Headphone Output Operating Modes
The user is provided with two 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 the controls function. With just
these three switches a wide range of oper-
ating modes can be configured. Carefully
reviewing the capabilities of the available
functions may prove worthwhile.
Dual-Channel or Stereo Mode
Switch SW4-1 is used to select whether
the controls provide a dual-channel (“level/
level”) or stereo (“level/balance”) mode
of operation. In the level/level mode the
two controls operate independently, each
controlling the level of one of the head-
phone output channels. This mode is
generally used for on-air broadcast appli-
cations where independent cue signals are
provided to the left- and right-headphone
channels. In the level/balance mode the left
control sets the overall output level for both
headphone channels. The right control
is used to adjust the balance (the relative
levels) of the left and right channels. This
mode is generally best suited for applica-
tions where a stereo cue source is being
provided.
mode is also selected, the left control
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 right control adjusts the level of
the right channel. When set 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
operation everything is reversed! To be
more specific, when selected for reverse
mode, and the level/level mode is also
selected, the left control adjusts the head-
phone output’s right channel (output jack’s
ring lead) while the right control adjusts 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
ear pieces 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.

Switch SW4-2 is used to select whether
the rotary controls are in the normal or
reverse left/right mode of operation. When
