C 568 B
Compact, short shotgun microphone
Integrated, switchable bass cut filter minimizes mechanical noise
Operates on phantom power
High directivity and wide frequency response in a relatively short shotgun make this
microphone a perfect tool for theater, sound reinforcement, and film/TV applications.
Due to its compact and lightweight design, the C 568 B is ideal for camera mount
applications. Below 500 Hz it functions as a hypercardioid microphone; above 500 Hz
the acoustic interference tube introduces increasing directivity. A switchable 12 dB/
octave 120 Hz bass cut filter effectively suppresses rumble and wind noise. The rugged,
all-metal body contains the built-in preamp. Phantom powering (9?52 V) required; foam
windscreen and stand adapter included.

Stylish and modern, the NT3 is a studio and location workhorse. With both
48V phantom and internal 9V battery operation, this R?DE is at home anywhere.
Intended for studio, stage and location work, this versatile handheld or stand
mounted microphone incorporates a true externally polarized condenser (hyper-
cardioid polar response) transducer with an internal capsule shock mounting
system, and an ultra-low noise electronic circuit that has a high immunity to R.F.
interference. Incorporating a rugged welded and heat-treated mesh head and all
metal body. The NT3 is supplied in a zip pouch with a windshield, stand mount
and thread adaptor.
