Tiny Subwoofer Amplifier Circuit With UA741
Saturday, April 13, 2013 | Labels: amplifier, circuit, subwoofer, tiny, ua741, with | |Sub-woofer circuit for you take it to use together with your sound device or instruments as the tool is small and few digital section. We offers accomplished PCB and part layout.
Mini Subwoofer Top PCB
We use the IC twin operational amplifiers TL072 on this circuit.
This subwoofer project is a subwoofer or a speaker to pressure low frequencies, rank of 20 Hz to a hundred and fifty Hz electronic circuit diagram below shows in details of a circuit and sections of the primary amplifier UA741 for 22 watt in 4 ohm of car subwoofer forcer and that you would be able to activate VR50K for adjusted regularly of mini subwoofer .
The instrument is designed for an existing stereo amplifier, recurrently requires including another blow to the track of riding a subwoofer.
