This compact Bluetooth audio amplifier allows the connection of Bluetooth devices to low impedance speakers via the built-in power amplifier. The unit can power up to 2 x 15W speakers at 4 or 8 Ohms and is supplied with a 1 x 4 way phoenix connector. The compact design makes the unit ideal for fitting into small spaces like ceiling voids and is powered by a 15V 2A PSU (Supplied). The unit is ideally suited to ceiling speakers but can work equally well with wall or floor mounting units. A key feature in Bluetooth 5.0 is that bluetooth 5.0 enabled devices such as smartphones (check the capability of your device) can transmit audio to two amplifiers within a 10m range at the same time .No password is required which means it is ideal for making connection to Smart home devices.
