Headphone Output Operating
Modes
The user is provided with three rotary level
controls (“pots”) that are associated with
the headphone output. Switches SW4-1,
SW4-2, and SW4-3 are used to configure
the way two of the controls, the one locat-
ed on the far left and the one located in
the center, function. (These settings don’t
impact operation of the sidetone level con-
trol which is located on the far right.) With
just these three switches a wide range of
operating modes can be configured. Care-
fully reviewing the capabilities of the avail-
able functions may prove worthwhile.
Dual-Channel or Stereo Mode
Switch SW4-1 is used to select whether
the control located on the far left and
the control located in the center provide
a dual-channel (“level/level”) or stereo
(“level/balance”) mode of operation. In the
level/level mode these two controls operate
independently, each controlling the level
of one of the headphone output channels.
This mode is generally used for on-air
broadcast applications where independent
cue signals are provided to the left- and
right-headphone channels. In the level/
balance mode the control on the far left
sets the overall output level for both head-
phone channels. The center control is used
to adjust the balance (the relative levels)
of the left and right channels. This mode is
generally best suited for applications where
a stereo cue source is being provided.
Reverse Left/Right Mode
Switch SW4-2 is used to select whether two
of the rotary controls are in the normal or
reverse left/right mode of operation. When
selected to the normal mode, and level/level
mode is also selected, the control on the far
left adjusts the level of headphone output’s
left channel. (This is the signal that appears
on the tip lead of the ¼-inch 3-conductor
jack.) The center control adjusts the level
of the right channel. When selected to the
normal mode, and the level/balance mode
is also selected, turning the balance control
in the counterclockwise direction increases
the perceived level of the left channel, and
vice versa.
As you may have already guessed, when
selecting the reverse left/right mode of op-
eration everything is reversed! To be more
specific, when selected for reverse mode,
and the level/level mode is also selected,
the control on the far left adjusts the head-
phone output’s right channel (output jack’s
ring lead) while the control in the center ad-
justs the left channel. When selected to the
reverse mode, and the level/balance mode
is also selected, turning the balance control
in the counterclockwise direction increases
the perceived level of the right channel, and
vice versa.
The reverse mode is provided specifically
for cases where a headset’s left and right
earpieces are placed on a user’s head in
a reverse orientation. This ensures that the
user is provided with a consistent and easy-
to-use set of headphone level controls.
