CARVIN ENGINEERING DATA

GENERAL

The CM90E unidirectional condenser mic is
Carvin's finest studio microphone.
The CM90E has an Extremely flat response
and wide frequency range of 30Hz to 20kHz
that will give the user exceptionally accurate
results in recording, broadcast and difficult
sound reinforcement applications. The
CM90E's High sensitivity is ideal for use in
distant micing such as church choirs, pulpits
and conference rooms. Super low distortion
right up to its high overload point of
132dB/SPL makes the CM90E excellent for
micing instruments and drums too.

Microphone Features:

The CM90E is also designed for high end stu-
dio recording and broadcast applications.
Bright, clean sound. Especially good for
announcing, distant micing (choirs, pulpits,
& conference rooms) narration and dia-

quencies and completely symmetrical about
microphone axis
