The latest QCC5125 Bluetooth 5.0 module.At the same time, it supports for -HD or LDAC, which adds a lower latency protocol for -ll compared to CSR8675 4. USB DAC solution compatible with digital interface for Amanero,The USB DAC solution is ATSAM3UxC, and we have rewritten the CPLD code to adapt to MD2,The driver is compatible with digital interface for Amanero. For Linux, , mobile phones, no driver is required. 1. Optical input MD2 optical fiber is designed as an input, which greatly facilitates to connect , set-top boxes, CDs and other audio sources. Abandoning AK4118, it uses CS8416 which is very easy to lock frequencies, the focus is on the slave mode, CPLD + crystal oscillator are used to avoid the I2S signal jitter of CS8416. 2. Coaxial output supports DSD signal is transmitted through your coaxial cable. But at the same time you need a decoder to support . Compared with MD1, MD2 upgrades the coaxial to PCM384K DoP128. 3. MD2 contains two ES9038Q2M chips, one ES9038Q2M per channel 4. Equipped with a remote control, it is convenient to switch remotely on the sofa Model:MD2 Display:OLED 0.96inch Bluetooth solution:QCC5125 Bluetooth protocols:For LDAC & -HD USB DAC solution:support for Amanero USB DAC parameters:PCM384K, DSD256 Coaxial:PCM384K, DoP128 (output) Optic fiber:PCM 192K (input) Colour:Black & Silver Material:Metal Size:28x84x92mm Package Contents: 1 x Player Decoder Host 1 x Antenna 1 x USB Cable 1 x Remote Control(2 AAA batteries not included) Only the above package content, other products are not included.
