User manual AKG HT 40

[. . . ] When scrapping the equipment, remove the batteries, separate the case, circuit boards, and cables, and dispose of all components in accordance with local waste disposal rules. This Manual contains important instructions for setting up and operating your equipment. Please take a few minutes to read the instructions below carefully before operating the equipment. [. . . ] Pull the battery compartment lid (4) down to remove it from the transmitter. If you do, the batteries will not be held in place properly and may cause a rattling noise. The transmitter will not function with incorrectly inserted batteries. If the batteries are in good condition, the status LED (2) will extinguish. If the status LED (2) illuminates the batteries will be dead within about 50 minutes. To close the battery compartment, slide the battery compartment lid (4) onto the battery compartment from below to the point that it will click shut. Switch power to the receiver on and check the setting of the VOLUME control: Fully CCW if you connected the receiver to a microphone input. Since the HT 40 handheld transmitter has been designed specifically for the integrated microphone element, there is no need to set gain on the handheld transmitter. Talk or sing into the microphone and set the levels on your mixer or amplifier referring to the appropriate instruction manual or by ear. Slide the supplied black clip onto the transmitter to the point that it snaps into place with an audible click. Move the transmitter around the area where you will use the system to check the area for "dead spots", i. , places where the field strength seems to drop and reception deteriorates. If you find any dead spots, try to eliminate them by repositioning the receiver. The RF LED on the receiver going out means no signal is being received or the squelch is active. Switch power to the transmitter ON and/or move closer to the receiver, to the point that the RF LED on the receiver will come back on. The following sections contain useful hints on how to use your HT 40 handheld transmitter for best results. 1 Working Distance and Proximity Effect Basically, your voice will sound the bigger and mellower, the closer you hold the microphone to your lips. Moving away from the microphone will produce a more reverberant, more distant sound as the microphone will pick more of the room's reverberation. [. . . ] Feedback may also be triggered by resonances depending on the acoustics of the room or hall. With resonances at low frequencies, proximity effect may cause feedback. In this case, it is often enough to move away from the microphone a little to stop the feedback. [. . . ]
