Description

Violectric DHA V590: reference quality DA converter, 32 bit resampler and headphone amplifier

Violectric presents the DHA V590, a powerful combination of DA converter, resampler/reclocker, preamplifier and headphone amp. It offers digital inputs in XLR, Cinch, optical or USB. The digital signal is then processed by the 32 bit resampling/reclocking unit before being translated to the analogue domain by AKM 4490 converters, accepting up to 384 kHz and DoP. High-quality Alps pots control level and balance for up to two unbalanced and one balanced set of headphones. The Pre Gain circuit allows for adjusting levels to match the headphones model of choice. With its high-quality metal front plate, excellent components, great connectivity and a remote control, the Violectric DHA V590 becomes the centre of a home audio system.

The full package for audiophiles – converter and headphone amp

The Violectric DHA V590 integrates a complete listening system consisting of audiophile converters with resampling/reclocking, superb preamplifier and powerful headphone amp. Each section in itself is reference quality, creating a listening experience of exceptional sonic depth in their combination. A myriad of connections and additional switching options qualifies the DHA V590 as the control centre of the home audio chain – with remote control for optimal integration.

Top-quality signal conditioning and conversion

The Violectric DHA V590 employs two 32 bit AKM 4490 DACs in dual-mono configuration to translate digital audio data into analogue sound, transporting digital audio from various sources with up to 384 kHz and DSD-over-PCM (DoP) into the analogue domain with outstanding quality. To get the most out of the converters, the V590 offers signal conditioning. The 32 bit resampler/reclocker receives its working frequency from a femto clock, has a dynamic range of 180 dB and practically eliminates potential jitter entirely. This enables a particularly clear resolution free from artefacts.

First-class amplification for headphones and more

The freshly converted premium audio signal is forwarded to multiple headphone outputs of the Violectric DHA V590: one balanced and two unbalanced headphone connectors stand ready on the black anodized front plate. For optimal reproduction, a Pre Gain can be set on the back of the device, adjusting the levels to the headphones type used. The front also holds a large volume pot and a balance pot to tailor the levels of left and right channel to individual requirements.

Versatility through connectivity

A host of connection options enhance the versatility of the Violectric DHA V590. Three analogue sources can be connected through one balanced XLR and two unbalanced RCA inputs. For digital signals the device offers XLR, coaxial, optical inputs and USB for PCM and DSD. Regarding outputs, the V590 has another trick up its sleeve: in addition to the three headphones outputs on the front, it also provides balanced XLR and unbalanced RCA outputs at the back, so it can be used as a preamplifier for loudspeaker playback. Headphones and line outputs can be used individually or simultaneously. As the control centre of an audio system, all inputs and outputs can be switched on the device front or via the remote control.

High-quality components and manufacturing

In line with the Violectric commitment to quality, only the best components are used for the DHA V590. The audio signal is brilliantly translated to the analogue world by the AKM 4490 converters and set to the right level with a motorized Alps RK 27 potentiometer and a symmetrical amplifier circuit with 16 transistors per channel. Another Alps RK 27 is used for the balance pot. Additional circuits protect the device from DC, overload and overvoltage and connected headphones by delaying initial onset when powering on the amplifier. All this electronic finesse is housed in a solid, black anodized enclosure with an eight millimetre front plate. The DHA V590 can also be equipped with a relay-based volume control with 256 steps upon request.

Lake People - and by association Violectric - put high emphasis on domestic manufacturing. As well, all component suppliers are chosen in order achieve the main part of added value inland.


Introduction to Lake People

Established in 1986, we have since become your partner for professional audio electronics. Following our motto “tools - not toys”, we achieved highest reputation during the past years amongst our customers. These are private studios, broadcasters and TV companies. Also airports, congress and exhibition centres count on the reliability of our products made in Germany. This all began under the roof of Rosgartenstrasse 13 in the city of Konstanz. Here, three young guys started with the development and manufacture of limiters and noise gates but not too successfully in the beginning. The commercial survival on a very low level was made possible by the production of headphone amplifiers. From 1989 on, the production range was extended to level matching and balancing amplifiers such successfully, that it came essential to move to larger premises.

Since 1991, the new address read: Haidelmoosweg 52. Due to the developement of the first german 20-bit A/D and D/A converters in the beginning nineties, the name Lake People resounded throughout the land. Suddenly, the company was regarded as a high-tech brand, with a highly positive effect on its public reputation. The growing know-how led to many new products in the analog and digital domain during the following years. Although some projects turned out to be flops, most devices met the customers' requirements, with the effect of continuous growth of the company. By the end of the nineties the 140 m² of Haidelmoosweg 52 went cramping.
Again, a move to new premises came necessary. As it was obvious that rental facilities would not meet the demands, we decided to put up our own building. The company site was constructed in 2000 in a new industrial park in Konstanz, Turmstrasse 7a, just a hundred metres from the lake. Also in 2000, Lake People was transformed into a Ltd. company.
