Does a Mixer Improve Sound Quality?

Mixers or consoles are used in recording studios, live venues, and broadcasting applications to process audio. Does a mixer improve sound quality? Is the quality difference between entry-level portable mixers and multi-million-dollar studio desks?

In what ways do audio mixers affect the quality of sound? Audio mixers can affect the quality of the signals they pass through, just as any other device can. In addition to adjusting levels, panning, effects, and more, audio mixers color audio through gain stages, A/D and D/A converters (digital mixers), and signal paths.

The Roles Of Mixers & Their Sound

Does a mixer improve sound quality? All things audio used to revolve around mixers. Their influence on generations of music ranges from the Beatles to Pink Floyd, from single-channel recordings to 64-bit jukeboxes. It is no longer necessary to use them when making records today. While mixers are unique tone-shaping instruments, they will shape your signal differently based on your preferences.

As an example, let’s look at a situation. The whole movie Sound City was shot around a Neve mixing console owned by Dave Grohl (Nirvana, Foo Fighters, etc.). Here, Dave explains why he brought the Neve console to Foo Fighters’ studio. Does a mixer improve sound quality?

Audio Mixers Affect Audio Quality

The sound of an audio signal will be affected by all additional equipment it must pass through. As audio components/devices pass through conductors, the alternating current follows all electricity physics. Does a mixer improve sound quality?

Due to the mixers’ multiple components, the mixer will have multiple opportunities to “color” the signal. The simple act of passing through audio components will, by default, alter the signal, even if it isn’t audible.


Plugging in an instrument straight or a dynamic or ribbon microphone usually results in a shallow gain level reaching the mix. Does a mixer improve sound quality? Since levels need to be raised in the mix, every unwanted noise in the signal is amplified unless we’re referring to active circuitry in the instrument or microphone.

Every mixer input can be preamplified or gain staged with a single knob. So you can bring up the signal before it enters the tape or computer. There will be no need to adjust the volume afterward, so you’ll have a pristine-clear mix.


If I have an audio interface, do I need a mixer?

You don’t need a mixer if you already have an audio interface. For recording, the interface connects your microphones and instruments to your computer. You won’t need any additional devices to connect the components of your studio this way.

Is a digital mixer better than a digital audio workstation?

Digital mixers do not sound better than DAWs. The mixer effects are limited because they are enough to get by in a live sound or broadcasting situation. A DAW allows you to do much more with recorded audio. Third-party plugins can be used to manipulate the sound in various ways in the app.

Is it possible to replace a mixer with an audio interface?

For live sound reinforcement, an audio interface cannot replace a mixer. It can be used for small recording or streaming setups, such as a solo instrumentalist or one or two microphones. A suitable interface should have all of the inputs and outputs you need.


Does a mixer improve sound quality? Beginners with small home studios or basic recording needs might not need some of the features found in most mixers. Although this eliminates the need for a hardware audio mixer, we still recommend using music production software on your computer to mix.

A dedicated mixer can be unnecessary if you only record from one or two sound sources. Audio interfaces, however, are a different story. High-quality audio requires this device.
