Listening Mode Setup
Description listening mode parameters
Subwoofer Set this to �Off� if you are not using a subwoofer (even if one is connected). If �No� is selected for the Subwoofer setting in the Speaker Config sub-menu, then this setting will not appear. Re-EQ/Academy Depending on the listening mode, you can either turn ReEQ on or off, or you can select �Re-EQ,� �Academy,� or �Off.� Re-EQ: Re-EQ (re-equalization) takes the edginess or �brightness� out of your home cinema sound to compensate for the fact that sound mixed for theaters may sound too bright when played back through speakers in the home environment. Academy: Older monaural film mixes relied on highfrequency rolloff in presentation to sound properly balanced, so that excessive hiss from the grain structure of the film would not be heard. The highfrequency loss was typically due to a combination of optical slit loss, electrical filters, loudspeaker response, and screen loss. Some films have been transferred to video without such a high-frequency rolloff, and thus sound overly bright and hissy. This unit includes this �Academy filter,� which is based on contemporary playback practices for such films over wide-range systems. On: Select to turn on the Re-EQ. Off: Select to turn off both the Re-EQ and Academy filters. Input Channel This allows you to set which input channel to use for monaural sound. Auto L+R: Select this under normal circumstances. When the input source is center channel only, this channel is used for monaural sound input channel. Otherwise, left and right channels are mixed and the mixed signal is used for monaural sound input channel. Left/Right: You will need to select either left or right when playing a video source that contains bilingual data. In such a case, the left and right channels will contain different language. Select the channel with the language you desire. Output Channel This allows you to set which output channel to use for monaural sound. If �None� is selected for the Center Speaker setting in the Speaker Config sub-menu, then this setting will not appear. Auto L+R: The monaural sound is split between the left and right channels. Center: The monaural sound is output from the front center channel. Surround Speakers This setting allows you to decide through which speakers to output the sound meant for the surround speakers during 5.1-channel output when seven speakers are connected to this unit. Note: If you have two surround back speakers placed very close together and you select �Surround Back� or �Surr L/ R+Back,� then you may not achieve the desired left-right separation of the sound space. In this case, �Surround L+R� is recommended. Surround L/R: This outputs the sound to the surround left and right speakers as normal and outputs nothing to the surround back left and right speakers. Surround Back: This outputs the sound to the surround back left and right speakers and outputs nothing to the surround left and right speakers. Sur L/R+Back: This outputs the sound to both the surround left and right speakers and the surround back left and right speakers. Upsampling Upsampling processes the input digital signal or the converted digital signal from analog input source and converts their digital sampling frequency to twice the current frequency for an even further detailed sound reproduction. This can be set to either �On� or �Off.� Surround Mode Selects the Surround Mode for analog or PCM source. Available options are PL�Movie (Pro Logic�Movie), PL� Music (Pro Logic�Music), DTS Neo:6 Cinema, and DTS Neo:6 Music. You can change the Surround Mode settings easily using the remote controller. When you set the listening mode to Pro Logic�or DTS Neo:6, each press of the SURROUND button on the remote controller cyclically changes the Surround mode in the order of PL� Movie, PL�Music, DTS Neo:6 Cinema, and DTS Neo:6 Music. Surround Mode (2ch) Selects the Surround Mode for 2 ch digital source (except for PCM). Available options are PL�Movie and PL� Music. You cannot select Neo:6 Cinema and Neo:6 Music. Pro Logic�Music Panorama Use this listening mode to expand sound space in front of a listener to both side of the listener. On: Turns on the PL�Music Panorama mode. Off: Turns off the PL�Music Panorama mode. Pro Logic�Music Dimension Use this listening mode to modify the sound space location forward or backward. The setting of �3� is the normal position and setting to �2� or lower moves the sound space forward and setting to �4� or higher move the sound space backward. If the stereo recording has excessive broadness or too strong surroundness, move the sound space forward to get the appropriate sound balance. In contrast, if the stereo recording is somewhat felt like monaural or has narrowness, move the sound space backward to get more surroundness. Pro Logic�Music Center Width In Pro Logic�decoding, outstanding center signal will be output only from center speaker. When the center speaker is not used, the decoder divide the center signal equally to each front left and right speakers to create �phantom� center sound image. The Pro Logic�Music Center Width mode allows you to adjust where the center sound image is heard from. Depending on your setting, the center sound image will be heard from center speaker only, front left and right speakers (as phantom center sound image), or all three speakers (center, front left and right) in various level combinations. For home use, applying some �width� to center signal will improve the level balance for center and main speakers, and effect the width of the center sound image, or �mass� of the sound. Many of sound recordings processed for stereo playback will be reproduced better by controlling the parameter for this listening mode. The recommended setting for Pro Logic� Music mode is �3.� This allows you to easily distinguish the Pro Logic�Music mode from the Pro Logic�Movie mode whose setting is automatically set to �0.�
