Description

CMH8A/CMH8B are condenser cardioid microphones with large

diaphragm of 1" in diameter; while CMH8C features convertible polar

patterns of cardioid, figure-of-8 and omni. Their tailored frequency

response make them ideal candidate for the recording of music program.

They are also suitable for general recording, broadcasting, stage

reinforcement, etc.

Large-diaphragm capsule of gold-evaporated membrane 1" in

diameter and 3 m in thickness.

Low-noise transformer circuit.

Wide frequency response.

has an extezrnal switch for low-cut filter and -10dB roll-off.

has a dual-membrane capsule with external switches for low-

cut filter and -10dB roll-off. At the back of the body, there is a switch

for converting polar patterns among cardioid, figure-of-8 and omni.

CMH8A has built-in low-cut filter.
