Sidetone
Switch SW5 allows the sidetone function
to be enabled or disable as desired.
Selecting the on or off mode for sidetone
will depend on the needs of the applica-
tion. If a “full mix” is being provided to the
Model 380 then locally provided sidetone
won’t need to be provided. The user will
hear themselves by way of the audio sig-
nals being routed to the Dante input audio
channels. But if a “mix-minus” is being
supplied to the Model 380 then having
sidetone enabled will be important as a
user confidence monitor.
channels (Dante transmitter channels) and
two audio input channels (Dante receiver
channels) should have been routed to
the receiver and transmitter channels
on associated equipment. The Model
380’s configuration switches should have
been set to meet the needs of the specific
application.
Initial Operation
The Model 380 will start to function as
soon as a Power-over-Ethernet (PoE)
power source is connected. However,
it may take 20 to 30 seconds for full
operation to commence. Upon initial
power up the three status LEDs located
on the bottom panel below the RJ45 jack
will begin to light as network and Dante
connections are established. The green
and orange LED backlights within the
talkback pushbutton switch will light in a
quick test sequence to indicate that the
main operating firmware (embedded soft-
ware) has started. Once the sequence has
completed and the Dante connection has
been established full operation will begin.
Ethernet and Dante Status
LEDs
Three status LEDs are located below the
etherCON RJ45 connector on the Model
380’s bottom panel. The LINK ACT LED
will light green whenever an active con-
nection to a 100 Mb/s Ethernet network
has been established. It will flash in re-
sponse to Ethernet data packet activity.
The SYS and SYNC LEDs display the
operating status of the Dante interface
and associated network. The SYS LED
will light red upon Model 380 power up
to indicate that the Dante interface is not
ready. After a short interval it will light
Operation
At this point everything should be ready
and Model 380 operation can commence.
An Ethernet connection with Power-over-
Ethernet (PoE) capability should have
been made. Alternately, a midspan power
injector, in “series” with the Ethernet con-
nection, should have been put into place.
A microphone and headphones or earbud
should have been connected. Alternately,
a broadcast-style headset should be
connected. If desired, a connection to
the microphone output should have
been made.
The Model 380’s Dante configuration
settings should have been selected using
the Dante Controller software application.
In this way the unit’s two audio output
