Violectric HPA V280 Balanced Headphone Amplifier

Violectric

The HPA V280 was developped with the target to enable ultimate transmission quality for low- , medium- and high-impedance headphones. These may also be balanced versions !!
Due to its specific, variable, low-noise and low-distortion circuit design especially optimised for dynamic headphones, the HPA V280 fulfils even highest demands.
Like his "bigger brother" HPA V281 also HPA V280 uses our famous V200 amp technology to enable the typical uncolored but smooth sound signature.

  • The four built-in amplifiers provide balanced operation of headphones !!

    Connection is made via 4-pin Neutrik XLR connectors.

    Two “standard” headphones may be connected via 1/4" jacks on the front panel.

    This amp may be equipped with one of six different digital inputs:

    Coaxial, Optical or USB with either 24/96 kHz or 24/192 kHz

    Case and back panel are made of aluminium and are Nextel coated.

    The 8 mm frontpanel is black or silver anodized. The labeling is laser engraved.
