The amplifier module embedded in the system has been made some optimization based on previous version.
RS-485 and USB port are added into it for computer connection, it will be very convenient for user to
configurate system parameters by software. Built-in stepless cooling fan(Speed will be changed according to
the temperature automatically to make sure system work stably), overload protection, short circuit protection
(avoid the damage of amplifier when abnormal loading occurred) and temperature protection(when the
temperature is over the normal range, DSP will attenuate the output, if temperature is normal ,then amplifier
＇
s
output recover to normal status). give the user the complete guarantee. The peak indication function has been
improved on R8 , the new version has the AD overload indication and DSP overload indication, it will be very
easy for user to control this system. Adopted more advanced IC bring a big progress on Audio performance.
