The K5 Pro ESS desktop amplifier allows you to take advantage of digital audio with optical and coaxial inputs supporting up to 96kHz inputs, convenient for connecting various music players and digital interfaces. RCA line-out for high quality output to other sources Besides the wide variety of digital inputs, the K5 Pro ESS portable DAC also features a traditional analog RCA line-out. RCA line-out is not only more robust and less prone to breakage than 3.5mm line-in, it also has better resolution. The RCA line-out line signal is adjustable up to a maximum of 2V, so the K5 Pro ESS headphone amps can be connected with a variety of active speakers and external amplifiers. PS: When using the line out, please disconnect your headphones. Front of K5PRO ESS amps A. Input(coax/optical/line in/usb in); B. Gain(high/mid/low); C. Power/Volume knob; D.

You could use it to drive the headphones of 600Ω We recommended headphone impedance is 16-300ohm, but it can drive more higher impedance even like 600ohm, easily powers any full-size headphones. It means K5 Pro ESS amplifier can drive most of the headphones selling in the market. 3 gain levels Both the input selection and gain are controlled by tactile toggle switches, which are clearly labelled allowing you to easily control your music. Low, medium, and high gain levels are available allowing you to use the K5 Pro ESS amps with almost any headphone at comfortable volume levels. A pure hardware gain circuit is used at low gain, with unaffected and uncompromised dynamic range and overall music fidelity. Accurate volume adjustment Through reconstruction of the ADC curve, the desktop headphone amps K5 Pro ESS’s volume control allows you to smoothly adjust volume at extremely fine increments without any undesirable noise nor with any channel imbalances. With the K5 Pro ESS amplifier, you can comfortably use various headphones with all kinds of sensitivities.Safe, secure, and robust power supply The K5 Pro ESS headphone amps uses a DC 15V power supply designed to specifically minimize noise. The incoming DC power is filtered with a secondary power supply, which then independently supplies power to the amplification part of the audio circuit and the rest of the circuit. This effectively suppresses power supply ripple and minimizes power supply crosstalk between the two major sections of the circuit, for a more stable and less noisy power that is crucial for outstanding sound for such a precisely-designed high performance audio architecture For a true high-fidelity sound When it comes to amplification, the K5 Pro ESS DAC is no slouch. The K5 Pro ESS amplifier has generous space to fit and package the necessary components for exceptional analog amplification, and packs a four-level audio circuit capable of providing extraordinary audio fidelity in its class: second-order LPF + analog volume adjustment + voltage amplification + current drive. Each part of the amplification circuit works perfectly together in harmony for excellent dynamic range and high resolution of sound. Volume knob & RGB light indicator The volume knob allows you to easily and comfortably control volume. The RGB light indicator that surrounds the volume knob lights up with different colors according to the current sample rate.

Headphone adapter*1 FAQ for K5 PRO ESS Amplifier What needs to be noted when using K5 Pro ESS? (1) Please adjust the knob to the minimum volume before each listening, then adjust to the volume that suits you. (2) Please insert the power supply and input signal before putting on the headphones. (3) Try not to use inferior cables. After the K5 Pro ESS is plugged in, it will feel numb to touch the body with your hands. Is this a leakage, is it normal? Because K5 Pro ESS is a Class II device, it is the same as a desktop computer. In some cases, it may feel numb when you touch the body during use. This is normal and does not cause any safety impact. And laptops that are charging will often encounter this problem. K5Pro ESS's adapter has also passed the safety certifications of China, Japan, South Korea, Europe, the United States, and many other countries, and the quality is no problem. It should be noted that the selection of the K5 Pro ESS's power supply is an optimal result after comprehensive consideration of multiple objective phonemes such as product startup, sound quality, indicators, reliability, certification, and cost. The current power adapter, among all the adapters in our experiments, has the lowest noise, the highest startup success rate, and the best indicators. So please rest assured. Can the headphones out and line out work at the same time? Is the line out output amplitude adjustable? Can it be used as a pre-AMP? The headphones out and line out can work at the same time, and the amplitude can be adjusted. However, the line out output is up to 2Vrms. It is possible to connect an integrated amplifier or an active speaker, but it is not enough to use with the pure power stage amplifier as the preamp. How to play DSD format when the K5 Pro is connected with the computer? There is an example of the Foobar2000(v1.3.8) installed on Windows computer in our official website, please google "fiio" to check it out. And iOS device users are required to buy the musicapplication program which can support DSD format, such as Audirvana Plus. Do I need to install a driver to connect it with my computer? Yes, and you can go to our official website to download the driver. Which "Gain" should I use with my headphones? Choose the gain setting with your earphones such that a comfortable listening volume lies somewhere between 9 and 3 o'clock on the volume knob. What is the priority level when selecting the Spdif input, if the optical and coaxial input are inserted at the same time? Coaxial input will be the priority.
