The AT-HA5050H is a hybrid hi-res audio headphone amplifier. It employs a pair of tubes at the preamp stage and transistors at the power amplifier stage. It can be used when paired with headphones to bring warmth and depth to music and is powerful enough to drive eight headphones of varying impedances without any problem for home or studio applications.
The headphone amplifier is equipped with two analog inputs (L/R RCA line jacks and L/R balanced XLR jacks) and has two digital inputs (S/PDIF digital coaxial input and USB with selectable Asynchronous and Adaptive modes). The DAC is optimized to be compatible with digital audio formats up to PCM 32-bit/384 kHz and DSD128.
Additional features include classic analog VU meters with VU range selector switch, a large volume control knob, and an input attenuator switch. The AT-HA5050H lets you choose from four different output impedances (two outputs each of 0.1, 33, 82 and 120 Ohms) to experience the sound that best suits you and your headphones.
