Serving as an entry point into high-fidelity R-2R audio, the ERATO features a true balanced 24-bit R-2R architecture paired with a 6-bit DSD resistor network utilizing hand-matched 0.005% ultra-precision resistors.\u003c\/p\u003e\n\n\u003cp\u003eHoused in a CNC-machined solid aluminum unibody chassis, the ERATO integrates an FPGA digital signal processing engine with dual FEMTO crystal oscillators (45.1584 MHz \/ 49.152 MHz) and adaptive FIFO buffering for low-jitter signal reconstruction. Power is supplied by an internal linear power supply featuring a custom 60 VA O-core shielded transformer. Its proprietary USB receiver—powered by an STM32F446 ARM Cortex-M4 MCU—supports extreme decoding rates up to PCM 1536 kHz and native DSD1024. Remote control operation is supported via the optional DN-Y3 infrared remote.\u003c\/p\u003e\n\n\u003ch3\u003eKEY FEATURES \u0026amp; PROPRIETARY TECHNOLOGIES\u003c\/h3\u003e\n\n\u003cul\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eTrue Balanced Discrete R-2R + DSD Network:\u003c\/strong\u003e Utilizes hand-matched 0.005% low-thermal-effect resistors across a balanced 24-bit R-2R ladder and a 6-bit DSD FIR filter network.\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eFPGA Processing \u0026amp;
