9.8.8 Adjustments of Audio System
Details of the connections and adjustments of the audio system are provided in “Connections of the Audio
System”. Below, the adjustment methods are described.
Of the DFP-D3000 audio output, the Surround Left output and Surround Right output will be connected
to the Surround input of the SA-10. Currently, as the EQ setting cannot be changed for each preset in the
DFP-D3000, when combining it with the Surround EX processor, adjust the level with the equalizer of
the surround channel at the Surround EX processor side. In other words, perform B-chain adjustments
using the Surround EX processor for the surround channels.
For the Surround EX processor, if the level of signals input to the surround processor is not adjusted
properly, the designated surround effects cannot be obtained. For this reason, there is a need to adjust the
level of signals sent to the Surround EX processor from the SDDS.
The following describes the procedures for setting the level of the signal output from the DFP-D3000 to
the Surround EX processor, and the equalizer.
Equipment required
. Personal computer installing the DFP-D3000 setup software
. Interlink cables (cross cables and all pins must be cross connected)
. Audio level meter (or AC voltmeter)
Adjusting/setting procedures and measurements
1. Connect the DFP-D3000 and personal computer using interlink cables. When using a commercially
available interlink cable, as male D-Sub 9 pin connectors are provided at the two ends of the cable, it
is necessary to change only the DFP-D3000 side to the female connector. In this case, use a commer-
cially available polarity converter connector (gender changer) to convert the connector shape. As the
DFP-D300 uses mm screws (ISO standard) for fixing the connector (side secured by the screws),
when using cables for the PC, the adjustment/setting/measurement can be done more easier if the
fixing screws at the connecting side of the cable to the PC is removed.
2. Turn on the power of the DFP-D3000 and Surround EX processor. Turn the power of the power
amplifier until level adjustments complete.
