Well-designed and solidly built, the Gustard H10 is a powerful, Class A, output stage headphone amplifier designed for home listening.

  • H10 is a high-current discrete Class A output stage headphone amplifiers, each channel consists of two independent amplification circuit, has RCA inputs, balanced input, you can easily connect a variety of sources
  • Machine using a buffer amplifier plus pre-amplification stage main components. Buffer preamp gain adjustment function with four segments, with the four pairs of audio power output circuit tubes on the CPI, you can easily drive a variety of different impedance headphones.
  • using two 25W seal ring cattle, independent power between left and right channels, effectively reducing the left and right channel crosstalk.
  • Adjust the volume potentiometer placed at the back of the input stage, effectively shortening the audio channel path, reducing interference,tri-band balanced sound correctly, the output resistance low current, suitable for most headphone mix.
  • start-up delay, DC offset, overload, protection circuitry to ensure the safe use of the machine,RCA single-ended and balanced XLR inputs, input switching and gain adjustment.
