The new coaxial decoding board features external 12V power supply, supporting input frequencies up to 48K-192KHZ. It can connect to the coaxial interfaces of various devices such as TV set-top boxes, PS4, and DVD players, and outputs at 2Vrms via RCA, allowing direct connection to an amplifier or active speakers. The product's external power supply is plug-and-play, making it very convenient.
The PCM56 is a classic DAC chip. After extensive listening and comparison, we found that the dual parallel PCM56 circuit we currently have sounds excellent, with clarity and emotional appeal. The actual experience reveals abundant details, clearer soundstage positioning, and more rounded, delicate vocals that are enjoyable to listen to. It is on par with high-end mainstream circuits.
The PCM56 supports signal rates up to 16BIT 48K. This board only has optical and coaxial input ports. The dimensions of the decoding board are 15X20CM. The required power supply is AC 15VX2 7VX2, with each group needing a current of 0.3A or more. This board uses a brand-new PCM56 chip, not a used one.
Additionally, the circuit includes a headphone amplifier driver circuit using the M5218, with JFET input and high current output. Although it's an older operational amplifier, it's no less effective than typical ones, and we use it in several other machines.
This is a finished board, already soldered and tested, ready for use with a power supply.
Power Supply Voltage: One set of AC 12V-0-12V, one set of AC 7V-0-7V.
