4091 Omnidirectional Microphone, Lo-Sens, P48 |
|
ProductCode: 4091

• excellent for
percussion
• natural and open sound
• handles high sound pressure levels with ease
D:screet™ 4091 is a high quality omnidirectional condenser
microphone. Due to its uniquely natural and open sound, the 4091 is
suitable for instrument miking applications in the studio or on the
stage.
The 144 dB SPL handling means it can meet just about any challenge
including miking an electric guitar amp. An excellent microphone
for percussion instruments, the 4091 is also an ideal choice for
wind and string instruments. Due to their remarkably linear
frequency response in the 20 Hz to 20 kHz range, sound system
engineers can also use these mics for sound system alignment,
testing and tuning.
The rugged and compact design features a 5.4 mm diameter
pre-polarized condenser capsule in a tapered body measuring just 12
cm (4.76 in). |
