Unity Gain

Unity gain is a term used when establishing the balance between pieces of audio equipment. The idea is that input should equal output, level-wise. Audio that goes into a device at one level and comes out of that device at the same level is said to be at unity gain. The devices can be as simple as a guitar amplifier and a mic or as complex as a chain of interacting equipment.

 

 

In the concept of unity gain, the input and the output between two devices are at the same level. That's to say, when a microphone is outputting a gain of factor 1, which is equivalent to 0 dB, the mixer also outputs at 0 dB. The input and output are at the same voltage and impedance. Unity gain is established by calibrating two pieces of equipment to interact at the same level.

 


Frequently, the best way to set unity gain is to adjust a microphone or line signal gain to 0 dB, measured both at the preamp and output stage, and then match that 0 dB level simultaneously on the input of the second piece of equipment—whether an amplifier, recording software or mixer.

 

 

*Unity gain is useful for several reasons:

- It gives a significantly cleaner and undistorted signal. If each piece of gear in an audio studio adds even a tiny bit of distortion, the accumulated effects degrade the signal.

- Microphones sound much fuller and have much better dynamic range.

- It is easier to apply outboard effects, as most effects units are set to accept a unity signal.

***Excerpts from ThoughtCo (by Joe Shambro, https://www.thoughtco.com/what-is-unity-gain-1817673) 

 

 

▲ If the difference in gain value for each stage is large, an unstable voltage occurs, which affects the signal of the next stage, resulting in a distortion of the sound. Increasing gain stably is a desirable setting.
