What is +4dbu vs -10dbv?

+4dbu refers to a professional line-level reference level typically used in pro audio equipment, where 0dBu is the maximum level signal that can be transmitted without distortion. +4dBu corresponds to 1.23 volts RMS. It offers a higher level and better signal-to-noise ratio compared to -10dBV.

On the other hand, -10dBV is a common consumer line-level reference level typically used in home audio equipment. -10dBV corresponds to 0.3162 volts RMS, and it is used to ensure compatibility with consumer audio equipment. It has a lower output level and SNR than +4dBu.

The main difference between +4dBu and -10dBV is the signal level. +4dBu provides a higher signal level and a better SNR, making it more suitable for professional studios, live sound reinforcement, and broadcast applications. In contrast, -10dBV is ideal for consumer audio gear, such as home theaters, headphones, and portable devices.
