MODEL 209
TALENT CONSOLE
microphone the five green LEDs should light. The
two orange LEDs should light on signal peaks; the
red LED will only light when the signal is near to or
actually “clipping.” If the meter does not light in this
manner, it’s recommended that the gain of the pre-
amplifier be adjusted as required.
As a “reality check,” it’s recommended that a level
meter associated with a device that’s digitally con
-
nected to the Model 209’s Dante Main transmitter
(output) channel be observed. This will be an excel-
lent means of checking the actual signal level within
the signal “chain.” If necessary, adjust the gain of the
Model 209’s microphone preamplifier to achieve the
desired result.
Headphone Output – Routing
Choices are Dual-Channel Stereo, Dual-Channel
Mono, and Single-Channel Mono.
STcontroller allows selection from among three
headphone output modes. Each mode is distinct and
careful selection will help optimize the Model 209’s
operation for a range of applications.
Dual-Channel Stereo: The Dual-Channel Stereo
mode is provided for applications where two inde
-
pendent audio sources need to be independently
routed to the two headphone output channels. Dante
receiver (input) channel 1 will be routed to the left
headphone output channel and Dante receiver (input)
channel 2 will be routed to the right headphone output
channel. Note that in this mode the sidetone audio
signal, if enabled, will be routed to both the left and
right headphone output channels.
Dual-Channel Mono: The Dual-Channel Mono mode
can be useful in applications where the same audio
signals need to be provided to the user on both the left
and right headphone output channels. In this mode
Dante receiver (input) channel 1 and Dante receiver
(input) channel 2 are combined (mixed together
or “summed”) and routed to both the left and right
headphone output channels. Note that in this mode
the sidetone audio signal, if enabled, will be routed to
both the left and right headphone output channels.
Single-Channel Mono: The Single-Channel Mono
mode is specifically provided for applications where
a 2-conductor ¼-inch plug is being used with the con
-
nected headphones, headset, or a broadcast-style
earpiece. In this mode audio from Dante receiver
(input) channel 1 and Dante receiver (input) chan
-
nel 2 are combined (mixed or summed) to monaural
and routed to only the left channel of the headphone
output; no audio signal is routed to the right channel
of the headphone output. Note that in this mode the
sidetone audio signal, if enabled, will be routed to
only the left headphone output channel.
Headphone Output – Minimum Level
Choices are Full Mute and –40 dB.
Full Mute: A setting in STcontroller is used to config
-
ure the headphone output’s minimum level. When Full
Mute is selected moving the headphone level control
fully counterclockwise will cause the headphone out-
put to fully mute. Selecting the full mute mode may
be appropriate for applications where minimizing the
chance of audio “leakage” is important. This could oc-
cur when during an event the connected headphones
or headset is at times placed on a desk or tabletop.
This could result in unwanted audio leakage from
the ear cups.
–40 dB: In the –40 dB setting the minimum head
-
phone output level is approximately 40 dB below its
maximum; the headphone output channels will never
fully mute. This ensures that any audio signal present
on the Dante receiver (input) channels will always
be present on the headphone output, even if they
are at a very-low level. In many on-air broadcast or
streaming applications this would be the appropriate
setting, ensuring that a minimum amount of signal is
always present on the ‘phones. This minimal level can
make certain that talent cue (IFB) or other production
audio sources can always be heard, even faintly, by
a Model 209 user.
Headphone Output – Sidetone Mode
Choices are Main Active, Talkback Active, and Always
Active.
STcontroller allows selection from among three
sidetone modes. Sidetone is audio from the output
of the microphone preamplifier that is sent to the
headphone output channel or channels. It is mixed
(combined or summed) with audio that arrives by way
of the Model 209’s Dante receiver (input) channels.
Sidetone can be important, allowing the user to “hear”
themselves as appropriate for performance confirma-
