About The Dolby CP45
The Dolby Model CP45 combines the high performance for which all processors
manufactured by Dolby Laboratories are well known with a new cost-effective
integrated design. The CP45 is the heart of your theatre sound system. All
sound sources are connected to the CP45 which processes their signals
appropriately and feeds them to the power amplifiers.
The CP45 precisely complements the techniques used in the preparation of
Dolby Stereo optical releases. By providing a stereo optical preamp with
precise slit-loss correction, professional Dolby A-type noise reduction and
Dolby Spectral Recording, an advanced 2:4-channel decoder, and multi-band
screen speaker equalization, the CP45 ensures accurate reproduction of Dolby
A-type and SR releases. It has also been designed for convenient interface with
theatre automation systems.
Among the standard features of the CP45 are a built-in fader with remote and
mute facilities; simple push-button soundtrack format selection; and
comprehensive fail-safe features that include a built-in bypass system.
The following sound formats are supported:
Format Number
Mono 01
Dolby Stereo A-type 04
Dolby Stereo SR 05
Non sync 1 60
Non Sync 2 / Aux 61
