Introduction

Your Rega Jupiter has been designed to be effective, easy to use
and with the performance to rival even the most expensive and
esoteric CD players, but at a sensible price. We have omitted all the
useless gimmicks and genuinely concentrated the manufacturing
costs on high quality component parts, and employed a unique
design direction, both necessary to reproduce a musical sound
quality from a digital source of information.

For example: A complex sub-chassis suspension is normally
necessary to isolate the CD player. However, they are detrimental to
the sound quality and degrade in time, causing malfunction. Rega
have designed a VCS* foot system which minimises footfall shock,
and therefore eradicates the need for a suspension, while maximising
sound quality by reducing error correction.

Rega’s design skill and the use of extremely high quality components
ensure that your Jupiter will perform at its optimum.
The tips that follow may help to give you maximum musical
enjoyment and ease of use for many years.

*VCS - Viscous Coupled System

Mission Statement

Rega’s philosophy is to make high quality products at sensible prices, as a means

of reproducing music as faithfully as possible. Rega is committed to the design

and development of new and existing products, both in hi-fi and other areas, that

will perpetuate Rega’s values of quality and value for money.

Design Innovation

The Jupiter is the old Jupiter And Io in a single case. It is housed in
the new Rega custom built extruded aluminium case and includes the
heat sink base assembly to give added stability to the mechanical
parts. It uses the same basic circuit topology as the existing Jupiter
And Io but with improvements in the DAC, power supply & clocking
stages. The Jupiter has additional sonic improvements, to give a
higher level of performance over that of the planet. The Jupiter also
has the new lid assembly.

Digital to analog converter

The dual differential Digital to Analog converter is based around two
custom built IC40 DAC chips with separate DAC's for the left and
right channels. DC servo control has been used in the post DAC
amplifier and filter stages thereby keeping the capacitors in the signal
path to a minimum.

Power supply

The power supply is made up from 7 separate power supply's feeding
the mechanism, PLL, DAC digital & analog sections, micro controller,
display, analogue amplifier and filter.

All the stages for the clock PLL and in the signal path are double
regulated. There are two physically separate raw supplies for the
noisy stages (motor drivers etc) and for the clean stages (DAC, clock
& DSP etc). The Jupiter has a generously rated toroidal transformer
with separate windings for the two raw power supplies.

Data Regeneration process

The signal from the mechanism is processed by a data regeneration
stage, where the data, Bit Clock & Word Clock are re-aligned and
then fed to the Rega IC40 DAC's for conversion.

Clock

The Jupiter uses a high stability oscillator module for the main clock.
The Master clock feeding the CD mechanism and DSP is derived
from a PLL clock stage for added stability.

Mechanism

The Jupiter uses a high performance CDM145BL-5BD25 kit with an
improved display and a better level of user functionality.

Rega has developed an ‘intelligent’ auto locating puck system and
has incorporated this high performance HMSS (High Mass Stainless
Steel) puck into the top loading design of the Jupiter.

Output Connections

All the outputs are made via RCA (Phono) type connectors. The
sockets on REGA products are clearly marked red, white and black.

Line Out: For output to an audio amplifier.
Right: always the lower row and marked in RED.
Left: always the upper row and marked in WHITE.

Digital Out: for output to digital components such as D.A converter,

digital processor, DAT, or MD, and marked in BLACK.

(Always check that the connecting component is compatible with

44.1k coaxial S/PDIF input.)

IMPORTANT: Always turn off the player when changing leads.

Installation

Ensure the operating voltage of the Jupiter (stated on the rear) is the
same as that of your local power supply.

The Jupiter will work well on most surfaces, such as a shelf, table,
stand, or wall bracket.

The Jupiter should be placed to allow adequate access to the lid and
aperture. If access is limited there is a danger of scratching the CD
when sliding it over the hub.

NOTE: The foot suspension has been designed to absorb the
shock of normal footfalls, but can be made to skip if exposed to
more extreme impacts. If this could be a problem then the player
should be further isolated by a wall bracket or other method.

Interconnects

The Couple interconnect is available for your Jupiter CD Player. It
uses high specification cable with Neutrik phono (RCA) connectors.
