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?ˉ number is larger￡? the smaller relativity sound power￡? please note.
