Distance
You can specify the distance (changing the sound delay) between
speakers (front, center and surround speakers) and the listener for
optimal stereo sound.
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.
Volume
You can make fine adjustment to the loudness of each speaker from -
10 to +10 dB. When this option is selected, a test noise will
generate automatically from each speaker, one by one. To go to the
next speaker manually, press .
Adjust loudness by pressing
and press OK to
confirm setting and exit the menu.
Pro Logic II Mode
The additional flexibility of Pro Logic II allows it to be tailored for specific
applications. Five standard modes are available:
Pro Logic - it offers users the robust surround processing of the original
Pro Logic.
Virtual
- it’s usually used when Pro Logic II is connected to a virtual
process for speaker use.
Music
- it’s recommended as the standard mode for autosound music
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
mono surround 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”.
Pro Logic II Control
PL II Control lets you to customize the Pro Logic II Music Mode Sound
Effect. The option is available only when the player is in Music Mode.
Dimension
A simple control that alters the ratio of L+R to L-R for the two-
channel input signals. It allows the user to gradually adjust the
soundfield either towards the front or towards the rear. If a
recording is too spacious or strong from the surrounds, it can be
adjusted “forward” to get a better balance. Likewise, if a stereo
recording is somewhat too “mono” or “narrow” sounding, it can be
adjusted toward the rear to get a more enveloping, immersing
result.
