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.
- 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.
- 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.
- 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)
- 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.
