The post Audio De-Balancer appeared first on Janus Audio.

]]> The de-balancer is an audio upgrade to convert the unbalanced audio input of vintage or consumer audio gear to a balanced audio input. It is a TRS jack with all circuitry on the jack PCB; designed to replace the unsymmetrical TS audio input in vintage and consumer studio gear.

  • Based on modern, high performance LM4562 Opamps
  • THD <0.0012%
  • headroom 20dBu
  • optional hard-wired or 100nF capacitor shield connection

Needs a true dual power supply from inside the host device with up to +/-17V in refrence to ground.

The connections on the PCB are:

  • Power +
  • Power –
  • Ground
  • Audio Out

Tested with: Alesis Quadraverb, Lexicon LPX-1, dbx 163A and more.

You can find the corresponding audio output stage here https://janus-audio.com/product/balancer/
