Surround applications

Changing the pick-up pattern

There are two different ways of changing the pick-up pattern of the microphone.

If the microphone level has to be changed infrequently:

At the mixing console, set the preamplification to the same value in both channels.

Vary the pick-up pattern by using the level control and the phase switch of the rear channel.

The level control of the front channel stays in the same

position.

If the microphone level has to be changed frequently:

At the mixing console, set the level controls to the same value and couple them mechanically or electrically.

Change the pick-up pattern by using the pre-set gain control and the phase switch of the rear channel.

As a result of the symmetry of the microphone, it is also possible to create any desired rear pick-up pattern. For this purpose the microphone signals are additionally routed to two other channels, whereby front and rear channel exchange roles. The settings are then made in the same way as described above and the rear pick-up patterns can be freely selected. Both pick-up patterns are then available simultaneously, for example for a surround front channel and a surround rear channel. With two MKH 800 TWIN, four surround channels can be created in this way.

If only the cardioid pick-up pattern is required for the front and rear channels, the microphone signals can also be used directly. This minimises the necessary effort.

With an MKH 800 TWIN and a figure-8 microphone (e.g. MKH 30) full surround-sound recording using the double MS technique (MSM) can be done. As is common with the MS technique, the figure-8 microphone is positioned above the MKH 800 TWIN and directed to the left. The front and rear left and right surround channels are produced by matrixing the figure-8 signal and the front and rear signals of the MKH 800 TWIN.

By combining the front and rear signals of the MKH 800 TWIN, a centre channel with any pick-up pattern can be achieved and even a centre rear channel is possible if required. In spite of the wide range of options, post- production still only requires the original microphone signals to be saved, i.e. only three signals for five or six surround channels.

MKH-800 specifications

The Sennheiser MKH-800 is a distinguished microphone celebrated for its superb sound quality and versatile applications. Renowned in the fields of broadcasting, music production, and filmmaking, the MKH-800 captures audio with a clarity that is both precise and natural.

One of the main features of the MKH-800 is its variable polar pattern. This microphone allows users to choose among cardioid, omnidirectional, and figure-eight pickup patterns. This flexibility is essential for various recording environments, enabling users to adapt to different acoustics and sound sources effectively. Whether capturing a solo vocalist or an entire ensemble, the MKH-800 delivers outstanding results.

The microphone utilizes a sophisticated RF (radio frequency) technology, which empowers it to operate exceptionally well in high-SPL (sound pressure level) situations. This feature makes it an ideal choice for both studio and live sound applications. The RF technology also ensures low self-noise levels, providing clean, uncolored audio reproduction. As a result, the MKH-800 is particularly favored for its transparency and fidelity in recording vocals and instruments.

Another fundamental characteristic of the MKH-800 is its rugged construction. Designed to endure the rigors of professional use, it features a durable yet lightweight casing. This robust design allows it to perform reliably in challenging conditions, making it suitable for field recordings and outdoor applications.

In addition, the MKH-800 boasts a frequency response range of 20 Hz to 50 kHz, enabling it to capture the full spectrum of human hearing and beyond. This wide frequency response contributes to its ability to reproduce sounds with excellent detail and richness. Additionally, the microphone's low-frequency roll-off switch provides further versatility, ensuring optimal performance in different recording environments by eliminating unwanted low-frequency rumble.

The Sennheiser MKH-800 is compatible with various audio interfaces, making it easy to integrate into existing setups. Its diverse applications and superior sound quality make it a favorite among audio engineers and professionals. Overall, whether in a studio setting or on location, the Sennheiser MKH-800 stands out as a premier microphone that delivers exceptional audio performance and versatility, embodying Sennheiser's commitment to quality and innovation.
