ATC CDA2 CD/DAC/Pre amp

PLEASE CALL OR MAIL US TO ARRANGE A DEMONSTRATION.
£2 153.00

The new CDA2 CD/Pre-amp/DAC is hand built by ATC Loudspeaker Technology in the UK. As ATC’s first source component the unit comes with added digital to analogue conversion and pre-amp facilities. The CDA2 is housed in a rugged yet elegant chassis, complimenting the rest of ATC’s range of outboard pre and power amplifiers.

The pre-amplifier design is taken from the company’s very successful CA2 pre-amp and uses discrete components throughout to give very low distortion and noise and an extremely wide and flat frequency response. There are two line level analogue inputs and two digital inputs. One analogue input is equipped for RCA/phono connections and the second RCA/phono and 3.5mm jack. Both digital inputs are equipped for coaxial and Toslink connectivity giving a total of 4 digital inputs. Fully differential (balanced XLR) and single-ended (unbalanced RCA/phono) outputs are provided for simple connectivity with a wide range of power amplifiers and active loudspeakers. The discrete output stage is capable of driving 9V r.m.s. (unbalanced) and 18V r.m.s. (balanced) into 100 ohms with no signal degradation allowing the use of long output cabling where required.

The discrete headphone output is specified to drive a very wide range of headphone sensitivities and impedances. It features very low distortion noise and extremely wide and flat frequency response for best possible performance.

The DAC utilises a Wolfson chipset and is compatible with 16 to 24 bit word lengths and sample rates up to 196kHz. Excellent digital clock recovery ensures signal integrity is maintained even with poorer quality digital sources and long cable runs between external sources and the CDA2.

The chassis is constructed from a combination of steel and aluminium and uses constrained layer damping to control panel resonances. The front panel is machined from an extruded section of 13mm/0.5” aluminium alloy with a brushed and anodised silver finish.
