AKG C 568B HYPERCARDIOID CONDENSER SHORT SHOTGUN MICROPHONE

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.

Technical specifications

The super-cardioid e 614 is a permantly polarized condenser microphone
designed for demanding applications which require a wide frequency response,
high SPL, fast transient response and a compact design.  With its frequency
response of 40 Hz to 20 kHz, the e 614 is able to capture the full sound of the
instrument, while its super-cardioid pick-up pattern isolates the microphone
from other on-stage signals. 
An excellent microphone for percussion instruments, the e 614 is also an ideal
choice for woodwind and string instruments.  Its excellent acoustic properties
also make it a valuable tool for home recording.

Features
Rugged design Effective rejection of incidental rear noise Excellent directivity
across the whole frequency range Full, natural sound High maximum sound
pressure level
Wide frequency response
Delivery Includes
Microphone pouch
Microphone clip MZQ 100

The Stereo wonder. The new NT4, a visually striking microphone that solves
the age-old problem of stereo recording by eliminating the need to purchase
matched pairs and the associated complex set-up bars and adaptors to get
professional results. With a fixed 90 Deg. X/Y configuration and perfectly
matched stereo condenser capsules, the NT4 lets you record any source with
immaculate stereo detail.
The NT4 has a 128 dB dynamic range, 143 dBA SPL and low self-noise. Offering
selectable battery or phantom power operation with power indicator light, the NT4
is ideally suited to both studio and location recording.
The NT4 comes supplied in a custom carry case with a windshield, XLR to mini-jack
and dual XLR cables for portable DAT or professional balanced input connection.
