Customizing the Nº502 Mark Levinson
L7 Music Surround (Logic 7 Music Surround)
This Surround mode is designed for enhanced playback of 2-channel
stereo or multi-channel music sources recorded in real spaces and for
playback of recordings that contain added reverb. The L7 Music Surround
mode enhances the listening experience by extracting ambient sounds
from the input source and sending these sounds to all speakers. Since the
ambient sounds are heard from all directions, it creates a realistic playback
presentation that simulates what listeners experience in real spaces.
We recommend using this mode for classical music scores, since classical
music presentations are typically recorded in real spaces with additional
reverb to enhance the stereo mix.
Dolby Pro Logic
®
The Dolby Pro Logic
®
modes are specifically designed for playback of
Dolby Surround-encoded sources. The Nº502 supports all extensions of
the Pro Logic surround mode family.
An extension of the Dolby Pro Logic matrix technology, Dolby PLIIx
dynamically creates a 7.1-channel sound field from matrix surround,
2-channel stereo, or 5.1-channel digital sources when your system is
configured for surround back speakers. Dolby PLII is available for systems
configured for 5.1-channel surround sound.
Note The Nº502 handles Dolby EX encoding differently. Refer to the “Audio
Profiles” section found earlier in this chapter for more details.
