精巧甜美的TEAC UD-503 DAC/耳擴

Features :
*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
