Lets review external sound card AudioTrak DR. DAC3, which supports sound processing mode with 192 kHz sampling rate and 24 bits precision. It communicates with computer via USB port, through which it also receives power. Its digital to analogue converter ( DAC ) has 129 dB signal to noise ratio ( which is very good and provides very good sound quality, if all other sound card’s equipment supports audio processing with such high signal clearness ); it has unbalanced RCA outputs and monitor headphones outputs with separate volume level control and RCA inputs. Card supports digital optical S/PDIF input and output via TOS-LINK and RCA connectors. Sound card sizes are : 140 x 111 x 30 mm ( width x depth x height ), weight is : 400 g, and it consumes 3 – 5 W of energy, depending on workload level. There are drivers released for audio interface for Window XP, Vista, 7, 8 and newer and Mac OS X operating systems with support of ASIO 2.0 and Core Audio, accordingly; through which it can work with all modern DAWs : FL Studio, REAPER, Cackewalk Sonar and others.

As it can be seen from AudioTrak DR. DAC3 printed circuit board ( PCB ), it has operational amplifiers ( OA ), which can be easily replaced with better ones, and film or ceramic capacitors of low-pass filters, which filter out high frequency noise after OA. Use of such capacitors is much more preferable in analogue part of sound cards, because they have much better and much more stable characteristics, than electrolytic capacitors, which can boil-up and explode after some time of use. Key outputs of card has gold-plated surface : it provides good contact, when gold-plated connectors are used ( there is need to remember, that nickel-plated connectors can not be used in such case, because otherwise areas of contact after some time of use will be covered with oxide film, that lowers contact quality ). Overall AudioTrak DR. DAC3 is very good sound card, which can be recommended for home or semi-professional small studio.
