Model 5202
Dante to Phones and Line Output Interface
Model 5202 level meter and Dante status
LED operation will again take place.
Level Meters
Two 7-step LED meters will display the
level of the two Dante audio receiver (input)
channels. 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
level of –20 dBFS would be the nominal
(normal average) value. The five meter
steps that have a threshold of –20 dBFS
and less light with the color green. The step
that lights at –15 dBFS and greater is yel-
low in color and indicates a “hot” or above
average signal level. 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.
Headphone Output
Dante input channel 1 is routed to the left
headphone output channel. This signal is
connected to the tip connection on both
the 3.5 mm and ¼-inch headphone output
jacks. Dante input channel 2 is routed to
the right headphone output channel which
is associated with the ring connection on
the output jacks. The push-in/push-out
headphone level control adjusts the level of
both the left and right channels of the head-
phone outputs. In the fully counterclockwise
position the output level is essentially off.
Care must be taken when adjusting the
headphone output level control. The output
circuitry is capable of driving headphones,
headsets, or earbuds to damaging levels.
Hearing damage is a real possibility and
caution must be exercised.
Line Outputs
Dante input channel 1 is routed to line
output channel 1. Dante input channel 2
is routed to line output channel 2. The
associated push-in/push-out rotary control
adjusts the level of both line output chan
-
nels. In its fully counterclockwise position
the output level of the two channels are
essentially off. In its fully clockwise position
the output levels will be approximately
+4 dBu with a Dante input signal that has
a level of –20 dBFS.
Technical Notes
IP Address Assignment
By default the Model 5202’s Ethernet
interface will attempt to obtain an IP ad-
dress and associated settings using DHCP
(Dynamic Host Configuration Protocol).
If a DHCP server is not detected an IP
address will be assigned using the link-lo-
cal protocol. This protocol is known in the
Microsoft® world as Automatic Private IP
Addressing (APIPA). It is also sometimes
referred to as auto-IP (PIPPA). Link-local
will assign an IP address in the IPv4 range
of 169.254.0.1 to 169.254.255.254. In this
way multiple Dante-enabled devices can
be connected together and automatically
function, whether or not a DHCP server
is active on the LAN. Even two Dante-en-
abled devices that are directly intercon-
nected using an RJ45 patch cord will
correctly acquire IP addresses and be able
to communicate and transport audio.
