How do you work a sound board mixer?

Working a sound board mixer involves setting and controlling various audio levels and effects to manage the different sources of sound in a performance, live event, recording, or broadcast environment. Here is a general guide on how to work a sound board mixer:

1. Input Channels:

- Identify the input channels on the mixer where your audio sources will be connected. These channels usually have input jacks (such as XLR or TRS) and gain controls.

- Connect your audio sources (e.g., microphones, instruments) to the appropriate input channels.

2. Gain Control:

- Adjust the gain control for each input channel. The gain determines the level of the incoming signal. Adjust it until you achieve a healthy signal level without distortion.

3. Panning:

- Use the pan controls on each channel to position the sound source in the stereo field. Set the balance between left and right speakers for each input.

4. EQ (Equalization):

- Many mixers have EQ controls for each channel, allowing you to adjust the frequency response of the sound. Use these to cut or boost specific frequencies to enhance or correct the sound.

5. Auxiliary (AUX) Sends:

- AUX sends allow you to route an audio signal from the mixer to an external device, such as a monitor speaker or an effects processor. Adjust the AUX send levels for each channel as needed.

6. Effects:

- If your mixer has built-in effects (such as reverb, delay, chorus), you can use the controls on the mixer to adjust the effect parameters and apply them to specific channels.

7. Main Output:

- Set the main output level(s) to control the overall volume of the audio sent to the main speakers or recording devices.

8. Subgroups and Master Fader:

- Some mixers have subgroups that allow you to group multiple input channels together. Adjust the subgroup faders for better level control. The master fader controls the overall level of all channels.

9. Monitoring:

- Use the monitor section of the mixer to listen to individual channels or use headphones to monitor the overall mix.

10. PFL (Pre-Fader Listen) and Solo:

- These functions allow you to listen to a specific channel's signal independently of the main mix. Use them for troubleshooting and adjusting levels.

11. Muting and Fader Automation:

- Use the mute buttons to silence individual channels when not needed. Some mixers also have fader automation capabilities for recording level changes.

12. Practice and Familiarization:

- Spend time experimenting with the mixer's controls to understand how they affect the sound. Each mixer can be slightly different, so it's important to become familiar with its features.

Remember that sound board mixing requires practice and experience. Start with simple setups and gradually work your way up to more complex scenarios. Always ensure that your input levels are appropriate to prevent distortion and unwanted feedback.
