Four Different Output Impedances Complement Tube Sound
AT-HA505H lets you choose from four different output impedances (two outputs each of 0.1, 33, 82, and 120 ohms) to experience a sound that best suits your headphones. Having tubes in the preamp stages adds warmth and depth to the music, while the bipolar transistors in the power amp stage provide distortion-free Class A amplification powerful enough to drive headphones of varying impedances without problem. Each part of the amplifier is fed by individual power supply units with fast recovery diodes and regulating circuitry.
Phenomenal Connectivity and Luxurious Features
Two analog inputs (L/R RCA line jacks and L/R balanced XLR jacks) and two digital inputs (S/PDIF digital coaxial input and USB input with selectable Asynchronous and Adaptive modes) are included. Additional features include classic analog VU meters with VU range selector switch, a large volume control knob, and an input attenuator switch.
