The super-cardioid e 614 is a permantly polarized condenser microphone
designed for demanding applications which require a wide frequency response,
high SPL, fast transient response and a compact design. With its frequency
response of 40 Hz to 20 kHz, the e 614 is able to capture the full sound of the
instrument, while its super-cardioid pick-up pattern isolates the microphone
from other on-stage signals.
An excellent microphone for percussion instruments, the e 614 is also an ideal
choice for woodwind and string instruments. Its excellent acoustic properties
also make it a valuable tool for home recording.

| AKG C411L Ultralight Condenser Microphone
- Ultra-light vibration pickup
- Condenser transducer in sealed enclosure
- Cable with lockable miniature XLR connector
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.

| 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.
