7. Frequencies

The transmitter and receiver of your WMS 80 system have been factory programmed for up to 15 selectable carrier frequencies. The carrier frequency label (1k) on the receiver, (2g) on the hand- held transmitter, or (3k) on the bodypack transmitter lists the Frequency Set your WMS 80 system uses and all available carrier frequencies.

7.1. Frequency Sets

Prior to powering up your WMS 80 system, check that the trans- mitter and receiver use the same Frequency Set. If they do not, you may not be able to find a common carrier frequency for the trans- mitter and receiver.

The following Frequency Sets are currently available:

Designation	Frequency	Countries
	Range (MHz)
EU58	770,6 - 773,4	EU
EU59	777,6 - 780,4	EU
EU60	785,6 - 788,4	EU
JPA	802,5 - 805,5	EU, Japan
NZ1	812,2 - 815,0	EU, New Zealand
NZ2	833,2 - 835,0	EU, New Zealand
UK69A	854,9 - 857,625	EU, Great Britain
UK69B	858,2 - 860,9	EU, Great Britain
US54	710,2 - 713,0	USA
US55	719,0 - 721,8	USA
US58	734,4 - 737,2	USA
US59	742,8 - 745,6	USA

For frequencies allocated in the various countries and frequencies suited for intermodulation-free simultaneous operation, refer to the Frequency List in section 12.

7.2. Ordering Transmitters and Receivers

If you want to order additional transmitters or receivers operating

on the same set of frequencies as your original equipment, be sure to state the designation of your original Frequency Set (1k/1l, 2i, 3k/3l) and the serial number of the original device. We need this information to make sure your new equipment will be compatible with the original units.

8. Multichannel Systems

Carrier frequencies allocated to wireless microphones differ from country to country. Depending on local frequency allocations and available carrier frequencies you can operate two to four WMS 80 systems simultaneously. (Refer to the Frequency List in section 12.)

In each carrier frequency table (1k, 2h, 3k) and in the Frequency List in section 12, the basic frequencies you can use simulta- neously and without risk of intermodulation are marked with *.

If you have any questions regarding allocated frequencies contact your dealer, the competent authority, your AKG representative, or the AKG head office in Vienna, Austria.

Alternatively, you are welcome to visit the AKG website at www.akg-acoustics.com where you can download a FREE fre- quency management program for AKG Wireless Microphone Systems.

9. Setting Up

Prior to connecting the receiver to AC power and inserting the bat- teries into the transmitter, set the transmitter and receiver to the same carrier frequency. The carrier frequency tables on the trans- mitter (2h, 3k) and receiver (1k) and the Frequency List (section 12) on page 44 list the channel number corresponding to each carri - er frequency.

9.1.Selecting the Carrier Frequency

1.Handheld transmitter: Unscrew the battery compartment

cover and the color code ring (2d or 2j) CCW.

Bodypack transmitter: Open the battery compartment (3h).

All controls are now accessible.

2.Use the supplied screwdriver (1q) to set the CHANNEL control (2g) on the handheld transmitter or (3f) on the bodypack trans- mitter to the desired channel.

3.Set the CHANNEL control (1d) on the receiver to the same channel as the transmitter.

9.1.1.Multichannel Systems

1.Be sure to assign a separate carrier frequency to each trans- mission channel (transmitter + receiver).

2.Set the transmitter and receiver to one of the frequencies mark- ed with * in the carrier frequency tables (1k, 2h, 3k).

Note: If reception on the selected carrier frequency is disturbed, set the carrier frequencies for all WMS 80 channels within the same frequency set up or down one step

with the respective CHANNEL controls (1d, 2g, 3f) on each transmitter and receiver.

This is necessary to provide the minimum frequency spacing

required for intermodulation-free multichannel operation. Important: Do not operate two or more WMS 80 channels on

the same frequency at the same time and location. This would cause unwanted noise due to radio interference.

9.1.2. Changing Carrier Frequencies

Prior to changing a carrier frequency, be sure to switch the

WMS 80 specifications

The AKG Acoustics WMS 80 is a versatile and reliable wireless microphone system designed for performers, musicians, and presenters who demand high-quality sound and ease of use. This system emphasizes user-friendly operation, ensuring that users can focus on their performance rather than technical issues.

One of the standout features of the WMS 80 is its advanced wireless technology. Utilizing a frequency range of 863-865 MHz, the system provides a stable and interference-free connection. This frequency range is recognized for its reliability in crowded environments, allowing users to perform in venues filled with other electronic devices. The system’s automatic frequency management simplifies setup, enabling quick adjustments to find the best available channel.

The WMS 80 is equipped with a variety of microphone options, including handheld, lavalier, and headworn models, giving users the flexibility to choose the microphone that best suits their application. The handheld transmitter features a dynamic capsule with a tailored frequency response that captures vocals with clarity while minimizing feedback.

An important attribute of the WMS 80 is its built-in diversity receiver technology, which helps maintain a strong and clear audio signal. The system can switch between two antennas to minimize dropouts and ensure consistent audio quality, even during movement across a stage.

Another significant feature is the ability to operate for up to 30 hours on a single set of batteries, significantly reducing the hassle of frequent battery changes during performances. Additionally, a battery status indicator provides real-time feedback on battery life, allowing performers to manage their power effectively.

The WMS 80 also includes an integrated EQ, allowing users to adjust the sound signature to match their preferences or specific acoustic environments. This customization can help eliminate unwanted frequencies and enhance the overall listening experience.

Portability is a key characteristic of this system. The lightweight design of both transmitters and receivers means they can easily be transported, making the WMS 80 ideal for touring musicians or event presenters.

In summary, the AKG Acoustics WMS 80 wireless microphone system is engineered with advanced technology and practical features, ensuring excellent performance and user satisfaction.
