Violectric HPA V222 Balanced Headphone Amplifier

The Violectric HPA V222 is a new balanced headphone amplifier in the Violectric range. As a true balanced amplifier, it offers four output stages and not just balanced connection options. The headphone amplifier is a further development of the multiple test winner HPA V200 and HPA V280 and offers the incomparable natural and pleasant sound that made its predecessors famous.

With its special technology, the HPA V222 not only offers one of the most powerful headphone amplifiers on the market, 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.

The rear line inputs can be selected via switches on the front. After the RK 27 volume control, the activated and buffered signal reaches the power amplifiers, which are a further development of the famous V200 circuits. Connect your headphones to the HPA V222 and enjoy a compact and fantastic sounding headphone amplifier with the famous natural, smooth but precise Violectric sound.
