Product description:
Using the patch process, the power input to increase the rectifier bridge, can AC and DC, the input DC do not have points positive and negative, and more convenient to use. Performance more stable, with the volume potentiometer.
NE5532 version: the use of new original NE5532 op amp chip, the use of round hole 8 feet IC socket, easy to upgrade the op amp chip.
PCB size: 50mm X 33mm
Working voltage: DC 9v-24v
AC: 8v-16v
Note:
R7, R5 is the magnification set resistance (delivery default is about 5 times to enlarge) can change according to their own needs, the resistance can be selected from 5k-47k, the greater the resistance, the higher the magnification, if it is a plug resistor , You can remove the original chip resistors, the plug-in resistance welding in the patch position on both the reserved pad.
Package included:
1PC NE5532 Op Amp Preamplifier Board With Volume Potentiometer
