5、el Input Indicators:These indicators are multipurpose,indicating either the speaker type selected for each channel or the incoming data-signal configuration.The left,cen- ter,right,right surround and left surround speaker indicators are composed of three boxes,while the subwoofer is a single box.The

6、 center box lights when a “Small”speaker is selected,and the two outer boxes light when “Large”speakers are selected.When none of the boxes are lit for the center,surround or subwoofer channels,no speaker has been selected for that position.(See page 16 for more information on configuring speakers.)

7、 The letters inside each of the center boxes display active input channels.For standard analog inputs,only the L and R will light,indicat- ing a stereo input.When a digital source is play- ing,the indicators will light to display the chan- nels begin received at the digital input.When the letters fl

8、ash,the digital input has been interrupt- ed.(See page 20 for more information on the Channel Indicators).

43、undtracks that are recorded with matrix surround, by creating separate center, rear left and rear right signals. while the Pro Logic II Music mode should be used with musical selections that are recorded with matrix surround or even with normal stereo mode, creating separate rear left and rear right

44、 signals in any case. The Pro Logic II mode creates compelling five-channel surround sound from conventional stereo recordings. Logic 7 CinemaExclusive to Harman Kardon for AV receivers, Logic 7 is an advanced mode that extracts the Logic 7 Musicmaximum surround information from either surround-enco

Depending on the number of speakers in use and the selection made in the SURROUND SELECTmenu, the “5.1” versions of Logic 7 modes are available when the 5.1 option is chosen, while the “7.1” versions of Logic 7 produce a full sound field p

46、resentation, including back surround speakers when the “6.1/7.1” option is chosen.The Logic 7 C (or Cinema) mode should be used with any source that contains Dolby Surround or similar matrix encoding. Logic 7 C delivers increased center-channel intelligibility, and more accurate placement of sounds

47、with fades and pans that are much smoother and more realistic than with former decoding techniques.The Logic 7 M or Music mode should be used with analog or PCM stereo sources. Logic 7 M enhances the listening experience by presenting a wider front soundstage and greater rear ambience. Both Logic 7

48、modes also direct low-frequency information to the subwoofer (if installed and configured) to deliver maximum bass impact.The Logic 7 E (or Enhance) mode is an extension of the Logic 7 modes that is primarily used with musical programs and is available with the 5.1 surround mode option selected only

49、. Logic 7 E adds additional bass enhancement that circulates low frequencies in the 40Hz to 120Hz range to the front and surround speakers to deliver a less localized soundstage that appears broader and wider than when the subwoofer is the sole source of bass energy. DTS 96/24 DTS 96/24 is a high-resolution format that uses a 96kHz sampling rate with 24 bits to produce extended information that improves the harmonics of the source material.
