Wiring method:
Power connection: AUD2000 requires two sets of voltage input, one set is the main power supply, one set of auxiliary power supply, the main power input is ± DC voltage, the maximum DC ± 80v, the recommended voltage is less than ± 75V, single DC voltage is not suitable, AC For voltage, an external rectifier bridge or rectifier power board is required. Auxiliary power input 6-12v, can be AC single voltage or AC dual voltage, with rectifier filter on the board, if the AC dual power supply, it can be directly connected according to the line sequence, if the AC single voltage, you need to connect 1, 3 wire Together, the two wires with the middle ground wire are directly connected to the AC single power supply. If the DC voltage requires ± voltage, it needs to be distinguished between positive and negative. There is a mark on the board. Do not connect it wrong. The DC single voltage is not suitable.
Signal input connection: the signal can be input to the left and right channel stereo audio signals, marked on the board, L represents left, R represents right, IN represents input, and the middle is the ground wire, connect the two channels to the ground. At the same time, switch Switch to ST position. You can also bridge the mono input. When bridging the mono input, connect the signal input to LIN and ground, leave RIN empty, and change the switch to the MO position.
Signal output connection: when the two-channel stereo output, the two speakers are respectively connected to R-OUT GND and L-OUT GND, when the bridge is connected to the mono output, the speakers are connected to both ends of R-OUT and L-OUT. If you do not understand, please send us a message!
