9.6 Connecting the CP-500 and DFP-3000
When constructing the system by combining the Dolby Laboratories CP-500 and DFP-D3000, as both are
equipped with analog pickup interfaces and system control terminals, the functions of both equipments
will clash.
It is therefore important to decide which to master depending on ease of constructing the system and uses
by the customer. This document describes both the connection when using the DFP-D3000 as the master
and the connection when using the CP-500 as the master.
9.6.1 Connecting the DFP-D3000 to the CP-500 with the DFP-D3000 as the master
The advantage of this connection is that the merits of the DFP-D3000 such as high sound quality equaliz-
er circuit and digital signal switching can be put to full use.
The disadvantages on the other hand are; because the CP-500 is unable to output SR-D format OK/NG
switching signals at the voltage level, the Fallback control circuit of the DFP-D3000 cannot be used as it
is. The same effects can be obtained by using an optional board (cat. 684 card) outputting pulses and
performing preset switching of the DFP-D3000 according to the preset switching of the CP-500.
In this case, connect the analog track (PEC) and input from the cinema processor other than the CP-500 to
the DFP-D3000, and also connect Fallback if necessary. This means that the CP-500 side is dedicated to
playback in the SR-D format.
In this case, the following restrictions apply to both the DFP-D3000 and CP-500.
DFP-D300: Firmware version 2.60 and higher
CP-500:
CP-500 units with firmware v1.51 or higher and control board Cat. 684 is installed.
If the software of the DFP-D3000 or CP-500 is older than the above, contact a Dolby Laboratories dealer
for the CP-500 and a Sony service center for the DFP-D3000 to upgrade the firmware to the latest
version.
