Description

The Violectric DHA V226 is a newly product in the Violectric range. It offers a competitive D/A converter, a balanced headphone amplifier and a pre-amp function. The D/A converter is based on Cirrus CS 43131 with typical 130 dB dynamic range and THD as low as -115 dB. It comes with a USB-C terminal and supports PCM signals up to 32 bits and 384 kHz sample rate as well as DSD up to 256.

The roots of the headphone amplifier circuitry can be found in its praised and rewards winning predecessors V200, V280 and V281. Inside DHA V226 is features the similar natural but smooth and pleasing sound.

Because ot its matchless technology DHA V226 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.
Therefor 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.
Therefor the ideal match for difficult to drive headphones without negative side effects and with the guarantee for a
uncompromising frequency response.

It is on you:

D/A converter? Headphone amplifier? Pre-amplifier? Any combination ? The headphone outputs or the rear line outputs can be activated/deactivated by a switch on the front. Connect not only your headphones to the DHA V226 but also your power amplifier or your active speakers and enjoy a compact and fantastic sounding headphone amplifier with topnotch D/A converter and a first-class preamplifier

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.
