High Frequency Bypass
a. When other microphones are in use, some
changes may be needed to another microphone
before adding it to the system in order to avoid
high frequency interference, as illustrated in
diagram (1).
b. When a high frequency radio wave causes
interference, it normally affects the system by
generating a persistent noise or by deteriorating
the frequency response. In an effort to
ameliorate these problems, a 330PF bypass
condenser can be added on the cartridge as
shown in diagrams (1) and (2). If this method is
not possible, another option is to add a bypass
condenser on the 4-pin XLR connector as shown
in diagrams (3) and (4).
**The Best Method
(1) Connect to two-wire condenser capsule
Add 330pF bypass capacitor
(2) Connect to three-wire condenser capsule
Add 330pF bypass capacitor
