About Su nd Sound
There are three basic sound effects that produce the
acoustics of concert halls and movie theater. Direct sound,
early reflection, and reverberation. The acoustic quality of a
room depends on how that room reproduces these three
sounds.
Types of sounds
Early reflection
Reverberation
Notes
* The DSP mode remains while the power is turned off.
* Noise may occur when switching the DSP modes and Effect levels.
* When using the DSP mode, large outputs from the player may cause
distortion from your amplifier.
In this case, change the LINE OUT connections from FIXED to VARIABLE so
that you can adjust the output level with the PHONE LEVEL/LINE OUT
LEVEL control.
© When connecting with DIGITAL OUT, you cannot use the OSP mode
function.
