This is a DIY assembly kit for a Hi-Fi preamplifier, based on the well-regarded NE5532 operational amplifier.
The board is designed to provide comprehensive audio tone control for custom sound system projects.
Key Features
- Features four-channel adjustment controls for Volume, Treble, Mid, and Bass .
- The power supply circuit incorporates a full-bridge rectifier, designed to effectively filter high-frequency interference from the AC mains.
- Supplied as a complete DIY kit, requiring component soldering and assembly.
Power Requirements
This board requires a dual 12-15V AC transformer for operation.
Please Note: It cannot be powered directly by a 12V battery or a standard DC power source.
Features:
NE5532 is a high-performance, low-noise, dual operational amplifier integrated circuit (IC).
Excellent potentiometers. No crackle caused by poor contact and internal resistance instability.
Output socket adopted double hope socket. Good contact and long service life.
Dual and regulated power supply.
