AUX input

The 8 channel AUX input can be used and configured in many ways. Here are some

examples:

•

It can be used as a straight bypass input for the audio coming from the central

cinema processor, such as the Sony DCP-1000 or a cinema sound processor of a

different make. If the central cinema processor is of recent design, technology and

quality, the AUX input can be configured so that the DFP-2500 B-chain is bypassed.

The master level control will still be active.

•

It can be used to process the audio from a central cinema processor with a B-chain

of inferior audio quality, which is then bypassed. Instead the DFP-2500 B-chain

takes care of channel level trim, channel EQ and master level control.

•

It can be used to process the audio from an external audio source, such as an

electronic cinema playback device. All B-chain processes will then be done in the

DFP-D2500

Automation inputs and outputs. All automation logic inputs and outputs are brought

to a 37-pin D-Sub connector on the DFP-D2500

RS-232C connector. This 9-pin female D-Sub connector is used to connect an external

PC-compatible computer for set-up and alignment using a null-modem cable.

RS-422 connector. This 9-pin female D-Sub connector is used to connect an external

automation system to the DFP-D2500. This makes it possible to control all the main

operation functions of the DFP-D2500. Contact Sony for details about the protocol 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 carefully.
