FiiO QX13 - aukštos klasės nešiojamas USB DAC ir ausinių stiprintuvas, skirtas ieškantiems galingo ir detalaus garso. Jis aprūpintas ESS ES9027SPRO DAC, palaiko PCM 768 kHz/32 bit, DSD512 ir MQA, o iki 900 mW išėjimo galia leidžia lengvai valdyti tiek jautrias, tiek reiklias ausines. DAC: ESS ES9027SPRO (vienas DAC su 8 lygiagrečiais kanalais) USB procesorius: XMOS XU316 Išėjimai: 3,5 mm + 4,4 mm balansuotas Ekranas: 1,99" IPS APRAŠYMAS Portable Hi-Res USB DAC & Headphone Amplifier The FiiO QX13 is a flagship portable USB DAC and headphone amplifier designed for music enthusiasts who expect desktop-class audio performance in a compact, travel-friendly device. Built with premium components and advanced audio engineering, it delivers exceptional clarity, powerful output, and support for the latest high-resolution audio formats. Desktop-Class Audio Performance At the heart of the QX13 is the ESS ES9027SPRO, a flagship SABRE PRO digital-to-analog converter commonly found in high-end desktop audio equipment. Combined with an advanced fully differential circuit design and parallel audio channels, it provides outstanding resolution, low distortion, and impressive dynamic range. Powering the digital section is the XMOS XU316 16-core USB processor, enabling support for PCM up to 768 kHz / 32-bit, native DSD512, and MQA full decoding for uncompromised high-resolution playback. Powerful Amplification The analog stage features four TI INA1620 headphone amplifier chips together with two OPA1692 low-noise operational amplifiers. This carefully optimized design delivers excellent channel separation, wide soundstage, and stable performance across a wide range of headphones. In Desktop Mode, the balanced 4.4 mm output can provide up to 900 mW per channel at 32 Ω, making the QX13 capable of driving many demanding over-ear headphones while maintaining excellent efficiency and low power consumption. Intelligent Desktop Mode FiiO's patented Desktop Mode automatically analyzes the available USB power source and intelligently adjusts amplifier gain and output power. This ensures the best balance between maximum performance, thermal stability, and energy efficiency without requiring manual adjustments. Advanced Circuit Design To minimize interference, the QX13 separates its digital and analog sections onto independent circuit boards protected by dedicated shielding. Multi-layer construction improves signal purity while enhancing heat dissipation, allowing the amplifier to maintain stable high-power operation during extended listening sessions. Professional Sound Customization The QX13 includes a 10-band high-precision parametric equalizer (PEQ), allowing detailed sound tuning through the FiiO Control app or FiiO's web-based PEQ interface. Users can create personalized sound profiles while preserving audio quality. Premium Display and User Interface A bright 1.99-inch IPS color display protected by Corning third-generation strengthened glass provides easy access to playback information and device settings. Multiple interface themes allow users to personalize the appearance in both portrait and landscape orientations. Premium Carbon Fiber Construction The Carbon Fiber version uses multiple layers of genuine carbon fiber to create a lightweight yet highly durable enclosure. Besides reducing weight, the material offers excellent rigidity, improved heat resistance, and reduced electromagnetic interference while providing a distinctive premium finish. An aluminum alloy version is also available. Excellent Connectivity The QX13 supports both 3.5 mm single-ended and 4.4 mm balanced headphone outputs. The 3.5 mm connector also functions as an SPDIF digital output, allowing the device to connect to compatible external DACs and audio systems. The USB Audio interface supports plug-and-play operation with Windows, macOS, Android, iOS, Nintendo Switch, PlayStation 5, and many other compatible devices. Designed for Portable Hi-Fi Included with the QX13 is a magnetic leather case that aligns perfectly with MagSafe-compatible iPhones. Android users can achieve similar functionality using the supplied magnetic ring. The package also includes a premium 8-strand USB-C cable made with monocrystalline copper and silver-plated conductors for reliable signal transmission.
