First, the power :
1 , power transformers , power transformer windings must first be connected to the board through the rectifier bridge, auxiliary power 5V-12V transformer can be connected directly to the board.
2 , if the switching power supply can be connected directly to the board , you need to have two sets of main and auxiliary power outputs are ± symmetrical power supply voltage Vice ± 7V - ± 16V.
Second, the signal line connection:
1, the dual-channel mode: This mode is 2-channel input , 2 -channel output , a board can form a two-channel amplifier .
At this point, the band switch should be appropriated to the right (ST position ) , left and right channel audio signals directly into two RCA holes output ( power supply terminal side ) OUT1 OUT2 , respectively, then the left and right channel speaker .
2, the bridge mode (mono ) : This mode is the mono input , mono output .
At this point, the band switch should be to the left (MON position ) , the audio signal directly into a hole above the RCA (IN1), 2 outputs ( supply -side side ) OUT1 OUT2 respectively connected to the positive and negative terminals of two speakers .
