Workflow
Using an analogue mixing desk
Learn how signal flows through a generic analogue desk, then practise setting gain, EQ, effects sends, channel faders, and the stereo master output.
Understanding the signal path
An analogue mixing desk receives audio through separate input channels. Each channel strip provides controls for preparing and shaping that signal before it joins the mix. Although desks vary, a common path is input, gain or trim, equalisation, auxiliary or effects send, channel fader, and master output. Learning this order helps you identify where a level or sound is being changed.
1. Set the input gain
The gain or trim control sets the level entering the channel. Ask the performer to produce the loudest level expected, then raise the gain while watching the input meter. The signal should be strong and clear without reaching overload or clipping. Input gain is not the same as the channel fader: gain prepares the incoming signal, while the fader balances that channel against the rest of the mix.
2. Shape the sound with EQ
Equalisation controls boost or cut frequency ranges. A simple desk may provide high, mid, and low controls. Start with the controls at their centre position, listen to the source in context, and make small changes for a clear purpose. Cutting an unwanted frequency is often more controlled than applying a large boost. Avoid adjusting EQ only because a control is available.
3. Send signal to an effect
An auxiliary or FX send routes a controlled amount of the channel signal to an effects processor, such as reverb or delay. The processed signal returns to the desk and is blended with the dry channels. This allows several channels to share one effect while each send control sets a different amount. Too much effect can reduce clarity and make the mix sound distant.
4. Balance channels with the faders
A channel fader controls how much of that channel reaches the main mix. The 0 dB mark is normally the unity-gain position, where the fader neither boosts nor reduces the channel output. Build a balance by listening to all channels together rather than setting each one in isolation. Leave enough headroom so that combined signals do not overload the master output.
5. Control the stereo master output
The master faders control the final level leaving the desk. On a stereo desk there is usually a left and right master path. Keep both sides matched unless there is a deliberate technical reason not to. If the master meters overload, reduce excessive channel levels and review the mix rather than relying only on pulling down the master faders.
Practical workflow
Before mixing, label every channel and trace its signal path. Set safe input gains, place EQ controls at their neutral positions, and begin with effects sends low. Bring channel faders into the mix one at a time, listen for balance and clarity, then check the master meters. Make one controlled change at a time and listen to its effect before moving to the next control.

Explore a channel fader
Move the fader to change the channel's contribution to the mix. The 0 dB position is unity gain: the fader is neither boosting nor reducing the signal. Pulling it down reduces the output level.
Current setting
0 dB
A fader controls the output level of its channel. It is different from the input gain control, which is set near the start of the signal path to establish a clean recording or input level.
Try setting the fader to 0 dB, then compare −10 dB and −30 dB. Keyboard users can focus the slider and use the arrow keys.

Build a three-channel mix
Each vertical strip represents one input channel. Work from the top down: set input gain, shape the tone with EQ, choose how much signal is sent to an effect, then balance the channel with its fader. The master faders control the final left and right outputs.
Drag a rotary control up or down to turn it. You can also focus any control and use the arrow keys. Double-click a knob or fader to reset that control.
The three sources are panned across the stereo field so the left and right master faders can be heard independently.
Signal-path order
Input → gain/trim → EQ → auxiliary or FX send → channel fader → master output.
What to listen for
Aim for a clean input without overload, useful rather than excessive EQ, controlled effects, and a balanced final mix.
This simplified desk uses generated tones to demonstrate control and routing relationships. It is not a model of analogue console circuitry, and real desks may use different layouts or routing options.
Key tips
- Set input gain before balancing the mix with channel faders.
- Make small EQ changes and compare them with the unprocessed signal.
- Use effects sends carefully so the mix remains clear.
- Check channel and master meters regularly to avoid overload.
