• natural and open
sound
• suitable for instrument miking applications in the studio
or on the stage
• lends itself to acoustic guitar, strings, piano and wind
instruments
d:screet™ 4090 is a high quality omnidirectional condenser
microphone. Due to its uniquely natural and open sound, the 4090 is
suitable for instrument miking applications in the studio or on the
stage.
The 134 dB SPL handling means it can be used with essentially any
instrument from acoustic guitar and strings to piano and wind
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 (4.75 in). |
