Technical specifications

The e 865 is a fully professional super-cardioid vocal microphone utilising the
very best in condenser microphone technology to achieve new standards of
quality and sound. The microphone capsule insorporates special blast/pop
protiction plate to shield the diaphragm from excessive sound pressure levels.

Rugged metal body
Extended dynamic response with pronounced presence and vocal 'punch'
Excellent feedback rejection
Very good rejection of handling noise
Very high sound pressure handling capability
Delivery Includes
1 e 865
1 microphone clip
1 pouch

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

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.
