Built as a 3-in-1 studio workhorse, theDHA V590fromViolectricis a versatile D/A converter with resampling and reclocking functions, a high-quality preamplifier, and an audiophile balanced stereo headphone amplifier all at once. With support for 4- to 600-ohm headphones, this unit can drive the most demanding headphones such as planars and low-impedance dynamics, while the ESS ES9026 Pro DAC chip provides dual-mono, 32-bit floating point delta sigma, digital-to-analog conversion, with support for up to 384 kHz PCM sampling rates and DSD512 decoding.
The V590 sports a plethora of I/O including balanced XLR input and output, unbalanced RCA input and output, multiple headphone outs including 1/4″, 3.5mm, and a true balanced XLR 4-pin out, and four digital inputs: XLR 3-pin AES, RCA coaxial, TOSLINK optical, and USB-B, which provides the highest available sampling rate. With versatile functions like pre- and post-fader selection, five modes of resampling with a femto-scale atomic sync clock, pre-gain DIP switches, and a standard Alps RK 27 volume pot, it has never been simpler to control your signals. The unit also comes with a convenient infrared remote control.
Powerful Amplifier and PreamplifierWith three analog input paths and five output paths, you have plenty of options for your analog signal routing. The V590 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.
Versatile DACThe V590 sports powerful DAC hardware via its ESS-based ES9026 Pro DAC chip, which supports 32-bit resampling and reclocking, with a huge 180 dB dynamic range. The DAC can accept any signal down to 16-bit and expand it to 32-bit for higher quality audio and avoidance of clipping. The internal atomic clock is accurate down to 80 femtoseconds, utterly eliminating any jitter in the resampling process. All digital signals can be expanded to 32-bit, and through USB, sample rates as high as 384 kHz PCM and DSD512 can be achieved.
Professional Quality ElectronicsThe V590 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 studio use.
