AKG WMS MULTICHANNEL TECHNOLOGY

SETTING UP MULTICHANNEL SYSTEMS

MODULAR SOLUTIONS FOR PROFESSIONAL REQUIREMENTS

Calculating intermodulation-free radio fre- quencies requires an enormous amount of computing power. AKG used up to 150 computers operating day and night to cal- culate new sets of carrier frequencies

unless the computers were needed for other purposes. The results are available to all users of AKG wireless systems on the Internet at www.akg.com/frequencies. The Frequency Management Program available

on the AKG homepage lets you check all the radio frequencies you are planning to use for compatibility, making it easy to set up an AKG multichannel system that works perfectly from the start.

The AKG Frequency Management Program checks all the radio links you are planning to use for compatibility and potential intermodulation problems.

To make sure your wireless system will operate smoothly, we recommend checking both the frequencies your system is going to use and the frequencies of local radio and TV sta- tions, etc. with this program before setting up the system.

Frequency bands

Each of the six bands contains legal frequencies and pre- sets for reliable, intermodulation-free operation. Special frequency versions within each band are available on request. An optional programmer allows AKG staff to pro- gram these frequencies either on location (one user pre- set) or at your local AKG Service Center (all presets).

BAND 1

650-680

MHz

BAND 2

680-710

MHz

BAND 3

720-750

MHz

BAND 4

760-790

MHz

BAND 5

790-820

MHz

BAND 6

835-863

MHz

RF output (ERP)

The HT 4000 and PT 4000 transmitters are available in three different RF output versions. Each transmitter is delivered with the maximum RF output (ERP) approved for the country or region where it will be used. The RF output of a transmitter can be changed, but this can only be done by AKG Vienna.

Multichannel example 1

Each frequency band is 30 MHz wide and comprises up to 18 intermodulation-free frequencies (depending on local frequency plans). If you need more than 18 frequencies, you can use several bands. Make sure to select bands with the widest possible frequency spacing between them.

Multichannel example 2

Where local frequency plans limit the available frequency range to two bands, you can still set up a large multi- channel system. Bands 1 and 2 together provide about 25 usable frequencies in this example. Again, use bands with the widest possible spacing between them!

WMS 40, WMS 400, WMS 4000 specifications

AKG Acoustics has long been recognized as a premier brand in the professional audio industry, particularly in the realm of wireless microphone systems. Among its celebrated offerings, the WMS 4000, WMS 400, and WMS 40 series stand out for their advanced technology and robust performance, catering to a range of applications from live performances to studio recordings.

Starting with the WMS 4000, this system is engineered for versatility and reliability. 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.
