Product description
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 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.
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.
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.
