PRODIGI 2800

Firstly, Business tool to predominate PA market

PRODIGI series guides you to the new world of OTL (Output Transformer Less) class-D amplifier.

Are you still unsure about using an amplifier with no output transformer?

Our company, Karak Electronics Co., Ltd, specializes in Public Address filed since 1977 year hereby open the chance for you to step up to the advanced, convenient and economical PA business with PRODIGI series at best price.

Next, Users’ convenience : 1U type and light weight less than 5kgs

Our own full digital technology supports the concept to be free from output transformer and makes it come true to produce the powerful amplifier of slim design and light weight.

OTL amplifier makes you free from the workload using heavier and bigger size amplifiers in limited space when you construct PA system.

It also guarantees state of the art sound based on own class-D technology removing noise factors due to output transformer.

Next, Cost Saving : SMPS plus PFC

It reduces overall cost and allows for straight 70/100V operation.

At a glance over the power consumption comparison with ordinary PA amplifiers, you can see the extremely low power consumption of PRODIGI series.

At the power module, PRODIGI series was equipped with a variety of protections utilizing advanced SMPS (Switching Mode Power Supply) technology.

It means significant improvement in energy efficiency compared with the linear power of analog PA amplifiers.

In addition, we adopted PFC (Power Factor Correction) to satisfy the European standard aiming for environment friendly product and the well established PWM (Pulse Width Modulation) technology to minimizes the output energy changed into heat consumption to save money.

Next, Intelligent Protection (100% isolation)

PRODIGI series provide automatic switching to DC24V in case of power failure and built in protection circuit to prevent short circuit, over-current and over-heat.

Despite the benefits of the class-D amplifier, some people may reluctant to try an class-D amplifier because they may worry if the amplifier shorts out, it might possibly damage its speakers.

Even some people may rely on the function of the output transformer to prevent damage of amplifier in case of any failure : short circuit, over-current and over-heat.

As we have understanding on such accident cases and users’ need for protection, PRODIGI series have been designed to perform such amplifier protection function even without output transformer under any circumstances, and the safety has been verified through field tests.

Furthermore, we made a simple video clip that was already uploaded on YouTube site.

Next, Optimized for PA

The only reason the ordinary PA amplifier needs its output transformer is to step up the amplifier’s low voltage output to 70V/100V. PRODIGI series have been built with 70V/100V load in mind on the basis of our business experience and technical know-how in PA filed over 30 years.

Finally, Competitive price

As you know well, the most negative fact of class-D amplifier is it’s high cost but we are trying to reduce the cost continuously with keeping quality.

Feel free to contact us to achieve the price quotation within your target level, which may support you to explore advanced digital market replacing existing analog PA amplifiers.

We are ready to support your business with best sample price and volume discount program.
