First and foremost, thank you for choosing Cambridge Audio.
I’m sure that you’re excited to listen to your new acquisition;
I hope your expectations will be surpassed and that the pleasure will
continue for many years to come.
At Cambridge Audio we are in awe of the way that music can move
us. It’s something that isn’t easy to describe, but you know how
wonderful it is.
Personally, listening to a quality system provokes the same reaction
every time, it takes hold of me, possesses me and demands that I
listen. I can lose myself for hours on a voyage of discovery, playing
tracks that I haven’t heard in years, and they all sound brand new.
It thrills me, I’ll be nodding, grinning, tapping and if there’s a glass
of wine involved, dancing like a fool! It’s as exciting as hearing
the songs for the first time, but with the added delight of recalling
feelings and memories too. It really is a beautiful thing.
And that power is why we developed Edge, the pinnacle of five
decades of engineering precision, continuous audio innovation
and our lasting love of music. It’s the inevitable conclusion to the
singular objective that’s guided Cambridge Audio from the start; to
produce audio equipment that faithfully delivers a pure and natural
sound. Nothing added, nothing taken away.
Cambridge Audio was born in 1968, when a promising R&D business
established by some talented young technology graduates in
Cambridge, England, turned their attention to stereo amplifiers.
Britain in the 1960’s was an incredibly exciting place to be - a time
when British bands began to enjoy unprecedented global success,
our studios led the way in recording technology and a small group
of enterprising British engineers started to make equipment that
would accurately playback these landmark recordings.
50 years on, and all our engineering and design is still carried out
in the UK, by our dedicated teams in London and Cambridge.
There’s a few more of us working here now, and our head-office has
relocated to central London; where we proudly continue to
deliver world class hi-fi.
Our quest for audio perfection is built on simple principles;
minimise the number of components in the signal path and select
each component by listening to discover those with the purest
sound. We’re immensely proud of what we’ve created, having spared
nothing in our efforts for perfection.
But ultimately this is about far more than the equipment and it’s
even more important than the music, it’s about your experience
when you listen. We hope that your Edge will transport you to some
of the magical moments in your life, reminding you exactly why you
fell in love with music in the first place.
Time to sit down, take a breath, and let the music take you away,
wherever your heart desires.

apparatus.
11. Only use attachments/accessories
specified by the manufacturer.
12. Use with only the cart,
stand, tripod, bracket,
or table specified by the
manufacturer, or sold
with the apparatus.
When a cart is used,
use caution when moving the cart/
apparatus combination to avoid injury
from tip-over.
13. Unplug this apparatus during lightning
storms or when unused for long periods
of time.
14. Refer all servicing to qualified service
personnel. Servicing is required when
the apparatus has been damaged in any
way, such as the power-supply cord or
plug having been damaged, liquid has
been spilled or objects have fallen into
the apparatus, the apparatus has been
exposed to rain or moisture, does not
operate normally, or has been dropped.
WARNING:
- Do not place the unit in an enclosed
space; if you wish to place the unit
on a shelf, use the top shelf to allow
maximum ventilation. Do not put any
objects on top of this unit. Do not situate
it on a rug or other soft surface and
do not obstruct any air inlets or outlet
grilles. Do not cover the ventilation
grilles with items such as newspapers,
tablecloths, curtains, etc.
- To reduce the risk of fire or electric
shock, do not expose this apparatus to
rain or moisture . This unit must not be
used near water or exposed to dripping
or splashing water or other liquids. No
objects filled with liquid, such as vases,
shall be placed on the unit.
- Danger of explosion if battery is
incorrectly replaced. Replace only with
the same or equivalent type.
- The battery (battery pack or batteries
installed) shall not be exposed to
excessive heat such as sunshine, fire or
the like.
- The unit must be installed in a manner
that makes disconnection of the mains
plug from the mains socket outlet (or
appliance connector from the rear of the
unit) possible. Where the mains plug
is used as the disconnect device, the
disconnect device shall remain readily
operable.
- Please refer to the information on the
exterior rear panel for electrical and
safety information before installing or
operating the apparatus.
- Only use the mains cord supplied with
this unit.
Use of the apparatus in tropical
climates - The equipment shall be used

be connected to a mains socket outlet with
a protective earthing connection.
The lightning flash with the arrowhead
symbol within an equilateral triangle is
intended to alert the user to the presence
of un-insulated ‘dangerous voltage’ within
the product’s enclosure that may be of
sufficient magnitude to constitute a risk of
electric shock to persons.
Warning: To reduce the risk of electric
shock, do not remove cover (or back) as
there are no user-serviceable parts inside.
Refer servicing to qualified personnel.
The exclamation point within an
equilateral triangle is intended to alert the
user to the presence of important operating
and maintenance instructions in the
service literature relevant to this appliance.
VENTILATION
Important!
The unit will become hot when
in use. Do not stack multiple units on top
of each other.
Ensure that small objects do not fall
through any ventilation grille. If this
happens, switch off immediately,
disconnect from the mains supply and
contact your dealer for advice.
POSITIONING
Choose the installation location carefully.
Avoid placing it in direct sunlight or
close to a source of heat. No naked flame
sources, such as lighted candles, should
be placed on the unit. Also avoid locations
subject to vibration and excessive dust,
cold or moisture. The unit can be used in a
moderate climate.
This unit must be installed on a sturdy, level
surface. Do not place in a sealed area such
as a bookcase or in a cabinet. Do not place
the unit on an unstable surface or shelf. The
unit may fall, causing serious injury to a
child or adult as well as serious damage to
the product. Do not place other equipment
on top of the unit.
Due to stray magnetic fields, turntables or
CRT TVs should not be located nearby due
to possible interference.
Electronic audio components have a
running in period of around a week (if used
several hours per day). This will allow the
new components to settle down and the
sonic properties will improve over this
time.
POWER SOURCES
The unit should be operated only from
the type of power source indicated on
the marking label. If you are not sure of
the type of power-supply to your home,
consult your product dealer or local power
company.
If you do not intend to use this unit for a
long period of time, unplug it from the
mains socket.
OVERLOADING
Do not overload wall outlets or extension
cords as this can result in a risk of fire or
electric shock. Overloaded AC outlets,
extension cords, frayed power cords,
damaged or cracked wire insulation and
broken plugs are dangerous. They may
result in a shock or fire hazard.
Be sure to insert each power cord securely.
To prevent hum and noise, do not bundle
the interconnect leads with the power cord
or speaker leads.
CLEANING
To clean the unit, wipe its case with a dry,
lint-free cloth. Do not use any cleaning
fluids containing alcohol, ammonia or
abrasives. Do not spray an aerosol at or near
the unit.
BATTERY DISPOSAL
Batteries may contain substances harmful
to the environment. Please dispose
of any discharged batteries with due
consideration and in accordance with
local environmental/electronic recycling
guidelines.
SERVICING
These units are not user serviceable.
Never attempt to repair, disassemble or
reconstruct the unit if there seems to be
a problem. A serious electric shock could
result if this precautionary measure is
ignored. In the event of a problem or
failure, please contact your dealer.
