providing realistic voice input and background noise levels, adjust the
gating level and attack/decay times to eliminate undesired input while
providing the best content quality.
NOTE:
Settings for gain, gating levels, attack time, and decay time will be
maintained in the event of power failure.
Operation
Operating Modes
The MD7x2 operates in either the system mode or the local mode. When operating in
the system mode, all switching functions are controlled by the control system.
Additionally, signal routing information can be viewed using the front panel controls
of the MD7x2. When operating in the local mode, all switching functions are
controlled by the buttons on the front panel.
Press the
SYS
button located on the front panel to select the system mode or press
the
LOCAL
button to select the local mode. The
SYS
LED will illuminate when the
MD7x2 is operating in the system mode. The
LOCAL
LED will flash when the
MD7x2 is in the local mode.
NOTE:
The local mode may not be available if the buttons on the front panel are
locked by the control system. The
LOCAL
LED will rapidly flash three times and
turn off to indicate that the local mode is not available when the front panel is
locked.
Viewing Signal Routes in the System Mode
When in the system mode (
SYS
LED is illuminated), pressing an input signal button
will display all of the outputs that are routed to it. Pressing an output signal button
will display the input signal that it is connected to as well as all of the other outputs
that are receiving the same input signal.
The
AUDIO BREAK
LED will illuminate if there is any difference between the
audio and video route for any signal. The
A
and
V
LEDs indicate which portion of a
signal is displayed. Press
A
or
V
to select the portion to display.
NOTE:
The
AUDIO BREAK
button has no function when the MD7x2 is operating
in the system mode.
Switching Signals in the Local Mode
Signals coming in to the MD7x2 can be switched to individual or multiple output
locations. Additionally, the audio and video portions of an input signal can be
switched simultaneously or separately.
