The A1 headphone amplifier operates headphones with nominal impedance from 30 to 600 ohms. It provides excellent audio quality with high volume and strong bass response. The special circuit design features an amazingly natural sound reproduction with an excellent resolution and spatiality, transmitting at 96 kHz for transmission of the whole frequency response of a SA-CD or DVD audio. A microprocessor-controlled relay lets you silently select two high-class stereo sound sources. Volume control is made of solid aluminum with a high-grade ALPS potentiometer inside. The gold-plated RCA connectors on the back allow signal transmission from audio sources without loss. A large-dimensioned toroidal core transformer ensures high fidelity of impulse and dynamics. The combination of selected high-grade components allows even the highest-impedance headphones to be driven flawlessly over the entire frequency range. High impedance at the headphones output ensures the control range of the volume potentiometer to be perfect for low-impedance headphones, too. One input is passively connected with the lineout of the A1 to loop through incoming signals even when the A1 is in stand-by mode. Two blue LEDs on the front display the active signal input, another multicolor LED shows the operating status (stand-by or active). Stereo headphone amplifier is made in Germany. Includes toroidal power transformer, 1 line output, 2 audio inputs (gold-plated RCA), 32 ohm to 600 ohm headphones, T.H.D. 0.001% at 170 mW / 250 ohm, for use with all dynamic headphones.
