Question 1

What is the primary advantage of using balanced audio cables (XLR) over unbalanced cables (RCA/TS) in corporate video productions?

Accepted Answer

Balanced cables cancel out electromagnetic interference and noise over long runs

Answer

Balanced cables carry a higher voltage signal

Answer

Balanced cables support digital audio signals natively

Answer

Balanced cables are lighter and more flexible for field use

Question 2

In corporate video audio, what is 'sync sound'?

Accepted Answer

Audio recorded simultaneously with the video image, intended to be used as the primary sound

Answer

Music that is synced to match scene transitions

Answer

A post-production technique for aligning sound effects to action

Answer

The process of matching timecode between audio recorders and cameras

Question 3

Which type of microphone polar pattern picks up sound equally from all directions and is useful for recording group discussions in corporate video?

Accepted Answer

Omnidirectional

Answer

Cardioid

Answer

Hypercardioid

Answer

Figure-8 (Bidirectional)

Question 4

What is the role of a 'noise gate' in corporate video audio post-production?

Accepted Answer

It mutes or attenuates audio signals that fall below a set threshold, reducing unwanted background noise between speech

Answer

It boosts audio signals that fall below a certain volume threshold

Answer

It limits audio peaks to prevent clipping above a set threshold

Answer

It applies spatial reverb to simulate large room acoustics

Question 5

For a corporate video where the presenter will be moving around, which microphone setup is most practical?

Accepted Answer

Wireless lavalier (body pack) microphone system

Answer

Mounted overhead condenser microphone

Answer

Hardwired lavalier microphone

Answer

Handheld dynamic microphone on a stand

Question 6

What does 'phantom power' (48V) supply in a corporate video audio setup?

Accepted Answer

Provides electrical power to condenser microphones through the XLR cable

Answer

Powers wireless microphone transmitters and receivers

Answer

Boosts the audio signal level to line level from microphone level

Answer

Supplies power to active DI boxes used with electric instruments

Question 7

During a corporate video shoot in a reverberant space, which acoustic treatment approach is most practical to improve dialogue clarity?

Accepted Answer

Hanging sound-absorbing panels or blankets on nearby walls and surfaces to dampen reflections

Answer

Moving the microphone farther away from the speaker to capture more ambient sound

Answer

Increasing the microphone gain to compensate for the room echo

Answer

Using a wider microphone polar pattern to capture more direct sound
