MODEL 204
ANNOUNCER’S CONSOLE
The Model 204 uses the Ultimo 4-input/
4-output integrated circuit to implement
the Dante functionality. The Model 204
can also be configured to meet the re-
quirements of the AES67 standard. This
requires a setting to be enabled within the
Device Info section of the Dante Controller
application.
The two Dante transmitter (Tx) channels
associated with the Model 204’s Dante in-
terface must be assigned to the desired re-
ceiver channels on associated equipment.
This achieves routing the Model 204’s two
output audio channels to the device (or
devices) that will be “listening” to them.
Within Dante Controller a “subscription” is
the term used for routing a transmitter flow
(a group of output channels) to a receiver
flow (a group of input channels). The num-
ber of transmitter flows associated with an
Ultimo integrated circuit is limited to two.
These can either be unicast, multicast, or a
combination of the two. If the Model 204’s
transmitter channels need to be routed to
more than two flows it’s possible that an
intermediary device with enhanced flow
capability, such as the Studio Technologies
Model 5422 Dante Intercom Audio Engine,
can be used to “repeat” the signals.
The desired audio sources need to be
routed to the receiver (Rx) channels as-
sociated with the Model 204’s Dante audio
inputs. The unit provides four audio input
channels. The number utilized will de-
pend on the specific application. Following
the unit’s headphone source and routing
configuration selection these audio signals
will be sent to the Model 204’s 2-channel
headphone output.
The Model 204 supports audio sample
rates of 44.1 and 48 kHz with no pull-up/
pull-down values available. In most cases
it’s anticipated that the default rate of 48
KHz will be appropriate. While technically
the Model 204 can serve as a clock master
for a Dante network (as can all Dante-
enabled devices) in virtually all cases the
unit will be configured to receive “sync”
from another device.
The Model 204 has a default Dante device
name of ST-M204 along with a unique suf-
fix. The suffix identifies the specific Model
204 that is being configured. The suffix’s
actual alpha and/or numeric characters
relate to the MAC address of the unit’s Ulti-
mo integrated circuit. The two Dante trans-
mitter (Tx) audio output channels have
default names of Main and Talkback. The
four Dante receiver (Rx) audio input chan-
nels have default names of Headphone
Ch1, Headphone Ch2, Headphone Ch3,
and Headphone Ch4. Using Dante Con-
troller the default device name and chan-
nel names can be revised as appropriate
for the specific application.
Model 204 Configuration
The STcontroller software application is
used to configure the way in which the
Model 204 functions. No DIP switch set-
tings or other local actions are used to
configure the unit. This makes it imperative
that STcontroller be available for conve-
nient use in a personal computer that’s
connected to the related LAN.
The configurable functions include:
• P48 phantom power on/off status
• Microphone input gain
• Headphone audio sources and routing
• Headphone gain range and minimum
level
• Sidetone
