Yamaha RX-N600 Owner's Manual

What really creates the rich, full tones of a live instrument are the multiple reflections from the walls of the room. In 
addition to making the sound live, these reflections enable us to tell where the player is situated as well as the size and 
shape of the room in which we are sitting.

■

There are two distinct types of sound reflections that combine to make up the sound field in addition to the direct sound 
coming straight to our ears from the player’s instrument.

Reflected sounds reach our ears extremely rapidly (50 ms to 100 ms after the direct sound), after reflecting from one 
surface only (for example, from a wall or the ceiling). Early reflections actually add clarity to the direct sound.

These are caused by reflections from more than one surface (for example, from the walls, and the ceiling) so numerous 
that they merge together to form a continuous sonic afterglow. They are non-directional and lessen the clarity of the direct 
sound.

Direct sound, early reflections and subsequent reverberations taken together help us to determine the subjective size and 
shape of the room, and it is this information that the digital sound field processor reproduces in order to create sound 
fields.

If you could create the appropriate early reflections and subsequent reverberations in your listening room, you would be 
able to create your own listening environment. The acoustics in your room could be changed to those of a concert hall, a 
dance floor, or a room with virtually any size at all. This ability to create sound fields at will is exactly what YAMAHA 
has done with the digital sound field processor.

• Choose a sound field program based on your listening preference, not merely on the name of the program.
• When you select an input source, this unit automatically selects the last sound field program used with the corresponding input source.
• Sound field programs cannot be selected when the component connected to the MULTI CH INPUT jacks is selected as the input 

source (see page 38).

• Sampling frequencies higher than 48 kHz (except for DTS 96/24 signals) are sampled down to 48 kHz and then sound field programs 

are applied.

■

The name of the selected sound field program appears in 
the front panel display and in the OSD.
