What is btl medical beauty equipment?

1: Connection is difficult. One is that the signal port of the power amplifier is not enough, and the other is that the impedance may not match, so it is only used for testing. Emergency use is as follows.

2. Microphone receiver-voltage limiter-equalizer-power amplifier-speaker.

3. Emergency connection, mono signal to solve the problem of dual speaker output. Answer: If the small signal of the power amplifier can jump, jump from the small signal output of channel A to the signal input of channel B. B: The power amplifier is set to BTL output, and the two speakers are connected in series.
