capacitors can be installed on the mic wires inside the TA5F connector housing.
The 330 pF capacitors are available from Lectrosonics. Please specify the part number for the desired lead style.
Leaded capacitors: P/N 15117
Leadless capacitors: P/N SCC330P
Note
The Lectrosonics M150 lavalliere mic is already bypassed correctly for use with the LM.
LINE LEVEL SIGNALS
The normal hookup for line level signals provides 40 dB of attenuation allowing signal levels much higher than 3 V to
be applied without limiting. The normal hookup configuration can be modified for situations that require higher levels
of headroom, or lower levels of attenuation. (See illustration below.)
Normal hookup configuration connects the Signal Hot (Audio) to pin 5, Signal Gnd (Shield) to pin 1, and both pins 3
and 4 jumped to pin 1. This configuration provides 40 dB attenuation allowing signal levels greater than 3 V to be
applied without limiting.
If even more headroom is required, insert a 100 k resistor in series with pin 5 (Audio). Put this resistor inside the
TA5F connector to minimize noise pickup.
For situations where lower than normal line levels (less than 1 V) are expected, use the Lower Line Level Hook Up:
Signal Hot (Audio) to pin 5, Signal Gnd (Shield) to pin 1, and pin 4 jumpered to pin 1. This configuration provides 20
dB attenuation to the input signal.
