Channel Settings
Under the Channel Settings tab in Output Processing (see Figure 19, lower half), the user can set a Label, Gain value, Delay
Value, Mute the Channel, and enable or bypass Parametric, U-Shaping, All Pass Filtering, and/or all EQ for a particular
output channel. Select the Output Channel to control via the drop-down menu or individual alphabetic channel buttons
above the plotter display.
•
The Label widget allows a user to enter a short text description of a Channel, Array Group, or Link Group. It is for
informational purposes only.
•
The Gain widget lets the user increase or decrease the signal level by decibels (dB). The default assumes negative gain
values. Entering any integer will result in the gain being set to the negative of that integer (e.g., “3” becomes -3 dB gain).
(Default may be changed to positive gain values on the Compass Preferences tab.)
•
The Delay widget allows the user to add a delay (0–2000 ms) in various units to an output channel signal.
•
The Polarity button allows the user to change the polarity of each output channel from Normal (Pin 2 positive relative to
Pin 3) to Reversed Polarity (Pin 3 positive relative to Pin 2).
•
Clicking the Mute button prevents any signal from being sent to the output of the channel.
•
Clicking the Select button causes this channel to be linked to other output channels that are also selected. Changes
made to one selected channel will be made to all other selected channels of the same type (input or output) in a
processor. These changes are relative by default. If channel 1 delay is 0 ms and channel 2 delay is 10 ms, when they are
linked and channel 1 delay is changed to 5 ms, channel 2 delay will be 15 ms. Hold ALT while pressing ENTER for
absolute values. To change default preference, change settings on this tab: Compass > GALAXY Preferences > Select,
Isolate and Linking. Depending on the Global Linking Preferences, channels on other devices may be affected as well.
Use Link Groups to quickly select or deselect multiple channels. Selected channels have a green background.
•
Use the Isolate button to temporarily isolate a channel from other channels to which it is linked. Isolating a channel will
change its background color to amber.
•
Use the Link Groups button to edit multiple channels simultaneously. The Link Groups tab is also accessible from this
pull-down menu. The Link Group to which a channel belongs is indicated by the number next to “LG.” Link Group index
buttons are blue when enabled, yellow when bypassed, and gray when not in use. Channels in active link groups may
have a blue background, depending on the Link Groups and Selects mode.
•
The LMBC Bypass button is a shortcut to the Low-Mid Beam Control tab (see Appendix D,“Low-Mid Beam Control,” on
page 67).
•
The Parametric EQ Bypass button allows the user to bypass Parametric EQ for an output channel without affecting the
individual Parametric Band Bypass settings.
•
The U-Shaping Bypass button allows the user to bypass the U-Shaping EQ filter on a GALAXY processor output
channel.
•
The EQ Bypass button allows the user to bypass all output Equalization filters while leaving filter-specific EQ bypass
settings alone. Product Integration and Atmospheric Correction settings are not bypassed with this control.
•
The High Pass Filter widget allows the user to select a high-pass filter for the output channels from nine different options.
•
The Low Pass Filter widget allows the user to select a low-pass filter for the output channels from eight different options.
•
The Atmospheric Correction widget allows the user to apply equalization to the higher frequencies of a signal that might
be affected by the natural environment. There are also widgets to enter the distance between the loudspeakers and the
listening area. The attenuation of higher frequencies in the air varies with temperature, humidity, and altitude. There are
Global Environment settings that allow a user to adjust for a particular natural environment (see “Environment” on
page 36 and “Atmospheric Correction” on page 71).
•
The Product Integration button allows a user to turn on Product Integration for a particular channel (see “Product
Integration” on page 63).
