ATC SCM 150A SL Pro: full-size very high performance active 3-way studio monitor
The ATC SCM 150A SL Pro is a further development of the SCM 100A SL Pro, substituting a larger 375mm Super Linear bass driver driver, and increasing the enclosure size to 150 litres. The result is extended bass, greater headroom, and even more dynamic range.
The SCM 150A SL Pro features a built in three way amplifier with frequency, gain and phase correction which has been individually optimised at the ATC manufacturing facility. Adjustment of input sensitivity and bass boost are available to the user via controls on the rear panel of the unit.
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 theWorld that understand and value the engineering that goes into an ATC product - and the sound that comes out. |
