Focusrite Scarlett 18i20 4th GenHegel H95

Works differently

It connects and passes signal, but not on the terms you assumed.

  • OVERVOLTAGE: amplified speaker-level output into a mic-level input will damage the input stage.
  • OVERVOLTAGE: amplified speaker-level output into a line-level input will damage the input stage.
  • LEVEL/IMPEDANCE: headphone output into a line input — the headphone amp is driving a bridging input instead of the low-impedance load it is designed for, so set its volume control well below maximum and check for level and distortion at the input.
  • OVERVOLTAGE: amplified speaker-level output into a instrument-level input will damage the input stage.
  • DANGER: mismatched signal classes — patching the wrong ports can permanently damage an input stage.
  • UNDECIDABLE — Focusrite Scarlett 18i20 4th Gen USB → Hegel H95 USB-B: missing data (USB (USB host/device role not recorded — connector USB-C does not determine it)). No verdict for this hop until it is sourced.

  • The TCC2 has Dante and the VT4 has AVB, and those are not interoperable without a format converter — the TCC2's analog output is the audio path between these two devices.

  • Channel count limited by physical I/O — verify input/output counts match the design
  • WILL DAMAGE — SOURCE NOTE: the FINNISH section of this same manual (p.10) states that the 8030C may only be connected to a line-level source and never to the speaker terminals of a power or integrated amplifier. The English section of the manual OMITS this. Cited here as the Finnish text specifically, not as a general manufacturer claim: it is manufacturer text, and it is the cleanest published source for the amplified-output-into-powered-monitor damage rule.

  • The Mother-32's 3.5 mm jacks are mostly CV, not audio. Patching a CV output into an audio input is a damaging mistake — this record covers only the rear AUDIO OUT.
  • Moog publishes no output level for the rear AUDIO OUT. Gain cannot be matched from documentation — set it by ear, starting low.

  • Channel count limited by physical I/O — verify input/output counts match the design
  • Balanced Phoenix/Euroblock output into unbalanced RCA input — a nominal +4 dBu pro level feeding a -10 dBV consumer input is roughly 12 dB hot, and the unbalanced leg loses common-mode rejection. Pad the output or set its level to consumer, keep the run short, and watch for ground-loop hum between separately-earthed chassis.

  • AtlasIED FS-D 4"/6" has a speaker-level (amplified) output while Audac M2 exposes only a line-level input — connecting them directly would send amplified voltage into a line input and damage it.
  • DANGER: mismatched signal levels — connecting the wrong ports can permanently damage an input stage.
