PROFESSIONAL POWER AMPLIFIER
Before attempting to connect, operate or adjust this
product, please read these instructions completely.
This series CLASS D power amplifier each channel
can provide 300W power output.
In applications that require high power and long-
term reliability, no other amplifier can match its
performance. This series of power amplifiers can
greatly reduce the heat output and equipment weight
without sacrificing output power, and can be used in
a large number of sound amplification applications,
such as opera house, movie theater, church and
theme park.
The power amplifier using CLASS D technology has
high efficiency, which can reduce heat dissipation
and provide higher efficiency for the sound box. The
typical operating efficiency of the output stage is
95%, and only 5% of the input energy is consumed.
This makes it possible to build smaller, lighter and
less power-consuming power amplifiers.
Traditional amplifier can achieve the peak efficiency
only when output in the maximum rated power, and
the power of CLASS D amplifier has little relation with
the output level. The average power density of
music is 40% of its peak. It means that under the
same sound pressure level, other power amplifiers
(non-class D) can be 10 times as hot as this series.
This series of power amplifier can bring clear high
frequency and compact, pure low frequency, is the
most accurate reproduction of audio signal. In the
application, ultra-low THD, optimized frequency
response, high efficiency bandwidth and damp
modulus can be ensured.
