Vega’s C-2002
7.6 Line Tone/Local Screen
The Line setup menus allows for the parameters unique to each line to be setup on a per line basis. Parameters that
can be adjusted by pressing the LN1-LN2 keys from the top level menu include: Enable/Disabling of the line, Tone
or Local control, Cross Mute, Squelch, TX Monitor, AGC, TX Enabled, and Unselect Audio Forced. The LN1-
LN2 keys are active at all times in the menu; for example, to disable AGC on all lines, AGC could be selected on
LN1, setup, then LN2 could immediately be pressed from within the AGC menu, eliminating going back and then
back through the menus for each line.
7.6.1 Enable/Disable the Line
Disabling a line sets the line so that a user cannot select its audio. It would generally be desired to set a line to be
disabled if a physical line is not connected to the console. If the line is disabled from this menu, then the console
ignores the line select key.
PROG1 - Toggles the line from Enabled to Disabled.
PROG3 - Moves to the next menu.
PROG4 - returns to the Opening Menu Screen.
7.6.2 Tone or Local Control
This screen allows the technician to determine if a line is tone control or local control. If a line is tone control then
a tone burst is transmitted before voice is allowed to drive the line and a hold tone is sent out with the voice to
provide a positive key for the remote adapter. If a line is a local control line then the tone generator is not activated
and voice drives the line when the PTT button is pressed. The line number of the selected line appears in the top
line of the display. The example shows that line 2 has been selected. The text at the right side of the top line shows
which mode the line is programmed with.
PROG1 - Toggles the line from Tone to Local.
PROG3 - Moves to the next menu.
PROG4 - returns to the Opening Menu Screen.
7.6.3 Crossmute Setup
The crossmute function allows consoles located within the same room to mute the other consoles RX audio while
transmitting to prevent feedback. See Section 5 on how to connect this feature on the line cards. This feature can
be turned on and off on a per line basis. Disabling crossmute does not disable the input. If the crossmute pin is
connected, and the line is pulled low, the console will mute the line. The crossmute enable/disable function only
controls the ability of the console to output crossmute. Note: Intercom will not work on lines with crossmute
enabled.
PROG1 - Toggle the Cross Mute function ON and OFF.
PROG3 - Move to the next menu.
PROG4 - returns to the opening Menu Screen.
7.6.4 Squelch Setup
The Squelch function can be turned on a per line basis. It is tied to the level setup by the LAM function. If the
LAM LED is blinking, squelch will not be active. If the audio present on the line is below that required to generate
a LAM indication and squelch is enabled, no audio will be heard.
PROG1 - Toggle the Squelch function ON and OFF.
PROG3 - Move to the next menu.
PROG4 - returns to the opening Menu Screen.
7.6.5 TX Monitor Enable/Disable
The TX monitor allows the operator to listen to what is currently being transmitted. In a 4 wire mode, this allows
one console operator to monitor what is being said by another console operator. The other operator could be in the
same room or a greater distance away.
