Violectric Niimbus US 5
Elegir opciones
The Violectric Niimbus US 5 is a reference-grade headphone amplifier and line preamplifier meticulously engineered for critical mastering applications and high-end studio playback. Operating on a fully balanced dual-mono architecture with an exceptionally high internal voltage, it provides an analytical window into your mix, extracting transients and micro-details with surgical precision while retaining absolute tonal neutrality.
Massive Headroom and Pre-Gain Staging
Effectively driving notoriously inefficient planar magnetic headphones while simultaneously accommodating highly sensitive in-ear monitors (IEMs) requires extreme dynamic flexibility. The Niimbus US 5 outputs a staggering 7000 mW into 50 Ohms and up to 32 V RMS into a 600 Ohm load. To perfectly manage this immense power reserve, the amplifier relies on a dedicated Pre-Gain architecture. Tracking and mastering engineers can adjust the internal gain staging from -18 dB to +18 dB, optimally matching the amplifier's noise floor to the specific transducer for a pitch-black background.
Pristine Signal Path and ALPS Control
Accurate attenuation is critical for evaluating stereo width and depth in a studio environment. The US 5 incorporates a premium, motorized ALPS RK27 potentiometer, delivering smooth, tactile volume adjustments with highly reliable channel tracking. This component ensures that phase coherence and stereo imaging remain perfectly intact even at lower listening volumes. Combined with its robust line preamplifier capabilities and a comprehensive remote control, the US 5 serves as a centralized, uncolored command station for demanding analog routing.
