Thank you for using the Kamesan MoniCough unit. This pro -
vides you with an easy way of muting announcers’ microphone 
input, and enabling talkback to and from the producer’s station. 
Program monitoring following a number of different industr y 
standards is also available, as is a sideband facility.
Although the MoniCough is housed in a low- pro le,  attractive 
case, and has been designed to be simple to operate, there 
are a number of “hidden” features that add to its versatility. 
We therefore recommend that you read the manual carefully 
in order to discover the capabilities of the MoniCough so that 
you can set it up to meet the needs of your production environ -
ment.
NOTE: There are two models of the MoniCough unit. One, as 
described here, uses push-buttons for muting and talkback, and 
another model which uses a fader for the same purpose. A brief 
description of the fader model is provided in this manual for 
reference.
There are also other variants of the MoniCough. There is a 
choice of headphone connection, whereby either a stereo 1/4” 
jack socket is provided (standard con guration), or a 7- pin XLR 
input may be provided as an option, allowing the connection 
of a balanced headset microphone along with the stereo head -
set.
As well as the basic power connection, the connections to the 
MoniCough can be summarized as:
 Microphone input
 Headphone output
  Output to main program mixer
  Output to producer talkback
  Input from producer talkback and intercom system

Power
Connect a power supply providing at least 12VDC to the Moni -
Cough. Suitable power supplies are available from Kamesan. 
See the Kamesan Web site or consult your Kamesan dealer 
for details. Third party power supplies may be used, provided 
they meet the speci cations provided in this manual. Use of 
any other power supply may damage the MoniCough and con -
nected equipment. If in doubt, always check and double - check 
the speci cations.
Battery operation
Alternatively, you may choose to use four A A batteries. Follow 
the usual precautions when using batteries:
Always change all batteries together. Do not mix old and 
new batteries.
Note the polarity of the batteries as marked in the battery 
compartment when inserting batteries.
Do not mix different types of battery (for example, alkaline 
and NiCad).

A quick look at the MoniCough
The illustrations below give you a brief guide to the Moni -
Cough’s controls and features.
Note this these drawings show the switch model,  tted with the 
optional XLR -7 connector, which is replaced by a 1/4 - inch ste -
reo jack in the standard model. The bottom panel of the Moni -
Cough is described and illustrated separately as is the fader 
model.

Connections
Microphone
Either:
connect a microphone to the INPUT XLR connector on the rear 
panel. 
The wiring of this connector follows the 1= ground, 2=hot, 
3 = cold convention as do all 3 - pin XLR connectors on the Moni -
Cough.
or:
if you have the MoniCough model  tted with the optional front-
panel 7- pin XLR connector, ensure that your headset is wired in 
the way described here before making the connection.

3 MIC in (-)
4 Phones L (+)
5 Phones L (-)

IMPORTANT NOTE: The MoniCough can supply +48V 
phantom power to the microphone (XLR-3 connection only). Use 
the 
P48 switch on the rear panel to turn this on, only if you are 
connecting a condenser microphone which requires phantom 
power. If you have connected any other kind of microphone, do 
not turn this switch on.
Use the GAIN control to adjust the microphone signal level so 
that the SIGNAL indicator lights. A setting of between 30 and 
60 typically gives good results. The small SIG. (signal) indicator 
under the “MoniCough” logo lights yellow when a suf ciently 
high post- gain signal is detected.

Headphones:
For the stereo jack model, use either the 1/4” jack or 3.5 mm 
mini -jack stereo connections on the front panel.
Alternatively, if you have the MoniCough model  tted with the 
optional front- panel 7- pin XLR connector, connect your headset 
to the XLR connector. Check that the connections are as de -
scribed above before making the connection.
Line output
Use the balanced XLR connector to connect the output of the 
MoniCough to the mixer input, etc.
Monitor/talkback connection
To connect the MoniCough to the system - wide monitoring and 
talkback system, use the MONI /TB connector. The actual wiring 
of this connector differs, depending on the paging and talkback 
system in use, as selected by the monitor selection switch 
above this connector. Make sure that all cables are wired in ac -
cordance with your system before making this connection.
This connector carries both the talkback signal(s) from the 
booth announcer to the program controller and from the con -
trol intercom system to the booth announcer.
See the section on monitoring and talkback for full details of 
how to use the monitor and talkback connections.
Some sample setups (side tone)
The following illustrate some of the ways in which the Moni -
Cough can be used in different situations using the side tone fa -
cility or a feed from the main console, depending on the broad -
cast setup currently in use:
In the two examples below, one MoniCough unit is deployed 
with a separate headset and mic setup, and another with an in -
tegrated headset/mic. Functionally, these setups are identical, 
but the side tone feed is different.
In the  rst example, side tone is generated using a feed from 
the local sources, since there is a minimal time lag between the 
signal’s transmission and its reception.

In this second example below, the broadcast signal is trans -

also fed back in an internal loop to the MoniCough headset.

Setting up the MoniCough
The switch settings on the bottom panel allow you to customize 
the MoniCough for your particular working style.

See the illustration above for details of how these switches are 
used. This illustration refers to the switch model (KS4320) of 
the MoniCough. The settings for the fader model (KS4310) are 
slightly different, and are explained at the end of this manual.
Firstly you can set the “cough key” to be latching (ALTERNATE) 
or non - latching (MOMENTARY). 
In non - latching mode, the mic can be muted at power- up 
(switch in upper position) or live (switch in down position) at 
power- up. This effectively allows you to select the cough key as 
either a push - to - talk (switch up) or push - to - mute (switch down) 
key.
With the cough key in latching mode, you can choose the the 
mic to be “on - air”—the ON indicator is lit (switch in upper posi -
tion) at power- up, or muted—the ON indicator is unlit (switch in 
down position) at power- up. Push the cough key to toggle be -
tween on - air and muted (as shown by the indicator)
In this bottom panel, you can also  nd the controls that enable 
or disable the TALK BACK key and switch the SIDE TONE on and 
off (the use of side tone is explained in the previous section).
NOTE: If the cough key is accidentally left in the muted position 
(momentarily) by the announcer, the producer can manually 
override the mute with the remote switch function. Note that this 
is only available on the switch model, and that remote muting is 
not possible.

Talkback and intercom connection
As mentioned earlier, the MoniCough is capable of supporting 
the common industr y - standard intercom formats.
These are selected using the rotar y monitor selection switch on 
the rear panel of the unit.

Note that depending on the switch setting here, the wiring

MONI/TB 7-pin XLR connector on the rear

The meaning of the different settings is as follows:
RTS: This switch position uses the RTS IFB system. The Moni -
Cough takes the interrupt and non - interrupt lines and feeds 
them to the left and right channels respectively of the head -
phone system.
Use the INT/A and NON INT/ B level controls on the front panel of 
the MoniCough to adjust the levels of the interrupt and non - in -
terrupt signals respectively.
