Listening Room Calibration
Setting up your listening environment is a crucial element in enabling you to properly
evaluate content. Follow the procedures in this chapter carefully. You should only
need to do this once for each monitor system or room; however, quick checks are
advised before each session to confirm the correct calibration settings.
All the adjustments necessary to set up your listening room properly are found in the
Monitor Configuration
menu, which is on the main setup menu.
To set up your listening environment:
1. Assign the speaker configuration settings to match your system.
2. Set the delay values to adjust for speaker placement.
3. Calibrate the speaker playback levels.
4. Assign a level to the one-touch
Dim
setting.
5.1 Speaker Configuration Settings
Use the
Speaker Config
menu to configure the DP564 to match your listening
system. The settings for speaker size, subwoofer and crossover determine how the
DP564 distributes low frequencies to your speakers. Settings that match your system
allow the most accurate processing possible in your listening environment.
Large
indicates that the speaker is considered full-range, and does not require bass
management. A system with full-range speakers (setting:
Large
) at every output and
a subwoofer (setting:
Yes
) allows the system to process the signals for each channel
without any redirection. Setting a speaker to
Small
indicates that the speaker is a
near-field or satellite design and is not designed to reproduce extremely low
frequencies (typically, below 80 Hz). The
Small
setting filters out low-frequency
information from that channel and redirects it to a speaker more capable of
reproducing low frequencies (often a subwoofer).
Subwoofer Crossover
The setting you choose for the subwoofer crossover frequency (
SW Xover Freq
)
depends on the capability of your front and surround speakers. The DP564 diverts
signals below the value of this setting from those channels, set as
Small
in the
Speaker Configuration
menu, to either the subwoofer output (in nearly all
cases) or to the Left and Right outputs. Most smaller speakers require a setting of
