Newly-developed TEAC ΔΣ (Delta Sigma) discrete DAC
Instead of using a generic DAC IC, we incorporated a newly-developed TEAC ΔΣ (Delta Sigma) discrete DAC comprised of discrete circuitry that uses FPGA incorporating our original algorithms. Analog signals are output with high audio quality. DSD signals are transmitted as is, while PCM signals are transmitted after passing through a ΔΣ modulator and conversion to 1-bit signals.
We can say that achieving this wide, perfectly clear sound field, which can be realized specifically because of the discrete design, is TEAC reaching the pinnacle of its sound objectives.
With the TEAC ΔΣ discrete DAC, playback of 22.5MHz DSD and 384kHz/32-bit PCM is possible.

Dual mono structure
We have incorporated an extravagant dual mono structure throughout the unit, from the power circuit with independent left and right toroidal core transformers to the D/A converter section and analog output stage.
This dual model structure, which has complete mono circuits for each of the two channels, prevents interference between the left and right channels, enabling the realization of rich musical expression that reproduces the sense of space and dimension.

Analog preamplifier function with 2 line inputs via RCA/XLR and 4 digital inputs
Not only as a USB DAC/Network player that employs two sets of coaxial and optiocal digitla inputs, the UD-701N also works as a high-quality analog preamplifier by employing additional analog audio inputs via RCA and XLR connectors that allow users to connect conventional audio sources.
Our TEAC-QVCS (Quad Volume Control System) is a variable gain amp volume control with four independent circuits for left, right, positive and negative (L+, L?, R+ and R?). Placing this in the audio signal route makes it as short as possible, preventing the degradation of audio signals caused by drawing them through signal lines. Moreover, since the volume can be adjusted in extremely fine 0.5dB intervals, you can achieve the ideal volume for the audio system or headphones that you are using.

4-pin XLR headphone amplifier that can be switched between balanced and active ground
A total of four diamond buffers, one in each of the left, right, positive and negative circuits, are used in the dedicated headphone amplifier, enabling the connection of balanced drive headphones. Moreover, even during single-end use, by driving these amps in parallel, they can provide stronger drive than ordinary single-end headphone amplifiers. This enables the potential of many types of headphones, including 600Ω high-impedance headphones, to be realized.
Active ground is a drive method, based on the principles of a balance connection, that approaches 0 V by connecting the COLD connector to the ground and driving the ground forcibly using an amplifier circuit. Not only can a more ideal ground be realized than when using an ordinary ground, the impact of humming noise coming from the power can also be suppressed. Moreover, by lowering the noise floor, we can expect silence to be deepened, allowing the breathing of the artists and the texture of sounds to be felt more intimately.

Upconversion
The upconversion function uses RDOT-NEO (Refined Digital Output Technology NEO) to smoothly augment PCM digital audio signals and upconvert their sampling frequencies 2, 4 or 8 times (384kHz maximum). RDOT, which applies an analogous interpolation method using fluency logic, is a technology that was developed to enable reproduction and playback of frequencies higher than 20 kHz that are lost by 44.1kHz/48kHz digital signals. Based on the information read, analogous data is generated between the waveform samples, which also results in data above 20 kHz.

Bluetooth® receiver supports LDAC, aptX™ HD and other high-resolution transmission formats
In addition to the LDAC™ and LHDC codecs, which can transmit audio data with quality that is considered high resolution (96kHz/24-bit), it also supports Qualcomm® aptX™ HD, which is capable of 48kHz/24-bit transmission. Of course, the popular AAC, Qualcomm® aptX™ and SBC codecs are also supported, so you can easily enjoy high-quality wireless playback from smartphones and digital audio players.


Support for popular and convenient network functions, including OpenHome and Roon Ready
Common control apps that support OpenHome can be used with the UD-701N, which also supports this platform. Moreover, playlists on the UD-701N can be managed using TEAC HR Streamer and other control apps that support OpenHome. Gapless playback is also supported.
With support for Roon Ready, functions provided by RAAT (Roon Advanced Audio Transport), including high-quality audio playback, easy and convenient operation using apps, and multi-room synchronized playback, can be used without limits.

Spotify Connect, Tidal, Qobuz, and TuneIn (Internet Radio)
Along with Spotify Connect, this model also supports Tidal and Qobuz, which are subscription music streaming services that enable listening to lossless CD-quality (44.1kHz/16-bit) recordings.
* Tidal Connect will be added in a firmware update made available after product release.


Bulk Pet USB transfer technology enables stable data transmission
When transmitting large amounts of digital data by USB cable from high-resolution audio sources, large inconsistencies arise in the processing loads of both the sending computer and the receiving USB DAC, and audio dropouts and other problems can occur. Using the Bulk Pet USB transfer technology, however, the same amount of data is transmitted at a steady rate, leveling the processing loads of both sides and realizing stable data transmission. Since changes in computer load conditions can also affect audio quality, you can select from four preset transmission modes to choose the preferred audio quality.
