AC power cord. To prevent the possibility of shock all three connections must be used. To clean your Chapter product please use a soft damp cloth. Never use flammable or combustible chemicals. Never operate this product with any covers removed. -
Page 4: Thank You From Chapter
From all of us at Chapter... Preface Mk 2 From dream to reality... Thank you for choosing the Chapter Preface Pre-Amplifier. It has been designed and manufactured to the highest possible standards in order to give you many years of musical enjoyment. -
Page 5: Introduction
The Chapter Preface is able to handle all of today’s high-resolution sources, with the fidelity that you would expect of any Chapter product. -
Page 6: Unpacking Your Pre-Amplifier
If the power is removed and reconnected to the pre-amplifier, 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 Preface Pre-Amplifier on permanently. -
Page 7: Installation
Installation Your Chapter Preface Pre-amplifier has been designed to fit into a good quality equipment rack or amplifier stand. In most installations locating the pre amp near the source components is best. By doing this you minimise the length of any unbalanced interconnect cable that you may be using. -
Page 8: Operating Voltage And Mains Conditions
The input voltage from which the Preface will operate is factory set to either 110V or 230V. As the transformers in the Chapter Preface are custom made to our specification, there is no difference in unit performance if operated at 230V 50Hz or 110V 60Hz. -

Brown. All electrolytic capacitors, are all ultra low ESR Samwha or Panasonic Gold series. On the power supply we use the finest sounding regulators our own custom screened mains transformers. At Chapter we also use the finest full immersion gold Printed Circuit Boards and ‘Melf’ surface mount precision resistors. - Page 10 Getting Started... When applying power to your Chapter Preface Pre-Amplifier for the first time please ensure to operate the rear panel AC mains switch. This allows the amp to enter standby mode. Whilst in Standby mode the sensitive voltage gain stages are still powered up to ensure that the unit will sound at its best after only a short period of time.
- Page 11 -60 and -50dB and 0.1dB steps from -50dB to +6dB (input gain set to x2) or +12dB (input gain set to x4). The fully custom Chapter volume control circuit uses two distinct ranges, ultra high precision (-86dB to -50dB) for low level listening and Standard precision (-49.9dB to +12dB) for general listening.
- Page 12 1, RCA input 2, RCA input 3, RCA input 4. Default is set to XLR input1. To preserve Bass quality, the Chapter Preface does not use a DC servo. Therefore, to avoid any clicking on changing inputs, the volume will automatically ramp down upon changing input, and will only ramp back up once a new input has been selected.
- Page 13 Front Panel continued Sleep Mode Press the right knob once more to open up the Sleep mode menu. This feature allows you to shut down the display and micro controller down after a time period selected by you. To activate sleep mode rotate the knob from the ‘OFF’ position, after which point you will be able to select the amount of time that the display remains active before going into sleep mode.

Single-ended Inputs x 5: Labelled: RCA INPUT 1, RCA INPUT 2, RCA INPUT 3, RCA INPUT 4 & RCA INPUT 5. Your Chapter Preface accepts analogue signals via RCA single ended interconnect cables on the aforementioned inputs. Balanced & Unbalanced Preamp Outputs Your Preface unit can drive an additional power amplifier for bi- amping purposes. -
Page 15: Remote Control
WRONG PICTURE Remote Control Volume Up Pressing this button on the handset, increases the volume on the pre amplifier. Volume down Pressing this button decreases the volume on the pre amplifier. Power On / Off This activates the unit from standby or returns the unit to standby mode. Mute - On / Off This mutes the outputs. -
