INPUT JACK
The input on the UM200 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/MUTE/OFF SWITCH
Turns the battery power on and off. The center position is an "audio mute" which should be used when setting the
MIC LEVEL control to turn off the sound from the microphone during this adjustment. Even when the switch is
turned off or on aburptly, the pilot tone muting system prevents "thumps" or transients from occurring.
"ON" LAMP
Glows brightly when the battery is good. A weak or dim lamp means that the battery is weak. When the light goes
out there is about half an hour of operation left. If the lamp fails to light, the battery should be replaced. The
power lamp should light up in both the "MUTE" and "ON" positions of the POWER/MUTE SWITCH.
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 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 course 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 transmitters range.
