B1 Basic Version-2 QCC5125 Bluetooth Receiver Bluetooth DAC Assembled Two PCM1794A For LDAC APTX HD

Version Comparison:

Basic Version-1:
- Chip: One PCM1794A
- Bluetooth: 5.0 (CSR8675)
- Output: RCA + 3.5 headphone jack
- Input: Bluetooth + USB + Type C
- With external power supply (DC 12v, 5.5-2.1 interface)

Basic Version-2:
- Chip: Dual PCM1794A
- Bluetooth: 5.1 (QCC5125)
- Output: RCA + 3.5 headphone jack
- Input: Bluetooth + USB
- Built-in power supply (AC 220v input)

Standard Version:
- Chip: One ES9038Q2M
- Bluetooth: 5.1 (QCC5125)
- Output: RCA
- Input: Bluetooth
- With external power supply (DC 12v, 5.5-2.1 interface)

Features:
- Rich in details and full of dynamics. QCC5125 Bluetooth + PCM1794A decoding
- Usage scenario: Bluetooth connection of mobile phone with speakers. Allow speakers without Bluetooth function to play music wirelessly. Old-style power amplifiers can also get rid of wires, and wireless music resources are more abundant
- Wireless input: It uses QCC5125 Bluetooth 5.1 solution. Supports for LDAC, aptX-HD, AAC and other encoding formats. Supports 24bit 96kHz audio CD-level sound quality, super cost-effective
- Good sound quality, no delay, no lag. Reduce the secondary loss of sound quality compression, accurately reproduce full audio broadband, HIFI-level high-fidelity
- Signal pass-through: turn off the volume control, keep the maximum level output, reduce signal interference, and make the sound more realistic
- MCU software control: It adopts the single-chip micro-controller solution, and the soft control optimizes the performance of the decoding chip. Turn on and off via the panel switch. Automatic recognition of input signal, broken sound elimination technology
- Solve the broken sound generated when switching songs, fast forward or sample rate changes through software control
- Filtering operational amplifier: Using active LPF and I/V conversion design. Compared with other passive resistance-capacitance structures, it is more conducive to improving the system's response speed to audio, making signal distortion lower, and music dynamics more swift and powerful
- 3pcs dual op amps: reserve the IC seat, and replace with op amps in different music styles by simply plugging in and out, making it more playable
- Protection output: HF original relay is adopted, which delays the signal closing when power-on, and disconnects immediately when power-off
- Solve the impact: avoid the popping sound that appears when starting up and shutting down, thereby protecting your speaker and avoiding damage
- High-quality power supply: Built-in true dual-source positive and negative voltage conversion design. Compared with other capacitor voltage divider structures, it is more conducive to improving the symmetry of positive and negative voltages, making the Bluetooth signal for LDAC more stable and decoding smoother
- Secondary voltage stabilization: high-performance power supply purification circuit design reduces ripple interference caused by switching power supplies, and provides clean power for DAC and LPF

Parameters:
- Input interface: Bluetooth 5.1 (QCC5125)
- Output interface: RCA (output level 2Vrms)
- Bit depth & sampling rate: 16-24Bit, 44.1-96kHz
- Power consumption: 0.48W (standby <0.1W)
- Bluetooth specifications: for LDAC, aptX-HD, aptx, SBC, AAC (Note: users’ mobile phone should support for LDAC and APTX functions)

Package Included:
- 1 x Set of Bluetooth Receiver

Note:
- It is assembled.
