TEACUSB-DAC/Network Player (Black)TEACUD-701N-BScheduled for release on May 29, 2021Manufacturer's warranty period: 1 yearThe TEAC UD-701N is an all-rounder that can flexibly adapt to new listening styles in a new era. Newly developed TEAC Delta-Sigma discrete DACThe new TEAC Delta-Sigma discrete DAC does not use a general-purpose DAC IC, but uses a discrete circuit with an FPGA that incorporates a unique algorithm.DSD is retained, while PCM is converted to a 1-bit signal through a ΔΣ modulator and then output as a high-quality analog signal.The vast and clear sound field expression that can only be achieved with a discrete DAC is the ultimate in sound that TEAC has been seeking.The TEAC ΔΣ discrete DAC is capable of reproducing DSD 22.5MHz and PCM 384kHz/32bit. Dual Monaural ConfigurationA luxurious dual monaural configuration has been adopted, from the power supply circuit with a toroidal-core transformer mounted independently on the left and right sides, to the D/A converter section and analog output stage.The dual monaural configuration, with two complete monaural circuits for each channel, prevents interference from L/R signals and realizes rich musical expression such as a sense of sound field and three-dimensionality. Fully balanced transmission in all stagesFull-balanced transmission of the L/R analog output signals from the D/A conversion to the final output stage greatly contributes to the improvement of S/N and the expansion of dynamic range.This contributes greatly to improving S/N and expanding dynamic range, and conveys the full atmosphere of high-resolution sound sources in a more pure state. Four large-capacity toroidal-core transformersIn addition to two independent toroidal-core transformers for analog signals on the left and right sides, independent toroidal-core transformers are provided for the network module section and digital control section.In addition to the two toroidal-core transformers independently mounted on the left and right sides for signals, independent toroidal-core transformers are provided for the network module section and digital control section. In particular, the power supply for the network module section is reinforced with a linear power supply to provide stable power to the network module, which requires advanced processing. Analog preamplifier function with four digital inputs and two line inputs (RCA/XLR)In addition to its functions as a USB DAC and network player, it is equipped with two digital inputs each for coaxial and optical digital, as well as RCA and XLR analog inputs, allowing it to be used as a high quality analog preamplifier in combination with external devices. The TEAC-QVCS (Quad Volume Control System), which uses a variable gain amplifier type volume with four independent circuits for left and right, positive and negative (L+, L-, R+, R-), is placed on the audio signal path to minimize the signal path and prevent degradation of the audio signal due to the routing of signal lines.The Quad Volume Control System (QVC) is placed on the audio signal path to minimize the signal path and prevent audio signal degradation due to signal line routing. The TEAC-HCLD 2 circuit is a brushed-up output buffer amplifier with enhanced current transmission.The TEAC-HCLD 2 circuit is a further improved version of the TEAC-HCLD (HCLD: High Current Line Driver) circuit, which enhances the current transmission capability that is important for analog output circuits.The diamond buffer amplifier, which has a high current-carrying capacity, is configured as a line driver with two positive and two negative circuits per channel, driven differentially for balanced output and in parallel for unbalanced output.By increasing the current supply capacity, the dynamism of the music signal can be conveyed in its entirety. Headphone amplifier with 4-pin XLR with switchable balanced/active groundA dedicated headphone amplifier with four diamond buffers, one for each positive and negative sides, enables the connection of balanced headphones.In addition, even when used in single-ended mode, these amplifiers are driven in parallel to provide a more powerful drive than a normal single-ended headphone amplifier.Even when used in single-ended mode, these amplifiers are driven in parallel to provide a more powerful drive than a normal single-ended headphone amplifier, enabling the potential of a wide range of headphone types, including high-impedance 600Ω headphones, to be brought out. The active ground method is a drive method that uses the principle of balanced connection to connect the COLD side to ground, forcing the amplifier circuit to drive the ground closer to 0V.This not only provides a more ideal ground than dropping to normal ground, but also suppresses the effects of hum noise coming from the power supply, and with the noise floor lowered, it increases quietness and allows you to feel the breath of the artist and the texture of the sound more closely. Full MQA decoder compatible with CD player digital outputMQA (Master Quality Authenticated) is a high quality audio codec for reproducing studio master quality audio as it really is.The UD-701N is equipped with an MQA decoder that controls the D/A converted waveform with a precision of 5 microseconds to obtain an analog waveform that is more faithful to the original sound.The MQA decoder controls the D/A-converted waveform with a precision of 5 microseconds. The UD-701N is equipped with a full decoder, which enables not only file and network playback, but also decoding of MQA data from digital inputs, allowing you to connect the digital output of your CD player to the UD-701N for MQA CD playback.
