Auido Technica AT-HA21 Headphone amplifier

• High-rigidity aluminum alloy body and die-cast molding front panel, suppress unnecessary vibration,
  suppress distortion and unnecessary vibration generated by the body itself, and achieve high sound quality
• Use carefully selected audio-specific parts to achieve perfect high-sound
  quality. Capacitors and operational amplifiers that shoulder the burden of high-quality performance are all carefully selected audio-specific parts.
• Equipped with a low-noise, low-distortion headphone amplifier, showing clear sound
• Achieve low noise by FET input, and can fully reproduce the delicate part
• Transistor type amplifier output, play sound with ease
• Using a large-capacity AC transformer to achieve the abundant low-frequency performance of high-power demand headphones
• Analog direct output function, AV system construction and expansion are easy and convenient
• Equipped with Ø 6.3mm stereo standard socket and Ø 3.5mm stereo mini socket, two earphones can be used at the same time
