AirDance Black BT-450 Bluetooth5.2 CD Player Lossless OPA2604 HiFi Op Amp Stereo CD Player DTS Decoding

Features:
- Built-in CSR lossless Bluetooth5.2 audio receiving function, with short latency and faster transmission speed. Open your phone and enjoy lossless online music.
- USB supports 16 bit lossless formats such as APE, WAV, FLAC, etc; It also supports MP3 and WMA regular audio. The lossless format is 10 times that of MP3 format, and the sound quality is comparable to CD discs. Massive lossless music resources online, allowing you to enjoy high-quality music without the need for a disc.
- Supports for DTS/DTSES/DTSHD and other multi-channel CD discs, supports analog 2.0 or digital 5.1 output, coaxial fiber and true multi-channel amplifier connection, can achieve multi-channel surround sound effect. Simulation 2.0 is suitable for connecting to HiFi amplifiers.
- The audio decoding DAC chip adopts the Taiwan produced SD7402DTS 24bit/192KHz, D/A digital analog audio processing. The operational amplifier uses OPA2604AP dual operational amplifier, which has excellent output driving capability and a relatively high small signal and power band. The sound is warm and the fidelity of the restoration is high.

Components Details:
- Movement: For Sanyo EP850 high-precision movement has a stable and long lifespan, and can pick up audio signals more accurately. The CD drive can only play CDs and does not support other types of discs.
- Operational amplifier: Using for BB OPA2604AP (ceramic sealed) operational amplifier. This operational amplifier is characterized by extremely low harmonic distortion, low noise, and high gain bandwidth. The plug-in operational amplifier socket is suitable for audiophiles to freely upgrade to higher end operational amplifiers.
- Switching power supply: The main features of a switching power supply board are high efficiency, small size, light weight, stable output, multiple protection functions, and a wide input voltage range. The voltage range of 110-240V is suitable for domestic and foreign users.
- For JHX crystal oscillator clock: The JHX27.000 crystal oscillator clock can generate highly stable oscillation frequencies, which are used as clock signals to ensure that various components inside the CD player can operate in the correct time sequence. Through the clock signal provided by the crystal oscillator, various parts of the CD player can maintain synchronization, ensuring accurate reading and playback of audio signals.
- Digital Audio Processor: The audio processor adopts for PT2314E, which effectively integrates volume, bass, treble, left and right channel balance, and loudness functions into an electronic audio processor, enhancing low-frequency or high-frequency response. Low power consumption and high signal-to-noise ratio, reduce background noise, and output purer audio signals.

Functions:
- For Sanyo EP850 movement is widely compatible, durable, and has strong error correction.
- Supports stereo CD/HDCD/HQCD/LPCD/K2CD/DTS CD/XRCD/vinyl CD and other audio discs.
- USB supports 16 bit lossless APE/WAV/FLAC and MP3 audio.
- CSR Bluetooth5.2 wireless receiving makes listening to music on mobile phones more convenient.
- Supports for DTS 2.0, DTS 5.1/6.1 channel decoding.
- RCA left and right output, fiber optic and coaxial digital audio output.
- Power off memory playback function.
- Single loop/full disc loop/A-B loop.
- Built-in DSP chip with 8 sound effects to choose from, choose the appropriate listening style for yourself.
- 7-point array digital display screen.
- The CD player needs to be connected to an amplifier, active speaker, and Bluetooth speaker for use.
