INTRODUCTION
Welcome to a new world of possibilities. Casablanca III is by far the most advanced surround sound
processor/home theater controller available today. It offers the advantages of Theta’s legendary mastery in
digital signal processing and sound quality unapproachable by any other equipment.
Getting to know your Casablanca III
Despite Casablanca III’s great technical sophistication, we believe in making it as easy as possible for you to
use. We think you’ll enjoy the intuitive way the Casablanca III works. Rather than offer a frustrating
bewilderment of little used functions in constant view, vying for your attention, Casablanca III is structured
systematically by function.
The “user interface” is based on simple logic. For example, when a function button is pressed, you can
make changes within its menu(s) and press the same function button again to exit that function. (The same
button that got you in gets you back out).
This Casablanca III has been put through a rigorous and unique testing procedure that insures that it will last
for many years with minimal service requirements. This procedure includes the following:
•All assembled circuit boards are given a thorough visual inspection and are then tested in a bench-
reference Casablanca III.
•The tested assembled circuit boards are then installed in a new Casablanca III and the whole unit is
tested for every function and parameter.
•The unit is put on a burn-in torture rack for 100 hours to test for any possible component failures.
•The Casablanca III is tested on an audio analyzer for all pertinent parameters.
•The Casablanca III is put through a final bench test wherein every possible feature, mode and
parameter is checked.
•The unit has all remaining chassis components installed and then undergoes a complete visual
inspection, which assures that all Casablanca III’s meet visual specifications.
•The unit is then put through a critical listening test.
Burn In Time
This unit has a break in period of about 1 week during which continuous improvement in sound quality will be
observed. It is recommended that music be played continuously through the unit during this time to expedite
the break in period.

IMPORTANT NOTICE
I. Due to the computer-based circuitry used in Theta products, it is imperative that the Casablanca III
be connected to a ground via its three wire AC power cord. It is important that the AC power outlet,
which the Casablanca III is plugged into, is actually grounded. Failure to do so will severely
compromise the performance, reliability and safety of use of the Casablanca III.
II. It is also important to prevent contact with static electricity when connecting other components and
cables to the Casablanca III. When connecting cables, simply place one hand on top of the
Casablanca III and then grasp the metal “barrel” of the cable with the other hand and plug (unplug)
the cable into (from) the appropriate jack on the Casablanca III.
III. The Casablanca III, as with all electronic equipment, is susceptible to static discharges. Resetting
the unit may be required if anomalies occur after receiving a static discharge. In this case, put the
unit in standby and turn off the rear panel power switch for 2 minutes, and then turn it on again.
IV. Ventilation is an important issue when placing the Casablanca III in a system. Make certain that the
Casablanca III is placed in a well-ventilated area or rack unit.
V. Please take note that some powerline conditioners defeat the AC power ground on their outlets. If
the intention is to plug the Casablanca III into a line conditioner, check with your dealer to make
certain that the particular conditioner that is intended for use DOES NOT DEFEAT THE AC
GROUND on its AC outlets.
VI. DO NOT remove any cover panels from the Casablanca III, as there are no user serviceable
components inside. Refer servicing and updating to qualified service personnel only.
VII. Should the Casablanca III need to be reset, it must be put in standby first via the front panel power
button. Then the rear panel power switch is to be turned off for at least 2 minutes.
VIII. The Casablanca III can be susceptible to excessive RF. End caps in all unused inputs will improve
the sound quality and may reduce the susceptibility to RF induced anomalies.
Reference Manual Conventions
For clarity purposes, references to buttons, LED’s and display parameters will be shown in bold capital
letters.
All functions to be performed from, and in reference to the front panel of the Casablanca III will be found in
the front section of this manual, whereas all functions to be performed using the hand held remote and/or
viewed on a video monitor will be found in the back, or last part of this manual.

Glossary of Terms and Abbreviations
TERM DEFINITION
AES/EBU (Audio Engineering Society) / (European
Broadcasters Union) A three wire balanced digital audio standard. This interface uses a 3-pin XLR type connector and allows for data communication between digital
audio equipment.
Analog-to-Digital Converter A device that converts analog signals into a digital format. Once
encoded, all audio is stored or processed as a series of numbers rather
than as the audio itself.
Balanced Audio Signals Signals that are carried on three-conductor cables, with two of the
conductors carrying the same signal 180° out of phase and the third as
ground. Balanced connections usually cost more than unbalanced
connections, but are less susceptible to picking up hum and prevent
interference with low-level signals.
Center Spread A proprietary Theta Digital process whereby the front center speaker
signal can be incrementally spread evenly between the front left and right
speakers.
dB Decibel, a relative unit of loudness.
Dolby 3 Stereo The Dolby 3 Stereo mode reproduces sound using only the 3 front
channels, and is intended to be used either before surround speakers are
installed, or for programs that might benefit from deriving a center
channel output, but where the quality of the surround output is
unsatisfactory.
Digital-to-Analog Converter A device that converts digital signals into an analog format.
Hz (Hertz) A unit of frequency.
IR Infrared. A method of wireless transmission of data.
LFE Low Frequency Effect. Commonly a discrete audio track designated for a
sub woofer.
mS Millisecond, or 1\1000 of a second.
Oversampling The process of taking more samples than is required in order to more
accurately reconstruct a digitized signal for playback in the analog
domain.
Phantom Center Mode The Phantom setting for the center speaker redirects the center channel
signal equally to the front left and right outputs, thus creating an illusion of
a center speaker. This mode is intended to be used when no center
speaker is present.
Phantom Surround Mode The Phantom setting for the surround speakers is intended to be used
when no surround speakers are present in the system. With this setting
active, the surround information is added to the front channels. If the
current mode is Dolby Pro Logic, the Casablanca III will automatically
decode in Dolby 3 Stereo.
Sampling Rate The rate at which an analog (real world) signal is converted into digital
numeric values.
S/PDIF Interface (Sony/Phillips Digital Interface
format) A digital audio interconnection standard, developed jointly by Sony and Phillips.
TRS Tip, Ring, Sleeve. Names of the 3 connecting elements of a stereo phono
jack or plug.
Unbalanced Audio Signals (AKA single-ended) Signals that are carried on two-conductor cables, one “hot”, or signal, and
one ground.
Xover Abbreviation for the word ‘Crossover’.
