Voltage can be 22-24V
24V is best
Current can be 1A~4A
Lithium battery pack, regulated power supply, or high-quality switching power supply can be used
Standard version
updated version
Note: The power supply requires DC 18~24V, and the plug adopts 5.5*2.1MM.
Upgraded version, (special version decoding is optimized in both digital and analog circuits, and carefully crafted with better sound chips, using beautiful sound components and special parameters to combine the human voice, mid-frequency luster, and transparency on the sound , The charm, musicality and other aspects have been significantly improved.)
Decoder length 88mm width 58mm thickness 38mm
The PCM56 decoder chip is an early classic R2R chip with very good quality. Through careful design and selection of materials and production, let it bring you an unexpected and refreshing sound experience.
After ingenious design and processing, the decoder only needs to input one set of DC power supply to achieve multiple sets of voltage supply. The four-layer circuit board design greatly reduces the size of the machine, and achieves exquisite, compact, convenient, portable, beautiful, The goal of integrating beautiful sound, small size but extremely high sound quality and sense of hearing, sound feeling is very good, natural, good density, balanced, good analytical ability, sound is very transparent, clear and smooth, high, middle and low tri-band connection And the continuity is excellent. The low frequency is fast and full of flexibility, the sound is full of energy, and the vocal analysis is very high, but it has the obvious texture of the analog era, and it is not greasy to listen to it for a long time It not only has the analytical power and tri-band performance of the late high-index decoding chip, but also the musical sense of the early R2R chip and the sound characteristics of real and natural simulation.
Having a high-quality and beautiful-sounding R2R decoder was something you could do before at a high price. Now you can do it with just over a hundred yuan. It&x27;s really worth the excitement of audiophiles and music lovers. Thing
Support format: CD format (WAV 16bit 44.1K)
This decoder is not sensitive to power, and the sound is very good with a better quality switching power supply (the ones on the market are tens of dollars), and there is no need to buy those expensive so-called line power.
