TPA3118 Amplifier Board 2.1 Channel Digital Audio Subwoofer Power Amp Board 2x30W+60W
Specification:
Power supply: DC 15-25V
Current: 4A or more
Output power: 30Wx2+ 60W
Output channel: 2.1 channel
Frequency response range: 20-18.5 kHz
Harmonic distortion: THD-1%
Features:
1. TPA3118 high power amplifier board, 2*30W 8 ohm + 60W 4 ohm output. This board adopts the official standard circuit to achieve enough power and low heat, 32db gain test.
2. When the volume is not turned on, the volume is turned on at maximum and low noise is not heard. The test power supply is a 3C and UL certified power supply. As long as the power supply does not interfere with the power amplifier card itself, there is no interference as long as you connect the audio cable.
3. This circuit design uses tpa311x chip test application circuit instead of the official standard circuit, so please do not make any changes to the component circuit on the power amplifier board, in order to avoid unnecessary loss caused by overheating of the chip.
Package List:
1 x Amplifier Board
Note:
-The power supply requirement is 15-25V 4A; the board can work normally under 2*30w 8 ohm + 60w 4 ohm power.
-If only the power supply below 3A is used, the ideal power is 2*25W 8 ohm + 50W 8 ohm.
