■ Parameters for adjusting reverberant sound
Reverb Time
Reverb Time parameter adjusts the attenuation time of the 
rear reverberant sound based on the time that about 1kHz 
reverberant sound takes for 60dB of attenuation. 
Reverberant sound attenuates faster as you decrease the 
value. Reverb Time adjustment allows you to create a 
natural reverberant sound, by setting the attenuation time 
longer for a sound source or room with less echo, or 
shorter for a sound source or room with more echo.
Reverb Delay
Reverb Delay parameter adjusts the time difference 
between the beginning of the direct sound and the 
beginning of the reverberation sound. The larger the value, 
the later the reverberation sound begins. Increasing the 
value of Reverb Delay allows you to create a reverberant 
sound in a wider area for the same Reverb Time.
Reverb Level
Reverb Level parameter adjusts the reverberation sound 
level. Increasing the value of Reverb Level makes the 
reverbration sound level higher, which allows you to 
create more echo.
■ Parameter for MOVIE sound field programs
Decode Type
Selects the decoder type for use with the MOVIE sound 
field programs.
Note
• You cannot select a decoder for the following MOVIE sound field 
programs.
– Mono Movie
– Sports
– Action Game
– Roleplaying Game
■ Parameter for 2ch Stereo
Direct
Automatically bypasses the DSP circuit and tone control 
circuit when an analog sound source is selected as the 
input source. You can enjoy a higher quality sound.
■ Parameters for 7ch Stereo
Center Level / Surround L Level / Surround R 
Level / Surround Back Level / Presence L Level / 
Presence R Level
Adjusts the volume of the center, surround L/R, surround 
back and presence L/R channels in the 7ch Stereo 
program. The available parameters differ depending on the 
setting of the speakers.
