SafetyWarnings

1. Read instructions – all the safety and operating instructions should be read

before the appliance is operated.

2. Retain these instructions – the safety and operating instructions should be

retained for future reference.

3. Heed warnings – all warnings on the appliance and in the operating

instructions should be adhered to.

4. Follow instructions – all operating and other instructions should be

followed.

7. Heat – the appliance should be situated away from heat sources such as

radiators, stoves or other appliances that produce heat.

9. Power cord protection – power supply cords should be routed so that they

are not likely to be walked on or pinched by items placed upon or against

them, paying particular attention to cords at plugs, convenience

receptacles and the point where they exit the appliance.

10. Cleaning – the appliance should be cleaned only as recommended by the

manufacturer.

11. Unattended periods – the power cord of the appliance should be

unplugged from the outlet when left unused for a long period of time.

12. Object entr y – care should be taken so that objects do not fall into the

appliance.

13. Damage requiring service – the appliance should be serviced by qualified

service personnel when:

i. the power supply cord or the plug has been damaged

ii. objects have fallen or liquid has been spilled into the appliance

iii. the appliance has been exposed to rain or other serious liquid exposure

iv. the appliance does not appear to operate normally or exhibits a marked

change in performance

v. the appliance has been dropped or the cabinet damaged

14. Servicing – the user should not attempt to service the appliance beyond

those measures described in the operating instructions.All other servicing

should be referred to qualified service personnel.

15. Grounding or polarisation – precautions should be taken so that grounding

or polarisation means for the appliance are not defeated.

5. Water and moisture - the appliance should not be exposed to dripping or

splashing and no objects such as vases, should be placed on the appliance.

6. Ventilation - a minimum 0f 80mm is required at the rear of the appliance

to ensure sufficient ventilation.The ventilation should not be impeded by

covering the appliance with items such as table-cloths,curtains etc. Further,

the appliance should not be built into an installation, such as a bookcase or

cabinet, that may impede the flow or air around the appliance.

8. Power sources -The appliance is of Class1 construction and shall be

connected to a MAINS socket outlet with a protective earthing connection.

16. The Mains disconnection switch is located on the rear panel.Pressing the

switch downwards will turn the unit on.The unit can be turned off by upward

pressure on the switch. Please allow enough room around the unit to ensure

the switch is readily operable when the unit is in use.

Welcome. In selecting ATC you have chosen an

example of the finest audio engineering

available. ATC was founded on a principle of

engineering excellence, and that principle still

defines our products today. Given the right

opportunities, ATC products will deliver

exceptional audio performance, but the

opportunities will only arise from careful and

thoughtful installation and use. Please read the

following manual fully. It will help you

understand the product and to realise its full

potential. We are happy to answer questions

and offer advice on any issues that arise

through installation or use of ATC products.

Contact details can be found at the back of this

manual.

ATC was founded in London in 1974 by Australian emigre Bill Woodman, who still

heads the company today. An enthusiastic pianist and engineer he was naturally

drawn to loudspeaker design and after a period working at Goodmans, where many

of the names that went on to found British loudspeaker companies began their

careers, he struck out on his own.The premise on whichATC began is a simple one,

and one that in many respects is still true today: hi-fi loudspeakers tend to be

detailed and accurate but of limited dynamic range, while professional monitor

speakers tend to express the opposite character. ATC products were designed from

the outset to offer the best of both. It’s an easy concept to describe,but surprisingly

difficult to engineer.

The difficulty inherent in designing such loudspeakers is one of scale. Hi-fi levels of

accuracy and detail call for lightweight moving parts and delicate engineering.

Professional monitor levels of performance however demand far more robust

components engineered to survive the rigours of high level use for extended

periods.The only way to combine the two is through precision engineering of a class

and scale more often associated with aerospace or motorsport. But the results are

worth the effort and the cost. ATC loudspeakers, with their unique in-house

designed drivers, combine the best of hi-fi and professional to devastating effect.

ATC has become synonymous with active systems. Choosing to offer active

loudspeakers (where the passive crossover network is replaced by active filters and

multiple power amplifiers) is simply a result of the uncompromising attitude to

loudspeaker design.While passive systems still have their place, and ATC engineering

skills can still bring remarkable results from them, “active” is a fundamentally better

solution to the problems posed by accurate, high level music reproduction.The ATC

instinct is always for the better solution. Not cheaper,not quicker, but better.

It was the development of active loudspeakers that first brought ATC into

electronics design and engineering. Active speakers demand multiple power

amplifiers so ATC from the mid 1980s became not just a loudspeaker manufacturing

company but an electronics manufacturer too.The further step from electronics for

active speakers to a range of stand-alone amplifier products was natural and now

means that ATC engineering is available from the recording desk or CD player

output to the ears.

From modest beginnings ATC has grown to become one of the very few

manufacturers successful across both domestic and professional audio. By selecting

ATC you join a group of music lovers, professional audio engineers, studios and

musicians across the World that understand and value the engineering that goes into

an ATC product - and the sound that comes out.
