versione signature 6xx
potenza 52x rispetto ad un laptop tradizionale a 1600mW
Amplificatore analogico per cuffie rivoluzionario. Le tue cuffie suoneranno
come mai prima d’ora. Amplificatore completamente bilanciato progettato
con i più recenti connettori Pentaconn da 4.4 mm per ingresso e uscita.
Design del circuito derivato dal Pro iCAN e circuiti di segnale analogico
3D e XBass integrati. Caratteristiche principali: Progettazione di circuiti
analogici dual-mono bilanciati – Componenti di circuiti discreti di alta
qualità, in grado di pilotare anche carichi di cuffie difficili. Guadagno
regolabile in quattro fasi: 0dB, 6dB, 12dB, 18dB. Risposta in frequenza:
20Hz – 20kHz (+ 0dB / -0.03dB). THD & N: bilanciato <0.0007% (4V out,

A fully-discrete and balanced amplifier audio circuit. The full symmetric dual-mono headphone amplifier with gold-plated 4.4mm balanced connection. Premium engineering is more expensive but lowers the noise floor to a whisper-quiet levels. Check out the tech note for the details. As with many other iFi audio products, we’ve incorporated a custom OV Series operational-amplifier. This top-notch component contributes to the extremely low noise, low distortion (0.0001%) and wide bandwidth. Panasonic OS-CON caps totaling 5,410uF give very-low Equivalent Series Resistance (ESR), excellent noise reduction capability and frequency response characteristics. In addition, OS-CONs have a long-life span and its ESR changes little even at low temperatures since the electrolyte is solid. They are not often found in products costing <US$1000. A Tokyo Cosmos Electric Co. (TOCOS) multi-track potentiometer is used. This has close channel matching tolerance for optimal performance in quiet listening (low positions of pot). Switching between settings has been engineered to ensure sonic transparency with advanced trench technology MOSFET is used as a muting switch. This FET-based switching is handled by a micro-controller, which only ‘wakes up’ when the user changes a setting, thus eradicating any sonically deleterious interference. TDK C0G (Class 1 ceramic) capacitors offer high stability and low losses for resonant circuit applications. Getting ever closer to the theoretical ideal of pure, frequency-constant capacitance, these capacitors reduce capacitor-induced distortion to vanishingly low levels. They are pricey but are a perfect addition to our products. We use ELNA Japan Silmic II capacitors for the power supplies. The primary constituent of the newly developed dielectric is silk fibre. This material was believed as unfathomable as an aluminium electrolytic capacitor. The new material beats silk fibre and mixes it with Manila hemp fibre to provide the dielectric to an aluminium electrolytic capacitor used for high-grade music. The result is second-to-none superior acoustic properties and excellent linearity. |
