AD828 Audio OP AMP Moving Coil Microphone Preamps Pre-Amplifier Pre-amp Magnetic Head Phono Amplifier Board DC9-24V

Made using SMT technology, the power input has added a rectifier bridge, which can be used for both AC and DC. When inputting DC, there is no need to divide the positive and negative poles, making it more convenient to use. More stable performance.

 

 

 

There are currently two versions developed:

 

 

 

NE5532 ordinary operational amplifier version

 

 

 

AD828 fever operational amplifier version

 

 

 

NE5532 version: It adopts a brand new original Texas NE5532 operational amplifier chip and uses a round hole 8-pin IC socket, making it easy to upgrade the operational amplifier chip.

 

 

 

 

 

AD828 version: It uses a chip mounted operational amplifier. If you want good results but do not want to replace the operational amplifier chip, it is better to choose this option.

 

 

 

Except for the operational amplifier chip, the other materials used in the two versions are basically the same: the input coupling capacitor uses an imported brand of polar capacitor, the board uses a single power supply, and there is a voltage stabilizing chip, which is convenient to match with a single power supply amplifier.
