      Description

      Rega’s flagship CD player, the Isis, is a product manufactured to the highest achievable quality inside and out including Rega's own unique CD technology, genuine black chrome lid and front facia and a custom solid anodised aluminium case weighing in at a notable 19kg! We hope you enjoy this very special CD player; we have spent a very long time creating it, drawing on our many years of experience in specialist hi-fi manufacturing.

      Technology behind the design of the Isis

      One important design goal 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). The class A current to voltage conversion amplifier, evolved out of the development of the first stage of the Rega Ios MC amplifier.

      It shares identical demands of low noise, high drive capability and gain bandwidth required of the voltage to current amplifier. 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 was included in the final design.

      Analogue section

      The analogue section employs two Burr Brown PCM1794 digital to analogue converters, running in a parallel dual mono mode, driving a high-performance discrete class A current to voltage amplifier.

      The analogue stage has its own dedicated 50VA mains transformer which ensures galvanic isolation between the digital and analogue sections of the player. You will find 10 separate power supply regulators are used in the analogue circuit and each individual amplifier stage has its own dedicated low noise voltage reference.

      Digital section

      The digital section is blueprinted 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.

      Digital

      This revolutionary 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.

      USB Input

      Allowing direct connection to a laptop or PC via a USB A-B lead to stream internet radio, MP3 or WMA files directly from your computer via the high-quality Isis internal DAC.

      The USB input uses an isolated double-clocked USB interface, which permits the digital to analogue stage to be used with a computer USB interface and its own regulated power supply.

      Disc Analysis

      The Isis 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 Isis will adjust itself to each disc in order to give optimal trouble-free reading.
