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.

Mission PCM II

 The PCMII was designed utilizing the Cyrus digital and analogue know-how and was built to the same exacting standards as all Mission-Cyrus products.  Of paramount consideration in the design and manufacture of a compact disc player is the integrity and sufficiency of the power supply section as well as the accuracy and consistency of the digital to analogue convertors (DACs).  Exceptional power supplies were designed for every stage of the PCMII.
The four separate power supplies give substantial power reserves and stability, ensuring that the different signals are not compromised in any way and that the sensitive digital and analogue circuitry, the laser/servo system and the control sections do not interact.
 Highly consistent pre-selected DACs ensure superior linearity and purity of the output signals, resulting in true fidelity in the reproduction of the recorded program material.  To further enhance the PCMII’s superior sonic Performance, the system contains a variety of pioneering facilities.  These include remotely controlled; display “shutdown” to minimize digital traffic, absolute “phase-invert” for optimum extraction of the recorded information and an exceptionally transparent electronic volume control for ultimate ergonomics of the system.
For the more demanding audiophiles, the PCMII can also be upgraded by the addition of a Cyrus PSX external power supply unit.  Connection of the PSX to the PCMII feeds dedicated clean power to the analogue section, resulting in availability of more power reserves for other sections of the machine.  The enormous reservoir of pure power available to the analogue section of the PCMII makes for increased refinement of the system.
