Distance between the surround speakers and the listener must be
shorter
than
or equal
to that
between the front speakers and the listener.
In case the channel delay settings cannot match your speaker configuration, please set all
distances to the same and use your receiver/amplifier to set the channel delay.
NOTE
The front, surround and surround back speakers are configured as pairs. Changes to the
distance of one speaker will automatically change the other speaker of the pair.
3.
Trim Level
: The speaker trim level parameters sets the volume of each individual channel.
Channel trim is generally not required since most A/V receivers have the capability to adjust
channel trim and compensate for speaker sensitivity differences. However, if your receiver does not
have such functions (many receivers do not support channel trim for their multi-channel analog
inputs), you may adjust channel trim through the player. For most accurate results, it is
recommended that you use test tones from a calibration disc, such as
AIX Records Audio
Calibration Disc and HD Music Sampler
or
Digital Video Essentials HD Basics
, and a SPL (Sound
Pressure Level) meter. The trim level can be set to +/- 10dB in 0.5dB increments.
Other Audio Processing Settings
In addition to
Speaker Configuration, Dynamic Range Control
is another audio processing setting
that can be configured:
1.
Dynamic Range Control
: To set the Dynamic Range Compression (DRC). DRC can smooth out
the sonic peaks and valleys common with wide-range digital audio. Enabling DRC may make low
level audio more audible during low-level listening. Turning off DRC restores the sonic energy
present in the original recording. The available options are:
•
Auto
– Play at the dynamic range specified by the disc. This option applies to Blu-ray
Discs only. For other disc types no dynamic range compression is applied.
•
On
– Turn on dynamic range compression.
•
Off
– Turn off dynamic range compression.
