Theta Digital, long acclaimed as America’s most advanced manufacturer of high-end digital audio and video products, introduces the Casablanca III Music and Cinema Controller.

Central to Casablanca III is Theta’s classic Open Architecture. As in earlier Casablanca models, the processor’s motherboard provides for all signal routing, while various daughter boards carry function-specific circuitry.

This design philosophy, which Theta pioneered in the original Casablanca, allows installers to configure and upgrade the Casablanca to meet the personal needs of each owner. The upgrade will also allow the Theta design team to more quickly implement future software upgrades and enhancements.

In the Casablanca III, the open-architecture component takes customization to a new level, providing literally hundreds of crossover choices (including phase-perfect and Linkwitz-Riley) that facilitate the Casablanca’s exquisite ability to be tailored to specific environments and speaker set-ups.

Six Shooter

The Six Shooter is an external preamp/analog switcher that allows the 6 analog output channels of an SACD or DVDA player to integrate with the Casablanca III. There are 3 inputs and one output on the Six Shooter. The first two inputs are designed to receive 6 channels of analog SACD or DVDA signal. The third input receives the first 6 output channels from the Casablanca III (L/R/C/LS/RS/S1). The output of the Six Shooter is connected to the amplifier inputs.

The first two inputs of the Six Shooter contain high-quality analog volume controls. The volume for these two inputs is controlled by the Casablanca III. Volume for the third input (first 6 channels of the Casablanca III) is done in the Casablanca.
