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.

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.
