Industry Leading Performance With Ultra-Low Distortion Precision Linear Feedback Circuit:- S.M.S.L HO200 headphone amplifier features a fully balanced design with four ultra-low distortion precision linear feedback circuits (PLFC). It provides industry-leading performance with a distortion rating of just 0.00006%, and the A-weighted distortion rating is as low as 0.00005%(-126dB). Enjoy a high-class performance with your favorite headsets with the S.M.S.L HO200. Clean, Noise-Free Background With Low-Noise Power System:- S.M.S.L has adopted an ultra-low noise power supply system for the HO200 headphone amplifier. It has an ultra-low output noise rating of just 1.0uV. The Signal to Noise Ratio in the output is 140dB ensuring a super clean background in the output signal. Classically Retro Design:- S.M.S.L HO200 has a CNC precision-milled aluminum alloy shell. It has retro-style toggle switches for on/off, gain control, and output/input selection. It has a potentiometer volume wheel to precisely control the output volume. Balanced+Unbalanced Connections:- S.M.S.L HO200 has both balanced as well as single-ended connection options. It provides RCA+XLR input+pre-out options. For headphone output, it has 4-pin XLR and 4.4mm balanced outputs, and 6.35mm single-ended headphone output.
