Power Dynamics Powerline A50B In-Wall Amplifier and 2 Ceiling Speaker Set

The Power Dynamics Powerline A50B is an in-wall audio system combining a 2 × 20W Class-D digital amplifier, integrated music player and two low-profile 6.5-inch ceiling speakers. Its glossy black touch-sensitive control panel provides a clean, minimalist finish, while concealed installation keeps cables and connections out of sight.

Bluetooth 5.0 enables wireless audio streaming from compatible mobile phones and other Bluetooth devices. Music can also be played through the USB port or microSD card slot, with each supporting storage capacities up to 32GB. Supported playback options include MP3, WAV and APE audio formats, while the 3.5mm auxiliary input accommodates external sound sources.

The touch-sensitive panel provides standby, source selection, track navigation, play, pause and volume controls. A supplied remote control allows the system to be operated from a distance, and a blue backlight displays the selected settings.

The set includes two 2-way ceiling speakers with magnetic, flush-fitting white grilles and built-in crossover filters. Also supplied are a back box, remote control and 20 metres of speaker cable, comprising two 10-metre lengths. The system is suited to living rooms, verandas, garages, showrooms and restaurants.
