PROFESSIONAL DYNAMIC MICROPHONE

2. Do not cover any part of the grille with your hand,
covering the grille alters the sound and distorts
the polar pattern increasing the chance for
feedback.

Cautions

1. If the head of the microphone is covered by hand
or brought close to the speaker, a howling sound
may be generated. To prevent this, first decrease
the volume, then place the microphone so that it is
not pointed to the speaker and that there is a
sufficient distance between the microphone and
speaker.

2. It is important to keep foreign particles out of the
grill and the windscreen because they may alter
the frequency response of the microphone. The
grill shall be periodically cleaned using warm,
soapy water, rinsed with plain water and let dry
before replacing.

3. Due to the high sensitivity of the cartridge, do not
drop it from high or apply strong shock to it.

4. To maintain the sensitivity and quality of sound
reproducing, avoid exposing it to moisture and
extreme temperatures.
