PRODIGI250D
Professional Digital Amplifier
▪ High-efficiency digital Class-D power amplifier (>85%)
▪ Increased space utilization by enabling high output in
small size
▪ Power supply SMPS application
▪ DC backup in case of power failure or emergency
▪ Replace output transformer with electronic circuit
▪ A short circuit protection circuit is applied to protect
the amplifier in case of a short circuit
▪ Remotely control power through external contact point
▪ High-pass filter improves sound clarity
▪ Output impedance selectable (70V/100V)
Smaller and lighter, zero installation burden
Karak Electronics' power amplifier PRODIGI is a compact, lightweight Class-D power amplifier that uses SMPS in the power supply and is designed without a transformer at the output stage.
PRODIGI can dramatically reduce the volume of the power amplifier, which takes the largest amount when configuring a broadcasting system. When compared with the same capacity, if PRODIGI is used, the number of rack cabinets can be reduced and the burden on the installation space can be reduced.
In addition, it is easy to install at 5Kg compared to the existing power amplifier, which has been burdened during installation with its weight approaching 20Kg.
Speaker line short, don't worry
The power amplifier PRODIGI of Garak Electronics Co., Ltd. has a built-in line short protection circuit to prevent damage to the output circuit in case of a speaker line short occurring in the field.
In an emergency situation where emergency evacuation broadcasting is necessary, the broadcasting is interrupted due to a short circuit, which leads to an unfortunate situation in which personal injury increases. Therefore, there is a line short protection device, but if the power amplifier is damaged due to momentary overload when a line short occurs, it is impossible to maintain broadcasting. PRODIGI has the best stability through more than 40 years of field experience and more than 10 years of field testing.
