CDA2 & SIACD I n t ro duct i on Welcome. In selecting ATC you have chosen an example of the finest audio engineering available. ATC was founded on a principle of engineering excellence, and that principle still defines our products today. Given the right opportunities, ATC products will ATC has become synonymous with active systems.
CDA2 & SIACD Ge n e ri c I nf o r m ation The information in the following Sections is common to all ATC Remote Handsets electronics products. We recommend that you read this page, and the The CDA2 and SIACD are supplied with an safety warnings that proceed it, before continuing to read the pages SCA R2 remote handset. Provided that the CDA2 dedicated to your specific ATC product.
CDA2 & SIACD C a re a n d M a i n t e n a n c e ATC use high technology material finishes in all products. The surfaces are durable and with a little care can be kept as good as new even under conditions of heavy use. Normally a dry duster is all that is required to keep the finishes clean. Heavy soiling can be cleaned using a slightly moistened cloth with a non-abrasive household cleaner.
C D Pl a ye r & Pre a m pl i fi e r C DA 2 D e s c ri p t i o n CDA2 Inputs The CDA2 will accept unbalanced RCA phono style input plugs on Analogue inputs 1 and 2. The CDA2 Stereo CD preamplifier has been designed to partner ATC active, and Analogue input 2 will also accept a 3.5mm stereo with an appropriate Power Amplifier, passive loudspeaker systems. It incorporates 2 jack plug. The signal on unbalanced phono inputs is line-level analogue stereo inputs on RCA phono sockets, together with a 3.
