ZK-PR01 HIFI Front Tone Board Stereo Subwoofer Operational Amplifier JRC2068 AMP Wuzhi Audio Music
Add tone control to a DIY stereo and subwoofer audio project with the ZK-PR01 front-stage board. It uses a JRC2068 operational amplifier and is intended to work with a compatible power amplifier.
This is a preamp and tone-control component, not a standalone speaker power amplifier. Confirm the input/output wiring, required supply current and compatibility with your power amplifier before connection. The supplier labels a value of 28mA as “dissipation power”; because that label and unit do not agree, confirm the actual electrical specification in the model documentation. Use a suitable DC power supply within the stated voltage range.
