User manual TASCAM KS-4320

[. . . ] 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. Note the polarity of the batteries as marked in the battery compartment when inserting batteries. [. . . ] 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. Monitor selection switch GAIN 35 40 P48 LINE C-C RTS 1 2 POWER 50 30 60 DC+12V INPUT MONI / TB OUTPUT Note that depending on the switch setting here, the wiring assignment of the MONI/TB 7-pin XLR connector on the rear panel will change. 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.

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: 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/disables side tone Enables/disables talkback switch 13 TM 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. POWE EXT INT R SIG. O N O F F B. T. SIDE TONE NON INT/B 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. The TB SWITCH FUNCTION key on the bottom panel is used to enable or disable this function. [. . . ] Is the GAIN control turned up?
