Product Description

ATC CA2 MKII is a two channel stereo design aimed where high-quality, low-cost compact listening solutions are necessary. The performance goes far beyond what you would expect for the price range.

When you first hear it, the transparency, wide bandwidth and low distortion are sure to amaze even the most discerning audiophiles.

Cutting Edge

Developed to drive both passive and active loudspeakers, CA2's most likely partners will be ATC’s Active T16 and Active 10 systems. SACD and DVDA ready, the ATC CA2 has a wealth of cutting-edge electronic design aspects.

It features a slimline case with the front panel and controls machined from solid aircraft-grade alloy. Easy turn controls and soft action buttons continue ATC’s tradition of total hand-built quality and durability.

Power Supply

Discrete components are used in the signal path rather than integrated circuits and a great deal of care has been taken over the power supply arrangement. The power amplifier is a dual mono design, with a dedicated mains transformer for each channel.

The design is entirely consistent with the preamp in attempting to minimise noise while delivering a wide band signal. Capable of driving cables up to 50 metres in length it makes an ideal choice for active systems. 

Input Stage

Circuitry has been designed specifically to avoid phase distorting ICs in the signal path, making full use of discrete component gain blocks. The input stage features a dual long tail pair of complementary transistors with cascaded junction FETs providing constant collector voltage. Output of the current mirrors is buffered by a pair of complementary Darlingtons.


There are separate power supplies for each channel, plus a digital input control. The ATC CA2 can be operated either from the front control panel or via its all-function, remote. It offers five line level unbalanced RCA style inputs including an onboard RIAA phono stage, while a separate tape loop is included with the monitor option selected by a single push button.

Press Reviews

  • 'ATC may be best known as a speaker company, but this preamp proves it builds great amps too… Transparent, honest and revealing presentation, sturdy build, simple to use.' (What Hi-Fi Magazine November 2009)

  • 'At this price tonal neutrality should be a given, and it is here: this pairing (CA2/P1) sounds impressively faithful to whatever instrument or voice it's asked to reproduce.' (What Hi-Fi Magazine November 2009)

  • 'The ATC sounds firmly in control, no matter how complex or demanding the material is. Listen to the kind of music that makes most amps crumble and this will take it in its stride, delivering all the drama required without sounding like it's working hard. The same remains true at high volume levels, too.' (What Hi-Fi Magazine November 2009)

  • 'We'd like to go on about the pleasing stereo imaging – it's focused and stable, even when the music gets busy – and the power amplifier's way of taking charge of speakers in a manner well beyond what we'd expect from something rated at 150 Watts per channel.' (What Hi-Fi Magazine November 2009)

  • 'Build quality is good. Everything feels solid and well put together: as with the audio performance there's nothing particularly flashy on offer here, just good, solid engineering.' (What Hi-Fi Magazine November 2009)
