QYC KE1000S Touch Screen and DSP cheap power amplifier sound master, stereo amplifier kit

KE Series intelligent Power Amplifier (without DSP and touch screen)

1. Power Supply
The intelligent power supply of the power amplifier is quasi resonant full bridge topology, the high-frequency transformer
magnetic core using cutting-edge technology of nanomaterials. It has the advantage of high power efficiency, big power, and use
high power tube as the full bridge switch tube, the power of the internal resistance is low. It can provide high current moment to
load. Match the mega bass have enough energy to control paper cone. The presentation of good strength.

2. Amplifying Circuit
KE series intelligent amplifier can work long hours and under pressure with a loud voice power not smaller and it also won't
appear overheating protection. Power amplifier inside there is a real time automatic detection of load impedance circuit. So when
the load impedance is lower than the product of the preset value, detection circuit will call this information is sent to a gain
of self-locking circuit. Circuit will make some corresponding adjustment, in does not affect the products under the premise of
stable work, the output power will adjust according to the size of the load accordingly, so as to ensure the stability of the
product, and doesn't affect the use of the load.
KE series intelligent power amplifier is not easy to overheating protection; the efficiency of the whole machine can reach 89 in 8
Ω conditions. So in normal use is not easy to appear the phenomenon of overheating protection. If due to environment or other
reasons lead to rapid temperature rise of the power amplifier, at a certain temperature, the power amplifier within the sensor
will automatically by the MCU to turn up the volume fell by 1 dB, at this time if the temperature continues to rise, the volume is
automatically drop 1 dB, stop rising and start falling, if the temperature when dropped to a certain temperature, the volume is
automatically increased, so far has been added to the initial value. And it has the very good music quality as class AB amplifier,
and the efficiency of class D power amplifier.

3. Complete Appliance
The intelligent signal amplification and signal processing of the power amplifier and power supply are interrelated. In power
amplifier is started, the total control circuit can automatically detect the relevant circuit state, confirmed after each part of
the circuit there is no problem to start work. In the process of work, each part of the circuit with MCU can own working state
real time detection, and the data sent to the rest of the associated circuits. Other parts at the same time bring the MCU also in
the working state of the field testing itself, and to send the information to the rest of the associated circuit, for mutual
exchange. In the process of information exchange, if data change in one part of the circuit, then the other circuit will
automatically make the corresponding adjustment, make the product stability and reliability to improve on an unprecedented scale.
