AUTOMIXER Screen

Channel display select buttons

Displays the automix gain meters and mode indicators (manual (yellow), auto (green), or mute (red)) for each channel. Press one of these buttons to select channels to be displayed in the channel control field below.

OVERRIDE/PRESET/MUTE buttons

These buttons are used to set up each group (a/b/c/d/e) selected in the channel control field. Only the buttons for the selected groups will be displayed.

• OVERRIDE
• Press this button to smoothly fade-in the levels of the channels (for which the override buttons are turned on) to 0 dB (unity gain). All channels for which the override buttons are turned off will be muted.
• PRESET
• Press this button to place the corresponding group of channels into a mode (manual, auto, or mute) as indicated next to the lit preset indicator.
• MUTE
• Press this button to fade out all channels immediately (in 0.5 seconds).

reset button

Initializes the Automixer settings.

meters button

Switches the meter indicators displayed in the channel control field. Pressing the button repeatedly will switch among gain (automix gain), input (input level), and output (output level).

Level indicator

Lights up green when the audio signal reaches the level appropriate for automatic mixing.

Meter indicator

The meter indicator features three display modes. The mode will change each time the meters button in the master field is pressed.

gain (Green): Displays the Automixer gain

input (Yellow): Displays the input level

output (Blue): Displays the output level

weight

The weight adjusts the correlated sensitivity between input channels. Balance the weight controls so that the automix gain meters display approximately equal levels when no one is talking. For example, if there is ongoing noise near one microphone (e.g., computer fan or air vent), suppress it by reducing that channel’s weight. To change the channel’s weight setting, use the [TOUCH AND TURN] knob to adjust the weight slider.

Automixer calculates the ratios of the input levels of a specific channel against all input channels within the group. The following example explains how the weight control works.

■ Raising the weight control for one channel:

• Increases that channel’s automix gain, and slightly decreases the automix gain on other channels.
• Channels with higher weight settings are more likely to gain automix gain (making it easier to be heard) than other channels.

■ Lowering the weight control for one channel:

• Decreases that channel’s automix gain, and increases the automix gain for other channels.
• Makes it more difficult for that channel’s mic to be differentiated from others when people are speaking on multiple microphones at the same time.

group

Each channel can be assigned to one of five groups (a/b/c/d/e). This group function is helpful in the following applications:

• When using multiple rooms: Assign the microphones in each room to different groups so that they can function as separate automixers.
• Stereo panning: Assign the microphones panned left, right, and center to separate groups to maintain a stable stereo presence.

override

Turning on the OVERRIDE button in the master field will place the corresponding channels into man mode or mute mode, depending on the override button status of the channel.

• When the channel’s override buttons are on, turning on the OVERRIDE button in the master field will place the corresponding channels into manual (man) mode.
• When the channel's override buttons are off, turning on the OVERRIDE button in the master field will place the corresponding channels into mute mode.
• Turn off the Master OVERRIDE button to restore the previous mode for that channel.
• The Override function is useful when the panel discussion leader wants to control the system.
• Follow the steps below.
• 1. Turn on the OVERRIDE button on the channel for the leader.
• 2. Turn off the OVERRIDE button on all other channels.
• 3. Turn on the OVERRIDE button in the master field as necessary.

Channel number

The channel number and channel name to be inserted are displayed.

Press to set the channel to be inserted.

preset button

Press this button to select a channel mode (man, auto, or mute) that will be engaged if the PRESET button in the master field is turned on. The indicator will light up indicating when preset has been programmed for that channel.

man/auto/mute buttons

Switches between man/auto/mute.

man: There is no automixing, and the audio signal passes through at unity gain. Use this mode for singing through a microphone.

auto: Automixing is turned on. Use this mode for dialog or speeches.

mute: The channel’s output is muted.
