Read before using the profile

  • One passive mono direct box; no power required in the specifications.
  • The instrument thru is documented separately in the manufacturer source, but is not offered as an additional converted output here.
  • A signal-ground lift control is not permission to alter mains protective earth.
  • Same-publisher output-impedance conflict: specifications 150 ohms versus features 600 ohms. No impedance value is used for a connection verdict.

ProDI signal roles and manufacturer disagreement.

Open source ↗

Locator: Instrument input, thru, balanced output and ground lift
Access: public page. Features state 600 ohms while specifications state 150 ohms for output impedance. Both remain a review issue; no electrical matching calculation uses either value.
