balance of audio input Ch 1 and audio
input channel 2. The level of the sidetone
audio will follow the Fixed Sidetone Level
configuration and will be sent to the left
headphone output channel.
• In the Ch 1 & 2 Level / Sidetone Level
mode the control on the left, labeled A,
adjusts the level of both the Ch 1 and
Ch 2 input audio signals as they are sent
to the left headphone output channel. The
control on the right, labeled B, adjusts the
level of the sidetone audio as it is being
sent to the left headphone output chan-

Sidetone Function Activity
The Model 381’s sidetone function is used
to send post-compressor microphone audio
to the headphone output as a user confir-
mation signal. When sidetone audio will be
actively sent to the headphone output will
depend on the configuration of the Head-
phone Output – Sidetone Mode in the
STcontroller application. The Sidetone
Mode can be configured such that sidetone
audio will be active only when the main
output is active, is active only when the
talkback output is active, or is active at all
times.
Whether sidetone audio will be sent to the
left and right headphone output channels or
only the left headphone output channel will
depend on the configuration of the Head-
phone Output – Routing configuration in
STcontroller. As expected, when the Head-
phone Output – Routing mode is configured
for Dual-Channel Stereo or Dual-Channel
Mono sidetone audio will be sent to both the
left and right headphone output channels.
When configured for Single-Channel Mono
sidetone audio will be sent only to the left
headphone output channel.
• In the Ch 1 & 2 Level / Balance mode the
control on the left, labeled A, adjusts the
level of both the Ch 1 and Ch 2 input audio
signals as they are sent to both the left and
right headphone output channels. The con-
trol on the right, labeled B, will adjust the
level balance of audio input Ch 1 and audio
input channel 2. The level of the sidetone
audio will follow the Fixed Sidetone Level
configuration and will be sent to both the
left and right headphone output channels.
• In the Ch 1 & 2 Level / Sidetone Level
mode the control on the left, labeled A,
adjusts the level of both the Ch 1 and
Ch 2 input audio signals as they are sent
to both the left and right headphone output
channels. The control on the right, labeled
B, adjusts the level of the sidetone audio
as it is being sent to both the left and right
channels of the headphone output. In this
mode the Fixed Sidetone Level configura-
tion will be ignored.
When Headphone Output – Routing is
configured to the Single-Channel Mono
mode:
• In the
Ch 1 Level / Ch 2 Level mode the
control on the left, labeled A, is used to
adjust the level of the channel 1 input
audio signal as it is being sent to the left
headphone output channel. The control
on the right, labeled B, controls the level
of the channel 2 input audio signal as it is
sent to the left headphone output channel.
Sidetone audio, whose level will follow the
Fixed Sidetone Level configuration, will be
sent to the left headphone output channel.
• In the Ch 1 & 2 Level / Balance mode the
control on the left, labeled A, adjusts the
level of both the Ch 1 and Ch 2 input audio
