Product features：
1. Use of high-quality materials, durable
2. Using high-power digital amplifier chip
3. Small volume design, BTL output
4. Easy to use
5. Wide range of applications
Parameters：
Board size: 50mm*33mm
Operating voltage: DC5V-22V
Output power: 80W (peak power)
Overall height of the board: about 13mm
Need to pay attention to heat dissipation when using high power
Silent control description：
M is the mute control terminal, low-level mute, high level work (control voltage can be from 3v-24v)
Signal input mode can be selected according to the need for the following two:
1: Signal balanced input (differential): signal +, signal -, signal
2: unbalanced input (single-ended): - terminal and GND (ground) short, the signal from the + terminal input.
Note: the unbalanced input must be "-" and GND short-circuit connection, otherwise the sound is not normal, serious may burn the chip.
Using high-power digital amplifier chip, small volume design, BTL output, high-power 80w, single-ended input, can also be balanced (differential) input, the chip plus heat sink work more
stable.
