Introduction
The Chapter Sonnet is a ‘State Of The Art’ audiophile two-channel CD Player, that incorporates years of Research and Development in digital to analogue converter, clock and power supply circuits. The Sonnet features a number of new design features along with scrupulous attention to technical detail. Our objective is to provide a product capable of great musicality and realism whilst boasting exemplary technical specifications. By bringing together engineers and designers with a lifetimes experience in audio and power system design we believe this objective has been more than achieved. The Chapter Sonnet is the essence of high fidelity, as you would expect of any Chapter product. Our goal, as always, is to produce a true reference quality CD Player. A product that can be held in the highest regard from both objective and subjective perspectives. After several years of research and development, we believe that we have succeeded in fulfilling the requirements of even the most discerning audiophile. 5

Unpacking your CD Player
The shipping weight of your Chapter Sonnet is 20 KG. Therefore, under normal circumstances, one person should be able to unpack the unit safely. If you are in any doubt, please obtain the assistance of a second person. To avoid back injury whilst carrying your CD Player (or any other piece of heavy equipment) please crouch with a straight back and use your leg muscles. After unpacking your CD Player, please retain all packaging for future transport. If you move house or you need to ship your CD Player, only the custom designed shipping carton is acceptable. Any other method of shipping may result in damage and such damage is not covered under warranty. Please inspect your CD Player for possible damage due to shipping. If you discover any, contact your Chapter dealer immediately.

Break In Period
Your Chapter Sonnet CD Player will deliver excellent performance straight out of the box, however, you should expect to hear it improve as it reaches its normal operating temperatures and its various components ‘break-in’. In our experience the most significant changes occur within the first 30 - 50 hours use, but the unit will continue to improve in sound quality for about 100 hours, after which time it remains quite consistent. If the power is removed and reconnected to the unit, you must allow a brief ‘warm up’ period for the unit to give off its best. However, it is not recommended to leave your Chapter Sonnet CD Player on permanently.

Installation
Your Chapter Sonnet has been designed to fit into a good quality equipment rack or amplifier stand. In most installations locating the CD Player near the amplifier is best. Where permitting, locate the power amplifier near the loudspeakers and use a longer pair of balanced interconnects to a quality pre amplifier such as a Chapter Preface unit. The advantage to this strategy lies in the fact that the interconnects carry low current signals that are easily transmitted over distances with greater accuracy than the high current signals required by loudspeakers. Your Sonnet CD Player has been designed to drive the most demanding of Interconnect cables. The back of your Sonnet CD Player has been laid out to keep every connection accessible. We recommend that you leave some clearance behind the unit to fit cables without having to bend them excessively. 7 In order to conform with CE regulations your CD Player is fitted with a rocker style power switch on the rear of the unit as well as a multifunction ‘standby’ touch sensor on the front of the unit. This rear mounted rocker switch disconnects power from the power supply, resulting in effective disconnection of the amplifier from the AC mains.

Ventilation
Please allow your CD Player to have at least five centimetres between the side covers and the side of an equipment rack. The slotted vents on the side of the unit must not be obstructed, as this would reduce the free flow of air through the unit.

Operating Voltage and Mains Conditions
A good quality three pin, 13 ampere IEC standard, detachable mains lead is provided for use with your CD Player. It is recommended that you use this lead. Please contact us for advice if replacement is required. The power supply is set at the factory to work at either 100 / 110 VAC or 220/240 VAC at 50/60Hz. Please use your amplifier in regions that have the same voltage conditions as those detailed on the back of your unit. If you move to a country that uses a different mains voltage please consult your distributor to arrange for your amplifier to be adjusted accordingly. Thus total audio performance is assured anywhere in the world.

Power Supply Topology
Our New ‘Balanced Zero Ripple’ power supply provides the amplifier sections with a rock steady power supply rails, essential for deep articulate bass, as well as a grain free treble performance. You will notice that even when pushed very hard by the music choice selected, the Sonnet will not change is sonic presentation. Great care is take to ensure that mains bourne noise (including DC components) do not enter the amplifier and thus compromise the amplifier performance - this filtering and in some cases blocking ensures that the Sonnet is essentially silent. Regulation and filtration are only part of the picture - a power supply must also be low noise, and not interfer with the other delicate parts of the circuit electrically or magnetically. It will take you only a few moments to hear that we have created a CD Player that can deliver a deftness of touch combined with tremendous punch. 8

Design Features
Finest Part Selection: The Sonnet uses the best sounding JFET devices available. All electrolytic capacitors, are a considered combination of Samwha and ultra low ESR Panasonic Gold series. All components used without our power supply and amplifier design have been auditioned for both performance, consistency and durability. At Chapter we also use the finest ‘Melf’ surface mount precision resistors. Balanced Zero Ripple Power Supply: This technology allows the benefits of a regulated supply without the size, heat and wasted energy of a conventional design Balanced ground layout: Cancels the ground currents that can cause Inter-modulation distortion and crosstalk in a conventional stereo design. Full Immersion Gold Printed Circuit Boards: Audio signals travel on gold track. As you would imaging, compared to copper and gold plate this is a very expensive to manufacture, but the sonic benefits are hugely tangible in terms of space, air and dynamics. Touch Sensor operation: In order to give the user full control over the amplifier, a series of touch sensors have been implemented into the unit that are subtle on the eye, and yet easy to use. These sensors can be used to change inputs, mute the amplifier, or change the lighting conditions on the unit. True Balanced Analogue Output Stage: The touching and elegant sound provided by the Chapter Sonnet is buffered by the pure Class-A fully balanced JFET output stage. A unique blend of Wima Black box capacitors and non magnetic inductors is used to filter data artefacts from the audio signal. Custom Manufactured VCXO Master Clock: This ultra low phase noise device is fully custom designed and built for Chapter. Utilising technology usually reserved for military and space aviation, an integrated jitter level of <0.2pS is achieved. More importantly the Chapter VCXO provides a unique phase noise characteristic for Audio purposes. Short term phase noise close to the carrier is dramatically reduced from commercially available clock parts. Clock Distribution Matrix: The Chapter Sonnet uses its own proprietary clock distribution system designed to maintain the VCXO phase noise characteristic through the whole digital system. Feedback is used to eliminate clock driver substrate noise within the system. 9
