3.2 Check the version of the Setup Software on your computer.
The Setup Software is updated regularly. Be sure you are using the latest version,
which will be v3.00, build 3.000 or higher. You can check the SDDS web site at
http://www.sdds.com
and to request a free copy. You can check the version of Setup Software you are
currently using by launching the program and selecting Help>About. . . from the pull
down menus at the top of the main screen.
3.3 Confirm proper audio interface wiring.
The Sony DFP-D2500 Decoder unit uses professionally balanced audio interface
connectors, pinned according to the THX
crossovers, limiters, booth monitors, and other cinema processors. Unfortunately,
many such devices may not employ balanced inputs or outputs. It is essential that
proper balanced to unbalanced interface wiring techniques are used when connecting to
these devices to ensure optimum operating conditions for the DFP-D2500 and
connected equipment. Failure to use proper techniques in your sound rack wiring may
result in reduced system headroom, improper theater calibration, and compromised
sound performance. For a guide to properly interconnecting balanced and unbalanced
audio signals, refer to Tech Note TN99060401.
3.4 Chassis earth ground check.
Most audio grounding schemes require that the chassis of the DFP-D2500 have a solid
electrical connection 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-D2500 and that the mounting ears make electrical connection through the rack
rails' finish to the rack itself. Test this with an ohm meter. Additionally, 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-D2500 and removing the pin will have no benefit, but doing so will compromise
electrical safety and may violate electrical codes.
