[. . . ] THETA DIGITAL C O R P O R A T I O N Casa Nova Owner's Manual Digital Done Right TM PREFACE CONGRATULATIONS You have just acquired the most advanced component for the control and processing of audio and video ever to have been developed. IMPORTANT Save all packaging in a dry place away from fire hazards. Your Casa Nova is a precision electronic instrument and should be properly packaged any time shipment is made. In the unlikely event that you have to return your Casa Nova to the factory for service, or if you send it to us for updating, the original packaging will best protect the unit from shipping damage. In order to achieve the fullest flexibility and enjoyment from your Casa Nova, we at Theta recommend that you read this manual in full before connecting the unit to your audio/video system.

NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC rules. [. . . ] Acoustically, this means that if the sound sources are in proper time-alignment, a smoother frequency response will be realized at the listening position. The Linkwitz-Riley crossover is only applicable to slopes of 12 and 24 dB/octave. A proper Linkwitz-Riley crossover with a 12dB slope should have the low pass portion inverted. This is done internally in the Casa Nova. A note on crossovers Casa Nova's complement of crossover options can at first appear daunting. Most surround sound processors offer a simple selection to set their crossovers: Speaker Small or Speaker Large. When set to small, normally a 12dB/octave Butterworth crossover is performed at 80Hz. Occasionally, it is a 24 dB/octave slope. This simple setting does not take into account the huge variations in speaker design and room acoustics and more often than not results in non-optimum performance. We have endeavored to offer this rich set of options with the aim of superior performance. With this in mind, following are a few simple suggestions to make this process easier. A note on home theater There are a few common misconceptions about home theater and bass reproduction. Chief among them is that the ". 1" or "LFE" channel normally contains most or all of the bass information. The LFE channel contains sound effects such as explosions, rumbling and the like. All other channels (left, center, right, left surround, right surround) may contain an equal amount of bass, and often do. Their bass, however, tends to be more related to the soundtrack, vocal material or localized sources such as a drum beating behind the listener. This is important information to understand when setting up crossovers in the coming section. Another misconception is that the center channel is "fill" and is minor in importance. The center channel contains the lion's share of important information (particularly dialog) in the cinematic experience. It is therefore critical that the center speaker be of the highest quality possible and special attention be given to its mounting and positioning. *** 23 Left/Right Speaker Configuration The left/right configuration section contains the sub menus shown in figure 23. Figure 23 - Menu Map of SETUP/INP Page 1/CONFIG/LT/RT In the SETUP/INP/CONFIG submenu (figure 21), press button # 5 and select the desired crossover type. Then press button # 1 to set up the front left/right speakers.
