GUSTARD H10 High-Current Discrete Class A HiFi Stereo Headphone Amplifier

Features:
1.AC115V/230V international voltage input.
2.Rigorous design, reasonable layout, elegant lines, solid materials.
3.Aluminum chassis, before grinding Shahoulasi processes, machines all black.
4.RCA single-ended and balanced XLR inputs, input switching and gain adjustment.
5.Start-up delay, DC offset, overload, protection circuitry to ensure the safe use of the machine.
6 tri-band balanced sound correctly, the output resistance low current, suitable for most headphone mix.
7.Adjust the volume potentiometer placed at the back of the input stage, effectively shortening the audio channel path, reducing 
interference.
8.Using two 25W seal ring cattle, independent power between left and right channels, effectively reducing the left and right 
channel crosstalk.
9.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.
10.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.
