AKG WMS MULTICHANNEL TECHNOLOGY

WMS frequency band with TV transmitter

If you are faced with interference caused by a television station, select the carrier frequency of the wireless microphone system such that there is a separation of at least 500 kHz from the video carier, and 200 kHz from the audio carrier. Caution: changing a single carrier frequency may result in chaotic intermodulation in the entire multichannel system!

The Frequency Management Program from AKG provides a simple solu-tion to this problem as it automatically finds frequencies that wll not interfere with one another.

 

Intermodulation

 

The nonlinear characteristics of a transmission link may

 

cause intermodulation problems. Intermodulation produc-

 

ts do not increase linearly as f1 and f2 rise in amplitude

 

of, but significantly faster. 3rd order intermodulation arti-

 

facts are the biggest problem that beset wireless systems,

 

as they are strong enough to be clearly received.

 

Intermodulation

 

The simultaneous use of several radio sources results in

 

intermodulation products in the frequency spectrum. If, for

 

example, a third radio source (microphone) is used on the

 

same frequency as that of a 3rd order intermodulation

 

product of microphones A and B, microphone C is very like-

 

ly to pick up a lot of intermodulation noise. This is why it

 

is essential to test all the radio frequencies you wish to

 

use before each performance.

It features a sophisticated transmission diversity system that minimizes dropouts and ensures clear audio quality. The WMS 4000 offers an extensive frequency range, accommodating diverse environments and frequencies. A standout feature is its digital pilot tone, which automatically mutes the transmitter when it is switched off, effectively preventing unwanted noise during transitions. With a range of up to 300 meters, the WMS 4000 is ideal for large venues, allowing performers ample space to move without compromising sound quality.

Next, the WMS 400 series maintains the high standards set by its predecessor while providing a more accessible option for mid-level performers. It combines ease of use with quality audio performance, boasting a user-friendly interface that simplifies setup and operation. The WMS 400 employs an efficient frequency management system, which automatically scans the environment to select the best frequencies available, ensuring optimal performance with minimal interference. The system also features a rugged metal chassis, enhancing durability for live applications.

The WMS 40 series serves as an entry-level solution, perfect for beginners and small venues. It is lightweight and features a straightforward design, making it easy to operate for users without extensive technical knowledge. One of its most notable characteristics is its plug-and-play functionality, allowing for quick setup without complicated configurations. The WMS 40 series also offers excellent sound quality through its crystal-clear audio transmission and robust reception, making it a popular choice for schools, theaters, and small events.

All of these systems benefit from AKG's heritage in sound engineering, incorporating advanced audio processing technologies that ensure superior sound fidelity. They also come with a variety of microphone options, including handheld, lavalier, and headworn microphones, providing flexibility to meet different performance needs. Whether for a professional stage or an intimate setting, the AKG WMS series delivers outstanding performance, reliability, and user-friendly features that cater to a wide range of audio applications.
