ProCaster BT-04 is a versatile Bluetooth 5.0 audio receiver and digital-to-analog converter (DAC) that allows you to turn your regular speakers into wireless Bluetooth speakers. The device features Bluetooth, optical (Toslink), and coaxial inputs, supporting high-resolution audio (24-bit / 192 kHz). Outputs include RCA (L/R) and 3.5 mm AUX, making it compatible with most stereo systems and active speakers. After the initial pairing, the connection is established automatically. Includes a remote control for remote operation. Powered via the included USB cable (power adapter not included).

The 3.5 mm output is suitable for line-level signals, such as active speakers or amplifiers. The device does not include a separate headphone amplifier, so it is not suitable for direct use with high-impedance headphones.
