Description
Stereo MIC Preamp Dynamic Microphone Stereo Preamp 5532 Op Amp Magnetic Head Phono Preamplifier Board NE5532
Product Description
Stereo amplifier board: suitable for dynamic microphones, used as deck heads, preamplifiers for electrophonic heads, and vinyl preamplifiers. The latest upgrade and revision: The rectifier circuit is added, which can be used for both AC and DC. The DC input does not need to be divided into positive and negative poles. It uses the original Texas NE5532 (with a gold-plated round hole IC socket for easy upgrade of the op amp) for the dynamic microphone preamp Amplify, can also be used as deck head, phono head pre-amplification, vinyl pre-amplification. Note: If it is used as a deck head, a phono head pre-amplifier, a vinyl pre-amplifier requires a 0.01-0.1UF capacitor in parallel with the input end to ground to attenuate noise and increase low frequency (the capacitance capacity is determined by the head impedance and personal feeling the size of).
Specification
NE5532 dynamic microphone stereo preamplifier board, magnetic head, phono head amplifier board
value
Working voltage
AC: 6-17v or DC: 9V-24V
Board size
50mm*33mm
Remarks
1: If you need low voltage power supply, you can replace a low voltage op amp chip by yourself. 2: If only one channel is needed, the input of the other channel needs to be short-circuited with GND (to avoid interfering signals)
