User manual CARVIN U7000

[. . . ] CARVIN ENGINEERING DATA INTRODUCTIONS U7000/U7500 Wireless System Congratulations on your purchase of the U7000 and U7500 Professional Wireless System. These systems include a receiver and either a Lavaliere mic, a handheld mic with transmitter, a headworn mic, or a body-pack transmitter for guitar, . The receiver features true UHF diversity reception. Two antennas feed two completely independent RF sections on the same frequency. [. . . ] SQUELCH CONTROL The squelch control is preset at the factory, but can be adjusted if you must use the system in an area with considerable RF interference. If there is audio output from the receiver when your transmitter is off, adjust the squelch control so the system will receive the signal from your transmitter but "squelch" or eliminate the unwanted background RF noise. This adjustment can cause a reduction in useable range of the wireless transmitter, so set the control to the lowest position that reliably mutes the unwanted RF signals. ACTIVE DIVERSITY CHANNEL LED (On U7000 UHF Receiver only) The A and B LED indicate which antenna signal is being used. This diversity receiver will automatically choose the stronger of the two. AF LEVEL LED The AF level is displayed by an LED meter, which indicates the strength of the audio signal received. RF LEVEL LED The RF level is displayed by an LED meter, which allows you to estimate the RF power with which a transmitted signal is received. If less than 2 LED, reception will become noisy.
