Casablanca processor models can be updated to a Casablanca V. This means that units originally released from 1996 onward can now be updated to today’s standards. The Casablanca continues to be made in America. Each Casablanca is individually made to order and fully tested in the USA.

Theta proprietary switched resistor network in the analog domain.

All DSP processing is 24bit with 56 bit accumulator. Some processes, such as low pass crossovers, are 48bit with 56 bit results.

Channels Supported: Left, Right, Center, Left Surround, Right Surround, Center Surround, Left Front Sub, Right Front Sub, Left Surround Sub, Right surround Sub, Center Sub, Left Side, Right Side.

Modes: Matrix, Special Matrix, Dolby Pro Logic, Dolby Digital, DTS, Stereo, Mono, Analog Direct, Analog Matrix, Circle Surround (optional).

Post Processes (applied in addition to selected mode): Stereo Front/Rear, Party, Center Spread.

EQ: Four levels of high frequency roll-off (shelf-type) to compensate for overly bright sources.

Crossovers: Separate crossovers for each of the following: Front Left/Right, Front Center, Surround Left/Right, Surround Center. Three types supported: Linkwitz-Riley, Butterworth, Phase Perfect. Crossover frequencies: 40Hz, 50Hz, 63Hz, 80Hz, 125Hz, 160Hz. Crossover slopes: 6dB, 12dB, 18dB, 24dB per octave. Butterworth crossovers have separate adjustments for high and low pass.

Subwoofers: Up to five subwoofers supported. 1- single subwoofer, 2- left/right subwoofers, 2- front/rear subwoofers, 3- left/right/surround subwoofers, 4- left/right/surround left/surround right subwoofers, 5- left/center/right/surround left/surround right subwoofers. Each subwoofer can be set to receive a full range signal in case the sub has an internal crossover that cannot be defeated.

LFE: Phase adjustment (0, 180 degrees), level adjustment (0dB to -30dB, off)

Delays: Master (applies to all channels) delay for syncing with video processors, comprehensive separate delay settings for all speakers including subwoofers.

D/A Conversion: 24-bit Ladder (8x oversampling – 4x @96K). Two DACs per channel (8 per board) for true differential operation.

Volume Control: Theta proprietary switched resistor network in the analog domain.
Digital Filter: 8x oversampling (4x @ 96K) Theta proprietary FIR filter running on Motorola 56362 DSP. Single-Ended Output: None
Sample Rates Supported: 32KHz, 44.1 KHz, 48 KHz, 88.1 KHz, 96 KHz.
