SCM50/100/150 Introduction 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 ATC was founded in London in 1974 by Australian emigre Bill Woodman, who still thoughtful installation and use.
SCM50/100/150ASL Installation 1. Unpacking and Handling The SCM50, 100 and 150 are large, heavy items and should be handled with care. Always employ a second person to assist in moving it. Unpacking them requires a large, open space, preferably near their final position. • First lay the carton down and open the flaps on its side.While holding the flaps apart turn the carton over so the open side is Diagram 1 - input connection pins on the floor. • Lift the outer carton off the inner packing.

Adds more warmth and energy to the lower frequencies in music, at the expense of accurate transient Balanced cable configuration is the preferred reproduction. Note: Adjusting the bass boost without the ability to recalibrate option, however unbalanced connection is possible. may leave a pair of monitors unmatched.

SCM50/100/150SL 5. Listening The ear and brain tend to interpret distorted sound as loudness and thus underestimate the actual level of undistorted sound. The SCM50, 100 and 150, like all ATC monitors, demonstrate 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.
