1. We recommend sufficient power supply, electric current the bigger the better. Suitable speaker&box is equally important, should not be forgotten. 2. Please attention phase of each channel, otherwise potentially reducing efficiency. 3. It is a traditional amplifier, it will heat at work, you can install a fan to cool down. 4. DC out terminal is from the master power, have to be careful to use. 5. How do you judge the sourse of hiss(noise): short circuit the signal input, then monitor the speaker output, if it have no noise, the amplifier is normal; in other word, if the board is connected to PC or mobilephone have some noise, then the noise were from the PC or mobilephone.
