3. Site preparation and interconnection.
Before you begin making settings and adjustments to your DFP-2500 system, it is best
to confirm some basic conditions. Here is a check list.
3.1 Decide audio signal path
Configuring the DFP-D2500 as an output device
The DFP-D2500 has been primarily designed to be the last link of the audio processing
chain before the crossover networks and power amplifiers (in order to facilitate the full
st
8 channel output capability), very much like the 1 generation SDDS processor, the
DFP-D2000. Only by using the DFP-D2500 in this manner will you obtain the full benefit
of the D2500, such as its 8 channel capability, its exceptional B-chain performance, its
seamless fallback transitions, and the capability to enhance the performance of the
existing cinema processor to today's state-of-the-art audio processing.
The illustration below shows this recommended signal path. No automation connections
are needed.
Configuring the DFP-D2500 as an input device
If for some reason the above configuration is not possible, the DFP-D2500 can also be
used as an input device to the central cinema processor. The System Output of the DFP-
D2500 is then routed to the auxiliary input of the existing cinema processor.
Additionally, automation lines need to be connected to allow the DFP-D2500 to switch
the central cinema processor in and out of the applicable SDDS preset, depending on
the SDDS Playback Status. The necessary logic signals have been integrated into the
