ATC SCA2 Pre-Amplifier
Product Description
ATC SCA2 preamplifier is as a no-compromise preamp to partner ATC's range of active loudspeaker systems and is designed to enhance the performance of any audiophile separates system.
ATC SCA2 Performance
The ATC Preamp achieves an open, neutral and transparent performance with a solid soundstage, which is both wide and deep. Voices are reproduced with realism, warmth and articulation; the Bass takes on a rich, superbly controlled solidity and the Percussion is handled with great speed and definition.
As you'd expect from a design as highly spec'd as ATC SCA2, the dynamic range is outstanding. With 8 inputs capable of accepting both balanced and unbalanced signals, the ATC SCA2 preamplifier also has balanced and unbalanced outputs to connect to the rest of your system.
Discrete Gain
A key feature of ATC’s SCA2 preamp is the total elimination of audio integrated circuits in the main signal path, which is made possible thanks to ten high-performance discrete circuitry gain blocks. Furthermore, all amps in the monitor chain are of similar type and built from discrete bipolar transistors and FETs.
Low Distortion
ATC’s SCA2 is a high output, low distortion amplifier with a very wide bandwidth that is easy to use in conventional feedback configuration because it has only one stage of gain, meaning there is only one possible source of roll-off and phase shift at high frequency. The result is remarkable audiophile product, which, in both laboratory and subjective listening tests, clearly redefines state of the art.
Construction
ATC’s preamp uses the finest components and high attention to detail to make sure this performs at the very best. The power supplies are super quiet and all circuitry is contained on a single PCB to eliminate wiring for better wound quality. Aerospace quality metal work creates an enclosure of great beauty and durability.
