Operating
Instructions
:
The power supply can be accessed from DC socket, or Terminal block socket
Audio from 3.5mm socket 1 or 3P socket 2 input interface, such as: computer, MP3 player, etc.
Bass volume potentiometer, can independently reduce the sound output volume
Left and right channel volume potentiometer, which can adjust the left and right channel output volume
Treble adjustment potentiometer, adjustable left and right channel treble gain output
Switch / total volume potentiometer with switch to turn off the power amplifier / also can also reduce the sound and left and right channel output volume
"Lin"--
sound source left channel input
;     "G"--
Sound source public ground
;  "Rin"--
sound source right channel input
Audio can also be entered from "Lin G Rin" sockets, such as: computers, MP3 players, decoders, etc.
Speaker output "+" or "-" are independent, not common ground output, can not be connected to each other,
nd can not be connected to Ground
,
If the connection will appear sound is not normal.
Speakers output "+" or "-" wiring and speakers on the "+" or "-" corresponding connection, if any wrong will affect the hearing effect
