Distortion -107dB | S/N Ratio 122dB | Output power balanced 78mW | Output power SE 25mW Qualcomm CSR8675 Flagship-level Bluetooth abilities The Qualcomm CSR8675 Bluetooth chip used in the BTR3K is a premium low-power solution designed for enhanced audio applications, with a 120 MHz DSP, support for 24-bit transmission and processing as well as abilities to decode multiple lossless Bluetooth codecs. Support for the AAC/SBC/aptX/aptX LL/aptX HD/LDAC audio formats ensures that you’ll get the best sound quality possible from the BTR3K. Independent dual crystal oscillators for accurate audio reproduction The dual crystal oscillator system in the BTR5 also comes to the BTR3K! The 22.5792M/24.576 MHz dual crystal oscillators mean that during Bluetooth and USB decoding, the BTR3K can more accurately reproduce audio signals under various sampling rates – due to greatly reduced jitter and greatly increased audio stability. Intelligently puts your music at your fingertips When your device is connected to the BTR3K and is using the FiiO Music app to play music, the BTR3K can be remotely controlled with the following functions: 1、Channel balance 2、Switch between 4 kinds of audio filters 3、10-band professional EQ (equalizer)*EQ invalid in LDAC codec Note that the first time you turn on th power or clear the pairing information, the BTR3K will automatically enter the pairing mode. What the mobile phone can adjust is the the volume of the Bluetooth codec. If its volume is too small, the dynamic effect would be affected. While the BTR3K controls the volume of decoding and amplification which can decrease the loss of the sound quality. But the headsets with OMTP protocol only support normal listening. Microphone recording Android-based cellphones can normally use WeChat,Wechat calls, QQ voice and QQ calls. It depends on different systems of mobile phones. iOS system only supports WeChat voice, calls and QQ calls with the microphone of BTR3K. If taking a video, the phone mircophone is used. 4.EQ is invalid under BTR3K's LDAC. Is it a hardware defect or a software problem? Notices: Third-party music apps could also use the EQ adjustment if it is the function of BTR3K. If it indicates that the EQ is invalid, you can turn on the EQ switch and reboot the BTR3K to activate the EQ function. For greater power independent Dual AK4377A DAC and detail resolution,the BTR3K features both balanced 2.5mm and single-ended 3.5mm outpts. Can be remotely controlled via FiiO Music app to switch channel balance,8 different DAC lowpass filter and 10-band EQ
