INTRODUCTION

Welcome to a new world of possibilities. Casablanca 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

Despite Casablanca’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 works. Rather than offer a frustrating
bewilderment of little used functions in constant view, vying for your attention, Casablanca 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 store the changes and exit that
function. (The same button that got you in gets you back out). Also, when in a function menu or sub-menu,
other features and functions will not be accessible, as they have no direct relation to the function being edited.

This Casablanca 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.

• The tested assembled circuit boards are then installed in a new Casablanca 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 is tested on an audio analyzer for all pertinent parameters.

• The Casablanca 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’s meet visual specifications.

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.

1

IMPORTANT NOTICE

I. Due to the computer-based circuitry used in Theta products, it is imperative that the Casablanca be

connected to a ground via its three wire AC power cord. It is important that the AC power outlet,
which the Casablanca is plugged into, is actually grounded. Failure to do so will severely
compromise the performance, reliability and safety of use of the Casablanca.

II. It is also important to prevent contact with static electricity when connecting other components and

cables to the Casablanca. When connecting cables, simply place one hand on top of the
Casablanca 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. The Casablanca, 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 1 minute, then turn it on again.

IV. Ventilation is an important issue when placing the Casablanca in a system. Make certain that the

Casablanca 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 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, as there are no user serviceable

components inside. Refer servicing and updating to qualified service personnel only.

VII. The Casablanca can be susceptible to excessive RF. Shorting plugs 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 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.

Some devices such as LD players feature both analog and digital audio outputs. To avoid rewiring the LD
player outputs to the Casablanca inputs when changing between laser disks with analog only audio tracks, it
is advisable to connect both the analog and digital outputs of the LD player, if featured, to both the

Priority Switching

The Casablanca’s inputs can support virtually every digital audio data format used in today’s technology.
Since it is most unlikely that one input number will require more than one digital format, some of the input
jacks share the same input channel number. For example, an AES/EBU (balanced) XLR, a glass optical, a
TosLink, and an RCA jack are all assigned to input # 1.

If a digital signal were present at more than one input jack with the same input channel assigned to it, the
Casablanca will automatically select one of them according to a pre-determined priority, since two input
signals cannot share the same channel. This is called

Each input channel has different input jacks assigned to it, as indicated by the channel number next to each
digital input on the rear panel. Table 2 shows the entire priority switching scheme.
