It handles DSD up to 22.5 MHz and PCM up to 384 kHz\/32 bit and includes an MQA Full Decoder.\u003c\/p\u003e\u003ch4\u003eD\/A Conversion\u003c\/h4\u003e\u003cp\u003eThe proprietary TEAC Reference Discrete DAC (TRDD 5) processes incoming digital signals at 64 bit\/512 Fs via a delta-sigma modulator in the FPGA and converts them to analog through 16 elements per channel. DSD signals are processed directly, while PCM signals are first converted to a 1-bit signal. Two operating modes can be selected: multi-bit delta-sigma method or 1-bit delta-sigma method.\u003c\/p\u003e\u003ch4\u003eClock and USB Transfer\u003c\/h4\u003e\u003cul\u003e\u003cli\u003eInternal clocks for the 44.1 kHz and 48 kHz series with low-phase-noise crystal oscillators\u003c\/li\u003e\u003cli\u003eExternal 10 MHz clock input (BNC)\u003c\/li\u003e\u003cli\u003eUSB Asynchronous Transfer Method to synchronize with the internal crystal oscillator\u003c\/li\u003e\u003cli\u003eBulk Pet USB transfer technology with four preset transfer modes\u003c\/li\u003e\u003c\/ul\u003e\u003ch4\u003eConstruction\u003c\/h4\u003e\u003cul\u003e\u003cli\u003eDual-mono design with separate L\/R channels throughout the analog output section\u003c\/li\u003e\u003cli\u003eFully balanced signal transmission from the D\/A converter to the output stage\u003c\/li\u003e\u003cli\u003eTwo toroidal core transformers, one each for the analog and digital boards\u003c\/li\u003e\u003cli\u003eFeedback-free circuit in the analog power supply section\u003c\/li\u003e\u003cli\u003eFloating-mounted transformer, Stressless Feet v2 and a 2.8 mm thick top plate for vibration control\u003c\/li\u003e\u003c\/ul\u003e\u003ch4\u003ePreamplifier and Inputs\u003c\/h4\u003e\u003cul\u003e\u003cli\u003eAnalog volume control via TEAC-QVCS (Quad Volume Control System) in 0.5 dB steps\u003c\/li\u003e\u003cli\u003eTEAC-HCLD2 enhanced-current output buffer circuits\u003c\/li\u003e\u003cli\u003e2 digital inputs coaxial and optical, 2 line inputs (RCA and XLR)\u003c\/li\u003e\u003c\/ul\u003e\u003ch4\u003eHeadphone Amplifier\u003c\/h4\u003e\u003cp\u003eThe dedicated headphone amplifier uses four diamond buffer circuits and allows connection of balanced headphones.
