6. Setting up Preset configurations.
A Preset is a set of retained DFP-D2500 Decoder settings that apply to a particular input
signal. These settings are associated with the two preset buttons on the front panel,
namely SDDS and AUX.
If the bypass button is pressed, none of these preset configuration settings or
B-chain processes are carried out.
The following parameters are stored in the DFP-D2500 for these two presets:
Speaker output matrix
Fallback preset (for SDDS only)
Preset trim (fader offset for each Preset)
EQ/Channel level trim On/Off switch
Surround delay On/Off switch
Surround delay
Sub-woofer low pass filter frequency
To change these parameters, access the Preset Configuration screen from the
Preset Configuration option under the Presets item in the main screen menu bar.
To re-configure a Preset, select the candidate Preset from the list of preset
configurations in the Preset Selection area of the screen. After selecting the Preset,
the various fields in the Preset Configuration area will change to reflect its current
configuration

Matrix edit box and select from the list that pops up. This list automatically contains
only those matrix formats that are allowed for the type of input signal that you have
chosen. Here are all the matrix modes and their meanings:
