footprint.\u003c\/p\u003e\n\u003cp\u003eThe UD-505-X is a class-leading dual monaural USB DAC with an integrated fully-balanced headphone amplifier that fuses high-end audio design concepts and TEAC’s decades of audio design experience in an A4-sized footprint. 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.\u003c\/p\u003e\n\u003cp\u003eThis model achieves a high signal-to-noise ratio by using each DAC in mono mode. Moreover, we upgraded it with high specifications that enable native playback of 22.5MHz DSD and 768kHz\/32-bit PCM formats. In the analog processing section, which 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.\u003c\/p\u003e\n\u003cp\u003eThe Bluetooth® receiver supporting LDAC™ and Qualcomm® aptX HD™ allows you to enjoy high-quality wireless audio streaming from

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. This allows the fantastic sense of air that Hi-Res formats possess to be processed and conveyed without any losses.\u003c\/p\u003e\n\u003ch3\u003eHigh-quality wireless audio streaming via Bluetooth®\u003c\/h3\u003e\n\u003cp\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.

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 44.1 or 48 kHz - to reproduce identical sound to the original by eliminating jitter effects on the audio signal. In 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.\u003c\/p\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cstyle data-emotion-css=\"6g863v\"\u003e\u003c\/style\u003e\n\u003cdiv class=\"builder-block builder-9ce46c06d3634ffd92f6812e71729e91 builder-has-component css-6g863v\" builder-id=\"builder-9ce46c06d3634ffd92f6812e71729e91\"\u003e\u003cdiv class=\"builder-columns css-1840m1q\"\u003e\n\u003cdiv class=\"builder-column css-2keume\"\u003e\u003cdiv class=\"builder-blocks builder-blocks-child css-h47494\" builder-type=\"blocks\"\u003e\u003cdiv class=\"builder-block builder-78f10bfb336646f1bb47e9b508b5a0e3 builder-has-component css-hgfgng\" builder-id=\"builder-78f10bfb336646f1bb47e9b508b5a0e3\"\u003e\u003cspan class=\"builder-text css-1qggkls\"\u003e\u003ch3\u003eUp-conversion up to 384kHz\/32bit PCM and 24.5MHz DSD\u003c\/h3\u003e\n\u003cp\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.

This 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. Changing the processing burden on the computer directly affects audio quality, so users can select the setting they prefer (from four transmission modes).\u003c\/p\u003e\u003c\/span\u003e\u003c\/div\u003e\u003c\/div\u003e\u003c\/div\u003e\n\u003c\/div\u003e\u003c\/div\u003e\n\u003cstyle data-emotion-css=\"lxerrr\"\u003e\u003c\/style\u003e\n\u003cdiv class=\"builder-block builder-cc133009ce6349b5a4e16a2ccefac0a4 builder-has-component css-lxerrr\" builder-id=\"builder-cc133009ce6349b5a4e16a2ccefac0a4\"\u003e\u003cspan class=\"builder-text css-1qggkls\"\u003e\u003ch3\u003eDual high-capacity toroidal-core power transformers\u003c\/h3\u003e\n\u003cp\u003eThe dual monaural theme continues. Two oversized 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 is a further improved version of the TEAC-HCLD circuit, an enhanced-current output buffer amp that increases crucial current output capacity (HCLD: High Current Line Driver). This model now uses line buffer ICs with extremely high current output capacity. By using a positive-negative two-circuit structure for each channel, the drive can be differential with balanced output and parallel with unbalanced output. Transmitting audio signals without degrading their dynamism becomes possible with increased current supply capacity.\u003c\/p\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cstyle

System) is used for the volume circuit. This electronic volume control is a variable gain amp type comprised of four discrete circuits for left, right, positive, and negative (L+, L−, R+, R−). By placing the variable gain amp volume control, which processes in analog, in the audio signal path on the circuit board, issues with noise resulting from diverging wiring are avoided. Furthermore, this TEAC-QVCS enables volume adjustment in 0.5dB increments, allowing you to set the perfect volume for your audio system or headphones.\u003c\/p\u003e\u003c\/span\u003e\u003c\/div\u003e\u003c\/div\u003e\u003c\/div\u003e\n\u003c\/div\u003e\u003c\/div\u003e\n\u003cstyle data-emotion-css=\"1b2vij7\"\u003e\u003c\/style\u003e\n\u003cdiv class=\"builder-block builder-9c38d56bd2284fe1b985b252749cd8b3 builder-has-component css-1b2vij7\" builder-id=\"builder-9c38d56bd2284fe1b985b252749cd8b3\"\u003e\u003cspan class=\"builder-text css-1qggkls\"\u003e\u003ch3\u003eDesigned to bring out the maximum potential of your headphones\u003c\/h3\u003e\n\u003cp\u003eDiscrete circuit design with balanced drive\u003c\/p\u003e\n\u003cp\u003eThe UD-505-X's headphone amplifier circuit provides balanced drive by using the TEAC-HCLD2 circuit, comprised of four output transistors for each left and right channel, for headphone output.

At the 6.3mm TRS jack, you can enjoy 3 kinds of drive types, an unbalanced connection to drive up to 2 sets of headphones, and an active-ground drive that is effective to improve the silence and present the sensitive sound, as well as a balanced connection.\u003c\/p\u003e\n\u003ch3\u003eActive-ground drive offers a new headphone drive mod.e\u003c\/h3\u003e\n\u003cp\u003eThe active-ground is a new driving mode that employs the principles of balanced connection. It forcefully drives the ground by lowering the ground level to 0V, providing an ideal ground condition (rather than just connecting to the conventional ground). This means it also suppresses hum noise from the power supply and enhances the purity of silent pauses by lowering the noise floor. Subtle details such as the breathing of artists and the textures of sounds will feel even more convincing.\u003c\/p\u003e\n\u003ch3\u003eObsessively well-designed\u003c\/h3\u003e\n\u003cp\u003eFull-metal body for functionality and beauty\u003c\/p\u003e\n\u003cp\u003eSince the entire body is constructed from metal panels that are resistant to external noise, the intrusion of electromagnetic noise generated by computers and other devices is suppressed. A clean internal environment with little noise has been realized even in conditions that are difficult for audio equipment. Furthermore, 8mm-thick aluminum panels covering both sides of the all-metal chassis provide a strong and stable structure that prevents twisting and bending. Moreover, with the size of an A4 page* (viewed from above), the unit can be placed on a desk, side table, or other small space.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003e* This excludes the connectors, knobs, and other protrusions.\u003c\/em\u003e\u003c\/p\u003e\n\u003ch3\u003eSymmetrically laid out XLR and RCA output jacks.\u003c\/h3\u003e\n\u003cp\u003eThe UD-505-X is equipped with both balanced and unbalanced Analog audio outputs. A pair of XLR connectors and another pair of RCA connectors - each gold-plated - are symmetrically laid out, hinting at the dual monaural arrangement inside, and allowing a wide range of possible audio configurations. A wide-spaced pitch layout for the RCA outputs accommodates professional-grade plugs with large-diameter shells. The UD-505-X has a total of 5 digital inputs: USB audio, coaxial, optical on the rear panel, and a combination jack on the front panel (for coaxial and optical, supporting PCM 24bit\/192kHz and DSD64 (2.8MHz) in DoP format).\u003c\/p\u003e\n\u003ch3\u003eNewly developed Stressless Foot design\u003c\/h3\u003e\n\u003cp\u003eOur newly developed original Stressless Foot design with three support points enables stable placement of the unit so that it is not impacted by slight irregularities in the surface beneath it. Compared to the original feet used in previous designs, these feet are only partially fixed to the chassis. This design was developed based on the concept that by allowing the feet to vibrate freely, more natural sound reverberations could be achieved. The tops of the conical feet, which are made of machined steel, are attached so that they hang from the bottom of the chassis and swing freely when the unit is lifted. While maintaining a sense of placement like that of the pinpoint spiked feet used by previous models, this design enables more natural, rich reverberations.\u003c\/p\u003e\n\u003ch3\u003eSemi-floating design Top Panel\u003c\/h3\u003e\n\u003cp\u003eA semi-floating structure is newly used for the top panel.
