CD2 CD Player & SIA2-100 Integrated Amplifier, DAC
ATC’s reputation for the design and manufacture of unique high performance loudspeaker drive units is
legendary with new concepts of design evolving and being perfected continually since its inception in 1974.
The same is true of ATC’s equally innovative and successful high performance audio electronic products.
It all started in1982 with the EC23, a stereo, 3-way electronic crossover incorporating phase correction and
momentary gain reduction – features that are incorporated in all ATC active loudspeaker systems to this day.
The EC23 was the controller for all large ATC active loudspeakers right up to the development in 1996 of the
SPA24-850, a stand-alone stereo Ampack for the control and amplification of SCM200 and SCM300 monitors.
But it was the development of the SCM50A active 3-way monitor in 1985 that changed everything.
An aluminium plate and heatsink that bolted straight into the back of the loudspeaker cabinet onto which three
power amplifiers were mounted: 200W bass, 100W mid-range and 50W high frequency, incorporating phase
correction and momentary gain reduction. This technology is why all ATC active monitors have a flat magnitude
response, an excellent minimum phase response and are factory set to prevent the amplifiers from clipping
when driven hard. There is nothing else that sounds better or offers such great value.
In 1996, ATC designed and developed its first stand-alone hi-fi electronic product through the necessity
of the ongoing quest for the best possible performance money can buy. Few pre-amplifiers available at that
time could drive the long lengths of cable often necessary to link electronics to active loudspeakers.
ATC’s solution was to develop the SCA2 pre-amplifier with its unparalled audio performance, transparency and
current drive ability. Today, ATC has created a wide portfolio of high performance audio electronic products...
from the CA2 pre-amplifier to the exquisite P6 power amplifier.
In December 2011 the Company launched its first CD player, the CDA2, a design that also incorporated a pre-
amplifier and DAC. In response to changing listening trends, in early 2018 the CDA2 was significantly upgraded and
relaunched – the MkII model now boasting the latest high performance CD drive technology and USB interface
allowing playback of extremely high resolution PCM and DSD audio.
Seen as a further evolution of this highly acclaimed digital source is ATC’s new stand-alone CD player, the CD2,
which has been designed in parallel with a matching 100W integrated amplifier, the SIA2-100. Offering a built-in high
resolution asynchronous USB interface the amplifier also incorporates a premium AKM stereo 32-bit DAC.
Whilst designed from the outset to be partnered together, both the CD2 and SIA2-100 may also be purchased
individually to suit customers’ specific system requirements. Either way, these outstanding components offer
music lovers an exceptional combination of performance and functionality.
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, educators, studios and
musicians across the world that understand the value of the engineering that goes into every ATC product.
Built to give a lifetime of service and musical enjoyment all ATC products carry a six year guarantee.

FINDING THE PERFECT PARTNER
FOR YOUR CD2 AND SIA2-100
We are confident that both components will give many, many years of enjoyment and pleasure.
They have been created to deliver the very best performance money can buy.
The CD2 sounds sublime when partnered with our matching SIA2-100 integrated amplifier – unsurprisingly, of course,
as they were designed and developed side by side from the outset.
Whether hooked up to our CD2 or not, the SIA2-100 is one of those rare amplifiers that truly deserves its place in a system
built around some of the very best loudspeakers money can buy.
Speaking of which, our multiple-award-winning Entry Series range of passive monitors is a brilliant place to start:
SCM7, 11 and 19 two-way bookshelf/stand-mounted models and the SCM40 three-way floor standing ‘Tower’ are clear choices.
Prepared to extend your budget further? Then ATC’s world-renowned ‘Classic’ range of monitors such as the two-way passive
SCM20 offer hugely tempting, state-of-the-art alternatives.
Below: Entry Series bookshelf/stand-mount two-way passives – SCM7, 11 and 19.
Opposite: Entry Series SCM40 floor-standing three-way Passive, shown in the full range of finishes.
