For background music and announcements in commercial premises, the Adastra IWA460B installation amplifier is designed for wall or ceiling mounting. Class D technology and an internal switch-mode power supply reduce heat dissipation, while Bluetooth connectivity enables wireless audio streaming from a smartphone or another compatible device.

The integrated master control adjusts the volume, while the 3.5 mm Aux input and optical digital input allow audio sources to be connected. Speakers connect via Euroblock terminals, and the amplifier can be paired with different types of speakers for small or medium-sized spaces, or for wide-coverage installations.
