Compared with previousDolby surround, Dolby Digital provides even better sound quality,greater spatial accuracy, and improved dynamic range.NoteAlthough a full set of speakers (front left, right, and center, surround leftand right, and a subwoofer) is required for true 5.1 channel Dolby Digitalsurround sound, this receiver lets you enjoy Dolby Digital (and DolbySurround) program sources, even if you connect only the front speakers.* LFE = Low Frequency Effects. This channel delivers separate non-directional bass signals to the subwoofer for more dynamic deep basssound effects.Although only Dolby Digital soundtracks incorporate a separate lowfrequency channel, connecting a subwoofer will also improve deep bassperformance in the other surround modes.The indication “LFE” appears in the display when a signal is being inputfor this channel.Front speaker (L, R)Subwoofer (SW)*Center speakerSurround speakers (L, R)DTSThe DTS multi-channel audio format is available on CD, LD and DVDsoftware. DTS is a strictly digital format and can not be decoded insidemost CD, LD or DVD players. For this reason, if you attempt to listen toDTS encoded software through the analog output of your new CD, LDor DVD player, you will experience digital noise in most cases. This noisecan be quite loud if the analog output is connected directly to a highpower amplification system. Proper measures for playing the digitaloutput as described below should be taken to avoid this situation. Toenjoy DTS Digital Surround playback, an external 5.1 channel DTSDigital Surround decoder system or an amplifier with a built-in DTSDigital Surround decoder must be connected to the digital output (S/PDIF, AES/EBU or TosLink) of a CD, LD or DVD player.All models are incorporated with the DTS decoder.* Optional in this mode.* LFE = Low Frequency Effects.
