L1541DAC Gold TDA1541 DAC Decoder Support Coaxial and Optical Fiber Input new

Description: Description L1541DAC Gold TDA1541 DAC Decoder without TDA1541 and 7220 Chips Support Coaxial and Optical Fiber Input Features: - Power supply: Four high-quality sealed transformers are used to strictly distinguish digital power supply, decoding chip power supply, and LPF power supply. For the two negative voltages (-5V, -15V) of the TDA1541 chip, two transformers are used to avoid the introduction of LPF power supply loop- 15V causes cross interference. - Five groups of parallel stabilized power supply: Decoding details and dynamics are fully utilized. There are many controversies for various power supply circuits, but the shortcomings of shunt voltage stabilization are low efficiency and high cost. The quality is definitely higher than any series voltage stabilization. Its internal resistance, ripple, transient response time and other voltage stabilization The circuit is not on the same level. - MCU soft-controlled digital receiving: Microcomputer dynamically optimizes parameters, and adjusts the phase detector of the receiving chip (CS8416) to make it automatically adapt to the input bit rate and minimize jitter. - Indispensable digital filter: In a word, any TDA1541 decoder that does not use SAA7220 digital filter is no longer has the sound of 1541. - Well-designed two-stage LPF circuit: This decoder uses four single op amps to complete a two-stage LPF low-pass circuit. This is a very important design, and its drive capability and LPF circuit characteristics are guaranteed. - The detail design is also intimate: many details determine success or failure, and the details of this decoder are not compromised. Simple operation and one-stop layout, even if the dual capacitors of the coupling output are placed in the position (for tuning), it can also reflect incomparable Attentive. Design changes in the later tuning: - The SFC11F02E microcontroller with internal storage is upgraded, and the working state of the monitoring program storage and decoding adopts a more stable internal flash memory. Therefore, the external 24C02 flash memory does not need to be soldered (the small chip in the SOP8 packaged on the right side of the MCU), and the kit is no longer Matching. - There are two 1N capacitors in the LPF part, changed for Epcos 2N2. - The output coupling part adopts for nichicon MUSE 47uf stepless capacitors or for Philips axial fever capacitors, which are shipped randomly, or can be specified, canceled the original for Wima parallel ELNA design. Parameters: - Digital input: coaxial, optical fiber, USB (it need to buy the L2706USB separately) - Analog output: RCA analog output - Digital input bit rate: 16bit, 44.1K 48K - Analog output level: 2Vrms - Power supply: AC220V - Size: 220 x 52 x 191mm - Weight: 2.7kg Package Included: - 1 x Decoder Payment Terms 1.
