In this article we will describe external professional sound card AUDIOTRAK PRODIGY CUBE BLACK EDITION. It has high quality digital to analogue converter Wolfson, which works on 94 kHz frequency with 24 bits precision, and National Semiconductor LME49860 operational amplifiers ( OpAmps ), which provide high quality sound without addition of noticeable amount of noise. There is ability to replace them on OpAmps of even higher quality, because they are mounted via special socket. Card has built-in electrolytic capacitors Sam Young AHS Series in digital and in most of analogue parts of it; from one side : they have good enough quality, but from the other side : it is better to place into analogue tract ( and into digital also ) high quality ceramic or film capacitors, because they have much better quality and characteristics, than electrolytic capacitors, for audio tract. And only in Low-Pass filters after OpAmps it has film capacitors WIMA Film Capacitor.
