Violectric HPA V324 – Balanced Reference-Class Headphone Amplifier with Preamplifier Function

The Violectric HPA V324 is a reference-class premium headphone amplifier with an integrated preamplifier function, designed for the most demanding users – whether in professional environments or for audiophiles. Thanks to advanced TRUE-BALANCED technology, four independent amplification stages, remote control, balanced and unbalanced outputs, and uncompromising sound quality, this unit becomes the central hub of any audio system. The HPA V324 combines innovations from Lake People, Violectric, and Niimbus into one superior device.

Product Features

• TRUE-BALANCED – 4 amplifier stages for perfect channel separation
• Analog inputs: XLR (balanced) and RCA (unbalanced), switchable from the front panel
• Headphone outputs: 4-pin XLR, 4.4 mm Pentaconn, 6.3 mm jack
• Line outputs: RCA and XLR, switchable between HEAD / OFF / LINE
• PRE-GAIN adjustment from -18 to +12 dB in 6 steps
• Motorized volume control – ALPS RK27 with remote
• Backlit, adjustable VU meters
• High output power – up to 5000 mW at 50 Ohms
• Extremely low output impedance – 0.3 Ohm / 0.15 Ohm

Uncompromising Perfection

The HPA V324 stands out with extraordinary signal purity, offering a dynamic range over 131 dB (A), a frequency response of 5 Hz to 150 kHz, and extremely low self-noise (<102 dBu A). Thanks to a high internal operating voltage (50 V) and powerful output stages, it is ideal for both low- and high-impedance headphones, including planar models. Precise volume control and extensive protection circuits ensure safe and controlled listening at the highest level.
