Important Precautions
This symbol is used to alert the oper-
ator to follow important operating
procedures and precautions detailed
in documentation.
This symbol is used to warn opera-
tors that uninsulated "dangerous volt-
ages" are present within the equip-
ment enclosure that may pose a risk
of electric shock.
1.Save the carton and packing material
even if the equipment has arrived in
good condition. Should you ever need
to ship the unit, use only the original
factory packing.
2.Read all documentation before oper-
ating your equipment. Retain all doc-
umentation for future reference.
3.Follow all instructions printed on unit
chassis for proper operation.
4.Do not spill water or other liquids
into or on the unit, or operate the unit
while standing in liquid.
5.Make sure power outlets conform to
the power requirements listed on the
back of the unit.
6.Do not use the unit if the electrical
power cord is frayed or broken. The
power supply cords should be routed so
that they are not likely to be walked on
or pinched by items placed upon or
against them, paying particular atten-
tion to cords and plugs, convenience
receptacles, and the point where they
exit from the appliance.
7.Always operate the unit with the AC
ground wire connected to the electri-
cal system ground. Precautions should
be taken so that the means of ground-
ing of a piece of equipment is not
defeated.
8.Mains voltage must be correct and
the same as that printed on the rear
of the unit. Damage caused by connec-
tion to improper AC voltage is not cov-
ered by any warranty.
9.Have gain controls on amplifiers
turned down during power-up to pre-
vent speaker damage if there are high
signal levels at the inputs.
10.Power down & disconnect units from
mains voltage before making connec-
tions.
11.Do not turn the power switch on the
"ON" position if you do not use it.
12.Do not use the unit near stoves, heat
registers, radiators, or other heat
producing devices.
13.Do not block fan intake or exhaust
ports. Do not operate equipment on a
surface or in an environment which
may impede the normal flow of air
around the unit, such as a bed, rug,
weathersheet, carpet, or completely
enclosed rack. If the unit is used in an
extremely dusty or smoky environ-
ment, the unit should be periodically
"blown free" of foreign matter.
14.Do not remove the cover. Removing
the cover will expose you to potentially
dangerous voltages. There are no user
serviceable parts inside.
15.Connecting amplifier outputs to
oscilloscopes or other test equipment
while the amplifier is in bridged mode
may damage both the amplifier and test
equipment!
16.Do not drive the inputs with a signal
level greater than that required to
drive equipment to full output.
17.Do not connect the inputs / outputs
of amplifiers or consoles to any other
voltage source, such as a battery,
mains source, or power supply, regard-
less of whether the amplifier or console
is turned on or off.
18.Do not run the output of any amplifi-
er channel back into another chan-
nel's input. Do not parallel- or
series-connect an amplifier output
with any other amplifier output.
19.Do not ground any red ("hot") terminal.
Never connect a "hot" (red) output to
ground or to another "hot" (red) output!
20.Non-use periods. The power cord of
equipment should be unplugged from
the outlet when left unused for a long
period of time.
21.Service Information Equipment
should be serviced by qualified service
personnel when:
A.The power supply cord or the plug
has been damaged;
B.Objects have fallen, or liquid has
been spilled into the equipment;
C.The equipment has been exposed

Introduction
Congratulations on your purchase of a new MP Series professional power amplifier, and thank you for your
confidence in DynaTech products.
For your safety, please read the Important Precautions section before installing and operating the amplifier.
The DynaTech MP Series is based on the same advanced circuit topologies that have made DynaTech amplifiers
the choice of touring professionals worldwide. MP Series amplifiers are designed for high operating efficiency
and accurate sonic performance across the full audio bandwidth, even under stressful conditions. Internal com-
ponents are the finest available, and key sub-assemblies are pre-tested before final assembly. Finally, each ampl-
ifier is "burned in" and thoroughly tested (using precision audio test equipment) before shipping. In addition,
all MP Series amplifiers incorporate DynaTech’s exclusive Tour Class protection features to safeguard both inte-
rnal circuitry and connected loudspeakers. This proven combination of advanced design, quality construction,
and comprehensive circuit protection is your guarantee of fail-safe reliability. You can depend on consistent,
stable performance even when your MP Series amplifier is subjected to punishing extremes in the most deman
ding fixed or mobile sound reinforcement applications.
Please inspect the amplifier carefully immediately after unpacking. If you find any damage, notify your
supplier/dealer immediately. Only the shipper may file a damage claim with the carrier for damage incurred
during shipping. Be sure to save the carton and all packing materials for the carrier's inspection. If your
packing materials are in good condition, please save them. If you ever need to ship the unit back to DynaTech
or an authorized service center, you should use only the original factory packing.
Unpacking
Only one MP Series amplifiers are 2-rack-space units: MP-3000 and MP-4000/MP-5000/MP-7000 are 3-
rack-spaces high. All mount in standard 19-inch racks. Four front-panel mounting holes are provided on
each amplifier. Rear mounting ears give additional support, and use of rear supports is highly recommen-
ded in all mobile and touring sound systems. Optional rack-mount handles are available.

16. Mode Selection Switch.
This recessed, three-position switch configures the amplifier for Stereo, Parallel or Bridged Mode oper-
ation. Amplifiers are factory-configured for Stereo Mode. See section on Mode Selection for more information.
17.Circuit Breaker .
MP Series amplifiers have a circuit breaker. The circuit breaker shuts off during normal use, Please
switching off the AC power switch for a minute, Then turn on the AC power switch again ,Push the circuit
breaker to reset the power. If the circuit breaker shuts off immediately ,The amplifier needs servicing.
18-19.Output Connectors (Two versions, market dependent).
MP Series amplifiers are supplied with either Binding Posts or Speakon connectors. Connection to the
binding posts can be made with bare wire, banana plugs, or spade lug terminations. Make connections to both
the terminals of Channel 1 and Channel 2 for Stereo or Parallel Mode, or a single connection across the red
("hot")terminals only of Channels 1 and 2 for Bridged Mono Mode. Using Speakon-type speaker cables, make
connections to the "+1"and "-1" terminals of Channel 1 and Channel 2 connectors for Stereo or Parallel Mode,
To the Bridged mode connector to the "+1"and "+2" terminals of Channel 1. See section on Mode Selection
for more information.
20.AC POWER Cord .
Connet to AC power supply. Be sure that that the supplied volfage in your area matches the amplifiers
required voltage.
Configuring the Low Cut Filter:
Activating Low Cut Filters 〞Dip switches 1 and 4 activate and deactivate the Low Cut Filter. Channel 1 filters
is controlled by dip switch 1 and channel 2 filter is controlled by dip switch 4.
Low Cut Frequency Selector 〞When the Low Cut Filter is activated, dip switches 2 for channel 1 and 3 for
channel 2 will control the frequency roll-off. When dip switches 2 and 3 are in the "ON" the filter will cut off
frequencies at and below 30Hz, when these dip switches are in the "OFF" position the filter will cut off
frequencies at and below 50Hz. Please note: Each channel operates independently of each other allowing each
channel to have different filter settings.

Operation
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 120VAC / 60Hz
Europe 230VAC / 50Hz
Asia 220VAC / 50Hz
Australasia 240VAC / 50Hz
South America 120VAC / 60Hz or 220VAC / 50Hz
Japan 100VAC / 50Hz
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.
Operation
Connecting Power / Circuit Size Requirements.
Cooling System and Requirements.
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 Inputs.
Speakers are connected using Output Binding Posts or Speakon connectors, For more information, see the
Mode Selection sections.
Connecting Outputs.
Connecting amplifier outputs to oscilloscopes or other test equipment while the
amplifier is in bridged mode may damage both the amplifier and test equipment!
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.

Mode Selection
Page 9
The three-position, recessed Mode Select switch (located on the rear panel) configures the amplifier for
either Stereo, Parallel or Bridged Mono Mode. Amplifiers are factory-configured for Stereo Mode.
Stereo Mode.
In Stereo Mode, both channels operate independently, with their input attenuators controlling their
respective levels. Signal at Channel 1's input produces output at Channel 1's output, while signal at
Channel 2's input produces output at Channel 2's output. Recommended minimum nominal load
impedance for stereo operation is 2 ohms per channel. Either the 1/4" (TRS) inputs or the XLR inputs
may be used.
Parallel (Mono)Mode.
When set to Parallel(Mono) Mode, The signal input to Channel 1 and channel 2 will be added together
and be amplified and appear at outputs for both Channels 1 & 2. The output signal is controlled by each
attenuator
NOTE!: Some other amplifiers only use Channel 1 for input, and both output is controlled by Channel
1 attenuator .
Bridged Mono Mode.
Bridged Mono Mode straps both amplifier channels together to make a very powerful, single-channel
monaural amplifier. One channel "pushes" and the other "pulls" equally, doubling the power over that of
either channel alone. Signal is applied to the Channel 1 input only, both output level is controlled by Chan-
nel 1`s attenuator .
NOTE: The channel 2 input connectors (XLR and/or TRS) may be used to "loop thru" the channel 1 signal
when in parallel or bridged mono mode.
Use extreme caution when operating the amplifier in Bridged Mono Mode. Never ground either side of the
speaker cable when the amplifier is in Bridged Mono Mode; both sides are "hot." If an output patch panel
is used, all connections must be isolated from each other and from the panel. The recommended minimum
nominal load impedance in the Bridged Mono Mode is 4 ohms, which is the equivalent to driving both
channels separately at 2 ohms. Driving bridged loads of less than the recommended minimums will activate
the IGM circuitry, resulting in a loss of power, and may also lead to a thermal protect condition.
Subwoofer Mode
This mode sends low frequencies to your speakers without the use of an external cross-over. The subwoofer
operation can be operated in stereo, mono, or bridge mono modes. Change the different operating modes by
flipping the mode switch on the rear of the unit to your desired operating mode. Also, set the subwoofer mode
switch to the subwoofer position. Use the frequency selector to adjust the subwoofer output frequency from
20Hz to 200Hz. The different subwoofer modes are listed as follows:
Bridge Subwoofer - This operation allows you to get the most possible power out of your amplifier for
the sole purpose of running a high powered subwoofer loudspeaker in mono. To avoid amplifier overheating,
never run the amplifier below 4 ohms in this mode. In this mode you may use the frequency adjustment on
the rear of the amp, to control the frequency output level. Frequencies may beadjusted from 20Hz to 200Hz.
Page 12 details a typical Bridge Subwoofer set up.
Stereo Subwoofer - This operation is similar to the Bridge Subwoofer operation but in stereo. This
operation allows you to run several subwoofers down to a minimum of 2 ohms. To avoid amplifier over-
heating, never run the amplifier below 2 ohms in this mode. Set up this mode as you would a standard stereo
set up. Be sure both channels are set to ※SUBWOOF.§ In this mode you may use the frequency adjustment
on the rear of the amp, to control the bass frequency output level. Frequencies may be adjusted from 20Hz
to 200Hz. Page 10 details a typical Stereo Subwoofer set up.
Parallel (Mono) Subwoofer - This operation is similar to the Stereo Subwoofer operation but in mono.
When running subwoofers it is usually recommended to run them in mono mode to achieve a cleaner tighter
low end. This operation allows you to run several subwoofers down to a minimum of 2 ohms. To avoid amplifier
oveheating, never run the amplifier below 2 ohms in this mode. Set up this mode as you would a standard stereo
set up. Be sure both channels are set to ※SUBWOOF§ and the mode switch is set to ※MONO.§ In this mode
you may use the frequency adjustment on the rear of the amp, to control the bass frequency output level.
Frequencies may be adjusted from 20Hz to 200Hz.
One Channel Normal/One Channel Subwoofer (BI-AMP) - You may also use your amp to
bi-amp your system. You may use one side of the amp to power a subwoofer and the other side to power a
full range speaker.

The MP series comes with a built-in limiter. When the input signal overloads, the “CLIP LED’s” indicate
a signal overload, at this time, the master volume should be lowered to reduce distortion. If the input gain level
is not reduced the built-in limiter will activate. During signal overload, the limiter will reduce the input audio
signal enough to minimize the amount of clipping. A limiter takes the gain of an overloading signal and reduces
it, the reduction in gain reduces distortion that can cause damage to your speakers and amplifier. During
normal operation below clipping, and momentary clips on peaks, the limiter does not affect the audio signal
and is inaudible. It will allow brief clipping of peaks and will only activate when continuous, hard clipping
occurs. During excessive clipping the limiter will reduce the audio signal enough to minimize the amount of
clipping. When the input signal decreases enough that clipping ends, the limiter will deactivate and cease its
gain reduction. The limiter has a fixed threshold and can not be adjusted.
Limiter
8-Ohm Loads: The amplifier can operate at practically any power level without risk of overheating. However,
if it is pushed hard enough to continually light the “CLIP” indicator, the amplifier’s average output power
can reach 150 watts.
4-Ohm Loads: If the “CLIP” indicator flashes occasionally, the amplifier is approaching its maximum
long-term power capacity. If it is lit about half the time, the amplifier channel will probably go into thermal
protection within a few minutes.
2-Ohm Loads: Except for an occasional flash, keep the “CLIP” indicator dark to avoid overheating the
amplifier channel. Clipping should be kept to a reasonable minimum. An amplifier’ s peak current draw at
full output power into 2 ohms is several times what the “normal” draw is, but its various protection
circuits will prevent this condition lasting more than a minute or two.
Safe Power Levels at Different Output Loads
The MP series amplifiers all come with built-in Output Short Circuit Protects. The Output Short
Circuit Protection protects the output devices of the amplifier from short circuits and stressful loads. If your
speaker lines short, the amplifier automatically detects this problem and discontinues operation for that
channel. If one side of your amplifier becomes shorted and goes into protect mode, the other side will continue
to operate normally. During short circuit protection, the “Clip” LED will light simultaneously indicating
amplifier fault. The channel output during the “Short Circuit Protection” will be interrupted (i.e. no sound
output) Short Circuit Protection can usually be traced back to the signal output line (i.e. speaker line). Check
the line from the output terminal of the amplifier to the speaker. If this line good, check the internal speaker
connections and components. A short circuit will usually be traced to a bad cable or a bad speaker component
and is rarely traced to the amplifier itself.
Short Circuit Protection
Thermal Protection
The input circuits are isolated by 10k resistors. An ultrasonic network uncouples RF from the output and
helps keep the amplifier stable with reactive loads.
Input/Output Protection
Dual variable speed fans on the MP series amplifier provide adequate cooling. During low level output the
fans run at normal speeds. During high output and as heat raises, (exceeding 50° C), the fans will run at
higher speeds to aid the cooling process. If the heatsink temperature exceeds 91° C, the amplifier will mute
until the amplifier cools down. When the amplifier cools below 90º C, the amplifier will return to normal
operations. Be sure not to operate your amplifier below the minimum load ratings to reduce the risk of
overheating problems.
The AC main voltage is printed on the back where the AC power input . Connecting to the wrong voltage
is dangerous and may damage the amplifier. Always be sure the source voltage for your areas matches the
required voltage for your amplifier.
