Cardioid Condenser with 10dB Attenuator and 3 Position Low-Cut Filter
One of the world's great studio microphones, the SM81 provides precise, detailed sound reproduction, is excellent for studio recording, and is rugged enough for live sound reinforcement.
- A standard for acoustic instruments, including guitar and cymbals
- Selectable, low-frequency response -- either flat, 6dB/octave roll-off, or 18 dB/octave roll-off
- Built-in, switchable 10 dB attenuator for use in high SPL situations
- Phantom power only
- Windscreen included
- Low noise and high output clipping
- Cardioid condenser
- Frequency response: 20 to 20,000 Hz
| This new mic is a performance / price breakthrough. It has an acoustically identical version of the legendary CK1 capsule that is permanently mounted. This combination can handle high output transients as well as subtle harmonics. Also included are switchable 75 and 150Hz 12dB per octave rolloff, and switchable -10 & -20 dB input pad. It is a single pattern (cardioid), and has a frequency response of 20 to 20kHz with 135 dB SPL. Requires 12 to 48V phantom power. Kit comes with bag, windscreen and clip.
For more than twenty years, the AKG C 451 with the CK 1 condenser capsule was a standard item on tour riders for sound companies and required by leading engineers for studio projects. When it was discontinued in 1993, there was still a big demand for this microphone. AKG now has an updated version of this classic microphone.
The new C 451B provides the same frequency response as the legendary CK 1 with the same slight high-end rise that was the signature of the original. This characteristic makes the C 451B an ideal tool for capturing signals rich in transients such as acoustic guitars, snare drums, hi-hats and for overhead micing of drum kits. The C 451B?s response eliminates the need for heavy EQ on these instruments.
The new C 451B has also benefited from newer electronic technology with machine soldering and surface-mount components that improve noise performance and make the microphone much more reliable than the original.
Other special features include switchable 10 dB and 20 dB preattenuation pads and switchable low cut filters at 75 Hz or 150 Hz. Standard accessories included are an SA 40 stand adaptor, W 90 windscreen and a rugged zippered bag. Each C 451B also comes with an individual frequency response printout.
Three-year warranty.

Weighing only 18 grams (0.6 oz.), this ultra-light condenser pickup is ideal for acoustic guitar, mandolin, violin, and most other stringed instruments. The C 411 will give a clear and uncolored sound without changing the balance of the instrument. Attaching the C 411 on or near the bridge or anywhere else on the instrument is easy with the included non-marring, reusable, solventfree adhesive compound.
C 411 PP: For hardwire applications, with standard XLR connector for phantom powering. |
C 568 B
Compact, short shotgun microphone
Integrated, switchable bass cut filter minimizes mechanical noise
Operates on phantom power
High directivity and wide frequency response in a relatively short shotgun make this
microphone a perfect tool for theater, sound reinforcement, and film/TV applications.
Due to its compact and lightweight design, the C 568 B is ideal for camera mount
applications. Below 500 Hz it functions as a hypercardioid microphone; above 500 Hz
the acoustic interference tube introduces increasing directivity. A switchable 12 dB/
octave 120 Hz bass cut filter effectively suppresses rumble and wind noise. The rugged,
all-metal body contains the built-in preamp. Phantom powering (9?52 V) required; foam
windscreen and stand adapter included.
