BT5.1 Bluetooth DAC Decoder Board Bluetooth Receiver Board with QCC5125 ES9018K2M for APTX HD LDAC

BT5.1 Bluetooth DAC Decoder Board Bluetooth Receiver Board with QCC5125 ES9018K2M for APTX HD LDAC

Features:
- Configuration: QCC5125 Bluetooth chip and ES9018K2M DAC chip. Lossless for APTX HD and LDAC.
- Its output is designed with a high-end independent decoding chip from the United States, making its sound quality reach the CD level. In terms of level, dynamics, detail, high frequency and low frequency extension, it is better than the average toy level Bluetooth board.
- Its High-frequency sound without burr, the midrange is rounded, and the low-frequency sound is powerful and has good elasticity
- PCB size: 35 x 65mm/1.4 x 2.6"
- One AUX input makes it easy to connect other wired sources to switch. The board adopts the Bluetooth priority principle, that is, when there is no Bluetooth connection, it will automatically work in the AUX state, which is very convenient to use. The switch between AUX and Bluetooth is carried out by using Japanese original high-precision relays to ensure lossless signal docking.
- Its op amp circuit is powered by ±13.5V power supply. Equipped with an op amp base for easy replacement of op amps later to get your favorite sound.
- Higher than the CD bitrate standard
- Encoding formats supported by Bluetooth 5.1: protocol for LDAC, Aptx HD, Aptx Adaptive, Aptx, AAC, SBC, etc.
- Built-in ESS9018K2M decoding chip: It is an independent high-quality decoding chip. The powerful detail restoration capacity of its chip ensures a lossless effect. It uses external independent positive and negative high-voltage I/V circuits, while ordinary decoding chips use internal single 3.3V low-circuit I/V circuits.
- Bluetooth 5.1 QCC5125 chip makes the transmission speed faster and the performance more stable. The internal design has been updated and the Bluetooth connection is stable, allowing you to enjoy the sound quality better.
- Bluetooth transmission distance is over 10m/32.8ft. Support for APTX HD and LDAC HD transmission protocol.
- Supports for aptX HD 48khz and LDAC 96kHz HD audio transmission.
- Its Bluetooth Hifi sound quality is as good as the one by wired connection. It supports high-specification audio protocols such as for LDAC, APTX-ADAPTIVE, APTX HD, APTX and AAC. Its maximum transmission bitrate is 990KBPS. Support 96KHZ/32bit sample rate.
- With ultra-low latency technology, the gaming experience and video experience are significantly improved. For gaming and multimedia applications, the technology for APTX-LL is critical to synchronize audio and video. It allows you to listen to streaming from your favorite media services and ensures consistent music quality.
