Low inrush current ensures that the mains breaker will not trip when several power amplifiers are
turned on simultaneously.

Mounting
Unpacking
Carefully open the shipping carton and check for any noticeable damage. Every amplifier is tested and inspected
before leaving the factory and should arrive in perfect condition. If any damage is discovered, please notify the
shipping company immediately. Only the consignee may institute a claim with the carrier for damage incurred
during shipping. Save the carton and packing materials for the carrier's inspection.
Mounting
Free airflow from front-to-rear of the amplifier must be possible. Therefore, no doors or rack-lids should be
mounted in front of or behind the amplifiers.
Amplifiers may be stacked directly on top of each other. There is no need for spacing in between units, though this
might enable more convenient installation of cabling on the rear panel.
It is recommended that rear supports be mounted for maximum long-term stability. Rear support brackets are
included.
Cooling
The amplifier uses a forced-air cooling system with air flow from front to rear, maintaining a low operating
temperature within defined limits. Front-to-rear airflow is preferred as cooler air is present at the front in nearly
all applications. Never attempt to reverse the airflow.
Make sure that there is an adequate air supply in front of the amplifier, and that the rear of the amplifier has
sufficient space to allow the exhaust to escape. If the amplifier is rack-mounted, do not use covers or doors on the
front or rear of the rack.
Should a heat sink overheat, the temperature sensing circuits will mute the overheating channel. If the power
supply overheats, another sensing circuit will mute all output channels until the power supply cools to safe
operating temperature.
Always make sure that the dust-filters behind the detachable front panel are clean to ensure maximum
。
possible airflow.
NOTE
Operating Voltage

、
The label placed to the right of the mains cable on the rear of the amplifier indicates the AC mains voltage for
which the amplifier is wired and approved: 110 V or 220 V. Connect the power cable only to the AC source type
referred to on the label. The warranty will not cover damage caused by connecting to an incorrect type of AC
mains.
