Hall Surround
This is another exclusive Yamaha surround sound
processing mode, designed to recreate a large concert ha!
sound field effect. It is identical to the Natural Surround
mode, with the addition of delay circuitry. This adds an
extra dimension of depth and imaging which simulates that
of a large; spacious concert hall, and is appropriate for
music sources.
Note: f a monaural sound source is used when in the
Dolby Surround, Natural Surround, or Hall Surround modes,

monaural audio sources, such as video and TV programs. it
creates a surround sound effect, and employs a delay
circuit for an extra dimension of depth and imaging.
Delay Time Control
The Delay Time control is effective with those three modes
employing a delay circuit: Simulated Surround, Hall
Surround, and Dolby Surround. It provides continuously
variable control over delay time, from 10 to 30 milliseconds.
The center upright position is a normal delay time setting,
however experimenting with different delay settings wil have
considerable effect on each surround mode. By applying
extra or less delay, sound effects, background noise, and
ambient noise coming at you from the rear speakers can be
enhanced or subdued for extra effect. Adding too much
delay will cause an unnatural effect with some sources.
Experiment with the Delay Time control to created an effect
