Basic checks of site and installation.
Before you begin making settings and adjustments to your DFP-3000 system, it’s best to confirm some basic conditions.
Here is a check list.
3.1 Check that the Decoder environment is suitable.
The DFP-D3000 Decoder is intended to be mounted in a rack chassis along with other cinema equipment. However, it
should not be mounted in close proximity to power amplifiers or other equipment which may radiate strong magnetic fields
or which give off high heat. Observe the ambient temperature limit of 40
°
C (104
°
F) and if the interior of the rack is
excessively warm, provide more ventilation to lower the temperature.
n
Do not “hot plug” the Reader! The Reader gets its power through the cable that connects it to the Decoder. Do not
remove or install this cable while the Decoder AC power is on. Doing so may cause damage to the Reader and void its
warranty.
3.2 Confirm basic power up activity.
Connect the Reader to the Decoder using its cable. Note that this special cable cannot be cut or spliced. Connect the line
cord to a mains supply of 100-240 VAC 50/60 Hz and connect the backup power supply to a mains supply for which it is
rated. The LED in the SELECT switch will be illuminated Red. Switch on the Decoder. The SELECT switch LED will go
out, the LCD display will be illuminated, the MASTER LEVEL numerical display will go through a brief count and then
display its last
+/_ dB setting. The illuminated PRESET switch shows the last and current Preset selected and the LCD
display shows its name and any fallback Preset that is assigned to it.
3.3 Confirm the proper version of Decoder firmware.
The instructions contained in this Guide relate to functions and features associated with DFP-D3000 firmware versions
v2.74 and higher. See TN99121401 for the latest versions of all forms of firmware and software for Sony cinema products.
The following steps illustrate how to display the DFP-D3000 firmware version on the front panel LCD screen:
