The default distance is 10 feet for front and center speakers and 5 feet for surround speakers. Change the distance from 1 to 30 feet according to your actual listening environment by pressing

and then OK.

You can make fine adjustment to the loudness of each speaker from -

10to +10 dB. When this option is selected, a test noise will

generate automatically from each speaker, one by one. To go to the

Pro Logic II Mode

 

Pro Logic

 

 

 

The additional flexibility of Pro Logic II allows it to be tailored for specific

 

 

 

 

 

 

applications. Five standard modes are available:

 

Virtual

 

 

 

 

 

 

 

 

Pro Logic - it offers users the robust surround processing of the original

 

 

 

 

Music

 

 

 

 

Pro Logic.

 

 

 

 

 

 

 

Virtual

- it’s usually used when Pro Logic II is connected to a virtual

 

Movie

 

 

 

 

process for speaker use.

 

 

 

 

 

 

 

Music

- it’s recommended as the standard mode for autosound music

 

Matrix

 

 

 

 

systems (without video), and is optional for A/V systems.

 

 

 

 

 

 

 

 

 

 

 

Movie

- It can be called simply “Pro Logic II”. It has stereo surround

 

 

 

 

channels and no surround filter, unlike Pro Logic which has a

 

 

 

 

monosurround channels and a 7KHz surround filter. Movie

 

 

 

 

mode is the standard required for all A/V systems.

 

 

 

Matrix

- It the same as the Music mode except that the directional

 

 

 

 

enhancement logic is turned off. It may be used to enhance

 

 

 

 

mono signals by making them seem “larger”.
