THX SURROUND PREAMPLIFIER

STAGE ONE

UNPACKING

In-System Software Upgradable Design

WE WANT YOUR NEW PREAMPLIFIER TO LOOK AS GOOD AS IT DID LEAVING THE FACTORY. PLEASE CHECK PROMPTLY FOR TRANSIT DAMAGE.

Carefully unpack your new preamplifier. In extreme circumstances, items may have become damaged in transit. If any damage is discovered, notify the delivery service and/or dealer where the system was purchased. Make a request for inspection, and follow the instructions for evaluation. Be sure to keep the product with its original shipping carton and save your packing mate- rial to aid in future transportation.

As the world changes, the Stage One can change with it. Software upgrades can be delivered in the field via a back-panel RS-232 port. This enables us to make the Stage One compatible with new sources and to enhance its opera- tion without ever having to touch the hardware or even remove it from your system.

24-Bit A/D and D/A Converters

The Stage One uses identical, state-of-the-art, 24-bit Crystal Semiconductor digital-to-analog converters for all eight output channels. The stereo analog inputs, when not in Direct mode, are translated to digital with a 24-bit A/D converter.

STAGE ONE FEATURES

Latest Digital Decoding and Post-Processing

The Stage One uses advanced digital processing and 7.1-channel output capability to support all the latest surround-sound formats and decoding options, including Dolby Digital, DTS, THX Surround EX, DTS ES Discrete and Matrix, DTS Neo:6, and Dolby Pro Logic II. No matter what the source, the Stage One can select and apply the best decoding method automatically. And with its THX Ultra2 post-processing algorithms, the Stage One makes sure that the final sound is exactly what the director intended. In addition, it can apply its DSP power to multi-channel enhancement of ordinary stereo programs via its Party, Club, and 5-Channel Stereo modes. It even does mono!

Two-Channel Analog Preamplifier

The Stage One also includes an audiophile-quality two-channel analog pre- amplifier. Each analog input can be configured for Stereo Direct operation, which bypasses the analog-to-digital converters and the DSP module to guar- antee uncompromised reproduction of analog sources. Super Audio CD (SACD) and DVD-Audio players can be connected via their analog outputs to retain the full fidelity of these new formats.

Full Auto Format Selection

The Stage One will automatically determine the format of an incoming digital bitstream and switch itself to the appropriate processing mode. Separate level settings are available for each mode and are loaded automatically when a new mode is selected. This enables the system to be operated at the push of a button.

Analog Volume Control

The Stage One adjusts channel balance and overall volume in the analog domain to retain the full resolution of all signals.

Eight-Channel Analog Preamplifier

The Stage One provides an eight-channel analog input to allow direct connec- tion of DVD players with built-in decoders, such as those for DVD-Audio and SACD. A DB-25 connector is used. This input completely bypasses the digital processing module, allowing the Stage One to function as an eight-channel analog preamplifier. (See “Input Connections” for the DB-25 connector’s pin configuration).

Combination Digital and Analog Bass Management

The Stage One incorporates an advanced hybrid bass-management system that allows the preamp to preserve full dynamic range under all conditions. It performs high- and low-pass crossover filtering, as well as bass summing to the subwoofer, in the digital processor. This allows for more precise crossover filters. When there is no subwoofer, it routes low-frequency signals (including the LFE channel in Dolby Digital and DTS) to the system’s "Large" speakers in the analog domain. This method eliminates any need for digital-domain attenuation when these signals are combined. Processors that perform this function digitally (as most others do) must attenuate the signals being com- bined to avoid overload in the DSP module, resulting in a loss of dynamic range that can significantly impair sound quality.

Analog-Domain Dialog Normalization

Dolby Digital incorporates a function called Dialog Normalization, which was originally developed with HDTV in mind. It enables content providers to main- tain a constant average level for dialog at a given volume setting, regardless of the nature of the program. The idea is to enable you to switch from channel to channel on an HDTV set without ever having to lunge for the volume con- trol, all while not compromising dynamic range. Dolby requires that all Dolby Digital processors correctly respond to Dialog Normalization instructions in the bitstream. The Stage One has the ability to make the necessary adjustments in the analog domain. If this function were performed digitally, it could cause a loss of resolution.

THX ULTRA2 specifications

The Klipsch THX Ultra2 system is a premium home theater speaker system that epitomizes high-fidelity audio performance. Designed for enthusiasts seeking a cinematic experience in their own homes, this system excels in delivering powerful, clear sound across a wide frequency range.

One of the standout features of the THX Ultra2 system is its compliance with the THX Ultra2 certification. This certification ensures that the speakers meet rigorous performance standards, making them capable of delivering an immersive audio experience akin to that found in commercial theaters. The system is engineered to produce dynamic range and low-distortion sound at high volume levels, which is crucial for recreating the explosive effects of modern films.

The THX Ultra2 system typically comprises several key components: main speakers, satellite speakers, and subwoofers, all designed to work in harmony. The main speakers are equipped with Klipsch's signature horn-loaded technology, which allows for increased efficiency and better high-frequency response. This design means that listeners can enjoy crisp, clear dialogue and intricate details in music without strain, even at higher volume levels.

In addition to its horn-loaded design, the THX Ultra2 system includes high-performance woofers made from rigid materials. These woofers add depth and richness to the bass response, ensuring that explosions, music, and ambient sounds are felt as much as they're heard. The subwoofer is specifically designed to provide tight, impactful bass that extends down to lower frequencies, ensuring a full-range listening experience.

Klipsch also incorporates a unique technology called "Tractrix Horn," which enhances sound dispersion and efficiency. By directing the sound precisely toward the listener, this technology minimizes distortion and improves clarity, especially in larger rooms where sound can often dissipate.

Another notable characteristic of the THX Ultra2 system is its elegant design, which integrates seamlessly into any home decor. The speakers often feature a sleek finish that not only looks sophisticated but also minimizes resonance, further enhancing audio quality.

In conclusion, the Klipsch THX Ultra2 speaker system represents a pinnacle in home audio technology. With its THX certification, innovative speaker design, and superior performance across music and movies, it provides an unparalleled entertainment experience, making it a top choice for audiophiles and home theater enthusiasts alike. Whether you are watching movies or listening to your favorite albums, the Klipsch THX Ultra2 fully captures the essence of high-quality sound.
