Order Case need to tell us your Raspberry Pi model，B+,2B,3B+,3B or 4B
Note
Case needs to be installed by yourself. RCA and optical interfaces are installed in the case and are separated from the coaxial board. The aluminum case needs to weld the signal wire. Please confirm that you have tools and DIY capabilities before ordering.
Bundle difference
Bundle 1: RCA Coaxial +Optical Output
Bundle 2: BNC Balance +Optical Output
Bundle 3: AES Coaxial +Optical Output
Bundle 4: RCA Coaxial +Optical Output +Case
Bundle 5: BNC Balance +Optical Output +Case
Quick Operation Guide
1. After receiving the product, please do not power on and test it immediately. Please connect all signal wires first, then connect the power cord, connect the power cord, then power on, turn on the power and light the switch with its own power indicator (usually blue) Color), you will see the panel PwR (red Raspberry Pi power-on power indicator) (if it is a constant temperature crystal oscillator board, it will take about 20 seconds to warm up before the indicator light.), continue to wait for 5 seconds to left ACT (green channel indicator) The light is flashing.) It proves that it is booting, wait for about 20-30 seconds to complete the boot.
2. Enter the system operation instructions
Power on successfully, enter the router "terminal management" to find the IP named "dhcpcd-**.*-armv71" (* represents the firmware version of the network card, which may not be the same for every Raspberry Pi version.), with "192.168.2.225 As the column, enter "192.168.2.225" in the browser to confirm to enter the operating system control terminal
3. Indicator light description
ACT is the channel indicator, which usually flashes only after successfully connecting to the network. PWR is the power indicator of the Raspberry Pi. The indicator is always on when the Raspberry Pi is powered on. What is the reason?), the orange non-Gigabit Ethernet indicator light and the green non-100M indicator light on the network card port on the back of the digital broadcast.
④Description of playback output DsD and DTs
Currently testing the Volumio and Moode systems, the DSD direct output can be played normally DTs, DsD16, DSD32, DsD64, DsD128, DSD256, DSD512 output, but the decoder support is required, I am AKM4495, AKM4497, AKM4499, ES9038Q2M can be normal Play output, if there is no sound output, please check the decoder yourself.
product description
1. The digital chip adopts Wolfson&x27;s high-end WM8804G chip and adopts I2S interface; it supports 16- to 24-bit audio data format; distortion and dynamics are very ideal; it supports a high sampling rate of 192kHz, and advanced anti-shake technology can inherently shake ( Intrinsic period jitter) is within 50ps RMS and the degree of reduction is extremely high.
2. The output port adopts optical fiber and coaxial two kinds of interface output, which is convenient for user external power amplifier
3, support hardware control volume (I2C interface)
4, the power supply using raspberry pie power, no external power supply; and use π-filter power design, effectively reduce the power supply interference
5, using I2S interface direct digital output, high degree of reduction, non-USB interface DAC mode, does not occupy the other extended GPIO Raspberry Pi
6, provide power indicator light, easy to observe the status of the expansion board
7. The PCB board adopts a gold-plated process on a tall, arc-shaped track (high-end HIFI DACs use arc-shaped tracks) to better ensure the continuity of signal impedance and reduce signal reflection and refraction.
8, good sound depends on real materials, fiber optic interface using imported HIFI-class high-quality fiber seat, coaxial interface is used Pluse company imported audio isolation transformer in the provision of good digital audio while protecting your audio equipment and board
9, integrated infrared receiver function, in the absence of a network, more convenient control of playback.
