AUDIOTRAK DR.DAC2 DX Digital To Analog Con...

The highest DAC and high-power dual headphone amplifier are incorporated technically, as well as DR.DAC2 DX support USB audio feature to build HiFi audio system of computer-based, and It is provide the most advanced digital audio solutions. We have adopted Ti's DAC, PCM1798, which has the best performance of the Dynamic Range: 123dB and THD+N: 0.0005%, provides 24bits/96kHz specs. and perfectly materialized a Triple OPAMP circuit utilizing the FDO (Full Differential Output) technique which is actually applied to the best HiFi Audio Systems. We have adopted SANYO's OS-CON(high-end quality SP series), WIMA's condenser high quality Film Capacitor which adopted LPF(Low-Pass Filter), and we have adopted high-quality electrolytic condenser SamYoung's Low ESR Electrolytic Capacitor(LXV series) for stable power supply. So, DR.DAC2 DX is more perfectly designed to provide high-quality ear for music.   DAC DR.DAC2 DX connects source device which supports the digital output of CDP, or DAT, etc. and digital output of computer sound card, it provides High-quality analog of the HiFi-audio level through Ti's High-performance DAC PCM1798 and Triple OPAMP circuit of the FDO (Full Differential Output) method etc. so it supports S/PDIFz, 176.4 kHz, and 192.0 kHz) of Optical/Coaxial standard and USB Input (44.1 kHz, 48.0 kHz, and 96.0 kHz), and you selectively can use RCA Line-out and dual headphone-out. Headphone Amplifier The dual headphone amplifier boasts of driving power and high-resolution, it is also show the performance from High-level headphone of 600 ohms. Especially, if you connect your CD player to DR.DAC2 DX, you can feel the enormously high quality sound you've never experienced because its output rises theoretically to the uppermost limit of the sound quality which a CD player could possibly have. USB Sound Card DR.DAC2 DX contains a high-performance USB controller chipset that supports 24bits/96kHz specs, so it can be used as a USB external sound card by connecting your devices to the ports of your desktop or laptop computer. When you use it as a USB mode, you can also use the high-performance DAC and the high-performance headphone amplifier, the digital output of 5.1-channel is available to support Dolby Digital(AC3) / DTS PassThrough, and It can be lossless recording about internal radiophonics and S/PDIF Input(Optical, PCM signal). WIMA is located in Germany and WIMA has a long tradition in the field of passive electronic components. It was founded by Wilhelm Westermann in Unna/Westphalia in 1948. Within only a few years he extended his company into one of the leading specialists in capacitor production. WIMA is a privately owned company and the president today is Dipl.-Ing. Dipl. Wi.-Ing. Wolfgang Westermann. WIMA??s strength lies in the design and production of customized products requiring experience and highly developed expertise. We have adopted the best film condenser for coupling, WIMA condenser. and, they made every endeavor to improve sound quality.SAMYOUNG ELECTRONIS was founded in 1968. The electrolytic condenser developed based on our own technology, this obtains with most market. We have adopted high-quality electrolytic condenser SamYoung's Low ESR Electrolytic Capacitor(LXV series) for stable power supply. So, DR.DAC2 DX is more perfectly designed to provide high-quality ear for music.OS-CON is an aluminum solid capacitor with high conductive polymer or organic semiconductor electrolyte material. OS-CON acquires low Equivalent Series Resistance (ESR), excellent noise reduction capability and frequency characteristics. In addition, OS-CON has a long life span and its ESR has little change even at low temperatures since the electrolyte is solid.Low ESR obtained by using conductive polymer electrolyte.Suitable as a decoupling capacitor, because its impedance has ideal frequency characteristics. Suitable as a smoothing capacitor, enabling miniaturizing switching power supplies, because it allows large ripple current. Suitable as a backup capacitor for the circuits that consume large current at a high speed.   Power supply DC 15V / 1A~2A Dimensions / weight 140(mm) x 111(mm) x 30(mm) / 440g Headphone Output Type Maximum Out Level Maximum Load Power THD+N Impedance 1/4” Stereo phone jack Port 1 : +8dBV (6Vpp) / Port 2 : +20dBV (24Vpp) 300mW 0.0008% A-weighted (@ 100mW, 1kHz) 0O (Load : 16 ~ 600) Line Input / Output Type Level Impedance Unbalanced RCA -10dBV Nominal (@-16dBFS) / +8dBV max 15kO(Input) / 200O(Output) USB Audio Type Max 24bit / 96kHz, USB 1.1 / 2.0 Compatible OS Support Support Windows 7, Windows Vista, Windows XP, Mac OS-XNote: The Pass-through Digital output is available to Windows Vista(SP1) and Mac OS-X only.
