Flex Connect


  • The ultimate in connection flexibility – balanced or unbalanced inputs & outputs in any combination.
  • Galvanic isolation delivers freedom from ground loops.
  • High-performance transformers deliver true balanced operation.
  • 4:1 impedance conversion for driving long interconnects and low-impedance amplifiers.
  • The first truly transparent attenuation for high-gain systems.
  • Excellent CMRR (Common Mode Rejection Ratio) – 110dB @ 60Hz.
  • Eliminates RFI (Radio Frequency Interference) and DC leakage.
  • Provides important ground isolation between analog and digital sources.
  • • Designed for use in the finest audiophile systems.

  • Highest quality parts used throughout.
  • Completely transparent and silent in operation.
  • Passive design requires no power supply, operates worldwide.
  • Rugged and reliable construction will last a lifetime.
  • Wide bandwidth (-3dB @ .5Hz, 150KHz), very low distortion.
  • MSRP $1895 – contact your local dealer or SMc Audio (dealer enquiries welcome).
