Upgrade section for the procedure.
TALLY Output Port
Sends Red, and Green tally signals to each channel.
Red indicates On-Air, and Green indicates next camera source. Tally
output port can connect other Datavideo peripheral devices such as
ITC-100, ITC-200, AM-100 or other monitor models, allowing the
peripheral device to communicate with the SE-650 or send tally
signal to be displayed on the monitor.

States
MIC 1(L) and MIC 2(R) are respectively
connected to left and right channels.
When MIC 1 is connected to the left
channel and MIC 2 is not connected to
the right channel, the right channel
switch will replicate MIC 1 signal onto
the right channel thus both channels are
MIC 1 input signals.
When no MIC signal is connected to the
left channel and only MIC 2 is connected
to the right channel, MIC 2 signal will
not be replicated onto the left channel
which will thus be grounded.
When no MIC is connected to the two
channels, the left channel switch will
ground the left channel to prevent noise
from being generated.
