Using the DSP Modes

This unit provides a variety of DSP (Digital Signal Processor) modes. The stored basic settings and adjustments
performed on the Setup and Adjustment Menus (see pages 35 to 50) are applied.
• The following operations are only possible when the receiver is ready for Zone 1 operations, and are used only
for the Zone 1 sources.

Reproducing the Sound Field

The sound heard in a concert hall, club, etc. consists of direct sound
and indirect sound—early reflections and reflections from behind.
Direct sounds reach the listener directly without any reflection. On
the other hand, indirect sounds are delayed by the distances of the
ceiling and walls. These direct sounds and indirect sounds are the
most important elements of the acoustic surround effects.
The DSP modes can create these important elements, and give you a
real "being there" feeling.

LARGE HALL 2 : Reproduces the spatial feeling of a large
vineyard-shaped hall designed primarily for
classical concerts. (Its seating capacity is
about 2000.)
RECITAL HALL : Reproduces the spatial feeling of a small hall
designed primarily for classical recitals.
(Seating capacity is about 500.)
OPERA HOUSE : Reproduces the spatial feeling of an opera
house with a high ceiling and multi-level
seating layout.
CHURCH : Reproduces the spatial feeling of a majestic
church with a high ceiling.
LIVE CLUB : Reproduces the spatial feeling of a live music
club with a low ceiling.
DANCE CLUB : Reproduces the spatial feeling of a rocking
dance club.
