Dual NE5532 Preamplifier Board AC5-16V DC6-24V Single Power Supply Amplifier Module Microphone Preamps Audio Operational Amplifier Board

Dual NE5532 Preamplifier Board AC5-16V DC6-24V Single Power Supply Amplifier Module Microphone Preamps Audio Operational Amplifier Board

• Working voltage: AC5-16V or DC6-24V
• The pre-amplifier is designed with two Operational Amplifier, and one Operational Amplifier is used for one channel, and the effect is much better than that of a single Operational Amplifier and two channels.
• Built-in single power supply to dual power supply chip, so that it has the effect of dual power supply under single power supply
• Use large-capacity filter capacitors with rectifier circuit, which can be used for both AC and DC
• R1, R5 are the magnification setting resistors (the default is about 5 times magnification for delivery, you can change the magnification according to your own needs, the resistance can be selected from 5k-100k, the larger the resistance, the higher the magnification, if you use a plug-in resistor , you can remove the original chip resistor by soldering, and solder the plug-in resistor on the pads at both ends of the patch position)
