Is it better to have high or low mc voltage

Depends on the application scenario and device requirements.

1. Higher MC voltage can provide higher output power and greater signal strength, thus improving the performance and reliability of the device. In audio or video systems, high MC voltage can provide better sound and image quality.

2. A low MC voltage provides better stability and reliability, and reduces power consumption and heat generation in the device. In precision instruments or medical equipment, low MC voltage can reduce the error and failure rate of the equipment and improve the stability and reliability of the equipment.
