Accepted Answer

HDBaseT over Cat6 cable

Question 3

In a conference room with significant ambient noise, which microphone polar pattern is MOST appropriate for capturing a single presenter at a podium?

Accepted Answer

Hypercardioid

Answer

A hypercardioid pattern has a narrower pickup angle than cardioid, providing better rejection of ambient room noise while focusing on the presenter.

Answer

Gain structure is the practice of setting each component's input and output levels to maintain the best signal-to-noise ratio throughout the entire signal chain.
