BR SERIES
BR series power amplifier
1. The appearance is novel, the craft is exquisite, the quality is reliable.
2, perfect protection circuit. The stability of the whole machine depends on the advanced and complete protection circuit.
The protection circuit of BR series is not only on the DC protection of loudspeakers, but more importantly, it can adapt to the harsh working environment and work easily.
The BR series uses a perfect temperature control protection circuit, which is a perfect solution to the fatal injury caused by overheating. When the temperature reached 90 degrees, will automatically cut off the power amplifier and loudspeaker
When the temperature falls to 88 degrees centigrade, the power amplifier will automatically recover and work normally.
BR series short-circuit protection function, it can ensure the engineers in the wrong operation or other unexpected situations, and protect the machine itself and speakers safely and reliably.
3, limiter
It is a very effective protection circuit to prevent the damage of the loudspeaker. When the clipping overload occurs in a power amplifier, a large amount of harmonic energy will be generated to damage the loudspeaker. For this purpose, a nonlinear comparator is specially set in the BR series amplifier. Once the signal is clipped, the working state of the power amplifier circuit can be immediately adjusted until the clipping is eliminated.
4, excellent audio performance
BR series power amplifier has excellent signal conversion characteristics. It has very small harmonic distortion (THD), intermodulation distortion (SMPTE-IM), and transient intermodulation distortion. The sound quality of pure and natural is deducted to the perfect music.
5, light touch open soft start, anti surge protection.
6, time delay, shut down sound protection against impact. The protection of the loudspeaker is not noisy with a strong shock current.
