Instructions:
Bluetooth passwords: 0123
QCC5125 version: Bluetooth 5.1, support APTX and APTX-HD and LDAC, support Android and Apple mobile phones, the highest transmission reaches 96K 24BIT.
QCC3034 version: Bluetooth 5.0, support APTX and APTX-HD, support Android and Apple mobile phones, the highest transmission is up to 48K 24BIT.
Features:
This product is specially designed to add high-quality Bluetooth function to various non-Bluetooth power amplifiers. It is very simple to use. The board adopts the same level of Qualcomm's new QCC5125 solution and supports 24BIT APTX HD lossless protocol. Note that APTX HD is one grade higher than the general APTX. True Bluetooth 5.1, the output is not a simple output. The output uses ES high-end decoding solution ES9023, which is much better than the general S9018K2M, full of voice, low frequency and dynamics, and the level of detail is much better than the direct output of many mobile phones
ES9023 uses the industry's advanced SABRE digital-to-analog conversion technology. This chip combines good sound quality and high cost performance, making it an ideal choice for digital-to-analog conversion. It can be applied to products such as Blu-ray players, CD/DVD, high-definition set-top boxes, digital TVs or audio receiving devices.
ES9023 uses patented Hyperstream architecture and time-domain jitter elimination technology to achieve jitter-free recording level sound quality, with a dynamic range of 112dB.
PCB size: 5X3.5CM, pin distance 2.5MMX6
Why Add Anolog Input?
Because the signal source of the user is not Bluetooth, it is very troublesome to switch, pull back and forth, all this analog input is very useful, after the mobile phone Bluetooth pairing, turn on the Bluetooth signal, the mobile phone Bluetooth signal is disconnected, and turn on the RCA input of the original amplifier aisle.
If you don’t want analog input, just leave those 2 pins idle.
The board has 2 power supply mode options:
