PROFESSIONAL POWER AMPLIFIERS

Connecting Power / Circuit Size Requirements.

MP Series amplifier power requirements are rated at:

a) "idle"

b) 1/8th power ("typical" music conditions)

c) 1/3rd power ("continuous" music conditions)

d.) maximum rated power ( under limited).

The maximum power current draw rating is limited only by the rear circuit breaker(3U MODEL) or the fuse

type (2U MODEL) . Consult the specifications section for figures on the current that each amplifier will

demand. Make sure the mains voltage is correct and is the same as that printed on the rear of the amplifier.

Damage caused by connecting the amplifier to improper AC voltage is not covered by any warranty.

Unless otherwise specified when ordered, DynaTech amplifiers shipped to customers are configured

as follows:

North America

Europe

Asia

Australasia

South America

Japan

NOTE: Always turn off and disconnect the amplifier from mains voltage before making audio connections.

Also, as an extra precaution, have the attenuators turned down during power-up.

Cooling System and Requirements.

MP Series amplifiers use a twin-tunnel forced-air cooling system to maintain a low, even operating tempera-

ture. Drawn out by dual 45 cubic feet-per-minute (CFM) fans on the rear panel, air flows from the front grill

and through the cooling fins of the channel heat sinks (dissipating power transistor heat), then exhausts thr-

ough the back panel ports. The "intelligent" variable-speed DC fans are controlled by heat sink temperature

sensing circuits. When the amplifier is turned on, the fans briefly "rev up," then slow to an idle; this indicates

that the temperature sensing circuits are operating normally. The fan speed increases only as required by

heat sink temperatures, keeping fan noise to a minimum. Under extreme thermal load, the fans will force a

very large volume of air through the heat sinks. If either heat sink surpasses the maximum allowed temper-

ature, the sensing circuit will shut down the output, no signal output to the load . If the power transformer

overheats, another sensing circuit shut down both channel output until the transformer cools to a safe temp-

erature.

IMPORTANT: To ensure optimum cooling, periodically clean the amplifier fan filters. Also make certain that

there is enough space around the back of the amplifier to allow the cooling air to escape. If the amplifier

s rack-mounted, do not use doors or covers on the front of the rack, the exhaust air must flow out without

resistance. If the amplifiers are to be housed in racks with closed backs, allow at least one (1) standard rack

space of opening in the front of the rack for every four amplifiers.

Connecting Inputs.

Use either the XLR or 1/4-inch input connectors on the rear to supply audio signals to your DynaTech MP

Series amplifier. Both connectors accept balanced and unbalanced audio connections. (The MP Series

amplifiers are configured standard with "Pin 2 hot" on XLR inputs. Please note that some other Audio

amplifiers are configured with "Pin 3 hot"). The unused connector can be used to jumper the audio input

to another amplifier input.

Connecting Outputs.

Speakers are connected using Output Binding Posts or Speakon connectors, For more information, see the

Mode Selection sections.
