level of audio inputs 3 and 4 is con-
trolled by rotary level control C3, located
on the right side of the front panel. The
sidetone function will not be active.
Headphone Minimum Level
Switch SW1-9 is used to configure the
headphone output’s minimum level.
In the –40 dB setting the minimum head-
phone output level is approximately 40 dB
rotary level control C1, located on the left
side of the front panel. The balance (rela-
tive level) of both these signals is con-
trolled by rotary level control C2, located
in the center of the front panel. Sidetone
audio is assigned to both the left and
right headphone output channels and its
level is controlled by rotary level control
C3, located on the right side of the front
panel. Audio inputs 3 and 4 are not used.
• SW1-7 Off (Down)/SW1-8 On (Up): Audio
input channel 1 is assigned to both the
left and right headphone output chan-
nels. The level of the signal being sent
to both channels is controlled by rotary
level control C1, located on the left side
of the front panel. Audio input channel
2 is assigned to both the left and right
headphone output channels. The level
of the signal being sent to both channels
is controlled by rotary level control C2,
located in the center of the front panel.
Audio input channel 3 is assigned to
the left headphone output channel and
audio input channel 4 is assigned to the
right headphone output channel. The
level of audio inputs 3 and 4 is controlled
by rotary level control C3, located on the
right side of the front panel. The sidetone
function will not be active.
• SW1-7 On (Up)/SW1-8 On (Up): Audio
input channel 1 is assigned to the left
headphone output channel and its level
is controlled by rotary level control C1,
located on the left side of the front panel.
Audio input channel 2 is assigned to the
right headphone output channel and its
level is controlled by rotary level control
C2, located in the center of the front
panel. Audio input channel 3 is assigned
to the left headphone output channel
and audio input channel 4 is assigned to
the right headphone output channel. The

below maximum. The headphone output
will never fully mute. This ensures that
any audio signal present on the assigned
audio input channels (1 and 2 or 1, 2, 3,
and 4) will always be present on the head-
phone output. In most on-air broadcast
applications this is the appropriate setting,
ensuring the some level of signal is always
present.
When full mute is selected moving any
level control to its fully counterclockwise
position will cause its associated chan-
nel to fully mute. If a rotary level control is
set to serve as a balance control, moving
it to either fully counterclockwise or fully
clockwise position will cause the associ-
ated signal to fully mute. Selecting the full
mute mode may be appropriate for ap-
plications where minimizing the chance of
audio “leakage” is important. This could
occur when the connected headset or
headphones are at times placed on a desk
or tabletop.
