AKG C451B
AKG C451B Description:
Responding to growing demand, AKG decided to make the C 451 B with the same acoustic performance as the popular original C 451 EB + CK 1, with dramatically improved specifications.
Using an extremely light diaphragm, the new C 451 B is almost totally insensitive to handling noise.
Other features include an all-metal body for excellent protection from RF interference and high reliability for excellent results under almost all conditions.
The C 451 B is an excellent tool for accurately capturing signals rich in transients such as drums, instruments with a percussive sound, acoustic guitar, or for overhead miking.
Also available as a matched stereo pair C 451 B/ST with complete accessories in a carrying case (Soundtool case, middle size).
AKG C451B Features:
- Identical acoustics to legendary CK 1
- Precise, nearly frequency independent cardioid
- Extremely accurate signal transfer and ruler-flat on-axis frequency response
- Also available as a matched stereo pair
- Professional condenser microphone with gradient capsule.
- Its application range shall include instrument miking and recording, live recording, live sound reinforcement, lecterns and places of worship.
- Frequency range: 20-20,000 Hz; sensitivity 9 mV/PA at 1 kHz; electrical impedance: max. 200 ohms; maximum SPL: 155/145/135 dB SPL for 0.5%.; signal-to-noise ratio: 76 dB-A; switchable preattenuation pad: 0/-10/-20 dB; switchable Bass cut filter slope 12 dB/octave at 75 or 150 Hz;
- The microphone shall be capable of operating on phantom power 9 to 52 V, drawing a current of max. 2 mA. The case shall be 19mm(0.75 in.) diameter and 160mm(6.3 in.) in length.
- The surface shall be satin nickel plated and the maximum net weight of the microphone system shall be 125 g (4.4 oz.).
