1794 DualCore Parallel PCM1794 DAC Decoder 192KHz 24Bit Coaxial Optical Upgraded

Description: Description 1794 Dual Core Parallel PCM1794 DAC Decoder 192KHz 24Bit Coaxial Optical Input (Upgraded Version) Description: It is the latest version, with voltage regulator upgraded to 3pcs LT1963 high-end regulators. Version Comparison: - Standard Version: Op amp with 3pcs TL072. - Upgraded Version: Op amp with 3pcs American OPA1612 high precision operational amplifiers. Advantages: - Core PCM1794 decoding. Details, dynamics and sound field are very good - Coaxial and optical input adopt WM8805 demodulation, which is a higher grade than the common CS8416 on the market, with low time base jitter and good compatibility, no popping, and easy transmission of 192K 24BIT data - Using low-distortion op amp OPA1612 low-pass, the effect is better than that of OPA2604. The sound is transparent and delicate, natural and bright. With gold-plated IC socket, you can freely replace and upgrade the op amp - Using resistor-capacitor matching components and linear voltage regulator integration, make the circuit performance fully play. With components for WIMA, capacitors for ELNA, high-quality chip resistors for TDK and the like - Aluminum alloy case with laser lettering is fashionable and durable - Excellent performance with cheap price Features: - PCM1794A dual cores are connected in parallel. 192KHz, 24Bit - 2pcs PCM1794A, each piece is responsible for one sound channel, which greatly improves sound density and separation, the sense of air and sound field is improved! - LT1963 voltage regulator, large current, high precision and low internal resistance. The noise is as low as 20UV, which is an ultra-low ripple of 0.02MV, allowing PCM1794 to work in the most ideal state. - Both I/V conversion and low-pass use OPA1612 dual op amp. OPA1612 (dual channel) bipolar input op amp can achieve very low noise density (1.1nV/√Hz) and ultra-low distortion (0.000015%) at 1kHz. The OPA1612 can provide rail-to-rail output with a swing range of 600mV from the power rail under a 2-k load, which helps to maximize the dynamic range. Performance surpasses that of LME49720 and LME49710 - Hermetic transformer boasts low magnetic leakage and high efficiency. It is the most basic guarantee for the sound of the whole machine. Next to it is the high-speed filter capacitor for Panasonic for FC audio Rear Panel Introduction: - OUTPUT (R, L): Stereo sound output - COAX: Coaxial input - OPT COAX: Coaxial/Optical switching - OPTICAL: Optical input - With an AC power supply input port About Burn In: - For HIFI speakers, we recommend a burn-in time of 96 hours. The recommended burn-in time for equipment such as amplifiers and decoders is 24 hours - Burn-in method: The cumulative use time of normal music reaches the burn-in time. Specifications: - Input mode: coaxial + optical fiber - Output mode: RCA terminal - THD+N: 0.002% - SNR: 115DB - Dynamic range: 118DB - Frequency response: 15-30KHZ - Output voltage: 2.5V - Machine size: 169 x 116 x 54mm (LxWxH) Package Included: - 1 x Set of DAC Note: - It is assembled and ready to use.
