Amplifier power switch  turn on sequence: turn on the card holder, CD machine, LD machine or VCD machine, tuner, equalizer, and finally turn on the power amplifier. Amplifier power switch turn off sequence: first turn off the power amplifier, then turn off other equipment. So there are delayed plug boards invented abroad. The first group of sockets is direct switch sockets. The second group of sockets, when this machine is turned on, can delay 1 s (seconds) to turn on the power supply. The third group of sockets, when this machine is turned on, can delay 2 seconds to turn on the power supply. The fourth group of sockets, when this machine is turned on, can delay 3 seconds before switching on the power supply. Similar to this, the amplifier power switch is also turned off in different periods. This prevents the phenomenon that surge current and reverse peak voltage act simultaneously on all eq...
