (See p. 35.) In this case, all the ARC filters assigned to
the output channels are initialized. Individual filters cannot be reset.

Rack
Power amplifier
Blank panel
M-864D
• Elevated Operating Ambient - If installed in a closed or multi-unit rack
assembly, the operating ambient temperature of the rack environment
may be greater than room ambient. Therefore, consideration should be
given to installing the equipment in an environment compatible with the
maximum ambient temperature (Tma) specified by the manufacturer.
• Reduced Air Flow - Installation of the equipment in a rack should be such that the amount of air flow required
for safe operation of the equipment is not compromised.
• Mechanical Loading - Mounting of the equipment in the rack should be such that a hazardous condition is not
achieved due to uneven mechanical loading.
• Circuit Overloading - Consideration should be given to the connection of the equipment to the supply
circuit and the effect that overloading of the circuits might have on overcurrent protection and supply wiring.
Appropriate consideration of equipment nameplate ratings should be used when addressing this concern.
• Reliable Earthing - Reliable earthing of rack-mounted equipment should be maintained. Particular attention
should be given to supply connections other than direct connections to the branch circuit (e.g. use of power
strips)."
• Température ambiante élevée - si l’appareil est installé dans un bâti fermé ou en même temps que d’autres
appareils, la température à l’intérieur risque de devenir supérieure à la température ambiante. Par conséquent,
veiller à installer l’équipement dans un environnement compatible à la température ambiante maximum
spécifiée par le fabricant.
• Débit d’air réduit - L’installation de l’équipement en bâti ne doit pas compromettre le débit d’air nécessaire à
une utilisation sûre de l’équipement.
• Charge mécanique - Le montage de l’équipement en bâti ne doit pas entraîner de danger dû à une surcharge
mécanique inégale.
• Surcharge du circuit - rester vigilant lors de la connexion de l’équipement au circuit d’alimentation et
aux conséquences d’une surcharge des circuits sur la protection contre les surintensités et les câbles
d’alimentation.
Tenir compte des indications de la plaque nominale de l’appareil.
• Sécurité de la mise à la terre. Veiller à toujours garantir l’intégrité de la prise de mise à la terre. Faire

25.3.1. Cable length for wiring
Cable length and the number of the connectable ZM Remote controllers differ depending on the wiring method.
[Star wiring]
This is a method to directly connect each ZM Remote controller to the M-864D.
Perform wiring installation so that the total cable length between the M-864D and each ZM Remote controller
does not exceed 800 m (870 yd).
Example: Up to 16 ZM Remote controllers can be connected if the total cable length between the M-864D and
each ZM Remote controller is within 800 m (870 yd).
Perform wiring installation so that the total cable length between the M-864D and each ZM Remote
controller does not exceed 800 m (870 yd).
