LINE: This switch position allows the MoniCough to take a ste -
reo monitoring signal and feed it to the left and right headphone 
outputs.
Use the INT/A control on the front panel to adjust the level of 
both channels of the stereo signal.

Operating the MoniCough
The MoniCough operation depends chie y on the settings made 
on the bottom panel of the unit.
Basically, the ON switch is used to turn the mic between live 
and muted. Whether the switch is latching or non - latching, and 
whether the unit is on - air or muted when turned on are deter-
mined by the switch settings. See the section on “Setting up the 
MoniCough” earlier in this manual for details.
When the TALK BACK key is pressed and the bottom panel  
TB SW FUNCTION switch is set to ON, talkback through the inter-
com system is enabled with the TALK BACK key. If the program 
output is not already muted, pressing the TALK BACK key mutes 
it. When this switch is OFF, talkback is always enabled (the 
TALK BACK key is disabled).
The mic volume is adjusted using the GAIN control (controlling 
the program and talkback gain together).
The side tone level is adjusted using the SIDE TONE control on 
the front panel (when it has been enabled using the bottom 
panel SIDE TONE switch).
The pager/communications feed levels are adjusted on the 
MoniCough as explained in the previous section, using the 
INT/A (and optionally the NON INT/ B) control(s), depending on 
the setting of the selector switch.
As a reminder, the switch positions are given again here:

About the fader model (KS4310)
The principal difference between the fader and switch models is 
that on the fader model the talk switch and the TALK BACK key 
are replaced by a single fader. Note that the illustration here 
shows the standard 1/4” headphone jack model.

B.T.
Pushing the fader up enables the microphone and lights the 
ON indicator, which therefore acts as an “on air” indicator. 
Since the concept of “latching” versus “non - latching” does not 
apply here, the different options available through the switches 
on the switch model’s bottom panel are not available on the 
fader model.
The TALK BACK key’s functionality is achieved by pulling 
the fader down (and muting the output) to a non - latching 
position where the B.T. Indicator lights (“back talk”). The 
TB SWITCH FUNCTION key on the bottom panel is used to enable 
or disable this function. When disabled, talkback is always ac -
tive, regardless of the fader position.

Note that the MONI /TB connector pinout varies, depending on 
the setting of the monitor switch.
In the table above, no asterisk by a pin descriptor means that 
the pin retains its function in all modes or that in the case of 
multiple functions for that pin, the LINE mode is selected. One 
asterisk (*) indicates the RTS setting. T wo asterisks (**) show 
that this assignment is valid in the CC - 2 mode, and three aster-
isks show the assignment is valid in CC -1 mode.
