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.

2 MIC in (+)
3 MIC in (-)
4 Phones L (+)
5 Phones L (-)
6 Phones R (+)
7 Phones R (-)
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.

TM
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.

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 position) at power-up, or muted—the ON indicator is unlit (switch in
down position) at power-up. Push the cough key to toggle between on-air and muted (as shown by the indicator)
In this bottom panel, you can also fi 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.

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 headphone 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-interrupt signals respectively.

Operating the MoniCough
The MoniCough operation depends chiefl 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 determined 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 intercom 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.

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 active, regardless of the fader position.

Some troubleshooting tips
Your voice is not getting through from the microphone to
the program
Are you sure the ON indicator is on? Whether the mic is
live or not at power-up depends on the switch settings on
the bottom panel). In non-latching mode, this determines
whether the cough key is a push-to-talk or push-to-mute key.
Is the GAIN control turned up?
Your voice is not getting through from the microphone
to the producer when press the talkback key (or pull the
fader down)
Is the TB switch on the bottom panel enabled?
Is the GAIN control turned up?
If you cannot hear your own voice in the headphones
Is the side tone switch set on, and is the side tone volume
turned up?
You cannot hear the producer’s voice (or the program
material) in the headphones
Is the correct pager system selected?
Are the INT A (and NON INT B) volume controls turned up?

About Kamesan
Sigma Systems Engineering was started in 1972 to develop and
design professional mixers for studio and remote broadcast applications.
Today, following the “slow and steady” principle of the tortoise,
we have built up our sales and our reputation to the extent that
we now enjoy 95% of the Japanese portable mixer market.
We have concentrated on two or three main areas in our design
philosophy: compactness, in an industry which was traditionally dominated by large, heavy equipment; ease of use, since
time is always of the essence in the environments where our
products are used; and quality, to match the needs that today’s
broadcasters require.
Our head offi ce is in Shinjuku, Tokyo, and as a small company,
we are happy to listen to the ideas for product improvement
suggested by you, the customers and users of our equipment.
Making steady progress (like a tortoise, but maybe a little
faster!), we hope to meet your requirements, now and in the
future.
Visit both of our Web sites at http://www.kamesan.co.jp and
http://www.kamesan.info in order to fi nd out more about
what we’re doing, and to let us know what you are doing with
Kamesan products.
