Congratulations, you’ve just become the owner
of a professional, high quality Gatt Audio
®
dynamic
microphone. If you follow our operating instructions
it will last you a lifetime.
General Description:
Both
DM-50
and
DM-100
dynamic
microphones are meant to be used in live
performance,
broadcasting
or
recording
environments. The cardioid characteristics of the
element ensure rejection of any unwanted ambient
sounds, thus minimizing feedback problems. Also, it
can be used with high sound pressure levels
without any problems. The low impedance output
guarantees hassle free operation with full
bandwidth signal over long cable runs.
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
should 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 or apply strong shock to it.
4.
To maintain the sensitivity and quality of sound
reproducing, avoid exposing it to moisture and
extreme temperatures.
