What is stereo?




There are now two system of high fidelity, monophonic (monaural) and stereophonic. Monophonic is a system that starts from one microphone and is fed through a single high fidelity set. Stereophonic is a double system. Two separate microphones are placed at different sides of the orchestra and two different systems are used to keep the two signals or channels separated. Two separate speakers are used, placed on different sides of you room. Stereo is much like 3-D photography, two slightly different sound reach your ears giving you a new dimension in sound.

Krell CD-DSP


Integrated Compact Disc player The Krell CD-DSP is the first integrated compact disc player to combine an updateable software-based processor with a high-end CD transport. The processor and transport are coupled to extremely flexibleinput and output  sections, creating a product of unique function and value. Audiophiles can now gain the advanced performance capabilities of separate components in a single unit.

Software-based Processing
The CD-DSP processor uses a 16 times oversampling version of our Waveform Duplicator software, which is run on a Motorola DSP-56001 digital signal processor. The extraordinary resolution of fine detail and accuracy of waveform reconstruction achieved is not possible by other methods. The processor output is routed to a Class A balanced analog output stage. The result is a sonic quality distinguished by robust dynamic impact, extended frequency response and three dimensional imaging.

The Waveform Duplicator software is loaded into socket-mounted Eprom chips to allow inexpensive software updates in the future .

Transport and Operational Features
The CD-DSP is built around the CDM-1 MK II Philips finest transport for CD player applications system absorbs extraneous vibrations that might interfere with data recovery from the disc.
The CD-DSP is destined to become the digital heart of any audio system. Three inputs and two outputs provide connection to other sources in the digital domain. Two analog outputs allow the CD-DSP to drive independent systems.
Whether you are considering yout first CD player or the replacement of an existing unit, the CD-DSP is your invitation to the future.
