NE5532 Preamplifier Audio Input: Line OPAMP Chip: Dual NE5532 Power Supply: Dual AC12V15V Overview This NE5532 Preamplifier provides dedicated linelevel amplification using a dual NE5532 opamp. It is designed to boost line signals for downstream equipment while maintaining signal integrity. The unit is powered from dual AC supplies in the range of 12 to 15 volts. Key benefits Improves drive for linelevel sources by providing a clean, dedicated preamplification stage. Uses a proven dual NE5532 opamp for reliable audio performance and stable operation. Simple integration in an audio chain between line sources and amplifiers or active speakers. Important attributes Function: Linelevel preamplification to condition and raise the level of line signals before further processing or amplification. Compatibility: Suitable for line outputs from CD players, DACs, audio interfaces, and mixers, feeding into power amplifiers or active speakers. Size and material: Not specified in the provided details. Performance: Built around a dual NE5532 opamp with a dual AC power supply requirement (AC12V15V). Use scenarios Home studio or project room: Connect a computer audio interface or DAC line output into the NE5532 Preamplifier, then route the signal to a mixer or power amplifier for recording or monitoring. HiFi or home audio: Insert the preamplifier between a CD player or streaming DAC and an integrated amplifier to ensure adequate linelevel drive and consistent signal levels. DIY or educational setup: Use as a modular preamp stage in a custom enclosure or learning bench to study linelevel amplification and opamp behavior with a straightforward, welldocumented circuit.
