DOLBY® HEADPHONE
Dolby Headphone technology, compatible with any pair of conventional headphones, accurately simulates
the experience of hearing a 5.1-channel speaker system properly set up in a listening room, minus the
annoying “listener fatigue” effect that plagues other headphone-based virtual surround sound offerings.
Dolby Headphone technology is ideal for private playback of multi-channel entertainment without
disturbing others nearby.
Dolby Headphone models the sound of a playback system into three different listening environments,
based on acoustic measurements of real rooms:
DH1 is a small, well-damped room appropriate for both movies and music-only recordings. This decoding
process is known as the Dolby Headphone “Reference Room”
DH2 is a more acoustically live room suited to music listening, but also great for movies.
DH3 is a larger room, more like a concert hall or movie theatre.
ADJUSTING SURROUND MODES
Use the HTR L73 remote’s “Surr. Mode” key, or the front panel SURROUND MODE key, to select the
SURROUND MODE you wish to display and listen to; this will display on the L73’s VFL Display. One can also
select variations using the HTR L73 cursor keys on the <SURROUND:> line of the OSD. Use the
HTR L73’s and cursor keys to navigate among and modify that mode’s adjustable parameters
(if any).
NOTE
SURROUND MODE parameter changes are not maintained when you change SURROUND MODEs.
