Lab Overview


  • functions as both a high-quality phono preamp + recording interface for recording vinyl or any other line-level input
  • audiophile-grade, Burr Brown A/D (analog to digital) converter for high quality recording; analog RCA or USB recording output to computer
  • dual inputs: phono (MM or MC switchable) + line level switchable with front-panel selector
  • adjustable analog gain knob on front panel for fine-tuning input signal (pre-A/D)
  • ultra low noise & low distortion levels, SMD circuitry
  • high quality metal casing offers shielding from both vibration and electromagnetic interference

"The AD Box S2 Phono is a dual function preamp that is recommended for those who will want to record / playback an analog source into their computer. It has the best of both worlds with separate analog and digital circuitry running parallel. The analog gain knob works before the A/D conversion, so you can fine tune your recordings before the conversion." - TTL
