User manual AKG WMS 80

[. . . ] Spill no liquids on the equipment and do not drop any objects through the ventilation slots in the equipment. Do not place the equipment near heat sources such as radiators, heating ducts, or amplifiers, etc. And do not expose it to direct sunlight, excessive dust, moisture, rain, mechanical vibrations, or shock. Be sure to dispose of used batteries as required by local waste disposal rules. [. . . ] ) In each carrier frequency table (1k, 2h, 3k) and in the Frequency List in section 12, the basic frequencies you can use simultaneously 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. Microphones, Guitar Cable (optional) The following AKG microphones have been designed specifically for direct connection to the audio input of the PT 80: C 417 L C 419 L C 420 L CK 77 L The MKG/L guitar cable from AKG lets you connect an electric guitar, electric bass, or remote keyboard to the bodypack transmitter. Prior to connecting the receiver to AC power and inserting the batteries into the transmitter, set the transmitter and receiver to the same carrier frequency. The carrier frequency tables on the transmitter (2h, 3k) and receiver (1k) and the Frequency List (section 12) on page 44 list the channel number corresponding to each carri er frequency. Be sure to assign a separate carrier frequency to each transmission channel (transmitter + receiver). 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. The transmitter and receiver of your WMS 80 system have been factory programmed for up to 15 selectable carrier frequencies. Frequency Sets Prior to powering up your WMS 80 system, check that the transmitter and receiver use the same Frequency Set. If they do not, you may not be able to find a common carrier frequency for the transmitter and receiver. The following Frequency Sets are currently available: Ordering Transmitters and Receivers If you want to order additional transmitters or receivers operating To activate the new carrier frequency, switch the transmitter back ON. (If you try to change the carrier frequency while power to the transmitter is on, the frequency will remain the same. Microphone Element Prior to switching the transmitter on, screw the microphone element CW onto the thread on the transmitter. Make sure that the end of the ribbon fixed inside the battery compartment (2f) will stick out of the battery compartment (2f). Push the upper end of each of the supplied batteries beneath the fixing flange in the battery compartment (2f) from the side and press firmly down against the battery compartment bottom. The transmitter will not function with the batteries inserted incorrectly Important: Do not try to insert the batteries straight or with the lower end first. You would risk breaking the fixing flange so the battery would not be seated securely in the battery compartment. If the batteries are in good condition, the status LED (2b) will continue glowing dimly. When the status LED (2b) illuminates brightly the batteries will be dead within about 90 minutes. Screw the supplied protective ring (2j) and the battery compartment cover back onto the transmitter CW. [. . . ] Here are a few useful hints on how to avoid problems such as sudden noise surges, phasiness (whizzing, whirring), dropouts, or clicks: 1. Make sure the transmitter will never be farther away from the receiver than 164 ft. Make sure there is a direct line of sight between the transmitter and receiver. If this is impractical (for instance, during "love duets"), check prior to the performance what frequencies will work best at close quarters. [. . . ]
