NANOSOUND AMP^2

Following the success of NanoSound DAC, Nanomesher continues to develop our Raspberry Pi Audio range. Here we present NanoSound AMP^2 - A Very Efficient Headphone + Speaker Amp Add on for your NanoSound DAC. 

WHAT IS NANOSOUND AMP^2

The new amp add-on board for NanoSound DAC, NanoSound Amp^2 (Pronounced as "Amp Square"), include both a headphone amplifier as well as a very efficient 5W speaker amplifier.
It runs very cool due to its up to 90% efficiency allowing the whole unit (Raspberry Pi + NanoSound DAC + NanoSound MiniAmps) to be powered by one single microUSB cable (or  individually if you choose to). It's surprisingly loud and is enough to power a large room or a small lounge as demonstrated.
