High Resolution Desktop Audio

Output options include RCA, 3.5mm headphone output, and 4.4mm balanced headphone output, giving users a clean path to headphones, powered speakers, or a separate amplifier. Bluetooth 5.0 support with SBC, AAC, aptX, aptX HD, and aptX LL codecs adds wireless playback flexibility for daily listening.
Controls Built for the Desk
Dual large control knobs, shortcut buttons, a high-resolution display, and an angled aluminum alloy chassis make the K7 easy to operate during music, gaming, streaming, and work sessions. The included USB-A/C to USB-C cable, Bluetooth antenna, Y-splitter cable, DC 12V power supply, and user manual help complete the desktop setup.
