AKG C 4500B-BC

C 4500B-BC

With the ever-increasing number of broadcast stations going "digital" - at least with their automatic control facilities - the on-air studios are more and more clustered with control computers.

These computers and their associated monitors radiate electro-magnetic r.f. fields which can be a serious problem for nearby dynamic microphones.

Not so with condenser microphones with transformerless output, inherently immune to external electro-magnetic fields.

AKG's solution to this increasingly imminent problem is the new C 4500 B-BC, a large-diaphragm condenser microphone, especially tailored to the needs of on-air radio announcers.

The major issues of this new development are:

• The front-end firing capsule position for most effective close-to-the-mouth placement with the least visual disturbances for the radio announcer
• Reduced proximity effect by inherent minimum working distance to the capsule of about 2 to 3 inch
  
• Extremely effective internal pop-screening through a newly developed multi-layer pop filter between the front grille and the capsule
  
• An additional 120 Hz roll-off filter for both, further reduction of remaining proximity effect and suppression of rumble or structure-born noise
  
• The -20 dB pre-attenuation pad, which enables the user direct replacement of dynamic microphones without altering the adjusted gain structure on the associated equipment
  
• Extremely "voice-friendly" acoustics, requiring no further processing gear after the microphone.
  
  Highly effective electro-magnetic screening by the use of an all-metal housing and double screening of all acoustically open sections of the housing
• The included spider suspension H 100 keeps problematic low frequency vibrations away from the microphone and also protects the microphone from abuses of more temperamental talents in front of it.
  
• The included W 4000 is a cellular foam wind and pop screen offering additional protection when working close to the C 4500 B-BC.
