one audio source to be routed to the
Model 391 while others may utilize both.
The Model 391 supports an audio sample
rate of 48 kHz with no pull-up/pull-down
values available. While technically the
Model 391 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 391 has a default Dante device
name of ST-M391 along with a unique suf-
fix. The suffix identifies the specific Model
391 that is being configured. The suffix’s
actual alpha and/or numeric characters
relate to the MAC address of the unit’s
Ultimo integrated circuit. The two Dante
receiver (Rx) audio input channels have
default names of Ch1 and Ch2. Using
Dante Controller the default device name
and channel labels can be revised as
appropriate for the specific application.
Model 391
Configuration
The STcontroller software application is
used to configure the way in which the
Model 391 functions. No DIP switch settings
or other local actions are used to configure
the unit. This makes it imperative that
STcontroller be available for convenient
use in a personal computer that’s connect-
ed to the related LAN.
STcontroller is available free of charge
on the Studio Technologies website
(www.studio-tech.com/stcontroller) and
is compatible with personal computers run-
ning Windows operating systems that are
version 7 and later. STcontroller versions
1.07.00 and later will fully support the
Model 391. If required, download and install
STcontroller onto a designated personal
computer. This personal computer must be
on the same local area network (LAN) and
subnet as the Model 391 unit or units that
are to be configured.
STcontroller allows observation and selec-
tion of whether Mode 1 or Mode 2 is active.
Another selection allows access to Mode
2 to be disabled. In addition, the following
operating parameters can be independently
configured for Mode 1 and Mode 2:
• Call Source
• Line Out
• Visual Alert Status, Minimum On Time,
Intensity, Action, and Color
• Audio Alert Status, Action, and On Delay
Operating mode and configuration changes
will immediately be reflected in the unit’s
operation. No Model 391 “reboot” or
other action is required. Each time a
configuration change is made the Model
391’s visual indicator will momentarily flash
yellow to indicate that a command from
STcontroller has been received.
Using STcontroller
Immediately after starting STcontroller the
application will locate the devices that it
can control. The Model 391 unit or units will
appear in the device list. Use the identify
command to allow easy recognition of a
specific Model 391 unit. Upon receiving an
identify command a Model 391 will momen-
tarily flash its visual indicator with a green
color. Double-clicking on a device name will
cause the associated configuration menu
to appear. Review the current configuration
and make changes as required.
