Box X5 Phono Preamp

Embrace the Vintage Charm of Vinyl with Modern Precision

Supporting MM/MC cartridges, BOX X5 is compatible with most turntables, along with 4 adjustable gain levels of 38/48/56/66 dB. It utilizes high-precision capacitors and resistors, ensuring minimal noise for audio purity. Intuitive RCA terminals achieve a plug-and-play experience.

  • Input: MM/MC RCA; Output: RCA
  • SNR≥92dB; THD≤0.009%
  • Frequency Response: 20Hz-20kHz(±0.015dB)
  • Power Adapter: AC 16V; Input voltage:120V

  • Grounding is recommended to avoid rattling during use.

  • The BOX X5 is a phono preamp with a higher amplification gain than a regular preamp, thus it is not suitable for use as a standard preamp.

  • Power On: Turn on the turntable, then the BOX X5, followed by the amplifier.

    Power Off: Turn off the amplifier, then the BOX X5, and finally the turntable.
