KLABXBJ Bluetooth Express Digital In-wall Stereo Amplifier with Line Input
Easily add music to your kitchen, bedroom, study, bathroom etc. This tiny wall mount amplifier fits into a standard UK two gang pattress and provides a powerful 20W RMS per channel. In operation it really couldn't be any easier. When you want to use it simply connect via Bluetooth and control the volume with your bluetooth device. When you disconnect or stop streaming the amplifier automatically switches into very low power standby mode. Whenever you connect again it instantly wakes up to deliver clear powerful audio.
There are no switches or remote controls, it really is a fit and forget solution. During installation you can choose from one of seven Bluetooth ID's to make sure you are always connecting to the correct amplifier. Its also easy to use with an Amazon Echo Dot.
This model also feature a rear line input via stereo 3.5mm jack socket. Auto signal sensing is employed, so if a signal is present on the rear line input this takes priority over the bluetooth. If the rear signal level becomes inactive for more than 20 seconds the amplifer automatically goes back to low power standby. It will instantly wake again whenever a signal appears on the line input or a bluetooth conenction is established.
