INPUT JACK
The input on the UM200C accommodates virtually every lavalier, hand-held or shotgun microphone available. Line
level signals can also be accommodated. Use a Switchcraft TA5F connector on the cord. See the separate sheet
titled “Transmitter 5-Pin Input Jack Wiring” regarding the correct connections for various microphones, and
other sources.
ON/OFF SWITCH
Turns the battery power on and off. Even when the switch is turned off or on abruptly, the pilot tone muting system
prevents “thumps” or transients from occurring.
“ON” LAMP
Glows brightly when the battery is good and the ON/OFF switch is ON. A weak or dim lamp means that the battery is
weak. When the light goes out there is about 15 to 30 minutes of operation left. If the lamp fails to light, the battery
should be replaced.
The “ON” lamp is connected to a precision battery test circuit that continuously monitors battery voltage. The LED is
at full brightness with a new 9 Volt alkaline battery. As the battery voltage drops during use, the LED brightness will
also decrease. After about 4.5 hours of operation the battery voltage will be about 6.5 Volts and the LED will be
completely out.
FREQUENCY ADJUST
These two rotary switches adjust the center frequency of the carrier. The 1.6M is
a coarse adjustment and the 100K is the fine adjustment. Each transmitter is
factory aligned at the center of its operating range. The default position of the
frequency select switches is in the center of the transmitter’s range.
