What voltage is audio line level? A line level signal is approximately one volt , or about 1,000 times greater than a mic level signal. One volt is also expressed as 0 dBV – so a line level signal is about 40 to 60 dB higher than mic level.

An Overview of Audio Levels. There are three main Audio Levels that are worth knowing about: Microphone Level; Line Level; Speaker Level; The determining factor here is the voltage which runs them. Speaking into a microphone only produces a few thousandths of a volt, but loudspeakers need a whole bunch of volts to make their big magnets move. What is Mic Level?

https://electronics.stackexchange.com/questions/298573/understanding-voltage-levels-on-3-5-mm-audio-output
When no audio is playing, there's a voltage of about 2 mV. When I output a constant audio signal, the voltage rises initially to 0.5 V, but drops back to 2 mV after 2-3 seconds. What purpose does this 2 mV bias voltage serve? Does audio output circuitry usually contain DC blocking capacitors, or is DC blocked via some other means? audio headphones

While "line level" audio is typically 1 mW into 600 Ω, and this comes out to 1.1 V p for a sine, audio is far from a sine. Even if the spec is adhered to and you only get 775 mV RMS on average, the peaks can be considerably higher than 1.1 V. It is generally good to accept and handle without distortion peaks up to ± 5 V at least. Share

A quick shufty at the specifications pages of some audio equipment will show that 'line levels' can vary between 0.1 and 1 volt in normal operation. Don't forget that impedance level also play a part 600 ohms, 47k ohms or 10k ohms being common input values. This applies to both domestic and professional equipment.

As we can see from the chart, this will require a doubling of power from the amplifier, which will now be churning out 50 peak watts to produce a loudness of 83dB. If we want to double the apparent volume from our original level we will need to create 9OdB of sound pressure, requiring 250 peak watts.
