• Output power: 21V RMS (600Ω), 5000mW (50Ω)
• Pentaconn output.

Thanks to the innovative technologies applied in the Violectric amplifier, it has become the winner of numerous tests among headphone amplifiers. The amplifier in the DHA V380 V2 was designed to provide maximum sound quality for headphones with any impedance. Thanks to technology specially optimized for dynamic headphones, it was possible to minimize noise in the circuit and achieve a low level of distortion to meet the high demands of Hi-End.

The internal circuitry operates with low sensitivity, providing minimal internal circuit noise that is practically imperceptible to the ear during listening. The internal voltage level of the circuit is increased to 50 volts, making the amplifier an ideal partner for headphones with a high impedance level. Over 90 percent of amplifiers on the market operate with an internal voltage more than half of that of the DHA V380 V2. This model features a discrete, separate amplification circuit with eight transistors per channel.

Thanks to its wide connectivity options, the Violectric DHA V380 V2 has exceptional versatility. Optical connection, USB port, and coaxial input are available as digital inputs. Analog inputs consist of two unbalanced stereo RCA inputs. Analog outputs are divided into balanced and unbalanced connectors. And for headphones, the front panel provides balanced 4.4mm and XLR connectors, as well as the classic 6.3mm.

The V380 V2 has balanced (XLR) and unbalanced (RCA) outputs with adjustable level (preamp output), which can be used simultaneously. The output gain can be adjusted in several steps, and the RCA outputs can also be configured as fixed level outputs (FixOut). There are three unbalanced line inputs (RCA) available.

The manual volume control with the RK 27 potentiometer (Made in Japan) allows for adjusting the balance between channels and provides clean sound with minimal interference from crosstalk. The built-in power supply, with no noise or humming, utilizes a toroidal transformer and high-capacity capacitors.

As a special function for the unbalanced output (RCA), a "pre fader" or "post fader" can be installed. "Post fader" means that the volume control affects the output signal level. "Pre fader" means that the buffered input signal is directed unchanged to the unbalanced output (RCA). This setting can be useful when the unbalanced output (RCA) is connected to a device with its own volume control, such as a headphone amplifier.

After selecting the input with a special controller, the signal is sent to a buffer amplifier to achieve a low impedance state. The signal then goes through the volume control, followed by another buffer amplifier. Finally, the signal reaches the output operational amplifiers, which can be adjusted to different output levels using internal mini switches.

Depending on the type of headphones, the level adjustment can be carried out using the pre-amplification switches on the rear panel of the amplifier.

The exceptional build quality ensures excellent listening experience. With multiple connection and routing options, V380 V2 is the perfect central control element in a complex home audio system.

To meet high Hi-End standards, Violectric consistently pays great attention to component selection and processing. The signal, after conversion using the ES9026 PRO chip, passes through the Alps RK27 volume control with eight transistors for unbalanced headphone amplifier channels and sixteen transistors for the balanced channel.

Additional circuits protect the devices from direct current, overload, or overvoltage and delay the power-on process to safeguard the headphones. All components are meticulously assembled by hand and housed in a sleek black anodized aluminum enclosure with a millimeter-thick front panel.

Changes in version V2

The updated version no longer has a switchable resampler. Instead of the second 6.3 mm output, a balanced 4.4 mm Pentaconn output has been added.

Package includes:

• DAC with amplifier
• Power cable
