Watertight Miniature UHF Belt-Pack Transmitter
Rio Rancho, NM

Some mics require RF protection to keep the radio sig-
nal from affecting the capsule, even though the trans-
mitter input circuitry is already RF bypassed.
If the mic is wired as directed, and you are having diffi-
culty with level, high noise, or poor frequency response;
RF is likely to be the cause.
The best RF protection is accomplished by installing RF
bypass capacitors at the mic capsule. If this is not pos-
sible, or if you are still having problems, capacitors can
be installed on the mic wires inside the TA5F connector
housing.
Install the capacitors as follows: Use 330 pF capaci-
tors. Capacitors are available from Lectrosonics. Please
specify the part number for the desired lead style.
Microphone RF Bypassing
Leaded capacitors:
P/N 15117
Leadless capacitors: P/N SCC330P
All Lectrosonics lavaliere mics are already bypassed
and do not need any additional capacitors installed for
proper operation.
