Thank you for using the Kamesan MoniCough unit. This pro­vides 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 industry
standards is also available, as is a sideband facility.

Although the MoniCough is housed in a low-profi 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 environ­ment.

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 confi 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 head­set.

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 specifi cations provided in this manual. Use of
any other power supply may damage the MoniCough and con­nected equipment. If in doubt, always check and double-check
the specifi cations.

Battery operation

Alternatively, you may choose to use four AA 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 Moni­Cough’s controls and features.

Note this these drawings show the switch model, fi tted with the
optional XLR-7 connector, which is replaced by a 1/4 -inch ste­reo jack in the standard model. The bottom panel of the Moni­Cough 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 Moni­Cough.

or:

if you have the MoniCough model fi tted with the optional front­panel 7-pin XLR connector, ensure that your headset is wired in
the way described here before making the connection.

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 suffi 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 fi tted with the
optional front-panel 7-pin XLR connector, connect your headset
to the XLR connector. Check that the connections are as de­scribed 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 ac­cordance 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 Moni­Cough can be used in different situations using the side tone fa­cility or a feed from the main console, depending on the broad­cast 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 fi 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 trans­mitted via satellite. Program material is fed back via tele­phone line to avoid lag, and the headset microphone input is
also fed back in an internal loop to the MoniCough headset.

When you use the side tone feature in this way, you must enable
it using the switch on the bottom panel (see the next section)
and adjust the volume of this side tone signal with the front
panel control.
