Bluetooth 5.0 DAC Board Bluetooth DAC Receiver QS334 (Built-in Antenna) QCC3034 Outperforms CSR8676
Comparison of Bluetooth Versions:
- Format for APTX-LL resolves latency issues
- Industry's top Bluetooth coding technology for LDAC enables lossless transmission
Encoded Transmission Bandwidth (for reference):
Advantage:
The board adds an independent decoding chip PCM5102A to the output end, so that the sound quality reaches CD level. Compared with other bluetooth boards, it is much better in level, detail, high frequency and low frequency extension
Features:
- Built-in Antenna: When unobstructed, the transmission distance of the onboard antenna is 5-10m/16.4-32.8ft. Metal shell cannot be used with the decoder board featuring built-in antenna, otherwise the signal will be shielded.
- Bluetooth 5.0 for mobile phones, desktop PC, and tablet PC; for Windows, Android, and iOS
- The decoding part adopts PCM5102A. It is a 24bit stereo audio DAC chip with a dynamic range of 112dB and a distortion of -93db. Its high-frequency sound has no burrs, the mid-range is mellow, the low-frequency sound is powerful, and the elasticity is good
- The product has an AUX input, which is convenient for switching other external wired audio sources. Bluetooth priority; when there is no Bluetooth audio, it will automatically switch to AUX state, which is very convenient to use. Japanese high-precision relays are used for switching between AUX and Bluetooth to ensure that the signal is connected without damage
- Audiophile-grade components: capacitor for Philips BC, green audio filter, and solid capacitor for Fujitsu, providing purer power supply for HIFI sound quality
Specifications:
- PCB size: 37 x 65mm/1.5 x 2.6"
- Power supply voltage: 2P socket: DC5-32V; USB: DC5V
Attention:
It is recommended to use an independent power supply for the Bluetooth board, because when the board and a power amplifier share the power supply or are used in a car, there will be possible to generate noises. Users can install an isolated power module to solve the noise.
Package Included:
- 1 x DAC Board
