2. The speaker protection board has a power-on delay and DC protection,instant shutdown feature,all-round protection of your expensive speaker!

3. Mute delay boot,shutdown speed off.

4. Protection board uses three 10A high-power relays, which can be easily connected to various power amplifier boards.

5. Amplifier midpoint potential protection,the midpoint of DC from the control point of more than 0.7V.

6. All finished boards are good debugging,and power test.

7. Dual indicator lights display, one is the power indicator, the other is the switch indicator.

8. Sheet selection 1.6MM thick high-FR-4 board manufacturing tin foil sprayed,10A relay is loose music quality, the resistance rings are gold film resistor copper feet. And with a red power indicator,power relay approximately 3 seconds,indicating that green light,the work indicator.

9. The protection board using a single power supply voltage AC 12V-18V,you can take a group of electric power to the amplifier board.Try to use conditional independence winding or separate power supply.

10. All finished boards are good debugging,and power test.

Note: 2 sets of BTL circuit strings are required. The speaker protection needs independent winding power supply, and cannot share power with other circuits.
