Audio Technica U853AW Cardioid condenser hanging microphone

The white-finished version of U853A, the U853AW cardioid condenser hanging microphone is ideal for speech, theater, orchestra and choir sound reinforcement and recording. The microphone's fast transient response and low distortion characteristics allow every complex detail to be heard with all its impact-rich, vibrant qualities faithfully reproduced. Equipped with UniGuard® innovations that offer unsurpassed immunity from radio frequency interference, the U853AW accepts interchangeable elements, available in cardioid, hypercardioid, omnidirectional and UniLine® line cardioid polar patterns. The battery- or phantom-powered microphone also offers an 80 Hz low-cut UniSteep® filter that reduces pickup of low-frequency ambient noise.

A History of Sound: The C 747, the so called „pencil microphone“, was first built in 1987. Due to its excellent technical specifications, especially the wide and flat frequency range, it was used for the recording of all kinds of musical instruments, even those with very low frequencies. Because of its brilliant sound reproduction and its inconspicuous optical appearance, it was quickly known as an ideal overhead microphone.
Thank to the narrow polar pattern it solved the crosstalk problem (when recording multiple instruments at once) and the problem of picking up sounds from distant spots in a room. But for all that, due to the help of the acoustically well balanced, short interference tube, it didnʼt face one of the biggest problems of most shotgun microphones – the change of the polar pattern over the frequency. This is one of many reasons why this microphone found its way into a great number of Broadcast Stations, Recording Studios, Theatres, Opera Houses, Churches, Conference Rooms and Lecture Halls.

Another big advantage of the C 747 is that the microphone will not change the sound or level too much even when the person speaking is moving a lot. So it came that the C 747 finally found its way into installed sound systems as a perfect speech and lectern microphone. The C 747 is now one of the most versatile microphones in the AKG product range and over the years it has been available in various versions and model types such as hanging module, capsule for modular gooseneck microphones and in a boundary layer microphone.

Whatʼs New in V11: As it is more and more used in conference applications, we carefully redesigned the C 747 to better cope with some specific installed sound issues.
The new C 747 V11 will have an integrated RFi shield to block out unwanted interference by mobile phones, wireless mics and the like. Also we have fine tuned the frequency response to give especially the spoken word an outstanding presence, without changing the flavour of the classic C 747 sound.

An enhanced polar pattern provides consistent off-axis rejection to control ambient noise and feedback in acoustically difficult environments. This makes the C 747 V11 an excellent choice for noisy discussion groups or reverberant pulpits while it is forgiving enough to clearly pick up talkers moving around in front of the microphone. A switchable LF roll-off filter suppresses mechanical noise. The low-impedance transformerless preamp operates on 9 to 52 V phantom power.
The C 747 V11 ships with an extensive accessory set including a shock mount/adapter, mini gooseneck, stand adapter, mounting clamp, thread link, and windscreen.

SPECIFICATIONS:

• Cardioid instrument microphone with miniature mounting bracket
• High mechanical-noise attenuation
• Including wireless direct adapter for easy use with AKG pocket transmitters
• Detachable microphone cable
• Ideal for miking up accordions and guitar, piano, keyboard, or organ amplifiers
