- INPUT+, INPUT- for Input Signal
- OUT+ for Speakers' +; GND for Speakers' Earth Wire
Note:
- For non-professional uses, it is unnecessary to adjust the quiescent current of our finished board which has passed related tests.
- Due to the negative temperature system, the GS voltage of FET will be reduced by around 150mV after having been worked for 10 minutes. It is recommended to use high power amplifier tube with 420mV for its first and third pins which will rise to 600mV after application for several minutes. For professional adjustment, please start testing of the quiescent current of the board after operating for 10 minutes.
