ENGLISH Explanation terms Troubleshooting B Bit rate This expresses the read amount per 1 second of video/audio data recorded in a disc. D Dynamic range The difference between the maximum undistorted sound level and the minimum sound level that is discernible above the noise emitted by the device. F Finalize This is processing that enables playing back of disc of CD, which was recorded using a recorder, by other players. M MP3 (MPEG Audio Layer-3) This is an internationally standardized audio data compression scheme, using the "MPEG-1" video compression standard. It compresses the data volume to about one eleventh its original size while maintaining sound quality equivalent to a music CD. MPEG (Moving Picture Experts Group), MPEG-2, MPEG-4 These are the names for digital compression format standards used for the encoding of video and audio. Video standards include "MPEG-1 Video", "MPEG2 Video", "MPEG-4 Visual", "MPEG-4 AVC". Audio standards include "MPEG-1 Audio", "MPEG-2 Audio", "MPEG-4 AAC". P Protection circuit This is a function to prevent damage to components within the power supply when an abnormality such as an overload, excess voltage occurs or temperature for any reason. In this unit, the power indicator blinks and the unit enters standby mode when an abnormality occurs. S Sampling frequency Sampling involves taking a reading of a sound wave (analog signal) at regular intervals and expressing the height of the wave at each reading in digitized format (producing a digital signal). The number of readings taken in one second is called the "sampling frequency". The larger the value, the closer the reproduced sound is to the original. Speaker impedance This is an AC resistance value, indicated in Ω (ohms). Greater power can be obtained with this value smaller. W WMA (Windows Media Audio) This is audio compression technology developed by Microsoft Corporation. WMA data can be encoded using Windows Media® Player Ver.7, 7.1, Windows Media®Player for Windows® XP and Windows Media® Player 9 Series. To encode WMA files, only use applications authorized by Microsoft Corporation. If you use an unauthorized application, the file may not work properly. If a problem occurs first check the following: 1. Are the connections correct? 2. Is the set being operated as described in the owner's manual? 3. Are the other components operating properly? If this unit does not operate properly, check the items listed in the table below. If the problem persists, there may be a malfunction. In this case, disconnect the power immediately and contact your retail outlet. GGeneralH Symptom Set does not operate properly. Display not lit and sound not produced when power switched to on. Display lit but sound not produced. Display is off. Power turns off suddenly and power indicator flashes red. (Flashes at 0.5 second intervals) Power turns off suddenly and power indicator flashes red. (Flashes at 0.25 second intervals) Cause • External noise or interference is causing the set to malfunction. • Power cord not plugged in securely. Countermeasure • Reset the microprocessor. • Check the connections on the set's rear panel and the connection of the power plug to the power outlet. • Wrong input source selected. • Volume control set to minimum. • MUTING is on. • Select the appropriate input source. • Turn volume up to suitable level. • Switch off MUTING. • The Dimmer setting is set to "OFF". • Protection circuit activated due to a rise in internal temperature. • Core wires of two speakers are touching each other or a core wire is sticking out of the terminal and touching the set's rear panel, activating the protection circuit. • Set is damaged. • Set to something other than "OFF". • Turn off the power, wait for the set to fully cool down, then turn the power back on. • Place the set in a well-ventilated location. • First unplug the power cord, then twist the core wires tightly or terminate the speaker cables, then reconnect. • Turn off the power and contact a DENON service center.
