Warnings:

In order to protect amplifier board and extend its service lifetime, please read the following warnings carefully since warranties will be voided if you do not observe the following warnings:

Warning 1:

Quality-related issues caused by potentiometers installed by buyers.

Warning 2:

In order to achieve a better sound quality, please use stable power supply since a bad or unstable power supply may worsen the sound quality or even cripple the amplifier board.

Warning 3:

DO NOT equip a pre-amplifier to the audio input since the amplifier itself has powerful amplification ability and a high signal input will burn out the amplifier chip.

Warning 4:

DO NOT use speakers that are rated at less than 3.2 ohm and do not have more than 2 speakers used in parallel.

Warning 5:

Make sure heat is removed appropriately when amplifier is in use and DO NOT put your amplifier board in a narrow or confined space.

Note:

In order to protect amplifier and speaker, please turn the volume output to the minimum when hooking up the amplifier and you may readjust the volume when you are sure that the amplifier is functioning properly; In case gain is to be selected, please select the minimum first and you may adjust accordingly when the amplifier starts working properly.
