User manual AKG PERCEPTION WIRELESS

[. . . ] To avoid hum or interference, route all audio lines, particularly those connected to the microphone inputs, away from power lines of any type. If you use cable ducts, be sure to use separate ducts for the audio lines. Be sure to disconnect the AC adapter from the power outlet before cleaning the equipment. Never use caustic or scouring cleaners or cleaning products containing alcohol or solvents since these may damage the enamel and plastic parts. [. . . ] Before setting up your Perception wireless, check that the transmitter and receiver are tuned to the same frequency. The wireless connection will not work if the receiver and transmitter are tuned to different frequencies. or the shadow effects of musicians and other people may weaken or cancel the direct transmitter signal. For best results, set up the receiver as follows: 1) Place the receiver near the performance area (stage). Make sure, though, that the transmitter will never be any closer to the receiver than 10 ft (3 m). 2) Check that you can see the receiver from where you will be using the transmitter. 5 m) away from any large metal objects, walls, scaffolding, ceilings, etc. Use an XLR cable to connect the BALANCED output on the back of the receiver to a balanced microphone input (XLR socket) on the mixer or amplifier. To avoid hum interference, do not use audio cables that are longer than 10 feet (3 m). Check that the AC mains voltage stated on the included power supply is identical to the AC mains voltage available where you will use your system. Using the power supply with a different AC voltage may wreck the unit. Plug the feeder cable of the included power supply into the DC IN socket on the receiver. Pull the battery compartment cover off the transmitter in the direction shown by the arrow. insert the supplied battery into the battery compartment conforming to the polarity marks. The transmitter will not function if you insert the battery the wrong way round. If you use a rechargeable battery, the LED will change to red approximately 15 minutes before the battery goes flat. To close the battery compartment, slide the battery compartment cover onto the battery compartment from below until the snap hook engages. 1) blinks for 3 seconds after which it is displayed without blinking, indicating that the selected channel is active. During those 3 seconds, press CHANNEL to obtain the required channel number. Once you have reached the required channel number, the display blinks for a further 3 seconds after which the channel you have just selected becomes active. 4) Speak or sing into the microphone and watch the LEDs on the receiver: · If the CLIP LED does not light up at all, the input sensitivity of the transmitter is too low. If the CLIP LED lights up frequently or all the time, the input sensitivity of the transmitter is too high. [. . . ] 4) As soon as the windshield has dried, replace it in the wire-mesh cap and screw the wiremesh cap onto the handheld transmitter. Transmitter has a different frequency range or is tuned to a different frequency from the receiver. Use a transmitter with the same frequency range as the receiver or tune both to the same frequency. Transmitter is too far away from receiver or squelch level set too high. [. . . ]
