Hot Sale TS-50WGF-A 9V ~ 25V 50W + 50W Double-Track 100W Mono Digital Audio Amplifier Board

Features:
The board uses high power amplifier chip. 
Power input connections: Can match socket or switching power supply DC input audio Socket.
Audio input connections: Standard 3.5mm audio input socket, or from 3pin input audio socket.
Supports high voltage 25V power supply, support parallel bridge 100W Mono Output, Supports with low impedance of the speaker, can be used with most speakers on the market. 
Especially suitable for your demanding.
Output power: 
Tip: To the audio input enough, the power supply voltage / current under the condition of enough, will have enough power output. Power supply voltage is higher, and the relative power will be bigger, different speakers have different output power and output impedance. In enough voltage current situation, the speakers’ number is larger, the smaller relativity sound power, please note.
Double-track Output Power:
12V / 10 + 10W (8ohm) / 15 + 12W(4ohm) 
15V / 13 + 13W (8ohm) / 25 + 22W(4ohm) 
19V / 22 + 13W (8ohm) / >39 + 39W(4ohm)
22 ~ 24V / >32 + 32W (8ohm) / > 50 + 50W(4ohm)
Parallel Bridge Mono Output Power:
12V / 18W (4ohm) / >22W (3ohm) / >30W (2ohm)                                                     15V / 27W (4ohm) / >35W (3ohm) / >48W (2ohm)
19V / 45W(4ohm) / >55W (3ohm) / >75W (2ohm)
24V / >70W (4ohm) / >95W (2 ~ 3 ohm)
