Attention for connect the circuit F-6088 When BK3231 connect external amplifiers, it must connect differential input amplifier. If not, the module must connect an op-amp to balance two difference levels; otherwise, it will appear the "snapped" impact sound. Statement: A Wireless Bluetooth use environment: the wireless signal is widely influenced by the surrounding environment. Such as the trees and metal can absorb certain wireless signal. Therefore, the transmission distance has been influenced in the application. B The Bluetooth Modules are supporting the existing system, placed in the shell. However, the metal shell can shield the wireless frequency signal. We suggest not to equip-ed it in a metal shell.
