Due to the nature of the electronics in ATC amplifiers it is quite normal for a sound

to be heard from the speaker when the power is applied or disconnected.The noise

heard will not damage the speaker and is quite normal. Although ATC uses the

highest-grade components, a different noise may be heard from each speaker due to

slight tolarance variations in the amplifier components.

The ear and brain tend to interpret distorted sound as loudness and thus

underestimate the actual level of undistorted sound. The SCM200 and 300, like all

ATC monitors, demonstrates very much lower levels of distortion than conventional

systems of a similar size and it is therefore advisable to begin listening at an

artificially low level and carefully increase the volume. It is also possible for the

SCM200 or 300  to produce sufficient sound pressure levels for your ears

themselves to become a source of distortion and make the sound appear harsh.Any

audible distortion indicates that either the system or your ears are being overloaded

and that the volume level should be reduced.

High technology material finishes are used in this product.The surfaces are durable

and with a little care can be kept as good as new even under conditions of heavy

use. Normally a dry duster will be all that is required to keep the finishes clean.

Heavy soiling can be cleaned using a cloth slightly moistened with a non-abrasive

household cleaner.

There are no components within the speaker that can be considered expendable, or

that would benefit from regular maintenance. There is no requirement for any kind

of routine service work and there is no schedule for preventative maintenance.

There are no user replaceable parts within the speaker and in the unfortunate event

of any malfunction, repair should be referred to either the supplying dealer or

consultant, the relevant importer, or ATC. ATC has every confidence in the quality

of each product that it manufactures.
