from high end field. Unique diagram and SMT technology make the amplifiers
have superior sound quality and incredible reliability. 2 ohm stable makes the
amplifiers a large variety of use whatever in installation and DJ use. It is the best
choice for your high end field.
MA series amplifier has full-protect function, including:
. Soft start function to prevent wave-shock at switch power on
. Delay function for preventing shock at switch power on
. DC protection
. Over-electric current protection
. Cut-wave protection
. Over heat protection

Installation guidelines
DO NOT use these amplifiers in damp or high humidity environments.
Do not use outdoors or anywhere where liquids could fall or splash onto the amplifier.
Ensure the amp is adequately ventilated, with free airflow to the front and rear panels.
Keep away from other heat sources. If the amps are mounted in a rack with other amps,
ensure there is adequate cool air flow front and rear. Note that air is drawn in through the
back panel, and exhausted through the front panel.
NEVER cover the amplifiers, as they may overheat.
The power amplifiers are designed to fit standard 19” racks, with a 2U height
and 17 depth. We recommend the use of rear rack supports, especially if the rack is to
be mobile. Use shake proof washers or thread lock adhesive to prevent mounting bolts
becoming loose in transit.
Ensure that the AC power supply is correct for your amplifier. The required AC supply
is stated on the rear panel next to the AC power input.
Ensure that you use the correct type of mains lead for your equipment and country.
This must be free from damage and easily accessible during use.
