Description

Designed to fill three vital roles in one compact form factor, the DHA V226 from Violectric is a versatile D/A converter with a high-quality preamplifier and an audiophile balanced, stereo headphone amplifier. With support for 16- to 600-ohm headphones, this unit can drive the most demanding headphones, such as planars and low-impedance dynamics, while the Cirrus CS43131 DAC chip provides 32-bit digital-to-analog conversion, with support for up to 384 kHz PCM sampling rates and DSD256 decoding.

The V226 sports efficient I/O including unbalanced RCA input and output, multiple headphone outs including 1/4", 4.4mm Pentaconn, and a true balanced XLR 4-pin out, as well as a USB-C digital input for DAC functions. With versatile, quality features like pre- and post-fader selection, pre-gain DIP switches, and a standard Alps RK 27 volume pot, it has never been simpler to control your signals.

Powerful Amplifier and Preamplifier
The V226 is designed to be operated as either a headphone amplifier or a loudspeaker preamplifier, with selectable inputs and outputs as well as pre or post gain routing. Protective circuits also help to avoid overloads.
  • Two unbalanced RCA stereo input pairs, one unbalanced RCA stereo output pair
  • Balanced XLR 4-pin stereo headphone output with wide ranging impedance support
  • Extra 1/4" and 4.4mm headphone outputs
  • Analog I/O selection 
  • Pre- or post-gain routing selection 
  • Rear panel DIP switches for pre-gain control up to ±18 dB
Versatile DAC
The V226 sports powerful DAC hardware via its Cirrus-based CS43131 DAC chip which supports 32-bit PCM decoding and an impressive 130 dB dynamic range. Through USB-C, sample rates as high as 384 kHz PCM and DSD256 can be achieved.

Professional Quality Electronics
The V226 is built to the highest standards with top-grade electronics. From high-quality resistors to reliable controls and connectors, this desktop unit is built to last for years of continuous use.
  • One toroidal transformer with large filter capacity of >200,000 uF
  • Alps RK 27 attenuator control made from solid, 38mm aluminum
  • Four powerful amps offering 3500mW Pmax into 100 ohms and 23V RMS into 600 ohms
  • Delayed coupling of headphones to amp after power activation
  • Headphone path and line-out path individually switchable
  • Rugged black anodized aluminum chassis
