Technology

Krell Current Mode

A proprietary Krell circuit topology in which the audio gain stages of a component operate in the current rather than the voltage domain. This unique technology pro- vides the component with exceptional speed and a wide bandwidth.

SACD Disc

A Super Audio Compact Disc (SACD) is an audio disc that provides exceptional high quality sound. Based on the new Direct Stream Digital (DSD) technology, a format that comprises a 1-bit system, a SACD has a sampling frequency 64 times higher than that of a conventional audio CD. With a frequency response of over 50 kHz, and a dynamic range of 120 dB over the entire audible spectrum, the results are spectacular: There is no better audio disc reproduction.

You will recognize a SACD by the super audio compact disc logo.

There are three SACD disc types:

1.A single layer disc consists of one high density (HD) layer.

2.A dual layer disc consists of two HD layers, and can store twice as much infor- mation as a single layer disc.

3.A hybrid disc consists of one standard compact disc layer with conventional two-channel audio compact disc information, and one HD layer.

SACD Disc: Hybrid Disc Type

Each SACD disc type may contain two areas of recorded information: a high-quali- ty two-channel area and a high-quality multi-channel area. Recorded information may vary per area. Refer to the disc inlay for more information.

The hybrid SACD disc type has the most versatile disc playback options, with two areas of recorded information for SACD playback as well as backward compatibili- ty with existing standard CD and DVD players via the standard compact disc layer.

On a hybrid SACD disc, the two layers are read from the same side of the disc. The HD layer is read by a DVD laser. The reflective conventional compact disc layer is read by the CD laser through the second, semi-transmissive HD layer.

CDDA

This is the digital audio file type utilized for standard CD’s. CDDA stands for a Compact Disc Digital Audio system.

Data Disc

This is a disc composed of digital audio files of a type other than CDDA. The most widely recognized non-CDDA digital audio file type is MP3.
