AD1865R NOS Audio DAC Decoder Board Coaxial Input AK4118 24BIT 192KHZ Dual Parallel R2R DAC Equivalent to TDA1541 PCM63

Feature: Product Name: Dual and R2R Decoding AD1865R NOS DAC Size: 130*95mm Signal input: 1, coaxial (SPDIF) 2, I2S Voltage input: AC double 15v group, exchange single 9v group Signal receiving chip: ak4118 Power module: adopts JRC low noise voltage regulator module Signal support format: coaxial support pcm format, up to 24 bits 192khz. I2S supports for Philips I2S, xmos interface, Italian interface, etc. Bluetooth module with I2S output, only need to connect BCK LRCK DATA three pins. Decoder board technical parameters: Dual AD1865R composed of mono architecture, choose the chip internal op-amp. Direct current output with external IV circuit, and lpf circuit, with accurate noise cutoff technology to limit out-of-band noise, with a very dark sound background, use nos way to access digital signals, with the original original taste and completeness to restore the sound Resolutely discarding the external filter chip, in addition to the high-reduction sound, also reduces the design cost, this is a stone two birds. Everyone does not know, only after a trial has the right to speak. In addition, the tuning parameters are repeated several times to make the sound more vinyl record style, and the low frequency is powerful, and the TDA1541 PCM63 double decoding and decoding does not lose. The AD1865R is one of the classic R2R DACs. It has a huge amount of money, so the price has an absolute advantage. The weight is promoted, compared with the popular ak4497 ESS9038. Its characteristics are that it doesn't get tired of listening for a long time, and the music is good. The more you listen, the more delicious it is. High resolution, not noisy, relaxed and atmospheric. The low frequency is powerful, supple and not fat. The voice is sweet, not illusory, and the real presence is full. The format of the decoding is from I2S up to 24 384KHZ, which is not inferior to most popular decoder chips. Why launch, but not the flagship chip today. There are two reasons. 1. After the 10 samples are sold, the reaction is quite good. 2. The sound is good (cannot be expressed in words) Package includes: 1 x Decoder board
