Product Description

A digital audio amplifier with Bluetooth connects music sources wirelessly or via cable to active subwoofers or bass monitors. The device processes audio signals digitally and outputs them at up to 50 W into four-ohm loads, which is sufficient for room applications with subwoofers or active speakers.

The Bluetooth 5.0 connection transmits audio losslessly with the aptX codec, while the built-in inputs also connect to headphone outputs or RCA devices. The bass filter can be adjusted via a menu to adapt low frequencies to the room or the speaker characteristics. For quick transitions between portable and stationary devices, the dual connectivity eliminates the need to reconnect cables.

Applications include home theater setups with a separate subwoofer, portable sound systems for events, or music workstations that require precise near-field bass. The module also works as a preamplifier for multiple speakers in adjacent rooms, as several devices can use the same Bluetooth transmitter.

Power is supplied either via USB-C (for mobile operation with power banks of up to approximately 3 A) or via the included 12 V power adapter (for stationary installation). If you want to operate the amplifier permanently with a subwoofer, use the power adapter; for outdoor use or in vehicles with a 12 V electrical system, no additional power supply is required. Speakers with an impedance of less than 4 ohms overload the output beyond its thermal limit.

Safety Information

The power adapter supplies 12 V DC and is intended exclusively for operating this device. This product is not intended for installation in household electrical circuits and is intended solely for building prototypes and for testing and development purposes. Work on or near electrical installations must be carried out by qualified electricians; if you have questions about safe commissioning, consult a qualified electrician before making any connections.
