Audio-Technica Consumer AT-HA5050H Hybrid Headphone Amplifier

BH #AUATHA5050H • MFR #AT-HA5050H
Audio-Technica Consumer AT-HA5050H Hybrid Headphone Amplifier
Key Features
  • 2 x E88CC Vacuum Tubes in Preamp Stage
  • Toshiba Bipolar Power Transistors
  • Sifam VU Meters for Precise Metering
  • Custom-Made R-Core Transformer
The AT-HA5050H from Audio-Technica is a hybrid hi-res audio headphone amplifier – hybrid because 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.

Audio-Technica Consumer AT-HA5050H Overview

The AT-HA5050H from Audio-Technica is a hybrid hi-res audio headphone amplifier – hybrid because 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.

Two E88CC vacuum tubes are used in the preamp stage to achieve the warm, mellow sound you can only get from tubes
A pair of Toshiba bipolar power transistors provide strong, driving power and high-quality sound
Sifam VU meters provide precise metering with a classic feel that matches the warm, analog tone from the tubes
Custom-made R-Core transformer counters spikes and instability in the power line, providing consistent, high-resolution amplifier performance with distinctive hybrid sonic characteristics
Lundahl transformers, Nichicon electrolytic capacitors and WIMA polyester capacitors are used to provide the best sound quality possible
Eight headphone jacks with choice of four different output impedances (0.1, 33, 82 and 120 ohms x 2) give you control of the sonic presentation without the extra noise that might be introduced by an impedance selector switch
Two analog (unbalanced RCA and balanced XLR) and two digital (USB and SPDIF digital coaxial) inputs allow the amplifier to be used with a wide range of equipment
