The new Violectric HPA V550 and V550 PRO are high-end analog headphone amplifiers with a perfect preamplifier and a wide range of functions. These headphone amplifiers offer outstanding technical values, excellent sound and workmanship in the best manufacturing quality. The pre-gain circuit allows the amplifier to be adapted to the requirements of the headphones being used. Even critical designs such as magnetostats can be easily operated via the balanced and the two unbalanced headphone connections. Up to three analog stereo sources can be connected via one XLR and two RCA connections. The HPA V550 and V550 PRO also offers one balanced and one unbalanced output. High-quality ALPS RK27 potentiometers are used for volume and balance control.
