Violectric HPA V324

The Violectric HPA V324 is a fully balanced headphone amplifier and reference line preamplifier engineered specifically for rigorous mastering environments and high-fidelity analytical listening. Utilizing proprietary TRUE-BALANCED technology driven by four discrete amplifier stages, this unit delivers an exceptionally clean signal path, an ultra-low noise floor, and strict tonal neutrality, allowing mixing engineers to evaluate their tracks with absolute uncolored precision.

Massive Headroom and Front-Panel Pre-Gain

Driving highly inefficient, large-format planar magnetic headphones while simultaneously ensuring a pitch-black background for sensitive in-ear monitors (IEMs) requires extreme gain stage flexibility. The HPA V324 achieves this by delivering a massive 5000 mW into a 50-Ohm load and swinging up to 21 V RMS into high-impedance 600-Ohm dynamic drivers. A standout workflow improvement over its predecessors is the relocation of the hardware Pre-Gain control directly to the front panel. A tactile 6-step rotary switch (ranging from -18 dB to +12 dB) allows users to instantly optimize the amplifier's internal sensitivity for any transducer, entirely eliminating audible background hiss without reaching behind the rack.

Illuminated VU Meters and ALPS Precision

Continuous visual monitoring of input levels without constantly glancing at your DAW meters is a major workflow enhancement. The V324 features dual analog, continuously dimmable VU meters on the front panel that provide immediate feedback on your gain structure. Output attenuation is handled by a premium, motorized ALPS RK27 potentiometer. This audiophile-grade component offers smooth, tactile resistance and flawless left/right channel tracking—critical for preserving phase coherence and evaluating exact stereo width during the mixing process. Comprehensive preamplifier capabilities allow engineers to easily route and manage active studio monitors directly from the tracking position via the included infrared remote control.
