Hardware Open-Source HIFI Bluetooth + USB DAC Decoder (QCC5181 + PCM1794A)
Streaming DAC (with preamplifier)
Brand: Thomsonic
Model: TS200 Streaming DAC
Motherboard size: 280mm * 160mm * 1.6mm, black
RCA output: 2V Rms – 6V Rms (ASPL potentiometer)
Hardware configuration: QCC5181 + PCM1794A + 2.4-inch OLED + 2.9-inch E-ink screen (finished board)
Bluetooth supports LDAC, LDHC protocols, Qualcomm protocols AVRCP, A2DP, aptX, aptX HD, aptX LL. It supports up to 24bit/192kHz PCM DAC 2-channel (16bit, 24bit, 32bit: configurable via APP).
Supports USB input, 96Khz 24bit, and automatic Bluetooth channel switching.
The preamplifier operational amplifier is JRC5532 or NE5532, and can be manually replaced with a higher-end operational amplifier OPA2604AP.
2.9-inch E-ink screen with a resolution of 296 * 128.
2.4-inch OLED menu screen with a resolution of 128 * 64, supporting menu selection.
Equipped with a 32-bit MCU single-chip microcomputer controller, supporting JLINK SWD interface for debugging and programming.
Supports post-stage voltage detection, pre-stage voltage detection, real-time display of power amplifier heat dissipation temperature, and overheat protection.
Relay signal control, optional to turn on the relay when Bluetooth is connected or when there is audio output.
Two-color LED device indicator: green LED for Bluetooth connection, purple LED for USB connection.
Supports NEC protocol infrared remote control.
Hardware configuration:
Full range of copper-pin resistors, 10000uF filter capacitor, 15A rectifier bridge, high-precision linear regulated power supply design.
The DAC part uses high-precision imported filter capacitors, and the DAC supports automatic mute function when powered off.
The motherboard design separates power ground, digital ground, and DAC ground, with low noise.
The Bluetooth antenna supports an external SMA socket.
The output coupling capacitor can be selected from models Benic 3.3uf/Jantzen Cross CAP 3.3uF
