Model 5422A
DANTE INTERCOM AUDIO ENGINE
routed to the listen input on that specific intercom
device. So, for example, if Dante transmitter (output)
channel one of a Studio Technologies’ Model 371A
Dante Beltpack is routed to input 02 of a Model 5422A
PL group, then that group’s output 02 must be routed to
the receiver (input) of channel one of the Model 370A.
Output 02 is the mix-minus signal that channel one of
this specific Model 371A requires for correct operation;
no other device should utilize output 02.
Restated for clarity, for correct PL operation to take
place one, and only one, pair of channels (one “talk”
and one “listen”) from an intercom user device must be
routed (Dante subscribed) to one pair of channels (one
“listen” and one “talk”) on a Model 5422A PL group.
These routes must be made to associated channel
pairs on both the Dante beltpack or intercom station
devices and Model 5422A PL channels.
Party-line (PL) channel routing (Dante subscribing) is
the main area of confusion when users first encounter
a Model 5422A. But after some study and experimen-
tation the process should become clear. It’s important
to remember that when associating an intercom device
to a PL channel on a Model 5422A PL group always
involves routing (Dante subscribing) two channels. Two
routes (Dante subscriptions) will always be made to
add an intercom channel to a Model 5422A PL group.
A Dante transmitter (output) channel that has “talk”
audio from the intercom device needs to be routed
to the input on a PL group. The associated Dante
transmitter (output) channel on the same PL group
(the specific mix-minus output) needs to be routed to
the input on the intercom device. Without routing both
channels, PL functionality will not be achieved.
Another suggestion is that unless one is experienced
with how the Model 5422A creates PL, start by creat-
ing a small implementation. Don’t try to route (Dante
subscribe) a large number of channels or user devices
at one time. The complexity will make it very difficult
to achieve the desired result. Begin by creating the
world’s smallest PL intercom. Link one channel be-
tween two user devices. Try the sidetone function on
the two user devices. Turn off sidetone and ensure
that each user device is getting a “mix-minus” — each
should hear the other but not itself. Then set sidetone
to the device level. Get that functioning correctly and
you’ll understand the basics. Only then move on to
adding additional user devices. Spending one or two
hours experimenting with these topics will help to fully
understanding what’s going on. From there you’ll be
ready to implement whatever your final application
requires.
