User manual DENON AVR-2801@AVR-981

[. . . ] Keep the set free from moisture, water, and dust. The ventilation should not be impeded by covering the ventilation openings with items, such as newspapers, table-cloths, curtains, etc. No naked flame sources, such as lighted candles, should be placed on the apparatus. No objects filled with liquids, such as vases, shall be placed on the apparatus. [. . . ] The pre-out output (including the speaker output) is automatically turned off when headphones are connected. NOTE: To prevent hearing loss, do not raise the volume level excessively when using headphones. Use this to turn off the audio output temporarily. IN jacks are output directly to the front (left and right), center, surround (left and right) speaker systems without passing through the surround circuitry. [4] Combining the currently playing sound with the desired image Simulcast playback Use this switch to monitor a video source other than the audio source. In play modes other than the external input mode, the signals connected to EXT. In addition, signals cannot be output from channels not connected to the input jacks. The external input mode can be set for any input source. To watch video while listening to sound, select the input source to which the video signal is connected, then set this mode. IN), the play mode (DIRECT, STEREO, DOLBY/DTS SURROUND, 5CH/6CH STEREO or DSP SIMULATION) cannot be selected. Playing one source while recording another (REC OUT mode) With "RECOUT SOURCE" displayed, turn the FUNCTION knob to select the source you wish to record. select "OFF" or "ON". Dimension Control: This control gradually adjust the soundfield either towards the front or towards the rear. The control can be set in 7 steps from 0 to 6. Center Width Control: This control adjust the center image so it may be heard only from the center speaker; only from the left/right speakers as a phontom image; or from all three front speakers to varying degrees. The control can be set in 8 steps from 0 to 7. 2) The center image parameter for adjusting the expansion of the center channel in the DTS NEO:6 MUSIC mode has been added. To perform this operation from the remote control unit, check that the mode selector switch is set to "AUDIO". Dolby Digital mode (only with digital input) and DTS Surround (only with digital input) When performing this operation from the main unit's panel, press the SURROUND MODE button, then turn the SELECT knob and select Dolby Pro Logic or DTS NEO:6. The level can be adjusted in units of 1 dB from ­10 to 0 dB. Set to the desired level according to the speaker systems being used and the source to be played. To reset the settings to the factory defaults, use the display "Yes". [. . . ] Decoding is performed with emphasis on separation performance to achieve the same atmosphere with 2-channel sources as with 6. This mode is effective for playing sources recorded in conventional surround formats as well, because the in-phase component is assigned mainly to the center channel (C) and the reversed phase component to the surround (SL, SR and SB channels). The front channel (FL and FR) signals bypass the decoder and are played directly so there is no loss of sound quality, and the effect of the surround signals output from the center (C) and surround (SL, SR and SB) channels add a natural sense of expansion to the sound field.
