FiiO JM21, nešiojamas Hi-Res muzikos grotuvas

FiiO JM21 - kompaktiškas Hi-Res nešiojamas muzikos grotuvas (DAP), sukurtas aukštos kokybės garso mėgėjams. Jame naudojamas Qualcomm Snapdragon 680 procesorius, du Cirrus Logic CS43198 DAC, pilnai subalansuota garso grandinė ir Android 13 operacinė sistema. Palaikomi aukštos raiškos garso formatai, Bluetooth LDAC, Wi-Fi transliavimas, USB DAC funkcija bei 3,5 mm ir 4,4 mm ausinių išėjimai, todėl JM21 užtikrina puikią garso kokybę tiek namuose, tiek kelionėse. Procesorius: Qualcomm Snapdragon 680 (8 branduolių, 6 nm) DAC: 2 × Cirrus Logic CS43198 su pilnai balansine garso grandine Išėjimo galia: iki 700 mW + 700 mW (4.4 mm balansinis išėjimas, 32 Ω) Ekranas: 4,7" HD (750 × 1334) jutiklinis ekranas Hi-Res palaikymas: iki 384 kHz / 32 bit ir DSD256 (vietinis atkūrimas / USB DAC) APRAŠYMAS Portable High-Res Lossless Music Player New octa-core 6nm Snapdragon 680 | Fully balanced audio design | 13mm ultra-thin body Dual Cirrus Logic CS43198 DACs | Dual SGM8262 op-amps | Dual custom femtosecond crystal oscillators | Android 13 | Up to 700mW + 700mW output power | 4.7-inch HD display | Up to 16-hour battery life | Proprietary DAPS system without global SRC | 3.5mm + 4.4mm outputs | SPDIF / USB / Line Out audio outputs Powerful Performance with Snapdragon 680 The FiiO JM21 is powered by the Qualcomm Snapdragon 680 octa-core processor, manufactured using an advanced 6nm process. With clock speeds up to 2.4GHz, it delivers smooth performance, lower power consumption, and a responsive Android 13 experience for music playback and streaming applications. Dual Flagship DAC Architecture Two Cirrus Logic CS43198 DAC chips independently process the left and right audio channels in a fully balanced design. Combined with dual SGM8262 operational amplifiers, segmented power supplies, and isolated circuit architecture, the JM21 delivers a wider dynamic range, lower distortion, and highly detailed sound reproduction. Precision Clocking for Pure Audio The JM21 utilizes dual custom femtosecond crystal oscillators together with a 5th-generation FPGA to ensure highly accurate clock synchronization. This minimizes jitter and guarantees bit-perfect playback with no unwanted sample-rate conversion when playing local files or streaming music. Android 13 with Pure Audio Architecture Running a deeply customized Android 13 operating system, the JM21 supports popular streaming music services while maintaining lossless audio quality through FiiO's proprietary DAPS (Digital Audio Purification System), which bypasses Android's global SRC. Powerful Balanced Output Despite its ultra-thin 13 mm chassis, the JM21 delivers up to 700mW + 700mW through its balanced 4.4 mm output, making it suitable for both in-ear monitors and demanding over-ear headphones. Three gain settings and three dedicated volume curves ensure optimal matching with different headphones. High-Resolution Wireless Connectivity The JM21 supports Bluetooth 5.0 with high-quality codecs including LDAC, LHDC, aptX HD, aptX, AAC, and SBC for wireless transmission, while also supporting Bluetooth reception with SBC, AAC, and LDAC. Versatile Connectivity The player features multiple analog and digital outputs, including: 3.5 mm headphone / Line Out / Coaxial output 4.4 mm balanced headphone / Line Out USB DAC mode USB Audio output SPDIF digital output It can also function as a USB DAC supporting up to 384kHz / 32-bit audio. Long Battery Life With optimized power management, the JM21 offers extended playback time: Up to 16 hours (4GB + 64GB model, single-ended output) Up to 12.5 hours (balanced output) Fast charging via USB-C.
