TPA3250 Hifi Bluetooth Amplifier Bluetooth 5.0 130W+130W Digital Power Amplifier Assembled For LDAC

TPA3250 Hifi Bluetooth Amplifier Bluetooth 5.0 130W+130W Digital Power Amplifier Assembled For LDAC

Description:
This product is designed for the most discerning and musicians. It integrates the current TPA3250 power module with very low distortion and Bluetooth decoder module QCC5125 that supports for LDAC and APTX, and integrates PCM5102A high-end decoder chip, so the low-frequency sound is thick and the voice is warm, high frequency penetration is excellent.

As an amp, it can be connected to 3.5 stereo headphones.

The harmonic distortion of the digital power amp is as low as 0.005%, which is beyond the recognition range of human ears!

TPA3250 is a high-performance class D power amplifier chip. It has Class D efficiency and can bring high-end sound quality. The device features advanced integrated feedback design and proprietary high-speed gate driver error correction function. This technology allows the device to maintain ultra-low distortion throughout audio frequency band while exhibiting perfect sound quality.

Features:
- Bluetooth 5.0 ultra-low harmonic distortion digital power amplifier
- Hifi HD high power output 130W+130W
- For aptx HD. It can support up to 24-bit/48kHz audio, which means that we can listen to music with better sound quality with wireless devices. Compared with 352kbps for aptX, its bitrate is increased to 576kbps
- Support for aptx adaptive, combining the advantages for aptx hd and Lossless, can adaptively adjust sound quality and delay. It creates wireless audio technology that can be used across devices, suitable for smartphones, tablets, headsets, gaming headsets and speakers. Provide you with the ultimate and excellent wireless listening experience
- For LDAC, it can stream 96KHz/24bit music (also known as high-resolution audio) via Bluetooth, with a speed up to 990kbps. For LDAC, it can transmit about 3 times the amount of information that ordinary Bluetooth audio [refers to using A2DP protocol, SBC encoding] (328Kbps, 44.1KHz)
- The independent decoder uses PCM5102 chip. Low frequency sound is full, full of flexibility, and the level of detail is very good. S/N ratio is 112db, distortion is -93db
- Mastering CD sound quality. For WAV, FLAC, MP3 and APE
- For APTX HD high-definition enthusiast decoding. Audio technology can ensure that devices supporting wireless bluetooth can provide high-definition HD audio. This technology can protect audio data during audio transmission and provide a listening experience "better than CD". Supporting for aptx-hd, you can enjoy immersive listening quality when using wireless devices
- Audiophile-grade op amp preamp, using 2pcs NE5532 operational amplifier, low distortion, high dynamics, and excellent vocals
- High-speed filter capacitor array
- Low loss, low heat, remove high current output fully shielded inductance and digital sound, human voice is very good
- The newly launched QCC5125 module is an upgraded version of CSR8675. In addition to supporting for LDAC APTX-HD protocol of CSR8675, it is also compatible with Bluetooth protocol for aptx adaptive, which is not available in CSR8675
