1. The product must be used to supply dual-output toroidal transformer, the output is 3 wires. DC power supply can not be used. Transformer output to 24V200W above, the maximum voltage can not exceed 28V, otherwise it may damage the board.
2 Audio input can be 3 lines or 2 lines, but in the middle of the ground must be connected.
3. The output of the speaker as large as possible, the recommended 8 ohms, also can use 4 ohms.
4. This section is a purely post-class, plus the tone board is better, but after adding tone board, the tone board power and power amplifier board power must to separate . can not be shared, otherwise there will be noise!
