Dual-monaural USB DAC
Dual-monaural USB DAC that supports 11.2MHz DSD with built-in fully-balanced/parallel-unbalanced headphone amplifier
Features at-a-glance
- 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
