Utilizing discrete solid-state architecture and an exceptionally high internal operating voltage, this unit offers uncolored transparency and lightning-fast transient response, providing an analytical window into your mix without imposing any sonic signature of its own.\u003c\/p\u003e\n\n\u003ch3 style=\"text-align: center;\"\u003eRelay-Controlled Volume and Phase Perfection\u003c\/h3\u003e\n\u003cp\u003eTraditional carbon-track potentiometers inherently suffer from channel imbalances at lower volume settings, severely compromising spatial imaging and the accurate assessment of reverb tails. The PRO version of the V550 completely bypasses this limitation by utilizing a sophisticated 256-step resistor ladder network controlled by premium reed relays. Adjusting the signal in exact 0.4 dB increments, this mechanism guarantees flawless left\/right channel matching and phase coherence at any attenuation level. This level of mathematical precision is mandatory for mastering engineers evaluating stereo width and subtle panning moves.\u003c\/p\u003e\n\n\u003ch3 style=\"text-align: center;\"\u003e50V Operating Voltage and Pre-Gain Flexibility\u003c\/h3\u003e\n\u003cp\u003eProperly driving inefficient planar magnetic headphones or high-impedance dynamic studio monitors requires massive dynamic headroom. The HPA V550 PRO operates on a 50 V internal voltage rail, allowing it to swing up to 21 V RMS into 600 Ohms and deliver 6400 mW into 50 Ohms. This specific topology completely prevents transient clipping and dynamic compression. To accommodate this immense power across all headphone types without raising the noise floor, the amplifier features a hardware Pre-Gain system. Engineers can adjust the internal gain staging in 7 steps (from -18 dB to +18 dB), ensuring a pitch-black background even when using hyper-sensitive in-ear monitors (IEMs).\u003c\/p\u003e\n\n\u003ch3\u003eKEY FEATURES\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAdvanced 256-step relay-controlled resistor ladder (0.4 dB increments) ensuring flawless channel balance and spatial imaging.\u003c\/li\u003e\n\u003cli\u003eMassive output stage yielding 6400 mW (50 Ohms) and 21 V RMS (600 Ohms) via an internal 50 V operating voltage.\u003c\/li\u003e\n\u003cli\u003eHardware Pre-Gain adjustment system to perfectly match the amplifier's sensitivity to anything from delicate IEMs to demanding planars.\u003c\/li\u003e\n\u003cli\u003eExceptionally high damping factor providing strict mechanical control over headphone drivers for precise, tight bass response.\u003c\/li\u003e\n\u003cli\u003eComprehensive line preamplifier capabilities, fully manageable from the tracking position via the included remote control.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTECHNICAL SPECIFICATIONS\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eDevice Type: Solid-state headphone amplifier \/ line preamplifier\u003c\/li\u003e\n\u003cli\u003eAnalog Inputs: 1x Balanced XLR, 2x Unbalanced RCA\u003c\/li\u003e\n\u003cli\u003eLine Outputs (Pre-Out): 1x Balanced XLR, 1x Unbalanced RCA\u003c\/li\u003e\n\u003cli\u003eHeadphone Outputs: 1x 4-pin XLR (Balanced), 1x 4.4 mm Pentaconn (Balanced), 1x 6.3 mm \/ 1\/4\" Jack (Unbalanced)\u003c\/li\u003e\n\u003cli\u003eMaximum Output Power: 6400 mW (50 Ohms)\u003c\/li\u003e\n\u003cli\u003eMaximum Output Voltage: 21 V RMS (600 Ohms)\u003c\/li\u003e\n\u003cli\u003eVolume Control: 256-step relay-controlled resistor ladder (PRO version exclusive)\u003c\/li\u003e\n\u003cli\u003ePre-Gain Adjustments: -18, -12, -6, 0, +6, +12, +18 dB\u003c\/li\u003e\n\u003cli\u003eRemote Control: Infrared remote included\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Violectric","offers":[{"title":"Default Title","offer_id":53436252062033,"sku":"58010","price":2788.28,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8741\/0769\/files\/ViolectricHPAV550PRO1.jpg?v=1775648009","url":"https:\/\/wrdtunes.com\/products\/violectric-hpa-v550-pro","provider":"Wired Tunes","version":"1.0","type":"link"}
