Intro
INTRODUCTION
Nissindo is proud to introduce a high power amplifier MA
Series to the North America market. They are designed by
the Nissindo engineering team with the advanced audio
technology. One of the distinguished features of this new
amplifier series is that they produce crystal clear vocal sound
and music for singing as compared to other brands in the
market.
If you want a high-performing, precise clarity, low
temperature, reliable, and portable power amplifier, you may
look into our MA Series. Coming in three models, the
MA-1200 G2 (1,000 watts), MA-1330 (2,000 watts) and
MA-2000 (3,200 watts), the MA Series power amplifiers
give you high power (which is as high as 3,200 watts),
compact size 2-space, and efficiency for your application.
They feature Nissindo’s latest Auto Temperature and Loads
Compensated Impedance and Supply Control Technology™
circuitry for clean, undistorted sound with the ultimate circuit
protection needed by amps which often get pushed to the
limit.
The Nissindo engineering team has brought the power and
portability of high power amplifier into the consumer market.
The compact 2U design of the KTV can easily be mounted
onto the versatility of the compact DJ rack system or any
Karaoke Rental Gear; allowing many restaurants and bars
venue to have sound quality on rack or on the go for
maximum power and portability.
To expand into high power (as high as 3,200 watts), the
MA series would go with either a pre-amplifier or a mixer. A
normal mixing amplifier can produce the power from 200
watts to 800 watts only.
The Nissindo MA Series has elevates the audience’s
experience by combining the power of professional precision
crossovers and acoustic correction for high definition clarity
and performance. While the MA Series can thrust a huge
amount of bass that the audiences can literally feels the
pressures, it does not create the "muddy" overall sound like
other systems, even for those directly in front of the speaker.
Instead, it delivers the vocal and music in a very precise,
focused, high-definition quality sound to its very limits,
providing clearer, and more accurate sound to the entire
audience; even when used in highly reverberant huge area
like churches and banquet halls.
Features

SPECIAL FEATURE DESCRIPTIONS
AC-POWER SWITCH
Before applying power, check all connections and turn
down the gain controls. The "soft start" sequence starts with
the POWER indicator LED at half brightness. A couple
seconds later the fan starts and the amplifier cycles through
one second of protective muting, indicated by the CLIP LEDs
glowing bright red. The POWER indicator then changes to
full brightness and the amplifier is ready.
The power cord has a big beefy cord built in. Plug the
power cord into a 3-prong outlet that is capable of
delivering 110~120V at 15 amps.

LED INDICATORS
The LED indicators can be used to monitor system operation
and identify common problems.
BRIDGE: Each channel pair has a YELLOW LED for BRIDGE
Mode. These show how the rear panel switches are set. In
Stereo mode, both LEDs should be OFF.
PEAK: RED, under each BRIDGE LED. Each channel pair has
a RED LED for PEAK Mode.
Normal indication:
The PEAK indicator illuminates whenever the amplifier is
driven beyond full power. The resulting distortion corresponds
to the brightness of the LED. Distortion that causes only brief
flashing may not be audible.
• During muting, the LED fully illuminates. This occurs during
normal "On-Off" muting.
Abnormal indication:
• Bright RED illumination while the amp is being used
indicates either thermal muting or a shorted output.
• If the amplifier overheats, the fan will run at full speed,
and operation should resume within one minute. Allow the
fan to run, and make sure the amplifier ventilation is
adequate.
• A shorted or overloaded output circuit will cause excessive
PEAK flashing and possible overheating.
If distortion is audible without a PEAK indication, the problem
is either before or after the amplifier. Check for damaged
speakers or overloaded signal source. The amplifier Gain
control should be in the upper half of its range to prevent
input overload.
SIGNAL: GREEN, under each PEAK LED. Each channel pair
has a GREEN LED for SIGNAL Mode.
Normal indication:
The SIGNAL indicator illuminates when the input SIGNAL
exceeds -35 dB, the -20dB indicator illuminates when the
signal exceeds -20dB, and the -10dB indicator illuminates
when the signal exceeds -10dB.
If no indication:
check Gain settings and increase gain if necessary. Check
input connections and audio source for signal. If the SINGAL
LED illuminates with little or no signal indication, check the
output wiring for shorts.
Abnormal indication:
If the SIGNAL, -20dB, or -10dB LED illuminates with no signal
input, there may be system oscillations or some other
malfunction. Disconnect the load and fully reduce the gain. If
the LED remains on, the amp may need servicing.
BRIDGE MONO MODE
What It Is
BRIDGE mono mode combines the power of both amp
channels into one speaker, resulting in twice the voltage
swing, four times the peak power, and approximately three
times the sustained power of a single channel. This mode uses
Channel 1's input, gain control, input filter, and PEAK limiter;
Channel 2's have no effect.
The BRIDGE LED on the front panel indicates when the amp is
in BRIDGE mono mode.
When To Use It (or Not)
Use BRIDGE mono to deliver the power of both channels to a
single 8 or 4 ohms load. Set switch position 7 to "BRIDGE
MONO ON." Use Channel 1's inputs, and connect the
speaker as shown.
Bridge-mono Precautions:
This mode puts a high demand on the amplifier and speaker,
Excessive clipping may cause protective muting or speaker
damage. Be sure the speaker has a sufficient power rating.
Output voltages greater than 100 volts rms are available
between the amplifier's BRIDGE terminals. NEC CLASS 3
wiring methods, as specified in accordance with national and
local codes, must be used to connect the speaker.

PARALLEL INPUT MODE
What It Is
The "Parallel Input" switches let you operate the amplifier in
parallel mode, delivering the same SIGNAL to both channels
without using a Y-cable. Each channel drivers its own speaker
load, with independent gain, filtering, and clip limiting.
Set switch positions 4, 5, and 6 "ON" to couple the inputs
together. Turn the switches off for stereo, bridge, or other
2-channel modes.
With the inputs in parallel, you can use the other set of input
connectors to carry the SIGNAL to other amps. This is often
called a "daisy-chain."
When To Use It
Parallel the inputs when driving two speakers with one input
SIGNAL (parallel mode) while keeping separate control of
both channels' gain, filtering, and limiting. Use them in
BRIDGE mono mode to patch the SIGNAL to additional
amplifiers through the extra input jacks.
If you are using a balanced SIGNAL, use only
balanced patch cables; even one unbalanced cable will
unbalance the entire SIGNAL chain, possibly causing hum.
Turn off the "parallel Inputs" switches when feeding the amp
two separate SIGNALs.
WHAT ARE THE DIFFERENCES AMONG STEREO,
PARALLEL INPUT, AND BRIDGE MONO MODES?
Stereo Mode
This is the "normal" way of using the amplifier, in which each
channel is fully independent. Separate SIGNALs connect at
the inputs, the gain knobs control their respective channels,
and separate speakers connect to each output.
Examples:
• Two-channel (stereo) playback.
• Two independent mono SIGNALs, such as main and
monitor mixes.
• Bridge operation, with the low frequencies in Channel 1
and the highs in Channel 2.
Parallel Input Mode
This mode is just like Stereo mode, except that the inputs for
Channel 1 and Channel 2 are internally connected together.
A SIGNAL into any input jack will therefore drive both
channels directly. Each channel’s gain control still functions as
usual, and each channel feeds its own speaker load.
You can patch the input SIGNAL on to additional amplifiers
by using any of the remaining input jacks.
Example:
• One mono SIGNAL driving both channels, with
independent gain control each speaker system.
Bridge Mono Mode
This mode combines the full power capabilities of both
channels into a single speaker system. The amplifier internally
re-configures so that both channels operate as a unit. This
delivers double the output voltage, resulting in four times the
peak power and three times the sustained power into a single
8 or 4 ohms speaker load.
Example:
• Driving a single 8-ohm speaker with the combined 4-ohm
power of both channels.
• Driving a single 4-ohm speaker with the combined 2-ohm
power of both channels.
Precautions:
• BRIDGE Mono mode makes it possible to drive thousands
of watts into a single speaker. AC current consumption will
usually be higher. Avoid excessive SIGNAL level, and make
sure the wiring and speaker can handle the power.
• If the load is less than 4 ohms, or prolonged overloads
occur, the amplifier will probably mute for several seconds
during peaks.
• Do not use 2 ohms loads.
FAN COOLING
The fan speed varies automatically to maintain safe internal
temperatures. Keep the front and rear cents clear to allow full
air flow. Hot air exhausts out the front of the amp so it does
not heat the interior of the rack. Make sure that plenty of cool
air can enter the rack, especially if there are other units which
exhaust hot air into it.

EXAMPLE OF SPEAKON CONNECTOR
There are two groups on the speakon connectors: Group 1
(+1, –1) and Group 2 (+2, –2) as indicated in the diagram. In
order to use it, your speaker must have multi-functions (i.e.
enable two sources of signal for input). If your speaker does
not have multi-functions, it would not work with the Group 2
for connection. Please refer to the following diagram for
connection.
Speakon Outputs
The upper Speakon jack has both Channel 1 and
Channel 2 outputs, so it is especially useful for parallel,
bi-amp, or BRIDGE mono operation. The other Speakon
carries only Channel 2's output. See the illustrations at
above.

effect signals are
controlled by the
pre-amp/mixer only.
The power amplifier

CLIP LIMITERS SETUP:
As the below drawing, when switch is OFF, the limit is off, the
limit circuit is out of work, if input signal is too strong, output
can cause clip distortion and also raise overload on
loudspeaker.
when the switch is ON, the limit is on, if the input signal is
too strong, the limit circuit can control the gain and reduce
the distortion, also control the average output power, but it
does not affect peak power, protect the loudspeaker and
assure the dynamic of music. Note: Please set to "ON"
position when using.

MODE SETUP:
Stereo Connecting Mode:
As below drawing, put the switch of mode at stereo. Under
the stereo mode, the signal on channel-1 and channel-2 is
independent, the signal to channel-1 is just for channel-1, the
signal to channel-2 is only for Channel-2.
Mono Paralleled Mode:
As below drawing, put the switch of mode at PARALLEL.
Under the mono parallel mode, the effect of input signal from
channel-1 and channel-2 are same. The signal on input
channel-1 can be provided to output 1, also to output 2. The
signal on input channel-2 is not only provide to output 1, also
to output 2. Do not input the signal from channel-1 and 2 at
the same time.
The mono parallel mode just means the parallel of input
signal. Never parallel the output terminals.
Bridge Mode:
As below drawing, put the switch of mode at BRIDGE. Under
the bridged mono, signal just can be input from channel-1, no
voice if input from channel-2, the anode of output 1 is the
anode of bridged output, the anode of output 2 is the
cathode of bridged output.
When LF FILTER is at 50Hz,
it equals discrete a 50Hz high
pass filter on input, the signal
lower than 50Hz will be
accordingly attenuated, then can
reduce the non-effective swing
and lower the distortion.
