Model 5205
Mic/Line to Dante Interface
on the front panel will light in a test se-
quence. After the LEDs complete their test
sequence one LED associated with the
level meter for channel 1 and one LED as-
sociated with the level meter for channel 2
will briefly light to indicate the version num-
ber of the unit’s application firmware (em-
bedded software). (Understanding how to
“read” the application firmware number will
be discussed in detail later in this guide.)
Once the entire sequence has completed
and the Dante connection has been estab-
lished full operation will begin.
Ethernet, PoE, and Dante
Status LEDs
Four status LEDs are located below the
etherCON connector on the Model 5205’s
back panel. The PoE LED will light green
to indicate that Power-over-Ethernet (PoE)
power associated with the connected Eth-
ernet signal is providing operating power
for the Model 5205. The LINK/ACT LED
will light green whenever an active connec-
tion to a 100 Mb/s Ethernet network has
been established. It will flash in response
to Ethernet data packet activity. The SYS
and SYNC LEDs display the operating sta-
tus of the Dante interface and associated
network. The SYS LED will light red upon
Model 5205 power up to indicate that the
Dante interface is not ready. After a short
interval it will light green to indicate that it
is ready to pass data with another Dante
device. The SYNC LED will light red when
the Model 5205 is not synchronized with
a Dante network. It will light solid green
when the Model 5205 is synchronized with
a Dante network and an external clock
source (timing reference) is being received.
It will slowly flash green when the Model
5205 is part of a Dante network and is
serving as a clock master.
How to Identify a Specific
Model 5205
The Dante Controller software application
offers an identify command that can be
used to help locate a specific Model 5205.
When identify is selected for a specific unit
its meter LEDs will light in a unique pat-
tern. In addition, the SYS and SYNC LEDs,
located directly below the etherCON con-
nector on the back panel, will slowly flash
green. After a few seconds the LED iden
-
tification patterns will cease and normal
Model 5205 level meter and Dante status
LED operation will again take place.
Level Meters
Two 8-step LED meters display the level
of the two Dante transmitter (output) chan-
nels. The meter steps are calibrated in
dBFS which indicates the number of dB
below the maximum possible digital signal
level. The maximum level, 0 dBFS, is the
digital audio reference level equal to “full
scale.” Full scale refers to the maximum
level possible for a sine wave before “digi-
tal clipping.” In typical applications a signal
with a nominal (normal) level of –20 dBFS
would be desirable. The five meter steps
that have a threshold of –20 dBFS and
less light with the color green. The steps
that light at –15 and –10 dBFS are yellow
in color and indicate “hot” or above aver-
age signal levels. The top step lights red
in color when a signal level is –5 dBFS
or greater, indicating that a potentially
“clipped” (distorted due to excessive level)
signal is present.
Mic/Line Inputs
Two 3-pin female XLR connectors are
provided to interface analog audio signals
with the Model 5205’s mic/line inputs.
