Beskrivelse

DHA V380 

The DHA V380 is a new top device in the Violectric range. It offers a state-of-the-art D/A  converter and a headphone amplifier. The D/A converter is a new development and includes  a 32-bit resampler / reclocker and two 32-bit D/A converters per channel. The latest findings from the multiple test winners from Lake People, Violectric and Niimbus were implemented in the headphone amplifier. 

DHA V380 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. Therefore 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. Therefore the ideal match for difficult to drive headphones without negative side effects and with the guarantee for a uncompromising frequency response. 


The DHA V380 offers: 

  • 2 analogue stereo inputs, unbalanced via RCA 
  • 3 digital inputs, opto and coax with 24 bit and 96/192 kHz capability,
  • USB with up to 32 bit and up to 384 kHz for PCM signals, DSD 64 – 512
  • 32 bit Resampling / Reclocking with 180 dB dynamic range, modes: On / Off / Best – 2 x 32 bit D/A converters per channel with -112 dB THD+N and 123 dB dynamic range – +/- 18 dB Pre-Gain for a perfect match of the DHA V380 between source and headphones – 4 powerful amps offering 5000 mW Pmax into 50 Ohm and 21 V RMS into 600 Ohm – Headphone path and line-out path individually switchable
  • 2 Single ended headphone outputs with 6,3 mm jack, 1 balanced output with 4-pin XLR – Line-out, stereo, 1 x unbalanced via RCA, 1 x balanced via XLR
  • 1 toroidal transformer, > 26.500 uF filter capacity
