ABOUT THE L70’S SURROUND MODES

The L70 receiver offers nine distinct SURROUND MODEs, tailored for different types of recordings or program material. The table below lists which modes are available to what input signals.

With a two-channel (STEREO) source the following SURROUND MODEs can be selected:

•Dolby PRO LOGIC II MOVIE

•Dolby PRO LOGIC II MUSIC

•Dolby PRO LOGIC II EMULATION

Two-channel recordings, whether stereo or surround-encoded, are reproduced with ProLogic II surround processing, yielding output to left-, centre-, and right-front channels, discrete left/right surround channels, and subwoofer (assuming these are present in the current <SPEAKER CONFIGURATION>).

NOTE

ProLogic II is a more recent evolution of the original Dolby ProLogic surround processing that yields more stable imaging and full bandwidth sound to the rear channels in Movie mode, offering sound that is more similar to Dolby Digital decoding.

The L70 provides three Pro Logic II variations: MOVIES, MUSIC and EMULATION. See “Adjusting

SURROUND MODES”.

EARS

Two-channel recordings, whether stereo or surround-encoded, are reproduced with proprietary NAD surround processing with signals output to the left, centre-, and right-front channels and discrete left/right surround channels, plus subwoofer (assuming these are present in the current <SPEAKER CONFIGURATION>). EARS extracts the natural ambience present in nearly all well produced stereo recordings. It does not synthesize any ambience or other sonic elements and thus remains truer to the sound of the original musical performance than most other music-surround options.

Select EARS for listening to stereo music recordings and broadcasts. EARS produces a subtle but highly natural and believable ambience from nearly all “natural-acoustic” stereo recordings; typically, these include classical, jazz, and folk genres as well as numerous examples from others. It’s virtues include a realistic, stable “front-stage” sonic imaging and spacious but unexaggerated ambient “virtual acoustics” that remain faithful to the original recording.

ENHANCED STEREO

All recordings reproduced in stereo (Downmix, from Dolby Digital/DTS multichannel sources) are reproduced via the maximum speaker complement configured in the current <SPEAKER CONFIGURATION>). Enhanced-Stereo can be useful for maximum volume from all channels, or for multi- speaker background music (cocktail party) listening.

STEREO

All recordings reproduced in stereo (Stereo, or Downmix, from Dolby Digital/DTS multichannel sources) are reproduced via the front speakers only (plus subwoofer, if any). Stereo can prove useful in certain late- night or very low-volume listening situations.

The following Surround Sound Modes require a specially encoded signal that must be present in digital format to be decoded by the L70. These modes are automatically switched on when the appropriate data stream is detected. The desired data stream must sometimes be selected in the setup menu of the source media.
