Connecting Power
The Model 5401A requires a source of AC
mains or nominal 12 volts DC for operation.
Either source can be connected with the
same result. Both can also be simultane-
ously connected if a redundant (backup)
power scheme is desired.
Connecting AC Mains Power
The Model 5401A can operate directly
from AC mains power of 100 to 240 volts,
50/60 Hz, 5 watts maximum. As a “universal
mains input” device there are no switches
to set or jumpers to install. A 3-pin IEC
320 C14 inlet connector on the back panel
mates with a detachable mains cord set.
All units are supplied from the factory
with an AC mains cord that has a North-
American (NEMA 5-15L) standard plug on
one end and an IEC 320 C13 connector
on the other end. Units intended for use in
other destinations require that an appropri-
ate mains cord be obtained. The wire colors
in the mains cord should conform to the
internationally recognized color code and
be terminated accordingly:
Connection Wire Color
Neutral (N) Light Blue
Line (L) Brown
Earth/Ground (E) Green/Yellow
Because the Model 5401A does not contain
a power on/off switch it will begin operation
as soon as AC mains power is connected.
Safety Warning: The Model 5401A does
not contain an AC mains disconnect
switch. As such, the AC mains cord plug
serves as the disconnection device.
Safety considerations require that the
plug and associated inlet be easily ac-
cessible to allow rapid disconnection
of AC mains power should it prove
necessary.
Connecting DC Power
The Model 5401A can also operate from
a source of 10 to 18 volts DC. The current
required from a 12 volts DC source is 0.5
ampere (500 milliamperes) maximum. A
4-pin male XLR connector, located on the
unit’s back panel, is used to connect the
source of DC. Prepare a mating connec-
tor (female) so that pin 1 is DC– and pin
4 is DC+. Pins 2 and 3 are not used and
should remain unconnected. This connector
type and pinout have become a broadcast
DC power standard and should be familiar
to many technical personnel. Because the
Model 5401A contains no power on/off switch
it will begin operation as soon as a DC power
source is connected.
As previously mentioned, both an AC mains
source and a DC source can be connected
at the same time. If this is the implementation
then the AC mains source will always power
the Model 5401A with the DC source serving
as a “hot standby.” Only if the AC source fails
will the unit draw power from the DC source.
This will occur automatically with no interrup-
tion of Model 5401A operation. In this
“standby” mode (when an AC mains source
is connected) the Model 5401A draws less
than 110 microamperes (uA) from a 12 volts
DC input.
Dante Configuration
For audio and timing to correctly pass from
the Model 5401A requires that several Dante-
related parameters be configured. These
configuration settings are stored in non-
volatile memory within the Model 5401A’s
Dante network interface circuitry. Configu-
ration will typically be done with the Dante
Controller software application, available for
download free of charge at audinate.com.
Refer to Appendix C of the list of the Model
5401A’s Dante Controller default configura-
tion. Versions of Dante Controller are avail-
able to support several operating systems.
