1. Introduction
1.1 About the DFP-2500
The Sony DFP-D2500 Film Sound Decoder has been designed to upgrade existing
cinema sound systems to SDDS in a simple and cost effective way, whether your
auditorium sound system supports 5.1, or the full 8 channel SDDS sound format.
The DFP-D2500 must be combined with a DFP-R3000 Film Sound Reader, which reads
the SDDS data on film and sends this bit-stream to the DFP-D2500 for SDDS decoding
and audio processing. The audio processing includes complete 8 channel B-chain
functions and a calibrated master level control, both using high-power DSP (Digital
Signal Processing) for maximum sound quality, reliability and consistency.
The output of the DFP-D2500 is then routed directly to the main crossover networks and
power amplifiers (alternate configuration of the DFP-D2500 is also possible – see
section 3.1, Configuring the DFP-D2500 as an Input Device).
Additionally, the DFP-D2500 can apply its powerful DSP-based sound processing to the
current system's cinema processor, vastly improving the sound performance of existing,
or aging equipment. For example, if the existing cinema processor in the sound system
is not of current design and technology, the D2500's input can be configured so that the
superior B-chain and master level control of the D2500 is applied instead. This
effectively upgrades the sound performance of the existing cinema processor to today's
state-of-the-art technology and capability, at a much more reasonable cost than
discarding and replacing it with a new, higher-priced cinema processor.
