Q & A

What is the advantage of using a center sub array in audio setups?

A center sub array is preferred indoors because it is more forgiving in terms of sound distribution, filling gaps caused by walls and reverberation.

How should speaker input levels be set for optimal sound quality?

Speaker inputs can generally be set to noon or unity, allowing adjustments to the master output at the console to suit the event's needs.

What should be done if front fills are added to the audio setup?

If front fills are used, they should be set to about 10 dB lower than the main speakers to ensure balanced sound across the audience.

Why does sound intensity vary for audience members seated at different distances?

Sound intensity varies due to the distance from the speakers; for example, the front row hears sound much more directly than those in the back, leading to a 5 to 6 times difference in sound travel distance.

What is a recommended position for mixing audio during a live event?

It is advisable to stand at the midpoint of the audience, preferably starting from house left, to achieve the best balance in sound quality.

What are some practical speaker options mentioned in the tutorial?

The QSC K12 and the smaller CP8 speakers are recommended for quality sound without breaking the bank, as they are effective for different audio needs.

What should be considered if there are obstacles in speaker placement?

Flexibility is key; understanding audio principles allows you to adapt to challenges, such as equipment height limitations or stage placement issues.

What does the presenter mean by 'subdivide and conquer' in terms of audio aiming?

'Subdivide and conquer' refers to aiming speakers accurately through the middle of the audience area to ensure even sound distribution and coverage.

How can one improve sound coverage at an event when facing physical constraints?

Improving sound coverage may involve raising the trim height of speakers or moving the stage back to allow speakers to be farther away from the audience.

What is the purpose of the spreadsheet mentioned in the tutorial?

The spreadsheet is a resource for users who want to get detailed calculations for speaker placement and setup, enhancing their understanding and application of audio principles.
