Model 5204
Dual Line Input to Dante Interface
Line Inputs A & B Combine
It’s important to highlight that the Model
5204’s two 2-channel line inputs (A and B)
combine in the analog domain. In effect
the Model 5204 is a dual-input 2-channel
(stereo) mixer and Dante converter. A sig-
nal present on channel 1 (left) of line input
A and a signal present on channel 1 of line
input B will combine (mix together or sum)
after (“post”) the two level controls. This
combined signal is routed to the analog-
to-digital converter circuitry and on to the
Dante transmitter (output) for channel 1.
A signal present on channel 2 (right) of line
input A and a signal present on channel 2
of line input B will combine (mix together
or sum) after (“post”) the two level controls.
This combined signal is routed to the ana-
log-to-digital converter circuitry and on to
the Dante transmitter (output) for channel
2. But note that no monaural version of the
input signals is created.
USB Dedicated Charging Port
There are no special instructions when
using the dedicated charging port. Simply
connect the desired device and the func-
tion will typically automatically start. The
only limitations will be with the port’s 5
volt, 1 ampere (5 watt) maximum power
supply capability. A connected device that
requires more energy for operation may
not enumerate (handshake or negotiate)
successfully. No damage will occur in this
case.
There are no LEDs or performance indica-
tors or configuration settings associated
with the dedicated charging port. It’s really
just a “plug-in and go” feature.
Technical Notes
IP Address Assignment
By default the Model 5204’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-
local 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.
Using the Dante Controller software ap-
plication the Model 5204’s IP address and
related network parameters can be set for
a fixed (“static”) configuration. While this is
more involved than letting DHCP or link-
local “do their thing,” if fixed addressing is
necessary then that capability is available.
But in this case it’s highly recommended
that each unit be physically marked, e.g.,
directly using a permanent marker or
“console tape,” with its specific IP address.
If knowledge of a Model 5204’s IP address
has been misplaced there is no reset but
-
ton or other method to restore the unit to a
default IP setting.
In the unfortunate event that a device’s IP
address is “lost,” the Address Resolution
Protocol (ARP) networking command can
