[. . . ] THETA DIGITAL C O R P O R A T I O N Casa Nova Step-by-Step Setup Guide Digital Done Right TM Casa Nova Setup Procedure Flowchart 2 Step by Step Speaker Configuration Casa Nova contains a comprehensive set of speaker configuration settings. These settings are believed to be the most complete ever offered in a home theater component and should allow any speaker to perform optimally regardless of speaker type. It is important to bear in mind that the following procedure is merely a guideline and that room acoustics, speaker design/quality, music/film type, and personal preference all have a part in these settings. Please note that the menu and parameter names described herein are the ones shown on the front panel LCD and not the OSD (On Screen Display). [. . . ] 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 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. The subwoofer Full Range/Crossover setting has no effect in this case. Note: You will now be directed to set up crossovers as if a sub is present. There are some general rules that the Casa Nova follows in the special case of no subwoofers: Case 1 - The front left/right configuration setting is FULL: Any speaker set that is set to "crossover" will have its low pass signal sent to the left/right channels. Case 2 - The front left/right configuration setting is XOVER or FUL/LP: Any speaker that is set to crossover will lose its low pass signal. 4) Determine if the subwoofer needs to be sent a crossed over signal or a full range signal: a) Defeat the subwoofer's internal crossover and set SUB to XOVER. The crossovers in the Casa Nova have been engineered to be superior to any analog crossover, regardless of quality. b) If the sub woofers internal crossover cannot be defeated set the SUB to FULL. Again, it is preferable that the subwoofer's crossover be defeated and that the Casa Nova control all crossovers. It is 5 recommended that the subwoofer manufacturer be contacted to see if there is a possible modification to the subwoofer to defeat its crossover. c) If the sub woofer is to be sent a full range signal, set the crossover frequency on the sub's internal crossover to match that of the speaker set that is crossed over in the Casa Nova. [. . . ] A setting of 0 turns on the LFE and sets its level in proper proportion to the remaining 5 channels. Setting the LFE at ­10 [dB] may be desired for late night viewing or if source material may overpower the sub woofer. Setting the LFE to OFF may be useful for late night viewing, however, please note that any information in the . 1 channel will be lost. 7 Go to the second page of the Dolby Digital setup submenu Set the center speaker delay to the same value as in the SETUP/INP/DLYS submenu.
