With the ability to drive both active and passive loudspeakers, the ATC CA2 Stereo Preamplifier packs a wide range of intuitive, cutting-edge technologies, including being SACD and DVDA ready. With a slimline case with front panels and controls created using solid aircraft grade alloy, the design is robust yet simple to use. This simplicity in control can be achieved thanks to the easy to turn, soft action buttons that ATC have used to continue in their tradition of hand built quality and absolute durability.

As for the ATC CA2 Pre Amplifier MK2’s power supply, this preamp uses discrete components in the signal path rather than using integrated circuits. ATC has taken great care when creating the power source arrangement. The power amplifier uses a dual mono design, dedicating a mains transformer for each individual channel. This design works with the preamp to minimise noise while delivering a wide band signal. The CA2 is also capable of driving cables up to 50 metres in length, making it the perfect choice for use with active systems.

The circuitry has been specifically designed in such a way as to fully utilise the discrete component gain blocks to avoid any phase distorting ICs in the signal path. The input stage contains a dual long tail pair of complementary transistors with cascaded junction FETs that work to provide a constant collector voltage. Output of the current mirrors is buffered by a pair of complimentary Darlingtons.

There are separate power supplies for each channel, plus a digital input control. There are also many connection options available to you with the ATC CA2, including five line level unbalanced RCA style inputs with an on-board RIAA phono stage, and a separate tape loop included with the monitor option with the monitor option selected via a single push button.

About ATC

ATC was formed in 1974 by Billy Woodman to manufacture custom drive units for the professional sound industry, they quickly made their mark with the 12″ PA75-314 driver, a design capable of handling more power and producing less distortion at a higher sound pressure level than any other unit on the market.

1976 saw the first production of the ground-breaking SM 75-150s soft dome midrange driver, a technical tour-de-force, whose innovative up-scaled design reproduced a more uniform dispersion, wider bandwidth and much lower distortion than was thought possible at the time. It revolutionised studio monitoring and has since become recognised as the ultimate mid-range transducer for both domestic and professional applications. Utilising exotic materials and precision tolerances, the latest version of the SM 75-150s represents the apex of drive unit technology. It is often copied but never equalled.
