NE5532 Preamp Board - DC 9-29V HiFi Audio Preamplifier Module for Speaker System

VOKTTA. 1. Adopting TINE5532 three piece design, it has primary gain, buffering, and tone processing functions. 2. Silent circuit design for power on/off, effectively avoiding impact noise during power on/off. 3. Supports DC9-29V wide voltage stable input, with positive and negative polarity reverse protection function. 4. Built in boost module, single power supply can be converted into dual power supply, with a large dynamic range. 5. Dual impedance output interface design, high impedance and low impedance meet the connection requirements of different power amplifier devices. Features: 1.
