Congratulations on purchasing this Cambridge Audio amplifier.
It has been designed using the results from an extensive
Research 8 Development program undertaken to identify the
circuitry and components fundamental to our highly regarded
and critically acclaimed products.

This knowledge has resulted In a reduced component count and
shorter signal paths which provide further enhanced
performance and improved reliability. The quality and value for
money offered by Cambridge Audio products now surpasses
even our high standards.

The performance of any amplifier is ultimately limited by the dynamic
abilities of it's power supply, and for this reason Cambridge amplifiers
feature generously over specified power transformers, discrete diode
rectification and selected high speed reservoir capacitors Power
regulation is also used wherever possible and our transformers are
custom designed. low flux type. allowing for the instantaneous clean
delivery of current whenever it is needed.

Particular attention has also been paid to the quality of the passive
components where close tolerance metal film resistors and audio grade
signal coupling capacitors are used throughout. Critical line level circuits
are also protected from electrical noise by our custom designed gold plated
shielding cans.

Some Cambridge Audio amplifiers also offer the provision oftone controls,
which in some cases. may be switched out of circuit in direct' mode for
the shortest and therefore purest signal path. Other features include
increased protection against accidental short circuits or sudden overload
and dual sets of high current loudspeaker terminals for easy bi-wiring.

This attention to detail results in amplifiers that are convincing in the
reproduction of both tonal colour and dynamic contrast, deliver a vibrant
and fluid performance with music of all types and are therefore musically
very involving, .

To gain the greatest musical rewards from this equipment we would
encourage you to use only high quality components and revealing
loudspeakers. We particularly recommend tuners and digital equipment
from the Cambridge Audio range. all of which have been designed to the
same exacting standards as our amplifiers.

Interconnects and speaker cables are also something that shouldnt be
overlooked, Please do not compromise your system's performance by
using poor quality cables to connect source components to your amplifier
or the amplifiers output to your loudspeakers. A system is only as good
as its weakest link. For this reason we do not include cheap freebie"
cables in the box, Your dealer can supply quality Cambridge Audio
interconnects and Gale loudspeaker cables that will ensure your whole
system realises its full potential.

Now we Invite you to sit back, relax and enjoy!
