Beta 27 je kondenzátorový mikrofon konstruovaný pro profesionální ozvučení a studiové nahrávání. Jeho plochá frekvenční charakteristika a a nízký vlastní šum poskytují dobrý výkon i v náročných prostředích. Superkardioidní charakteristika zajišťuje vysoký zisk, před zpětnou vazbou a maximální izolaci od jiných zvukových zdrojů - minimalizace přeslechů.

The Beta 27 side-address condenser microphone is precision engineered for professional sound reinforcement and project studio recording applications. Its flat frequency response and low self-noise provide unerring performance in demanding environments. A tight supercardioid pattern ensures high gain-before-feedback and maximum isolation from other sound sources.

  • Supercardioid polar pattern specifically targets the sound source consistently with greatly minimized bleed from off-axis sound sources
  • Tailored for superior transient response from a low-mass, 1” externally-biased, ultra-thin 24 Karat gold-layered Mylar® diaphragm
  • Flat, neutral frequency response for natural reproduction on stage or in the studio
  • 3-position switchable low-frequency filter helps reduce unwanted background noise or counteract proximity effect for consistent, extended lowend
  • -15 dB switchable attenuator handles extremely high SPLs with ease
  • Premium electronic components and gold-plated internal and external connectors
  • Internal pop filter with three separate mesh layers reduces wind and breath noise.
