Description of Product: The PCB size of this headphone amplifier board is 100X72X1.6MM, with a 1OZ copper spray process.

The classic circuit RA1 is used in this version, utilizing the power adapter power supply (18-24V) to provide positive and negative power supply to the JRC4556AD through the IC differential. Alternatively, two 9V batteries can be used with the lead-off electrolytic capacitor.

The board features two sets of resistors. The standard version offers 1x magnification, suitable for 8-32 ohm high-sensitivity headphones. The 4x magnification version is designed for medium and high-impedance headphones (above 90DB).

This headphone amplifier board can be powered by either batteries or a power adapter.

Packaging includes: 1HV-10-RA1 Headphone Amplifier Board with PCB size: 100X72X1.6MM, featuring a 1OZ copper spray process. It contains two sets of resistors and is compatible with both battery and power adapter power sources.
