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’s 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.

Panorama
Extends the front stereo image to include the surround
speakers for an exciting “wraparound” effect with side-wall
imaging.
Center Width Control
With Pro Logic decoding, dominant center signals can come
only from the center speaker. If no center speaker is present,
the decoder splits the center signals equally to the left and
right speakers to create a “phantom” center image. The
Center Width control allows variable adjustment of the
center image so it may be heard only from the center
speaker; only from the left/right speakers as a phantom
image; or from all three front speakers to varying degrees.
It’s recommended to set the control to use the position 3
values for the Music mode. This will also help distinguish the
Music mode from the Movie mode, which automatically
presets the Center-width control to position 0.
