The top left-hand corner of the display indicates the Stage One’s current decoding mode or the post-processing being applied to a two-channel input signal. The following decoding and post-processing modes are available in the Stage One: Dolby Digital, DTS, Stereo, Pro Logic II, 5-Channel Stereo, DTS Neo:6, Club, Party, and Mono.

Dolby Digital and DTS bitstreams can contain anywhere from 1.0 to 6.1 chan- nels of information. (The ".1" indicates the presence or absence of a low-fre- quency effects, or LFE, channel.) If the bitstream contains between 1.0 and

5.1channels of information, the number will display to the right of the decod- ing mode.

1.0

This indicates a mono signal. This signal is reproduced through the center channel if a center speaker is present. Otherwise, it will be reproduced equally through the left and right front output channels. If a center speaker is present, you can force the signal to be routed to the left and right front channels by pressing the Stereo button on the remote control.

This indicates that a two-channel signal is present. It will be reproduced through the left and right front output channels. Two-channel signals can also be modified by any of the Stage One’s post-processing modes. The post-processing function will be indicated in the bottom left-hand portion of the front-panel display.

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 THX Ultra2 system typically comprises several key components: main speakers, satellite speakers, and subwoofers, all designed to work in harmony.

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.
