Power Dynamics Powerline A100B Black In-Wall Bluetooth Amplifier 4 x 20W

The Power Dynamics Powerline A100B is a compact in-wall stereo amplifier designed to power up to four speakers. Its built-in Class-D digital amplifier delivers 4 x 20W and supports speakers with an impedance of 4–8 ohms, making it suitable for discreet ceiling-speaker installations in living rooms, verandas, garages, showrooms, cafés and restaurants.

A gloss black, touch-sensitive control panel provides access to source selection, standby, volume, track navigation, play and pause functions. Once installed, its connections and cabling remain concealed within the wall for a neat, low-profile finish. A remote control is also supplied for convenient operation.

Bluetooth 5.0 enables wireless audio playback from compatible mobile phones and other Bluetooth devices. Music can also be played from a USB flash drive or microSD card, with each storage option supporting capacities up to 32GB. Using both inputs provides up to 64GB of combined storage, with playback support for MP3, WAV, APE and other audio formats. A 3.5mm auxiliary input accommodates external audio sources, while line input and output connections provide additional system flexibility.

The package includes the amplifier control panel, a back box, two fixing screws and a remote control. An A100W version is offered with a white finish.
