FiiO BTR5 Portable Bluetooth Amplifier

In the BTR5, after the Bluetooth signal is processed the FPGA greatly reduces jitter and improves signal stability, completely solving the problem of different clock rates that exist between the different parts of the audio architecture. Included is the Qualcomm CSR8675 – a low-power Bluetooth chip with enhanced audio capabilities, allowing it to powerfully handle various Bluetooth decoding functions with ease.

With the addition of a dedicated FPGA, the 45.1584/49.152 MHz dual crystal oscillators during Bluetooth and USB decoding can more accurately reproduce audio signals under various sampling rates, giving the BTR5 exceptional audio fidelity among Bluetooth amplifiers. With its precise clock management system and being set to synchronous mode, we fully unleash the potential of the ESS SABRE ES9218P for extremely detailed reproduction of sound. The multi-level analog gain and digital volume are combined into a singular dual-volume adjustment design, allowing you to adjust the volume more precisely while fully preserving the dynamic range in your music. In its truly balanced audio architecture, each channel is driven separately from the other with its own DAC and amplifier, allowing the BTR5 to bring you a purer sound with unmatched finesse and balance.

When you connect the BTR5 to your phone, the phone’s volume and the BTR5’s volume can be adjusted separately, allowing you to better fine-tune the volume to your needs. The BTR5 also remembers your desired volume, so you don’t have to adjust the volume to where you want it every time you use the device. When paired to a phone, simply double-click the multi-function button to wake up your voice assistant.
