Dolby Laboratories CP65 - Manual (Page 15)

2-9
CP65-300
In a CP65-300 (when Cat. No. 300 modules are fitted in place of the normal Cat. No. 350
modules) J16 and J18 should be rotated so that the words “Format 42” appears the right
way up. With J24 in the “NR” position input signals will be A-type decoded when the
Mag/Aux format is selected. With J24 in the “NO NR” position signals pass through the
noise reduction modules but the processing will be turned off. If both of these processing
options are required frequently an external switch may be connected to J24.
NOTE: To play 70mm Dolby Stereo (Format 42) with a CP65-300, the left, center, right,
and surround outputs of the magnetic pre-amp must be connected to TB6 and the Le
and Re outputs must be connected to TB4. If changing between an optical format and
mag format 42 is required, external switching
may be added (or J16 must be manually
rotated to the Format 22 position for optical playback and to Format 42 for 70mm
playback).
