The switch control board is designed separately from the power amplifier board, so that different products can be arranged in different positions. The remote control receiver can be connected separately by the connection of 2.54-3P, and the remote control receiver can be taken out at will!

In order not to appear high and low frequency and vocal in the playback interrupt layer, design 2.0 for full-range output, 20-20KHz, high and medium bass have output, to listen to the good 2.0 please connect full-range speakers or high and low frequency speakers, subwoofer output only 120Hz The low frequency of the center, if the 2.0 speaker is too small or the speaker sensitivity is too high, it may cause the low and medium frequency to connect to the fault!
