HEADPHONE AMPLIFIER HPA V220

The HPA V220 was developed with the target to enable ultimate transmission quality for low- , medium- and high-impedance headphones. Due to its specific, variable, low-noise and low-distortion circuit design especially optimized for dynamic headphones, the HPA V220 fulfills even most sophisticated demands. Furthermore HPA V220 offers selectable inputs and an output management.

 

LOW-NOISE
because of low internal gain. Therefore the self generated noise from the amplifier is not audible.

HIGH OUTPUT VOLTAGE
through 60 Volt internal operating voltage. Therefore best suited for high impedance headphones. Over 90 % of all headphone amplifiers in the market offer not half that voltage !! 

HIGH OUTPUT POWER
because of powerful amplifiers able to deliver much more current a headphone needs. Therefore best suited for low impedance headphones and even magneto-static cans !!

HIGH DAMPING FACTOR
through lowest output impedance. Therefore best suited for full control even over critical headphones with the guarantee to have flattest possible response.

aluminum front panel

 

The inputs and outputs are situated on the rear panel, they are equipped with electronically balanced gold plated XLR connectors and unbalanced gold plated RCA connectors. This amp may be additionally equipped with one of six different digital inputs: Coaxial, optical or USB with either 24/96 kHz or 24/192 kHz Balanced and unbalanced line outputs on the rear panel. These can be set to have fixed output level (mirrored from the input) or variable output level from the volume control. Volume control is provided with a high-grade ALPS RK 27 pot with a large full metal rotary knob.

Additionally a balance control serves to correct the stereo image. The output management enables the amp to act as your personal preamp when desired. Feel free to activate the headphones outputs or the line outputs independently from each other with dedicated buttons on the front panel.

Lots of protection circuits will care for the safe operation of your headphones. Two headphones may be connected via 1/4" jacks on the front panel. Case and back panel are made of aluminum and are Nextel coated. The 8 mm aluminum front-panel is milled, sand blasted and anodized. The labeling is laser engraved.
