- Hypercardioid polar pattern
- 38 cm long
- 95° pickup angle
- For acoustically difficult environments
- Connects easily via XLR connector
The hypercardioid polar pattern with its narrow 95° pickup angle is suited best for situations where noise typically occurs from all sides (particularly in worship centers), where people talk into the microphone from a greater distance, or where several talkers are grouped side by side. Two different lengths are available. The .exible joint ensures optimum alignment of the gooseneck to any talker position. Several options are available for installation, i.e., stand, tabletop installation, and lockable.
Choosing polar patterns
Selecting the correct polar pattern for installed sound is difficult since it depends on a variety of factors. Of course the acoustics of the room play a key role. For highly reverberant rooms such as worship centers, a hypercardioid polar pattern will be the best choice to avoid high levels of unwanted noise. Correct placement of the loudspeakers is also essential. If the speakers project right at the capsule, a hypercardioid will be your best bet. The most difficult task, however, is trying to judge how the talkers will behave. For talkers who are inexperienced or move around a lot, be sure to choose a cardioid polar pattern for reliable pickup; talkers at a greater distance from the mic will be served best by a hypercardioid.

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.

The new CHM 99 Condenser Hanging Microphone provides both ease of use and a high level of functionality. There is hardly any more affordable and simpler solution for recording choirs at worship centers. Suspended from the ceiling or a beam, the hanging microphone is aligned and then fixed in the correct position. Now use the spring steel clamp to adjust the correct angle, and off you go!
The CHM 99 is available in white or black.
XY stereo recording
Using two CHM 99 hanging microphones in an XY configuration (coincident pair) is a good way to make stereo recordings, particularly of choirs. However, sound source locations are defined only by intensity differences. Adjusting the angle between the microphones determines the width and depth of the stereo image.
ORTF stereo recording
Developed by the French Broadcasting Authority, this technique differs from the XY technique by recording not only intensity differences, but also delay differences. The capsules are aligned at an angle of precisely 110° and 170 mm / 6.7 in. apart.
