This is an assembled buffer board using diamond buffer architecture. Diamond buffer is well-proven structure in audio application with the strength of wide bandwidth and strong driving capability.
The buffer board can be used as a building block in the audio path, such as a buffer in between the digital audio source and the preamplifier, or even as a preamplifier( gain of 1) by adding a potentiometer at the front.
PCB dimension: 60mm x 43mm.
The board requires a +/-15V DC power supply. Current consumption would be decided by the loading.
