Description
The HPA V222 is a newly developed balanced headphone amplifier in the Violectric range. As a true (!!) balanced amplifier it is equipped with four amplifier stages and not only balanced connectors!
The roots of the amplifier circuitry can be found in its praised and rewards winning predecessors V200, V220, V280 and V281. Inside HPA V222 it features the similar natural but smooth and pleasing sound. Because of its matchless technology HPA V222 not only offers a powerful headphone amplifier, but also:
LOWEST NOISE Through a very small amount of internal gain. This makes the amplifier's self-generated noise inaudible.
HIGH OUTPUT VOLTAGE Through 50 V internal operating voltage. Therefor ideally suited for high-impedance headphones deserving high output voltage swing.
HIGH OUTPUT POWER Thanks to powerful amplifiers that offer far more power even the most demanding headphones would need. So best suited for headphones with low impedances as well as magnetostatic headphones !!
HIGH DAMPING FACTOR Due to lowest output impedance. Therefor the ideal match for difficult to drive headphones without negative side effects and with the guarantee for a uncompromising frequency response.
2 stereo inputs, balanced via XLR, unbalanced via RCA
Inputs switchable on the front panel
+/- 18 dB Pre-Gain for a perfect match of the HPA V222 between source and headphones
