Q: tôi muốn hỏi sơ đồ kết nối đầu vào bo công suất ?

maurits On the bottom of the circuit board you can see two soldering connecting points next to each other marked GND (ground) and 24V respectively. Use a 24V DC power supply and connect its positive output to the 24V connection point, and its negative output to the GND connection on the circuit board.

Q: What is the third pole on the female contact?

gevraagd door Arnror op 2022-09-01 15:35:28

maurits The innermost negative terminal on the socket is connected to the negative pole of your equipment's internal power source (usually batteries), and the outermost ("third") negative terminal completes the negative line to your equipment. When a plug from an outside power source is inserted into the plug, it disconnects the batteries, and supplies its own power to your equipment. (Of course the plug's positive terminal (the centre one) must be connected to the your equipment's positive line.)

Q: Can i connect 2 subwoofers in one slot from the crossover??

gevraagd door BG524861413 op 2021-06-21 10:10:16

maurits As long as their combined impedance is not lower than 4 ohms, you should be able to connect any number of subwoofers. The formula for calculating combined impedance or resistance is easily found on the web.

Q: Why there is no UK plug?

gevraagd door Fai00 op 2022-02-01 11:20:23

maurits It seems all the ones with UK plugs have been sold out. Ust get yourself a US to UK adaptor plug. Voltage will be OK since the AC adaptor is rated for 100 to 240 volts.
