Important Note:
This module is high precision, high integration of CMOS components, in the production, storage, transportation, installation of various process loop knot, please do the electrostatic protection measures, to prevent electrostatic damage to the device!
The signal amplitude of pre-amplifier output should not be too large, it will make the output distortion grievous , influence the sound!
Pls adopts the cross-sectional area greater than 1 square millimeter copper wire as the power line, switch line and a horn line!
AC impedance of the whole speakers may be low as shunted transmission the loudspeaker, even serial transmission capacitive separated directly. Therefore recommended method of wiring and impedance of reasonable selection of the horn in the use value, which can reduce the power amplifier chip music broadcast signal for large dynamic time overcurrent protection!
All the connection line of interfaces, please ensure that the polarity and the module can be inserted into a consistent, otherwise it will burn the module or the front stage components!
