• Hybrid: This mode is a combination of
push to talk and alternate action. If the
button is pressed and held, the talk-
back output will become active until
the button is released. If the button is
momentarily “tapped” the talkback out-
put will change state. Upon power
up the talkback output will be in its
muted state.
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
configuration the way the controls func-
tion. 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 (“lev-
el/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 ap-
plications where independent cue signals
are provided to the left- and right-head-
phone 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.
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 selected
to the normal mode, and level/level 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 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 left control adjusts the headphone out-
put’s right channel (output jack’s ring lead)
while the right control adjusts the left chan-
nel. When selected to the reverse mode,
and the level/balance is also selected, turn-
ing the balance control in the counterclock-
wise direction increases the perceived level
of the right channel, and vice versa.
