OPERATING INSTRUCTIONS
A. NORMAL OPERATION
1. Initial Power-Up
Each time the CP45 is connected to power, it automatically sets itself to
the format it was in when power was removed unless the power has
been removed for more than a week. Under these circumstances the
wake-up state is:
• Format 01 Mono
• Front-panel (Local) fader activated
• Proj 1 or Proj 2 LED illuminated, indicating the externally-
selected projector that is active (Proj 1 can be set to be selected
automatically if no external selection has been made although it
is usual for the individual projectors to be selected for bypass
mode flexibility).
2. Format Selection
Select the desired film soundtrack format or your non-sync source by
pressing the appropriate button. The LED in the button illuminates to
confirm that the format was selected. The formats are as follows:
• 01 Mono: for all optical prints of any vintage with conventional
mono optical (“Academy”) soundtracks.
• 04 Dolby A-type: for Dolby Stereo releases, except those marked
SR or Digital.
• 05 Dolby SR: for releases marked as having a Dolby SR
soundtrack. (If your CP45 is not equipped with the SR circuit
needed to play SR copies, 04 Dolby A-type can be selected.)
• 60 Non-sync 1: for your music tape or CD player.
• 61 Aux/Non-sync 2: this format may be programmed in a number
of different ways depending on the optional equipment fitted and
the installation. Possible options include:
Magnetic soundtracks from projectors or followers with
appropriate magnetic preamplifiers.
Extra sound sources (consult your service engineer for details).
