أعلنت شركة Chord Electronics عن محول الإشارات الجديد QUTEST المنفصل. محول الإشارة QUTEST هو محول إشارات DAC مكتبيّ ثابت صنع خصيصاً ليحلّ محل محول الإشارات 2Qute من نفس الشركة والحائز على العديد من الجوائز العالمية. محول الإشارة Qutest مصمم لتدعيم جودة الصوت في المنزل وكونه منفصلاً يعني أنه لا يحتوي على أي مضخم صوت مخصص للسماعات أو بطاريات قابلة للشحن.
محول الإشارات هذا مبني على تقنية FPGA من شركة Chord والتي حصدت العديد من الجوائز؛ هذه التقنية أطلقت لاول مرة في جهاز Hugo 2 أحد أشهر محولات/مضخمات الصوت التي أطلقتها الشركة. تساهم هذه التقنية في رفع مستوى الأداء الصوتي للجهاز بشكل عام وتحسن الأداء التقنيّ.
محول إشارة عالي الدقة: قادر على تشغيل الملفات ابتداءاً من 44.1kHz وحتى جودات الصوت العالية الخاصة بالاستوديوهات 768kHz و DSD512.
Qutest is our ‘pure’ DAC (it does not contain headphone amplification or rechargeable batteries like some of its range stablemates) and is designed to improve sound quality in the home. It is the latest evolution of our most affordable standalone DAC, the multi-award-winning 2Qute, which it directly replaces. | |
Qutest, which is a What Hi-Fi? Star of CES 2018, is based on our award-winning proprietary FPGA technology developed for the class-leading Hugo 2 DAC/headphone amp, giving it proven class-leading technical and sonic performance. Perfectly equipped to bring the benefits our digital technology to a wide range of connected devices, it features a galvanically isolated USB-B, optical and coaxial digital input, giving an instant performance upgrade, plus the ability to modernise ageing digital source components. | |
The Qutest chassis is all-new, too. It has significantly greater mass than its predecessor and has been precision-machined from solid aircraft-grade aluminium billet. The Qutest PCB nestles within a shallow cavity in the solid aluminium chassis, giving the circuit board greater protection within the casework and additional isolation from external vibration compared to previous designs. | |
