[. . . ] Do not use any type of abrasive pad, scouring powder or solvent such as alcohol or benzine. Before operating the amplifier, check that the operating voltage is identical with your local power supply. The amplifier is not disconnected from the AC power source as long as it is connected to the wall outlet, even if the amplifier itself has been turned off. If you are not going to use the amplifier for a long time, be sure to disconnect the amplifier from the wall outlet. [. . . ] The signal input from a digital jack is not output to the analog REC OUT jacks. Sound adjustments do not affect the signal output from the DAT/MD OPTICAL OUT, DAT/MD REC OUT, and TAPE REC OUT jacks. You can also add audio from a variety of audio sources when editing a video tape. For example, insert the laser disc you want to record from into the LD player. insert a blank video tape into the VCR (VIDEO 1 or VIDEO 2) for recording. Start recording on the recording VCR and then start playing the video tape or laser disc you want to record. You can record sound from a different audio source onto a video tape while copying from a video tape or laser disc For example, you can record video signal from a laser disc in combination with audio signal from a CD. while recording , press MODE to display "A: ______ (AUDIO SELECT)" and rotate FUNCTION to select the audio source. The audio from that source will be recorded onto the audio track of the video tape instead of the audio from the original. Do the procedure below to adjust the delay time for the center and rear speakers. Use the remote while seated in your listening position to adjust the volume of each speaker. Also, since this amplifier uses Digital Signal Processing (DSP), you can adjust the sound parameters electronically. DSP automatically converts analog audio signals to digital, which lets you adjust the sound with virtually no degradation in sound quality. Once you customize the sound fields, they are stored in memory unless the amplifier is unplugged for about 1 week. To change a customized sound field, make new adjustments to the sound field. For a sound source with Dolby Pro Logic data When the DOLBY NORMAL SURROUND or ENHANCED SURROUND sound field is selected or the DIRECT PASS button lights up: "PRO LOGIC" appears and the Dolby Pro Logic sound is decoded and output. When a sound field other than ACOUSTIC is selected: The sound source is processed with the sound field before being output. If the sound field genre is MOVIE (excluding MONO MOVIE sound field) or 3D, "PRO LOGIC" appears in the display and Dolby Pro Logic sound is decoded and output. When the ACOUSTIC sound field is selected or the sound field is turned off: The sound source is downmixed to 2 channels (L/R stereo) and output. When the ACOUSTIC sound field is selected, you can adjust the equalizer parameters (see page 21). The KARAOKE sound field reduces the level of the vocal component which is located at the center of 2-channel stereo sound. Since this sound field downmixes a 5channel Dolby Digital source to two channels and processes it in the same way, "DISCRETE" does not appear in KARAOKE mode. [. . . ] These channels manipulate the sound to be heard and enhance the action as it happens on the screen. To take advantage of Dolby Pro Logic, you should have at least one pair of rear speakers and/or one center speaker. You also need to select the appropriate center mode to enjoy a full effect. As you select higher levels, the room becomes "live, " and as you select lower levels, the room becomes "dead. [. . . ]
