Installation and operation
1.1
Unpacking
Carefully open the shipping carton and check for any noticeable damage.
Every Martin Audio amplifier is completely tested and inspected before leaving the factory and should arrive
in perfect condition. If you find any damage, notify the shipping company immediately. Be sure to save the
carton and all packing materials for the carrier's inspection.

Mounting
The MA12K & 12K DSP amplifiers will mount in a standard 19" rack. Four front panel mounting holes are
provided. Rear support mounting holes are also provided. These should always we used to support the
weight of the amplifier at the rear in a 19” rack.
Your MA12K & 12K DSP amplifiers uses a forced-air cooling system to maintain a low, even operating
temperature. Drawn by an internal fan, air enters through the slots in the front panel and courses over and
through components. The MA12K & 12K DSP series amplifiers feature an "intelligent" variable-speed DC fan
which is controlled by heat sink temperature sensing circuits: the fan speed will increase only when the
temperature of either heat sink requires it, which keeps fan noise to a minimum and helps cut dust
accumulation inside. Under extreme thermal load, the fan will force a very large volume of air through the
heat sinks.
