Cat. No. 791 Digital Crossover Card

Print-friendly version 

The Dolby Cat. No. 791 upgrades your Dolby CP650 to a model CP650XO, the most comprehensive cinema processor available.

Two- or three-way screen speakers can provide added audio impact in your cinema. The Cat. No. 791 card integrates digital speaker crossover networks into your CP650, eliminating the need for a separate crossover unit.

The Cat. No. 791 card offers many other advantages as well:

Convenience

The CP650 B-chain and crossover alignment procedure is tightly integrated into a single software application, making setup and alignment quick and easy via a laptop PC or the CP650’s front-panel screen. Logical and easy-to-understand commands take you through the whole procedure. Presets are included for many popular loudspeakers, to further speed you through the process.

Flexibility

Every alignment parameter is right at your fingertips and all adjustments are made in real time. An onscreen spectrum analyzer gives you instant feedback on alignment effects. Independent channel-level settings enable perfect level matching of each crossover region. The card provides full-range audio outputs for Le and Re when using full-range or two-way mode.

Quality

All audio outputs are differential (balanced) for each frequency band (low/mid/high) to reduce the possibility of ground loops from cables connecting the CP650 to the power amplifiers. All of the audio processing is in the digital domain to ensure the highest possible performance. Additional specific strengths include the interactive choice of filter type, slope, upper and lower cutoff frequencies, and time alignment delay.

Highlighted above is the crossover alignment section of the CP650 Setup software. Having the ability to easily switch between alignment screens offers time-saving convenience to the overall CP650 setup.

Note: You can order a Cat. No. 791 digital crossover card for an existing CP650 that was manufactured after July 2002, or a CP650 that contains at least the “A” revision of the Cat. No. 772 and Cat. No. 774 cards. A Cat. No. 790 must be installed in the CP650 in order to add the Cat. No. 791. For completely new installations, the model CP650XO includes the Cat. No. 791. For complete information, call your Dolby^® distributor.
