There are two common standards for line level: +4dBV for professional audio equipment and -10dBu for consumer-level products. Purpose Because input voltages from microphones, preamps, DIs, and instrument outputs can differ dramatically in level, they must be adjusted to a common level for use in other equipment such as mixers, recorders, and signal …

+4 dBu is "professional" line level, common in modern pro recording gear, and it is about 1.25 V. 0 dBv is an average line level, typical output from rackmount guitar/bass preamps. -10 dBv is "consumer" line level, common with older and cheaper recording gear. -20 dBu is roughly in the neighborhood of a typical instrument's output.

Professional audio equipment adheres to the professional line-level standard that is technically +4dBu (Sorry!), commonly referred to as just +4. Back in the days when we used tape machines and consoles, we aligned all the machines so that an input or output level of +4dBu translated to 0 on the VU meters.

Professional line-level 0dB is -or was, when first thought of - 1mW into 600Ω, which means 0.775v RMS or 1.09v peak, 2.18v p-p But you then need some headroom, and setting zero-level to 18dB below digital maximum means the kit should handle 10v p-p
