Operating Voltage And Mains Conditions - Chapter Audio Preface Manual

Operating Voltage and Mains Conditions

A good quality three pin, 5 ampere IEC standard, detachable mains lead is
provided for use with your pre-amplifier. It is recommended that you use this lead.
Please contact us for advice if replacement is required.
The Chapter Preface uses several very low noise, double regulated, linear power
supplies to control digital, analogue and control circuitry. Using large custom made
screened transformers and a fastidious attention to circuit layout gives the unit
staggering noise performance, whilst an advanced mains monitoring system allows
the unit to ride through the most unsettled of mains conditions.
Unlike the award winning Chapter Two power amp, 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.
Total audio performance is thus assured anywhere in the world.
