Fiio K11 Επιτραπέζιος Ψηφιακός Ενισχυτής Ακουστικών Καναλιών με DAC, USB και Jack 6.3mm

Το FiiO K11 είναι ένας ευέλικτος ενισχυτής USB DAC και ακουστικών. Στην πλευρά του DAC, ένα τσιπ CS43198 και ο ελεγκτής GD32F303RET6 του επιτρέπουν να υποστηρίζει αρχεία υψηλής ανάλυσης έως PCM 32 bit 384 kHz και εγγενή DSD έως και DSD256. Όσον αφορά το στάδιο του ενισχυτή ακουστικών, το FiiO έχει εξοπλίσει το K11 του με υψηλό επίπεδο ισχύος. έως 520mW @32Ω στην μη ισορροπημένη έξοδό του και έως 1400mW @32Ω στην ισορροπημένη έξοδό του. Αυτό το καθιστά συμβατό με μεγάλο αριθμό ακουστικών και ακουστικών στην αγορά με σύνθετες αντιστάσεις μεταξύ 16Ω και 350Ω. Το FiiO K11 ενσωματώνει επίσης μια μεγάλη γκάμα υποδοχών, με οπτική είσοδο Toslink, ομοαξονική είσοδο SPDIF, έξοδο στερεοφωνικής γραμμής RCA και ομοαξονική έξοδο SPDIF, επιτρέποντάς του να ενσωματώνεται εύκολα σε οποιαδήποτε εγκατάσταση Hi-Fi.

FiiO K11 : A high-performance DAC with volume

Thanks to its wide range of connectors, the K11 is able to accept a wide range of sources. Its asynchronous USB-C input, combined with the GD32F303RET6 controller and CS43198 DAC chip, enables it to support high-resolution files up to PCM 32bit 384kHz and native DSD up to DSD256, whether they come from your computer, smartphone, tablet or game console, for example.

FiiO K11 : Powerful amplification circuitry and low-noise power supply

As mentioned above, the K11 is capable of delivering a powerful audio signal on its headphone outputs, with 520mW @32Ω on its unbalanced 6.32mm jack output and up to 1400mW @32Ω on its balanced 4.4mm jack output. Its amplification circuitry enables it to achieve a distortion level of just 0.0009%. The entire K11 circuit is powered by a stable supply of no less than 16 low-noise LDOs.

FiiO K11 : Three adjustable gain levels

FiiO has equipped its KI11 with three separate gain levels, each with its own volume level adjustment curve. This allows you to enjoy the best listening experience whether your headphones or earphones are sensitive or difficult to control.

FiiO K11 : A refined look

The front panel of the K11 features an attractive LCD display showing information on the resolution of the file being played, the volume and gain levels, and the input source.

An enlightened logo for the FiiO K11

On the top of the K11, the FiiO logo is illuminated by various LEDs whose brightness, color and light pattern animations can be adjusted.
