The A 20 Headphone Amplifier from Beyerdynamic is designed to drive up to 2 pairs of headphones whose impedance ranges between 30 and 600 O transparently, without coloring your source signal.


The amplifier has a discrete design and features gold-plated stereo RCA inputs. In addition to the dual front-panel 1/4" headphone outputs, the A 20 has a pair of stereo RCA outputs that are looped through from its inputs, allowing your signal to pass through without loss, even when the amplifier is powered off. The dual 1/4" headphone outputs are connected in parallel, and are both controlled by the front-panel volume knob.
