HPA V220

HEADPHONE AMPLIFIER HPA V220

Versions:
Front silver or black
Feet silver or black or gold

Volume control manual or
- remote controlled with motor potentiometer or
- remote controlled with 128-step relay attenuator

The HPA V220 was developped 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 optimised for dynamic headphones,
the HPA V220 fulfils 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 amplifer 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 magnetostatic cans !!

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


Features:

-  Balanced inputs with gold-plated Neutrik XLR connectors
Unbalanced inputs with gold-plated RCA connectors
-  Balanced line
outputs with gold plated XLR connectors
-  Unbalanced line outputs with gold plated RCA connectors
-  Line outputs assignable to be with fixed or variable level
-  6 optional digital audio inputs 24 Bit / 96 or 192 kHz 
-  3 switchable inputs with dedicated buttons on the front
PRE-GAIN = switchable input gain in five steps
Independent channel design
ALPS RK27 High-Grade volume control
-  ALPS RK27 High Grade balance control
High-Quality op-amps in the signal path
High-quality MKP capacitors in the signal path
0.1 and 1% metal film resistors throughout the unit
Discrete-design power amp with 8 transistors per channel
-  2 silver-plated Neutrik headphone outputs
-  R
elay-based headphone output cut- off with delayed switch-on
-  output management with dedicated buttons on the front:
    line outputs active, headphone outputs active, both active, both off (Mute)
-  Large t
oroidal transformer (15 W)
Large filtering capacitors in the power supply (18.000 uF)
Switchable ground lift
Rugged aluminium case with Nextel coating
Solid, laser-engraved aluminium 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.
V220 incorporates the award winning famous 8-transistor (per channel) amps from V200 for a smooth and relaxed sound stage.
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 aluminium and are Nextel coated.

The 8 mm aluminum frontpanel is milled, sand blasted and anodized.
The labeling is laser engraved.
