Q-sys Level One Training: Automatic Mixers (Version 1)

The mode in which a channel is only opened if it has been assigned a higher value than the other open channels on the same mode is called "priority mode".

To change the number of input channels in an Automatic Mixer, you need to select the component and go to its Properties panel in the Right-Side Pane. From there, you can adjust the Channels field to the desired number of input channels. This allows you to customize the mixer according to your specific needs and requirements.

An Open LED on the Automatic Mixer's control panel indicates that the gate of the associated channel is open. This means that the signal from that channel is currently being allowed to pass through and is being mixed with the other signals.

In the Designer software, the Gain-Sharing and Gated Automatic Mixers can be found in the Schematic Library under the category of Audio Components > Mixers.

The available modes of a channel in the Gated Automatic Mixer are Automatic, Priority, and Filibuster. The Automatic mode allows the mixer to automatically switch between channels based on audio activity. The Priority mode gives priority to specific channels, ensuring they are always heard over others. The Filibuster mode allows a specific channel to continuously transmit audio, overriding other channels.

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 channel will remain open for the duration set by the Hold Time knob before closing again.

NOM stands for Number of Open Mics. This acronym is commonly used in the context of live performances, particularly in comedy or music, to refer to the total number of open microphone slots available for performers. It is a measure of how many individuals or acts can participate in an open mic event.

The primary difference between the Gain-Sharing Automatic Mixer and the Gated Automatic Mixer is that the Gain-Sharing mixer actively shares gain across multiple open channels, while the Gated mixer gives more options on the criteria for which a channel is opened. In other words, the Gain-Sharing mixer focuses on distributing gain among open channels, while the Gated mixer allows for more flexibility in determining which channels are opened based on certain criteria.

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 Side-Chain Filter is enabled, the user can adjust the bandwidth or frequency of the mixer's output signal, allowing for more precise control and customization of the audio output.

If Channel 2's mode is changed to Automatic, it means that it will open when it reaches its threshold. Therefore, if Channel 2 is already reaching its threshold but not open, changing its mode to Automatic would cause Channel 2 to open.

The Depth knob adjusts the amount of attenuation applied to closed channels. This means that when a channel is closed or not in use, the Depth knob controls how much the signal is reduced or attenuated. This can be useful in situations where certain channels need to be muted or have their volume reduced.

The field that determines how long an audio signal must be in order to count as a viable source for opening a gate is the Detector Time. This means that the gate will only open if the audio signal surpasses the specified duration set in the Detector Time field.

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 or volume specifically for that channel, allowing the person's voice to be amplified and reach the Open Threshold of the Gain-Sharing Automatic Mixer.

The Rest Gain knob adjusts the amount of attenuation that is applied to all channels when none are open. This means that it controls the overall volume or level of all channels when they are closed or not in use. By turning the Rest Gain knob, the user can increase or decrease the amount of attenuation applied to all channels, resulting in a higher or lower overall volume level.

The statement is false. When linear attenuation is highlighted, one attenuation step is applied every time that the number of open mics halves, not doubles.

The mixer decides which channels are opened and which are not by giving them arbitrary priority from left to right. This means that the channels are prioritized based on their position, starting from the leftmost channel and moving towards the right.

The possible explanation for the given scenario is that the channel is set to Priority Mode, as is another channel which is open and has a higher priority. Additionally, it could be set to Filibuster Mode, as is another channel which is already open. Lastly, there are already as many channels open as the Max NOM will allow, and they are all further to the left.

If Channel 2 is reaching its threshold but is not open, changing it to Priority Mode would not cause it to open. This means that the priority mode does not prioritize the opening of Channel 2 over other channels. Therefore, Channel 2 would stay closed even after changing it to Priority Mode.

If four channels were to reach their threshold, each channel would experience an attenuation of 10 dB.

If four channels were to reach their threshold, each channel would experience an attenuation of 6 dB.

If four channels were to reach their threshold, each channel would experience an attenuation of 8 dB.

If Channel 1's mode is changed to Priority, it means that it will have higher priority over the other channels. Therefore, when Channel 1 reaches its threshold, it will open and take precedence over Channel 3, causing Channel 3 to close.
