ATC CA-2 MKII Pre-Amplifier
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.
Connections
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.
