CAMBRIDGE AUDIO Edge W Power Amplifier Instruction Manual

CAMBRIDGE AUDIO Edge W Power Amplifier

• 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.

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 at a maximum 45 degree C ambient temperature.
• The unit is of Class 1 construction and must 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.
