    When talking about the Gating Automatic Mic Mixer, what is Noise Floor Tracking?

    • The mixer's ability to adjust the open threshold level above the slowly-changing level of background noise.

    • The mixer's ability to keep track of particularly troublesome echoes that are the result of a concrete floor.

    • The mixer's ability to notice the change of background noise in a room and send an alert when the noise reaches a predetermined level.

    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.

    When talking about the Gating Automatic Mic Mixer, what is ID Gating?

    • The mixer's ability to identify which microphone is the primary source for a talker who is loud enough to open multiple microphone thresholds.

    • The mixer's ability to only open a microphone channel based on the voice-print identification of an authorized user.

    • The mixer's ability to judge the text labels applied to each channel and give priority to the channels that sound more important.

    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.

    Multiple Choice: What does the Side-Chain Filter field do in the Automatic Mixer’s properties panel?

    • Toggles the availability of a bandwidth/frequency selector in the mixer’s control panel

    • Enables multiple Automatic Mixers to be “daisy-chained” together

    • Adds an additional output pin to the component that can be wired to control devices

    Correct Answer
    A. Toggles the availability of a bandwidth/frequency selector in the mixer’s control panel
    Explanation
    The Side-Chain Filter field in the Automatic Mixer's properties panel allows the user to toggle the availability of a bandwidth/frequency selector in the mixer's control panel. This means that when the field is enabled, the user will have the option to adjust the bandwidth or frequency of the side-chain filter in the mixer. This can be useful for controlling the audio processing and filtering in the mixer, allowing for more precise and customized sound adjustments.

    Multiple Choice: What does the Hold Time knob adjust?

    • The length of time that a channel will stay open after it drops beneath the Open Threshold level

    • The length of time it takes for the Mixer to apply the proper attenuation to an open channel

    • The length of time that a channel must reach its Threshold for its gate to be opened

    Correct Answer
    A. The length of time that a channel will stay open after it drops beneath the Open Threshold level
    Explanation
    The Hold Time knob adjusts the length of time that a channel will stay open after it drops beneath the Open Threshold level. This means that once the channel's signal level falls below the Open Threshold, the Hold Time determines how long the channel will remain open before it closes again.

    Multiple Choice: What does NOM stand for?

    • Number of Open Mics

    • Number Of Mics

    • Number of Mix

    Correct Answer
    A. Number of Open Mics
    Explanation
    NOM stands for Number of Open Mics. This acronym is commonly used in the context of live performances, particularly in the music industry. It refers to the total number of microphones that are available for use during an event or a specific performance. By knowing the NOM, event organizers and performers can plan accordingly and ensure that there are enough microphones for all participants or performers.

    Multiple Choice: If a very quiet person is speaking into a microphone and it is not loud enough to reach the Open Threshold of a Gain-Sharing Automatic Mixer, how could you compensate for this?

    • Raise the Priority Gain knob of the channel in question

    • There is no way to compensate for this, you must ask the person to speak louder

    • Raise the Open Threshold of the entire Mixer

    Correct Answer
    A. Raise the Priority Gain knob of the channel in question
    Explanation
    To compensate for the quiet person speaking into the microphone, you can raise the Priority Gain knob of the channel in question. This will increase the gain specifically for that channel, amplifying the sound and making it louder. By adjusting the Priority Gain, you can ensure that the quiet person's voice reaches the Open Threshold of the Gain-Sharing Automatic Mixer, allowing it to be heard properly.

    Multiple Choice: What does the Depth knob adjust?

    • How much attenuation is applied to closed channels

    • The number of available channel input pins on the component

    • The maximum amount of gain to be shared amongst channels

    Correct Answer
    A. How much attenuation is applied to closed channels
    Explanation
    The Depth knob adjusts the amount of attenuation that is applied to closed channels. Attenuation refers to the reduction in signal strength or amplitude. By adjusting the Depth knob, the user can control the level of attenuation for the closed channels, allowing them to fine-tune the audio output and balance between open and closed channels.

    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?

    • Detector Time

    • Signal Presence

    • Side-Chain Filter

    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.

    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.

    • True

    • False

    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.

    Rate this question:

    What does the "Default" button do in the Gating Automatic Mic Mixer?

    • It determines which channel will remain open when no channels are gated open

    • It deactivates the Fault LED when an error has been detected in the Mixer

    • It will return all the threshold settings for a channel back to its default state

    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.

    Multiple Choice:Which knob adjusts the amount of attenuation that is applied to all channels when none are open?

    • Rest Gain

    • Threshold Level

    • Closed Level

    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.

    Rate this question:

  • 17. 

    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?

    • Channels are given arbitrary priority from left to right

    • The channel that has the lowest gain will be gated closed

    • The channel that has reached its threshold the longest is gated closed

    Correct Answer
    A. 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.
