CMH

Handheld Microphones

Properties

  • cardioid or supercardioid
  • built-in protection from plosive sounds (“popping”) and handling noises
  • also suitable for speech pickup in the studio

Order number

  • No. 143001 CMH 64
  • No. 143002 CMH 641

Description

The SCHOEPS CMH is a wired handheld or soloist's microphone with particular immunity to plosive noise ("popping"). Because of its well-balanced frequency response it can also be used for speech pickup.

The directionality and the low-frequency rolloff of the SCHOEPS CMH microphones reduces the risk of feedback. Using the microphone at short distances increases the proportion of direct sound, and balances the built-in low-frequency rolloff with proximity effect.

The ”popping” effect on spoken consonants is substantially reduced by the built-in pop filter, and is even further reduced by the low-frequency rolloff of the microphone.
