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.
Features:
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).
