3.4 Check the version of the Setup Software on your computer.
The Setup Software is updated frequently. Be sure you are using the latest version, which will be v2.00,
build 2.055 or higher. You can check the SDDS web site or contact Sony Cinema Products to determine
the latest version and to request a free copy. You can check the version of Setup Software you are using
by launching the program and selecting Help>About. . . from the pull down menu at the top of the main
screen.
3.5 Confirm a proper chassis earth ground.
Most audio grounding schemes require that the chassis of the DFP-D3000 have a solid electrical connec-
tion to the rack in which it is mounted. The finish on the rack mounting rails may be very durable. Make
sure that the mounting screws cut through the finish of the DFP-D3000 and that the mounting ears make
electrical connection through the rack rails’ finish to the rack itself. Test this with an ohm meter. Addi-
tionally, a screw terminal Technical Ground is available on the back panel of the Decoder, to help make a
solid ground connection. Do not remove the line cord safety ground pin in an attempt to avoid ground
loops. This precaution is already taken care of in the design of the DFP-D3000 and removing the pin will
have no benefit, but doing so will compromise electrical safety and may violate electrical codes.
3.6 Check the optical input connector wiring.
Make sure that the optical input connector is wired according to the pinout diagram in the Appendix. Use
individually shielded twisted pair cable. See Chapter 5, A-Chain Alignment, for information regarding the
optical pre-amp test points. Note that the wiring of this connector may not correspond to that of other
cinema processors.
3.7 Confirm proper audio interface wiring.
The Sony DFP-D3000 Decoder unit uses professionally balanced audio interface connectors, pinned
according to the THX convention, for interconnections to amplifiers, crossovers, limiters, booth monitors,
and other cinema processors. Unfortunately, many such devices do not employ balanced inputs or
outputs. It is essential that proper balanced to unbalanced interface wiring techniques are used when
connecting to these devices so as to ensure optimum operating conditions for the DFP-D3000 and con-
nected equipment. Failure to use proper techniques in your sound rack wiring may result in reduced
system headroom, improper theatre calibration, and compromised sound performance. For a guide to
properly interconnecting balanced and unbalanced audio signals, refer to Tech Note TN99060401.
