6. 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).
