Violectric DHA V590² Pro Headphone Amplifier, Preamp, and DAC - Manual (Page 10)

10
GENERAL INFORMATION
VIOLECTRIC DHA V590 contains an excellent D/A Converter with a Resampling/Reclocking
function, a first-class Preamplifier and a high-grade stereo balanced Headphone Amplifier designed
to drive low-, medium- and high-Z loads (16...600 ohms) as usually represented by high-quality
headphones.
Because of its four built-in amplifiers and the front mounted 4-pin XLR socket it is a real balanced
amplifier and the four-pin socket is not only a convenience feature.
Due to its specific, highly variable, low-noise and low distortion circuit design especially optimised
for dynamic and orthodynamic headphones, DHA V590 fulfils even highest demands.
