Violectric HPA V340

The Violectric HPA V340 is a reference-grade headphone amplifier and professional line preamplifier built to serve as the backbone of analytical tracking and mastering environments. Engineered around a discrete, solid-state signal path, it delivers crystal-clear, distortion-free audio. This allows mixing engineers to verify their work with absolute confidence, unmasking intricate micro-details and transients without adding any artificial tonal coloration to the source material.

50V Operating Voltage and Massive Headroom

Driving notoriously inefficient planar magnetic drivers or high-impedance studio dynamics to their full potential is a hurdle for conventional amplifiers. The HPA V340 overcomes this by operating on a specialized 50 V internal voltage rail. This robust architecture enables the amplifier to effortlessly output up to 21 V RMS into a 600-Ohm load and push an immense 5000 mW into 50 Ohms. This high-voltage topology ensures that sudden dynamic peaks and fast transients are reproduced without clipping, while a high damping factor maintains strict mechanical control over the drivers for a tight, articulate low-end response.

Pre-Gain Staging and ALPS Accuracy

Accommodating both power-hungry open-back models and hyper-sensitive in-ear monitors (IEMs) on the same amp usually forces a compromise in the noise floor. Violectric solves this with a dedicated hardware Pre-Gain system on the rear panel, allowing engineers to manually adjust the circuit's sensitivity across 7 stages (from -18 dB to +18 dB). This adjustment secures a pitch-black background, completely devoid of audible hiss. Output attenuation is handled by a premium ALPS RK27 potentiometer, providing tactile, smooth adjustments and flawless left/right channel tracking—critical for accurately evaluating stereo width and panning.
