Stereo Line Input – Gain
Choices are –3 dB, 0 dB, 3 dB, 6 dB, 9 dB,
and 12 dB.
The gain of the circuitry associated with
the stereo line input can be selected from
among six choices. Two bi-color LEDs,
located adjacent to the stereo line input’s
3.5 mm connector, can serve as a guide
when selecting the gain value. The LEDs
serve in a signal present and peak role, light-
ing green for signals that are in the normal
audio range and red when they approach or
reach audio “clipping.”
The first step to achieving optimal audio
performance is to confirm and, if required,
revise the level of the source. This will typi-
cally be the unbalanced stereo analog audio
output of a personal computer. A software
configuration setting associated with the
personal computer’s operating system should
allow adjustment of the output level, typi-
cally over a range of 0 (mute) to 100 (full
level). While there is no standard for what
these settings represent, selecting 100 can
be a good starting point. Tests that Studio
Technologies performed on multiple personal
computers never found that a full level setting
had resulted in audio degradation (“clipping”).
However, if issues do arise revise the output
level downward, first trying 90, then 80, then
70, etcetera, until good audio performance is
obtained.
Once the source level has been established
the stereo line input value on STcontroller
can be selected. Use the signal present/peak
(SIG/PK) LEDs on the Model 207 as a ref-
erence when adjusting the gain value. The
LEDs, one for each input channel, should
light green when signals in an acceptable
range are present. The LEDs should never
light red as this indicates imminent or active
distortion of the audio signal.
Headphone Output – Routing
Choices are Dual-Channel Stereo, Dual-
Channel Mono, and Single-Channel Mono.
STcontroller allows selection from among
three headphone output routing modes. Each
mode is distinct and careful selection will help
optimize the Model 207’s operation.
Dual-Channel Stereo
The Dual-Channel Stereo mode is provided
for applications where two independent audio
sources need to be routed to the two head-
phone output channels. Dante audio input
channel 1 will be routed to the left headphone
output channel and Dante audio input chan-
nel 2 will be routed to the right headphone
output channel. Note that in this mode the
sidetone audio signal 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 audio inputs 1 and 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 will be routed to both
the left and right headphone output channels.
Single-Channel Mono
The Single-Channel Mono mode is specifi-
cally provided for applications where a
2-conductor ¼-inch plug is being used with
the connected headphones, headset, or a
broadcast-style earpiece. In this mode Dante
audio inputs 1 and 2 are combined to monau-
ral 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 sig-
nal will be routed to only the left headphone
output channel.
