The dual mono structure processes stereo signals with higher purity, and the D\/A converter section uses one ESS Technology ES9038 Q2M in each of the left and right channels.\u003cbr\u003e\u003cbr\u003eThis model achieves a high signal-to-noise ratio by using each DAC in mono mode.\u003cbr\u003eMoreover, we upgraded it with high specifications that enable native playback of\u003cbr\u003e22.5MHz DSD and 768kHz\/32bit PCM formats. In the analog processing section,\u003cbr\u003ewhich can be considered the key to audio quality, we include four TEAC-HCLD2 circuits. These are improved versions of our previous TEAC-HCLD. For headphone output using the newly-adopted diamond buffer circuit, in addition to two standard 6.3mm connectors, one 4.4mm 5-pole headphone connector is available, enabling balanced connection and active ground connection with a single plug.\u003cbr\u003e\u003cbr\u003eThe Bluetooth® receiver supporting LDAC™ and Qualcomm® aptX HD™ allows you to enjoy high-quality wireless audio streaming from your smartphone on this reference USB DAC.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eESS Technology ES9038 Q2M high-performance DAC supports resolutions up to 22.5MHz DSD and 768kHz\/32bit PCM\u003c\/strong\u003e\u003cbr\u003eWe have employed one DAC chip, which is a crucial component for digital audio, in each of the stereo channels. The ESS Technology ES9038Q2M SABRE32 Reference DAC that we use has a strong reputation in the high-end audio market. Using 32-bit HyperStream® II DAC architecture and Time Domain Jitter Eliminator, which are ESS original technologies, an outstanding dynamic range is realized and linearity is increased in the D\/A conversion. As a result, clear and accurate audio playback with superior.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eDual monaural circuit design and fully-balanced design\u003c\/strong\u003e\u003cbr\u003eA dual monaural circuit configuration is used throughout, from the power supply (including power transformers), to the D\/A converters in the digital section and the Analog output stage. From the high-performance D\/A converters to the massive toroidal-core power transformers, each element is configured for single channel processing. This prevents mutual interference effects while reproducing a rich acoustic expressiveness. In addition, the Analog audio signals of both the left and right channels are processed in full balanced mode soon after the D\/A converters all the way to the output terminal, contributing to an improved S\/N ratio and extended dynamic range.\u003cbr\u003eThis allows the fantastic sense of air that Hi-Res formats possess to be processed and conveyed without any losses.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eHigh-quality wireless audio streaming via Bluetooth®\u003c\/strong\u003e\u003cbr\u003eIn addition to conventional SBC and AAC codecs, the UD-505-X also supports LDAC™ (24bit\/96kHz Hi-Res audio transmission), and Qualcomm® aptX™ HD, a codec that uses 24bit\/48kHz format transmission. These allow you to playback playlists on your smartphone and tablet wirelessly.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eDual onboard clocks for 44.1kHz and 48kHz, and an external clock input\u003c\/strong\u003e\u003cbr\u003eInstead of referencing to an unstable and noisy PC clock during USB audio playback, a more accurate and on-board clock is generated by a high-precision, low phase-noise, audio-grade crystal oscillator for USB asynchronous transfer mode. The UD-505-X accommodates two on-board clocks exclusively for 44.1kHz and 48kHz sampling frequencies and applies the appropriate one to incoming digital signals - those that are multiples of 44.1k or 48k - to reproduce identical sound to the original by eliminating jitter effects on the audio signal.\u003cbr\u003eIn addition, an external 10MHz clock input is also provided, to synchronize with an even higher-precision master clock generator, such as the TEAC CG-10M\/CG-10M-A, for yet further upgraded audio playback with excellent sound quality.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eUp-conversion up to 384kHz\/32bit PCM and 24.5MHz DSD\u003c\/strong\u003e\u003cbr\u003eEmploying RDOT-NEO (Refined Digital Output Technology NEO), a fluency algorithm that renders digital audio signals smoothly, the UD-505-X up-converts PCM digital signals up to 384kHz\/32bit PCM and 24.5MHz DSD. With the up-conversion function activated, you will hear an improvement in quality, even with music that you are familiar with.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003e\"Bulk Pet\" USB transfer technology for enhanced audio quality\u003c\/strong\u003e\u003cbr\u003eWhen transferring large volumes of digital data for Hi-Res audio sources through USB cables using conventional isochronous transfer mode, large variations can occur in the processing loads of the sending computer and the receiving USB DAC.\u003cbr\u003eThis can cause sound to drop out and other problems to occur. However, with our new USB transmission technology – dubbed \"Bulk Pet\" – a fixed amount of data is transmitted constantly, levelling out the processing burden on both devices and contributing to stable data transmission.\u003cbr\u003eChanging the processing burden on the computer directly affects audio quality so users can select the setting they prefer (from four transmission modes).\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eSeven types of PCM digital filter\u003c\/strong\u003e\u003cbr\u003eSeven types of PCM digital filters are available in this model. This allows you to choose the best filter according to the input file format and music style. Since the filter can be changed with a single operation of the included remote control, you can easily enjoy the differences in the subtle sound nuances of each filter type. The unit can also be used with no enabled filters.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eDual high-capacity toroidal-core power transformers\u003c\/strong\u003e\u003cbr\u003eThe dual monaural theme continues. Two over-sized high-capacity toroidal-core power transformers are employed in the UD-505-X, supplying stable, individual current sources for each of the left and right channels. This means neither channel will be affected by changes in the power consumption of the other during digital processing.\u003cbr\u003e\u003c\/p\u003e\n\u003ch5\u003eSpecs\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eSupported formats\u003c\/strong\u003e \u003cbr\u003eUSB input \u003cbr\u003ePCM 16\/24\/32 bit\u003cbr\u003e44.1k\/48k\/88.2k\/96k\/176.4k\/192k\/352.8k\/384k\/705.6k\/768k Hz\u003cbr\u003eDSD 2.8M\/5.6M\/11.2M\/22.5M Hz\u003cbr\u003eCoaxial digital input \u003cbr\u003ePCM 16\/24 bit\u003cbr\u003e32k\/44.1k\/48k\/88.2k\/96k\/176.4k\/192k Hz\u003cbr\u003eDSD 2.8MHz(supported with 176.4kHz\/24-bit DoP format)\u003cbr\u003eOptical digital input \u003cbr\u003ePCM 16\/24 bit\u003cbr\u003e32k\/44.1k\/48k\/88.2k\/96k\/176.4k\/192k Hz\u003cbr\u003eDSD 2.8MHz(supported with 176.4kHz\/24-bit DoP format)\u003cbr\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDAC section\u003c\/strong\u003e \u003cbr\u003eUSB DAC ESS Technology ES9038 Q2M ×2\u003cbr\u003eUp-conversion up to 384kHz\/32-bit PCM, 24.5MHz DSD\u003cbr\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAudio inputs\u003c\/strong\u003e \u003cbr\u003eUSB USB B port, USB 2.0, asynchronous mode transfer, bulk transfer\u003cbr\u003eCompatible Software TEAC HR Audio Player (Windows, Macintosh)\u003cbr\u003eCOAXIAL digital (rear) RCA pin ×1 (gold-plated)\u003cbr\u003eInput level 0.5Vp-p\u003cbr\u003eInput impedance 75Ω\u003cbr\u003eOptical digital (rear) TOS-link ×1\u003cbr\u003eInput level -24.0 to -14.5dBm peak\u003cbr\u003eCoaxial digital (front) 1\/8” (3.5mm) mini* ×1 (combined with optical digital input, detected automatically)\u003cbr\u003eInput level 0.5Vp-p\u003cbr\u003eInput impedance 75Ω\u003cbr\u003e* 1\/8” Mini -
