Multiple Choice:Which field determines how long an audio signal must be present in order to count as a viable source for opening a gate?
Correct Answer
A. Detector Time
Explanation
The field that determines how long an audio signal must be present in order to count as a viable source for opening a gate is the Detector Time. This parameter sets the duration that the audio signal needs to exceed in order for the gate to open and allow the signal to pass through.
14.
Multiple Choice:Which knob adjusts the amount of attenuation that is applied to all channels when none are open?
Correct Answer
A. Rest Gain
Explanation
The knob that adjusts the amount of attenuation applied to all channels when none are open is the Rest Gain knob. This knob allows for controlling the overall level of attenuation when no individual channels are active or open. It helps to set a baseline or resting level for the audio signal before any further adjustments are made.
15.
Multiple Choice:If more mics are above their threshold than the Max NOM field will allow to be open, how does the Mixer decide which channels are opened and which are not?
Correct Answer
C. The channel that has reached its threshold the longest is gated closed
Explanation
The mixer decides which channels to open and which to close based on the channel that has reached its threshold the longest. This means that if more mics are above their threshold than the Max NOM field allows, the channel that has been above its threshold for the longest period of time will be closed or gated. This prioritizes the channels that have been above their threshold for a shorter duration, allowing them to remain open.
16.
What does the "Default" button do in the Gating Automatic Mic Mixer?
Correct Answer
A. It determines which channel will remain open when no channels are gated open
Explanation
The "Default" button in the Gating Automatic Mic Mixer determines which channel will remain open when no channels are gated open. This means that when no channels meet the gating criteria, the "Default" button decides which channel's audio will still be heard.

When talking about the Gating Automatic Mic Mixer, what is Noise Floor Tracking?
Correct Answer
A. The mixer's ability to adjust the open threshold level above the slowly-changing level of background noise.
Explanation
Noise Floor Tracking refers to the Gating Automatic Mic Mixer's ability to adjust the open threshold level above the slowly-changing level of background noise. This means that the mixer can adapt and set the appropriate level for when the microphones are activated, taking into account the varying background noise in the environment. By adjusting the open threshold level, the mixer ensures that only relevant audio signals are captured and transmitted, while minimizing the pickup of unnecessary noise.
18.
True or False: When a channel is Manually opened in the Gating-Automatic Mic Mixer, it does not count against the allowable number of open mics.
Correct Answer
A. True
Explanation
When a channel is manually opened in the Gating-Automatic Mic Mixer, it means that the channel is manually activated and not controlled by the automatic gating feature. Therefore, this manually opened channel does not count against the allowable number of open mics, as it is not part of the automatic mic mixing process.
19.
When talking about the Gating Automatic Mic Mixer, what is ID Gating?
Correct Answer
A. The mixer's ability to identify which micropHone is the primary source for a talker who is loud enough to open multiple micropHone thresholds.
Explanation
ID Gating refers to the mixer's ability to identify which microphone is the primary source for a talker who is loud enough to open multiple microphone thresholds. This means that when multiple microphones are picking up sound, the mixer can determine which microphone is capturing the primary audio source and prioritize it over the others. This helps in ensuring that the primary talker's audio is clear and not overshadowed by other ambient noises or secondary sources.
