Aimed at audiophiles and music enthusiasts, the high-fidelity FiiO K7 BT is a compact desktop USB DAC and balanced headphone amplifier designed to faithfully reproduce your music when listening to audio from your computer, smartphone/tablet, or other digital music player. The K7 BT employs dual high-resolution AK4493S DACs to deliver rich audio details and a superior performance at up to a 384 kHz sampling rate supporting native DSD256. Dual THX AAA 788+ amp chips deliver powerful, nuanced sound.
Equipped with RCA analog line inputs, optical and coaxial digital inputs, a USB Type-B port, RCA analog line outputs, and two headphone jacks, the K7 BT acts as a bridge between your computer, phone, speakers, and headphones, allowing them to work together seamlessly. Further enhancing this function is the handy Bluetooth 5.1 functionality, courteously of the Qualcomm QCC5124 Bluetooth chip, which supports hi-res Bluetooth formats for low-latency wireless audio streaming. Switchable low- and high-gain levels are available, enabling you to use the amplifier with almost any headphones at comfortable volume levels. Constructed from durable aluminum alloy, the elegant design is just over 2" thick, allowing you to easily place it on modern desktops and workstations.
A New Baseline for Balanced Desktop Sound
- The K7 BT has a six-stage audio circuit with balanced analog and digital sections, helping to reduce crosstalk and accurately reproduce your music for a more enjoyable listening experience.
- Using the same THX AAA 788+ amplifiers as the K9 Pro, the K7 BT is capable of outputting 560mW into a 300-ohm load at 1% distortion. This ensures both low- and high-impedance headphones are powered properly.
Dual AK4493SEQ Chips for Precise DAC
The left and right channels are each equipped with an efficient high-performance AK4493SEQ digital-to-analog converter to provide nuanced and delicate reproduction of your favorite music.
Robust Decoding Capabilites
The XMOS XUF208 decoder chip uses dual clock management to handle various music formats with ease, allowing you listen to many audio formats.
Large Volume Knob + RGB Indicator Lights
- The large volume dial provides precisely tuned gain control over a smooth 112 steps of adjustment.
- The RGB indicator lights are capable of displaying single colors as well as mixed colors, with a unique light flow effect during powering on/off and input switching. Dazzling and vivid light effects add visual spice to your desktop.
- The high- and low-hardware gain levels allow you to easily adjust the K7 BT to handle headphones of various impedances and sensitivities for rich and consistent listening.
HD Bluetooth for a Reassuring Wireless Experience
The Bluetooth version of the K7 uses a QCC5124 Bluetooth chip, supporting high-definition Bluetooth 5.1 formats like LDAC, aptX HD, and aptX Adaptive. When using the K7 BT, switch the input mode to Bluetooth, and you will enjoy low-latency Bluetooth transmission and hi-res sound quality. Plus, the convenient app controls help to further enhance your wireless experience.
A Variety of Inputs and Outputs in One Place
- Two headphone outputs are provided, a 1/4" unbalanced jack and a 4.4mm balanced connector.
- Unbalanced RCA line inputs and output connectors, along with coaxial, optical, and USB digital connectors are on the rear panel
- One key controls switching between the four different inputs, while a second key allows you to switch between three different output modes (for use with headphones, speakers, or as a DAC)
Robust External Power Supply
- The K7 BT features a power design consisting of multiple independent stages, with a voltage of each regulated by low-noise LDOs.
- Feeding this power design is an external 12V switching power supply, engineered to provide plenty of clean power for your sonic enjoyment.
