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
