AUX inputs.
If either of the two 8-wide balanced AUX inputs are used for sources other than cinema processors, take
note that the sophisticated automatic fallback system of the DFP-3000 requires these inputs to be enabled
by a logic command to make them active. To use AUX1 or AUX2 for external sound sources other than
digital film sound decoders, short Pin 34 (AUX1 DATA OK) or Pin 35 (AUX2 DATA OK) to GROUND
on the Automation connector to enable the AUX1 or AUX2 inputs. See Tech Note TN99042801. Another
approach is to chose No Fallback (
*) as the fallback option for an AUX Preset, which prevents fallback
and so forces the AUX input to play whenever it is selected.
Headphones and HI output.
A single D-Sub 9 pin connector provides a L/R stereo headphone output from the back panel. This is a
parallel of the front panel headphone jack and is affected by the MONITOR SELECT switch and HEAD-
PHONES level control. This connector also has two pins providing MONO outputs, which can be used to
feed most Hearing Impaired transmission systems. Signal level for the HI outputs can be calibrated by an
adjustment control located inside the Decoder. Detailed instructions for Hearing Impaired output level
adjustment is discussed in Section 6.15 of this Guide.
Automation inputs and outputs.
All automation logic inputs and outputs are brought to a single 37-pin D-Sub connector on the DFP-
D3000. For a complete description of the connections available, see Tech Note TN99042801. Other Tech
Notes describe specific means of connecting to other types of cinema equipment; see Tech Note
TN99070701.
RS-232C connector.
This 9-pin female D-Sub connector is used to connect an external PC-compatible computer using a null-
modem cable.
RS-422 connector.
Contact your Sony service or sales representative for details on the use of this connector.
Remote level control.
Remote control of the Master Volume is possible by connecting a 100k-ohm linear taper potentiometer.
The wiring convention of this potentiometer is unique to Sony, so follow the documentation in the
Appendix carefully.
Bypass (backup) power supply.
The DFP-D3000 is provided with an external DC power supply which provides emergency power to
bypass components within the Decoder. This power supply allows the Decoder to continue playing
optical tracks in the event its main power has been turned off. Check that this power supply has the
correct AC mains voltage rating for your country and is connected to the AC mains and to the back of the
Decoder. A small red LED in the SELECT switch on the front panel of the Decoder indicates when the
unit is being powered only by the backup power supply.
