Headphone Output Operating Modes
The user is provided with two rotary level
controls (“pots”) that are associated with
the stereo headphone output. Switches
SW3-4, SW3-5, and SW3-6 are used to
configure the way the controls function.
With just these three switches a wide
range of operating modes can be con-
figured. Carefully reviewing the capabili-
ties of the available functions may prove
worthwhile.
Dual-Channel or Stereo Mode
Switch SW3-4 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
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 left rotary control sets the overall
output level for both headphone channels.
The right rotary 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.
set to the normal mode, and level/level
mode is also selected, the left control ad-
justs 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 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 output, 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 set to reverse mode,
and the level/level mode is also selected,
the left control adjusts the headphone
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 is also se-
lected, turning the balance control in the
counterclockwise direction increases the
perceived level of the right channel output,
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.

Reverse Left/Right Mode
Switch SW3-5 is used to select whether
the rotary controls are in the normal or
reverse left/right mode of operation. When
