Operating Your P/DD-1500 Digital Surround Decoder
Refer to Figure #2
Front Panel and Remote and Controls
You can control all of the operations of the P/DD-1500 with either its front panel controls or hand held
remote. The remote control gives you complete access to the functions of both your P/SP-1500 and
P/DD-1500. These same keys include On, Off, and input selection. Refer to the P/SP-1500 owner's
manual for more details about using the remote control to operate your P/SP-1500. Other keys on the
remote dedicated to the P/SP-1500 will not affect the P/DD-1500 and pressing any mode other than 5.1
will always disengage the P/DD-1500. Also note that the only on-screen display that applies to the
P/DD-1500 is 5.1 mode indicator. Therefore, you will need to refer to the front panel of the P/DD-1500
for its control status.
Input Selectors
You can select the RF and three digital inputs from the remote control or on the front panel. When you
choose an input, a corresponding green LED on the front panel will illuminate to indicate which input
you selected. Note that the four AV Inputs on the P/SP-1500 correspond automatically to the inputs on
the P/DD-1500: (RF = Video 1, Toslink = Video 2, Coax 1 = Video 3, Coax 2 = Video 4). If you want to
select different "non corresponding" inputs for the P/DD-1500 and P/SP-1500, use the input selector
buttons on the front panels instead of the remote control.
P/DD-1500 Processing Modes
You can select three different processing modes from the remote control or on the front panel. When you
first turn the unit on and before your digital source is playing, the green LED above the Dolby Digital
button and all the 
L, C, R, LS, RS, LFE
 
channel indicators  in the front panel display will light to show
you that all six channels are ready to receive a signal. Once the P/DD-1500 receives a signal, the 
L
OCK
indicator in the display will illuminate. The P/DD-1500 detects whether the material was recorded in 5.1
or 2 channel and select it automatically:
Dolby Digital
If the source you are playing was encoded in 5.1 channel Dolby Digital, the internal decoder
automatically selects Dolby Digital processing. The green LED above the Dolby Digital button and all
of the amber 
L, C, R, LS, RS, LFE
 channel indicators  will illuminate to indicate 5.1 channel Dolby
Digital processing.
Pro Logic Surround
If the source material you want to listen to was encoded in Dolby Surround (L
T
,
 R
matrix) you can
decode the signal into Dolby Pro Logic by selecting this mode. You can also use this mode to listen to
standard two channel material to obtain surround effects that, while not Dolby Pro Logic, may still be
quite enjoyable. When you select this mode, the 
L, C, R
 indicators will light amber, the 
LS
 
and 
RS
indicators will light red to indicate standard Pro Logic mono surround channels, and the 
LFE
 
indicator
will stay off. If the program material has been encoded in 5.1 channel Dolby Digital, the Pro Logic mode
will not operate because the P/DD-1500 will automatically select the Dolby Digital mode.
Two Channel
This mode instructs the decoding circuitry to automatically route or "downmix" the center, left and right
surround channels to the front left and right channels for two channel stereo playback. In this mode, the
P/DD-1500 operates much like a two channel D to A converter such as the Parasound D/AC-1100 HD.
Even if the source material has been encoded in Dolby Surround or 2 channel Dolby Digital, the
P/DD-1500 will playback the material in stereo. As a result, only the front left, right and subwoofer
channels are active in this mode and only the amber 
L
 
and 
indicators will light. You can select the two
channel stereo mode from the remote control or on the front panel.
