Teac UD-505 overview

  • 1Description

The black Teac UD-505 is a dual-mono USB DAC with a built-in headphone amplifier offering flexible connectivity, high-resolution audio, and precise performance for audiophiles and demanding listeners. Its discrete dual-mono design incorporates isolated analog and digital sections as well as per-channel converters, buffer amps, and toroidal-core transformers. Dual onboard clocks provide stable operation at an array of sample rates, while a BNC external clock input accommodates synchronization to a dedicated master clock (available separately). The UD-505 supports PCM playback up to 32-bit / 768 kHz, and DSD playback up to DSD512 (22.5 MHz).

Stream music wirelessly in LDAC, aptX, aptX HD, AAC, or SBC codecs from a mobile device to the built-in Bluetooth receiver. Connect analog and digital sources via the RCA, USB, coaxial, and optical inputs, and select your desired input using the front-panel input knob or the supplied remote control. The selected input and more will be shown on the high-contrast OLED screen. XLR and RCA outputs allow easy hookup to speakers while the 1/4" TRS and Pentaconn headphone outputs facilitate connecting balanced or unbalanced headphones.

High-Performance DACs
The UD-505 employs VERITA AK4497 (developed by Asahi Kasei Microdevices) on each of the left and right channels. It supports DSD512 (22.5 MHz) and 32-bit / 768 kHz PCM formats, achieving ultra-low distortion levels. Also, OSRD (Oversampling Ratio Doubler) technology significantly reduces out-of-band noise.
Dual-Mono Circuit Design
A 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 VERITA AK4497 D/A converters to the large toroidal-core power transformers, each element is configured for single-channel processing to prevent mutual interference effects.

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 signal-to-noise ratio and extended dynamic range.
Audio Streaming via Bluetooth
In addition to conventional SBC and AAC codecs, the UD-505 also supports LDAC (24-bit / 96 kHz Hi-Res audio transmission) and Qualcomm aptX HD, a codec that uses 24-bit / 48 kHz format transmission. These allow you to playback playlists on your smartphone and tablet wirelessly while maintaining high-quality resolution.
Dual Onboard Clocks
Instead of referencing an unstable and noisy PC clock during USB audio playback, a more accurate clock is generated by an onboard high-precision, low phase-noise, audio-grade crystal oscillator for USB asynchronous transfer mode. The UD-505 accommodates two onboard clocks exclusively for 44.1 kHz and 48 kHz sampling frequencies, and applies the appropriate one to incoming digital signals to reproduce identical sound to the original by eliminating jitter effects on the audio signal.

In addition, an external 10 MHz clock input is provided to synchronize with an even higher-precision master clock generator (available separately) for yet further upgraded audio playback quality.
Up-Conversion
Employing RDOT-NEO (Refined Digital Output Technology NEO), a fluency algorithm that renders digital audio signals smoothly, the UD-505 up-converts PCM digital signals to 32-bit / 384 kHz PCM and 22.5 MHz DSD.
Enhanced USB Transfer Technology
When 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. This can cause sound to drop out and other problems to occur. By incorporating "Bulk Pet" USB transmission technology, the UD-505 is able to constantly transmit a fixed amount of data, leveling out the processing burden on both devices and contributing to stable data transmission. Changing the processing burden on the computer directly affects audio quality; users can select their preferred setting from four transmission modes.
Selectable Digital Filters
On the UD-505, there are two types of DSD filters and five types of PCM digital filters, allowing you to apply the filter that best matches the file format or type of music you're listening to. The filter can be changed at the touch of a button on the remote control, allowing you to enjoy the different sonic nuances of each filter.
Isolated Digital and Analog Sections
In order to suppress interference between the digital and analog sections, the UD-505 employs an independent power supply and ground circuit, thereby eliminating cross-interference in the signal path where digital and analog sections connect. A digital isolator is employed at the input section to eliminate noise originating from any connected digital sources, including noise that is generated from the computer via USB, power line, and the ground path. This isolation circuit also improves the signal-to-noise ratio.
Toroidal-Core Power Transformers
Two oversize high-capacity, toroidal-core power transformers are employed in a dual-mono configuration, 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.
Output Buffer Amplifiers
At the heart of analog section are TEAC-HCLD (High Current Line Driver) buffer amp circuits, designed to enhance current supply. Each channel employs two identical buffer amps that process differential drive for balanced output, and parallel drive for unbalanced output. By increasing the current supply to the buffer amp section, the analog audio signal is passed to the next step without any loss of dynamism.
High-Precision Volume Control
The TEAC-QVCS (Quad Volume Control System) is a precise volume control design incorporated in the preamp section. This circuit employs four sets of variable gain-amps controlling volume for left, right, positive, and negative (L+, L-, R+, R-). Each variable gain-amp is located on a simplified signal path, which helps eliminate interference noise by creating a shorter signal path. In addition, the TEAC-QVCS provides precise volume control in 0.5 dB steps in "dB" display mode, or 100 steps in "step" display mode.
Front-Panel OLED Screen
A high-contrast, full-dot OLED with a four-step dimmer is employed to deliver consistent visibility. Also, a large font size allows you to easily verify the volume level, input source, and other information, even when sat at a distance.
Pentaconn and 1/4" Headphone Outputs
In addition to the dual conventional 1/4" TRS jacks for balanced connection, the UD-505 employs a newly designed single headphone jack for balanced drive. The Pentaconn jack is a 4.4mm 5-pole jack that has been developed by NIPPON DICS Co., Ltd, and complies with the RC-8141C JEITA Standard, providing a single-jack solution for balanced headphones.
Sturdy Construction
Just as with the Reference 503 series, the UD-505 employs aluminum-alloy panels and a robust metal chassis with a compact A4-size footprint that matches with the 500 series and CG-10M master clock generator. The full metal construction is also effective at isolating the internal circuits from electromagnetic noise.
Versatile I/O
The UD-505 is equipped with both balanced and unbalanced analog audio outputs. Gold-plated XLR and RCA connectors are symmetrically arranged with wide spacing to accommodate plugs with large-diameter shells. The UD-505 has a total of five digital inputs—USB audio, separate coaxial and optical sockets on the rear panel, and a 3.5mm coaxial/optical combination jack on the front panel. A pair of RCA analog audio input connectors allow the UD-505 to function as a pre-amplifier equipped with a precision volume control (TEAC-QVCS).
Stable "Pin-Point" Feet
The UD-505 employs TEAC's patented "Pin-Point" feet. Each is comprised of two separated metal sections in an integrated housing. One has a spiked top and is attached to the bottom of the chassis, while the other is a basin-shaped base that hangs down from the spiked section with a flange-shaped cup to simply installation.

Three "Pin-Point" feet are used for support, two at the front and one at the rear, for excellent stability and flat or uneven surfaces. As a result, the three "Pin-Point" feet help improve the accuracy of clock oscillation by minimizing vibrations and resonance. This, in turn, reduces mid- and low-frequency muddiness, improves the soundstage, and enhances sonic details.
TEAC HR Audio Player Software
The next-generation Hi-Res formats, DSD512 (22.5 MHz) and PCM 32-bit / 768 kHz are supported via the TEAC HR Audio Player software for Mac and Windows. This software delivers uncompromising playback quality with any combination of audio format and computer configuration via a single USB cable. All the user has to do is choose the UD-505 from the pull-down menu showing target output devices. The TEAC HR Audio Player is available from TEAC's web site, and is completely free to use.
