User manual AKG HEARO 777 QUADRA

[. . . ] Please read the manual before using the equipment!Specifications subject to change without notice. For other products and distributors worldwide see our website: http://www. AKG Acoustics GmbH hereby declares that the product HEARO 777 (Receiver + Transmitter) complies with the essential requirements and other relevant provisions of Directive 1999/5/EC. [. . . ] LEVEL: As long as audio signal is present at the transmitter input, the green LEVEL label will flicker in step with the signal level. Since signal levels are controlled automatically, the transmitter has no input gain knob. When you place the headphones in the receptacles, the batteries inside the headphones will be charged automatically. CHARGE: This label indicates the charging function status: The CHARGE label illuminates to indicate the batteries inside the headphones are being charged. Since the charging circuitry operates independently from the rest of the transmitter circuitry, the CHARGE label will light even if the transmitter is OFF. The CHARGE label will remain dark when no current flows from the transmitter through the charging contacts to the batteries inside the headphones (transmitter is not connected to power, no headphones resting on the transmitter, no batteries inside the headphones, batteries inserted incorrectly, contaminated charging contacts). Before connecting the transmitter to your audio source, switch the audio source OFF. Plug the red RCA connector (right channel) on the supplied jack cable into the red AUDIO IN R socket (13) and the white RCA connector (left channel) into the white AUDIO IN L socket (13) on the transmitter rear panel. If the headphones output on your equipment is a 1/4" jack, plug the supplied mini jack to 1/4" adapter jack onto the jack cable. Before connecting the transmitter to your audio source, switch the audio source OFF. Use the supplied RCA cable to connect the white LINE OUT L or REC OUT L jack on your audio source to the white AUDIO IN L jack (13) on the transmitter rear panel and the red LINE OUT R or REC OUT R jack to the red AUDIO IN R jack (13). Alternatively, you can use the supplied jack cable: 1. Plug the white RCA connector (left channel) on the jack cable into the white LINE OUT L or REC OUT L socket on your audio source and the red RCA connector (right channel) into the red LINE OUT R or REC OUT R socket. Playing back two audio signals at the same time may cause severe distortion. Check that the AC voltage stated on the supplied AC adapter is identical to the AC voltage available where you will use your system. Using the AC adapter with a different AC voltage may cause damage to the unit. For physical reasons that are not related to the quality of the product, extremely strong interference sources may affect reception. In order to maintain interference-free listening pleasure, do not operate your HEARO 777 in the close vicinity of radio equipment, cellular telephones, or directly above TV or computer monitor picture tubes. The supplied connecting cables are long enough to allow the transmitter to be placed at a safe distance from interference sources. Reflections off metal surfaces may reduce the range of your transmitter. Therefore, be sure to place the transmitter at least 8 inches (20 cm) away from any kind of metal surface. Operating switches on or connecting the transmitter to your audio source may cause clicks which at high volume settings may affect your hearing. [. . . ] The MODE and FREQ settings will be the same as those you have selected before switching the transmitter off. (As delivered , the transmitter is set to STEREO mode and FREQ 1. ) The label backlighting will come on every time you switch the transmitter on even if you switched the backlighting off before. If there is audio signal present at the transmitter input, the LEVEL label (10) will flicker in step with the signal. [. . . ]
