The mono bridge BLT is the same as above, adjusted according to the actual situation of the customer's speaker.
If high voltage is connected, double 40V-70V needs to pay attention to capacitor withstand voltage: rectification x1.4 = actual working load voltage. Taking the transformer made in China as an example, the dual 70V connected power amplifier x1.4, the actual working voltage will fluctuate around 98-102V. In order to ensure the maximum output and work, please replace the high voltage capacitor. It is recommended to withstand voltage above 100V. To ensure maximum power output and safe operation.

Package includes:

1 x High-power Amplifier Board


Voltage Regulator
