Details:
| The Rega Isis CD player is manufactured to the highest achievable quality inside and out, Rega's own unique CD technology, genuine black chrome lid and front facia, a custom solid anodised aluminium case weighing in at a notable 19kg ! We hope you enjoy this very special CD player; Rega have spent a very long time creating it, drawing on their many years of experience in specialist Hi-Fi manufacturing |
| One important design goal with the Rega Isis CD player was to take the current output, with no internal amplification within the D to A converter, and convert this to an analogue voltage, using discrete class A operational amplifiers and filters. This circuit can then be optimised for sonic performance. (With most CD players the use of standard operational integrated circuits locks you into the sound of those particular integrated circuits, thus narrowing the scope for improvement). |
| With the Rega Isis CD player careful choice has been made for every component in the digital and the analogue signal path to ensure the integrity of the signal. The analogue and digital sections are bonded together using a substantial ground plane. It was found during the development of the player that adoption of RF ground plane techniques aided the sonic quality and therefore were included in the final design. |
| Careful design of the PCB's ensures isolation of not just the digital and analogue sections, but also the motor, display and user interface processor |
| The Rega Isis CD player uses enhanced and optimised control code for the control of the CD processor and user display. This speeds up the initialisation process by means of a tighter control interface between the user micro and CD processor. |
| The digital section is blue printed and selected, with major improvements to the mechanism, optical amplifier, DSP core, PLL, master clock & motor power supplies. Another 10 separate power supply regulators are used in the digital circuit. The motor, user interface processor & display also have their own power supply. The digital stage also has its own 50VA transformer again ensuring galvanic isolation. The mechanism is graded and matched to the servo circuits, to ensure the servo and optical amplifiers are working at their optimum point, improving error correction and playability. The headroom of the optical amplifier has been improved by 10% by increasing the voltage in the power supply |
| The revolutionary Rega Isis CD player has been five years in design. Rega, together with its design partners have pioneered a highly advanced servo controller that uses the latest signal processing techniques to ensure that the raw data that is recovered from the disc is of the very highest quality. Because our fully digital servo can use highly advanced algorithms the laser spot is kept in the optimum position for data recovery in terms of focus, size and tracking |
| The Rega Isis CD player will analyse each disc on an individual basis. During the initialising period (rather like the engine management system on a modern car which optimises the engine settings to temperature, fuel quality etc.) the Rega Isis CD player will adjust itself to each disc in order to give optimal trouble free reading. For this reason the Rega Isis CD player will often play discs with marks or scratches that other players cannot read. |
