FX-Audio WR-02J When purchased new, it is usually sold as the main unit only, but we will also include a dedicated adapter (sold separately). This is a Bluetooth receiver product designed specifically for audio equipment, enabling Bluetooth connectivity by connecting to audio devices that do not support Bluetooth, and supporting high-quality/low-latency communication methods. For analog output, the "ES9028Q2M" DAC IC realizes high-quality output from the digitally received Bluetooth signal. The LED level meter on the front panel displays the audio input signal level in real-time, allowing you to enjoy it visually. With three versatile output terminals, it can be connected to multiple devices simultaneously, expanding Bluetooth wireless connectivity not only to a single device but also to multiple devices. You can connect multiple amplifiers that do not have a Bluetooth input function simultaneously, or connect it to built-in amplifier speakers to enjoy it as a Bluetooth speaker.
