FiiO K5 PRO - DAC

The XUF208 XMOS USB decoding chip equipped with clock matching management system, allows decoding up to 768kHz sampling rate and native DSD512. No matter what audio equipment you use, digital audio inherently has advantages in terms of integrity and fidelity of transmitted signals. The K5 Pro ESS allows you to take advantage of digital audio with optical and coaxial inputs that support inputs up to 96kHz, convenient for connecting various music players and digital interfaces. The K5 Pro ESS uses a DC 15V power supply designed to minimize noise. The input DC power is filtered with a secondary power supply, which then provides independent power to the amplification part of the audio circuit and the rest of the circuit. Through ADC curve reconstruction, the volume control of the K5 Pro ESS allows you to adjust the volume smoothly in extremely fine increments without any unwanted noise or channel imbalances. With K5 Pro ESS, you can comfortably use different headphones with all kinds of sensitivities. 3 Gain Levels: Low 0dB, Medium +6dB, High +10dB; 3 Input Modes: USB DAC, SPDIF IN, LINE IN Desktop DAC & Amplifier - like a USB sound card+full-size headphones; DAC for external sources, such as a USB sound card+active speakers; Powerful amplifier for mobile devices: connect your phone via USB OTG or connect your player via coaxial. In addition to the wide variety of digital inputs, the K5 Pro ESS also features a traditional analog RCA input. The RCA line-in is not only more robust and less prone to breakage than the 3.5mm line-in, but also has a better resolution. The RCA output line signal is adjustable up to a maximum of 2V, so the K5 Pro ESS can be used with a variety of active speakers and external amplifiers.
