Model 391 User Guide Issue 2, December 2018

Active Mode
Choices are: Mode 1 and Mode 2; also
can disable access to Mode 2
The active mode section of the Model 391
configuration screen within STcontroller
will display the mode that is currently ac-
tive. The choices are Mode 1 and Mode
2 with Mode 1 as the default. The active
mode can be changed by clicking on the
desired radio button. If the pushbutton
on the Model 391’s front panel is used
to change the active mode (press and
momentarily hold the button to make a
change) the status will be updated on the
STcontroller screen.
There may be applications where only one
active mode is desired. In this case simply
enable the check box for Disable Mode 2.
When selected, this will force the unit to
operate in Mode 1 only. The configuration
settings for Mode 2 will not be disturbed,
remaining for future use if desired. These
settings can be changed as designed
although they won’t be utilized.
Call Source
Choices are: Channel 1, Channel 2, and
Channel 1 & 2
A call signal (18-23 kHz nominal tone con-
tained within an audio channel) is used
by the Model 391 to activate the call func-
tions. These call functions, depending on
the configuration, can consist of the visual
indicator, audio sounder, and line output.
The Call Source configuration allows se
-
lection of which audio input (Dante receiv-
er channel) or audio inputs (Dante receiver
channels) will be designated to supply the
call signal(s). The default configuration for
both Mode 1 and Mode 2 is Channel 1.
Line Out
Choices are: Off, On When Call Active,
Always On–Ch 1, and Always On–Ch 2
This setting allows the operation of the
line-level analog output to be configured.
If On When Call Active is selected audio
from the designed Call Source Dante re-
ceiver channel will be present on the
line output whenever a call is detected.
If the call function is not active then no
audio will be present on the line output. If
either of the Always On choices is selected
any audio present on the specified Dante
receiver channel will be sent to the line
output. These two always-on configuration
choices allow the line output to serve as a
general-purpose Dante-to-analog output
converter. The default configuration for
both Mode 1 and Mode 2 is On When
Call Active.
Visual Alert
To provide a visual indication that a call
signal is active a set of five red/green/blue
(RGB) LEDs can project a full range of
colors into a futuristic polycarbonate lens
assembly. Five configuration parameters
allow the action of the visual indicator
assembly to be optimized for the desired
applications.
Status
Choices are: Off, On When Call Active,
and Always On
The Status configuration allows the over-
all operation of the visual indicator to be
selected. When selected for Off the visual
indicator will never light. When selected
for On When Call Active the visual indica-
tor will be enabled whenever a call signal
is received. When selected for Always On
the visual indicator will always be active.
