General - Violectric HPA V222 User Manual

GENERAL INFORMATION
VIOLECTRIC HPA V222 contains 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 both front mounted
balanced headphone sockets (4-pin XLR and 4.4 mm Pentaconn) it is
a real balanced amplifier and the balanced connectors are 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, HPA V222 fulfils even highest demands.
