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-profile, 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 configuration), 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 3 TM Power Connect a power supply providing at least 12VDC to the MoniCough. 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 specifications 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 specifications. 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). SUM -3 TB SW.

Note this these drawings show the switch model, fitted 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.

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 fitted with the optional frontpanel 7-pin XLR connector, ensure that your headset is wired in the way described here before making the connection. 1 2 3 4 5 6 7 Ground MIC in (+) MIC in (-) Phones L (+) Phones L (-) Phones R (+) 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 sufficiently high post- gain signal is detected. 6 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 fitted 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 control 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 integrated headset/mic. Functionally, these setups are identical, but the side tone feed is different. In the first 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. 7 TM Live sources Ambience Guide channels Reporter Program Talkback (paging line) Output from MoniCough (announcer) To central station (master) Monitor outputs Inputs from local (L-R) sources Facility talkback/paging External DC power supply POWER EXT INT SIG.

Sets mic live or muted at power-on (nonlatching only) Sets mic live or muted at power-on (latching only) ON ON COUGH SWITCH ALTERNATE ON O N ON TB SW FUNCTION O N SIDE TONE OFF OFF Latching / Non-latching MOMENTARY Enables/disable side tone Enables/disables talkback switch 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 find 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. 9 TM Talkback and intercom connection As mentioned earlier, the MoniCough is capable of supporting the common industry-standard intercom formats. These are selected using the rotary monitor selection switch on the rear panel of the unit.

See the specifications for full details. The meaning of the different settings is as follows: RTS: This switch position uses the RTS IFB system. The MoniCough 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.
