User manual AKG SR 4000

[. . . ] Operate the equipment with the supplied AC adapter with a 12-VDC output. Using adapters with a different output voltage or current type may cause serious damage to the unit. If any solid object or liquid penetrates into the equipment, shut down the sound system immediately. Disconnect the AC adapter from the power outlet immediately and have the equipment checked by AKG service personnel. [. . . ] Please take a few minutes to read the instructions below carefully before operating the equipment. Please keep the Manual for future reference. Should any item be missing, please contact your AKG dealer. Operating in the 660 MHz to 865 MHz UHF range, the SR 4000 provides three selectable, quartz stabilized carrier frequencies within the 3-MHz-wide frequency band for which you ordered your WMS 40 FLEXX. This allows you to select a different frequency if one of the three frequencies does not provide adequate signal quality. The frequencies have been factory preset to make sure you can set up a multichannel system* with up to three channels with three kits operating in the same frequency band. Using a suitable combination of kits operating in different frequency bands you can even use up to nine channels simultaneously. The SR 4000 is a diversity receiver and uses two antennas in order to receive the transmitter signal at two different spots. the diversity electronics will automatically activate the antenna that delivers the better signal. An adjustable squelch will mute the receiver if the received signal is too weak so the related noise or the self-noise of the receiver will not become audible when the transmitter is switched OFF. *Ask your dealer about usable frequency bands for WMS 40 FLEXX systems with more than three channels. Turn the VOLUME control (7) on the receiver front panel all the way CW to set the receiver output to line level. â· 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 cause damage to the unit. Plug the feeder cable on the included power supply into the DC ONLY socket (13) on the receiver. Bend part of the feeder cable into a small bight, pass the bight through the strain relief (12) from above, and slip the bight over the hook on the strain relief (12). Plug the AC adapter into a convenient power outlet. To switch power to the receiver off, press ON/OFF (2) again. Your receiver can only receive the transmitter signal if a) the transmitter and receiver operate within the same frequency band; and b) the transmitter and receiver are set to the same frequency within this frequency band. If the RF MUTE LED (3b) on the receiver is lit, set the frequency selector (8) on the receiver to a position where RF MUTE (3b) goes out and the RF OK LED (3a) comes on. Move the transmitter around the area where you will use the system to check the area for "dead spots", i. [. . . ] To activate the new carrier frequency, switch the transmitter back on. Use a soft cloth moistened with water to clean the receiver surfaces. Same frequency / use transmitter with compatible frequency. Transmitter is too far away from re- 10. [. . . ]
