The "UD-503" has a compact enclosure of A4 size, it is the result of 60 years cultivated of TEAC know-how in audio, it is a Dual-monaural USB DAC headphone amplifier with a high-end audio concept.
FEATURING:
  • USB DAC that supports 11.2MHz DSD and 384kHz/32-bit PCM
  • Dual-monaural circuit structure used from the power supply to the digital and analog sections
  • Both left and right channels have their own high-end AK4490 DACs, which are made by Asahi Kasei Microdevices Corporation
  • Two high-capacity toroidal core power transformers—one each for left and right channels
  • Isolation circuit that completely separates the digital and analog sections electrically
  • 4 TEAC HCLD buffer amplifiers, which are current-enhancing output buffer circuits, are used for the line amplifiers
  • Up-conversion to formats up to 12.2MHz DSD and 384kHz/32-bit PCM using an FPGA (programmable IC) that utilizes a fluency function
  • Two types of DSD filter and four types of PCM digital filter, as well as an OFF mode
  • 10MHz external clock input supported (available during USB asynchronous transmission)
  • Two high-precision internal clocks—one each dedicated to 44.1kHz and 48kHz signals (available during USB asynchronous transmission)
  • One pair of RCA analog unbalanced inputs
  • Volume output can be set to fixed, fixed +6dB or variable for the one pair of XLR analog balanced outputs and one pair of RCA analog unbalanced outputs
  • XLR jack polarity can be set (2 HOT or 3 HOT)
  • TEAC QVCS high-precision volume circuit
  • Large digital volume display with excellent visibility and remote control with one-button operation of various functions
  • OELD display shows input signal type and various settings (with 3-level dimmer and off functions)
  • Fully-balanced drive headphone amplifier with discrete construction and maximum output of 700 mW + 700 mW
  • Headphone amplifier can be switched among 3 drive types: unbalanced, balanced and active ground
  • Digital inputs on the back include one USB, one coaxial and one optical
  • Combined coaxial mini/optical mini digital input connector on front is convenient for digital input from portable devices
  • Low power consumption design and automatic power saving function meet modern expectations
  • The full-metal body realizes both vibration control and elegant style in an A4-size body that enables placement on a desktop
  • TEAC original design for three-point support using pinpoint feet with attached bases
  • Compliant with RoHS
  • Returns Not Accepted
