Microphone Features:
•
Flat, wide-range frequency response for exceptionally
clean and natural reproduction of both music and speech
•
Classic cardioid polar pattern, uniform with frequency and
symmetrical
about axis, to provide maximum rejection and
minimum coloration of off-axis sound
•
Internal
“air suspension” shock isolation virtually eliminates
mechanical noise transmission
•
Highly effective pop filter eliminates need for any add-on
protection against explosive breath sounds, even for
close-up vocals or narration
•
Extremely good rejection of electromagnetic hum due to
built-in hum rejection system
•
Bass rolloff and mid-range emphasis (presence boost)
controls with graphic display of response setting. (See
Figure 1)
•
Yoke mounting with captive stand nut for easy mounting
and dismounting provides precise control of microphone
position
•
Rugged
construction and excellent
cartridge protection for
outstanding
reliability
