Casablanca IV

Music and Cinema Controller

Simply The Best

The Casablanca IV remains the finest sounding, most flexible preamplifier / processor available today even 18 years after its initial appearance in 1996. Continuous upgrades have maintained our vision of a reference-worthy multi-channel audio processor with audiophile performance, come-hither cosmetics and world-class usability and maintained essential contemporary features. The 2012 revision to the III HD brought a new, Dave Reich designed power supply with HDMI and lossless audio decoding. Today’s upgrade to the Casablanca IV brings 4k HDMI video pass-through (when upgrading a Casablanca I, II or III. The 4k HDMI card is an option when upgrading the Casablanca III HD), state-of-the-art audio bandwidth to 192 kHz, increases DSP processing power by a factor of 10, adds world-class digital room correction and optimization from Dirac Live operating at a world-leading 96 kHz and our novel Jitter Jail II to fix insidious timing errors especially inherent in HDMI audio signals. Only Theta Digital has offered such quality and long-term value in this ever-changing product category. Operational control is improved in the Casablanca IV. Not only can it be easily controlled by its front panel buttons, or via standard IR remote control, or, for the ultimate in system control, by its powerful RS-232 protocol which interfaces with complete home automation systems from companies such as Crestron, Savant and (soon) Control 4, remote operation is now possible from a new range of devices including iPad, iOS and Android devices.

Six Shooter Robot Analog Pre-Amplifier

How the Best Gets Better Theta’s solution for the purest transfer of analog signals from SACD and DVD Audio players, integrating with the digital signals processed in Casablanca III. Once a signal has been converted from digital to analog, it is vulnerable. In the SACD and DVD-A players currently available, the analog signal is subjected to enough abuse to negate most if not all of the sonic advantages of these theoretically superior formats. SACD and DVD-A routinely sends fragile analog signals through their digital processors –routed through inexpensive volume control chips, irradiate with radio frequency spuriae. Theta protects the analog signal by isolating it from Casablanca: Six Shooter is simply a fine straight-line analog preamplifier, controlled seamlessly by the Casablanca. The multi channel signal’s volume is controlled by individual metal film resistors, just like in the very best audiophile 2-channel preamplifiers. Expect the sonic transparency of analog preamplifiers, selling for $5,000 to $10,000. Since Six Shooter is controlled entirely from the Casablanca, and can be hidden away, we have not given it lavish cosmetics, and its simpler functionality allows for some savings; otherwise it would be in the same price range. Does everyone need such a component? Of course not. We all know that the sound from CD and DVD is good enough for most people. However, for those who demand the very best from their SACD and DVD-Audio, there is nothing else on a level with Six Shooter. Six Shooter at first glance might seem like an expensive switcher. However, this is a perfectionist piece at a realistic price once the quality is considered. For more specific information, along with diagrams showing connectors and illustrating signal paths, please see the technical addendum which is being added to the Casablanca manual. We think that every Casablanca owner who listens to multi-channel music will be interested in Six Shooter.
