The Violectric DHA V5902 is a powerful monitoring combination of headphone amplifier, D/A converter and preamplifier. Digital audio signals are fed in via XLR, RCA, USB or optical input, translated into the analog world by ESS-Tech ES9026 PRO converters and played out on up to three different headphones. Formats up to 384 kHz and DoP can be converted. Elegant ALPS controls regulate the volume and balance.
The pre-gain circuit adjusts the level to the impedance of the headphones being used. The carefully selected components are installed by hand in a high-quality housing with a wide range of connection options. The Violectric DHA V5902 is therefore perfectly suited as the central element of a home audio system.
An included remote control offers maximum ease of use.

Balanced headphone outputs
When listening to music via loudspeakers, you are part of the auditorium. When listening via “normal” headphones, you take the place of the conductor. When listening with “balanced” headphones, you are part of the orchestra.
If headphones are operated symmetrically, the channel separation is increased even further. Balanced headphones usually have a 4-pin XLR connection or a Pentaconn plug. True balanced operation requires a great deal of effort in the form of four built-in power amplifiers.
PRE-GAIN
The headphone amplifier is positioned between the music source and the headphones. The source can be of varying power and the headphones of varying sensitivity. The Lake People PRE-GAIN serves to compensate for these differences and to optimize the headphone amplifier for every conceivable combination. This results in minimal noise, the lowest distortion factor and the best channel balance.
The PRE-GAIN adjustment is located on the rear of the Violectric HPA V340 and can be set individually in 7 stages (-18, -12, -6, 0, +6, +12, +18 dB)
Perfect headphone protection
Various circuits protect the headphones from unclear operating states, DC voltage, excessive operating temperature and overload:
Delayed ON, Instant OFF
Every headphone amplifier causes interference when it is switched on and off. This interference can damage the connected headphones. The headphones are connected to the amplifier with a delay via relays and the associated electronics and disconnected again immediately after switching off. In this way, the headphones themselves are protected from the device electronics as long as no clearly defined conditions are to be expected.
DC monitoring
The outputs are monitored for harmful DC voltage. As soon as a predefined value is exceeded, the headphones are switched off.
Overload monitoring
The power consumption is constantly measured during operation. If predefined parameters are exceeded, the headphones are switched off.
Remote control
Control the Violectric DHA V590² remotely with its beautifully designed remote control milled from a solid piece of metal. Infrared gives you access to the most important functions of the device:
Volume
Mute
Input selection (XLR / RCA1 / RCA2)
Output selection (headphones / LineOut)
Violectric's unique technology
Lowest noise - thanks to very low internal amplification. This means that the amplifier's own noise is inaudible.
High output voltage - due to an internal 50 volt operating voltage. Therefore ideally suited for high-impedance headphones.
High output power - thanks to powerful amplifiers that can deliver far more power than even the most demanding headphones require. Therefore ideally suited for headphones with low impedances and magnetostats.
High damping factor - due to the lowest output impedance. Therefore ideally suited to drive even the most difficult headphones without interference. The advantage for an uncompromising frequency response.
