K2Audio KLABXBG2 Gen 2 Bluetooth In Wall Amplifier Kit Including Power Supply
The KLABXBG2 is a compact powerful wall mount amplifier fits into a standard UK two gang pattress.
It is available in 3 versions:
KLABXBG2 - Bluetooth only (This model)
KLABXBG2F - Bluetooth plus front line (aux) input
KLABXBG2J - Bluetooth plus rear line (aux) input
It is designed for easy fuss-free operation with no switches or remote controls required. To use it simply connect via Bluetooth and control the volume with your bluetooth device. When you disconnect or stop streaming the amplifier automatically reverts to a very low power standby mode. Whenever you connect again it instantly wakes up to deliver clear powerful audio.
This amplifier features K2Audio-simple-audio-setup or KSAS for short. This allows custom elements such as Bluetooth ID, Gain and EQ to be modified without the need for a programming cable.
