AV SIGNAL FLOW · 系統図

Wiring you can write.

Describe connections port to port and get SVG. It does more than draw: it flags the cable that seats perfectly and carries nothing before anyone reaches site.

WHAT IT CATCHES

It fits. It does nothing.

The faults worth catching are the ones where the plug seats, the drawing looks right, and no signal arrives. Every verdict carries its reason, and the reason follows through into the cable schedule.

warning ext.CAT → netsw.1HDBaseT uses Cat cable and RJ45 but is not Ethernet. It does not go into a switch

warning cam.SDI → sync.REFThey only share BNC. A reference input will not lock to video

warning cdp.ANALOG → dac.DIGITALThey only share RCA. Analogue audio into a S/PDIF input produces nothing

warning pc.HDMI → mon.DVINeeds an HDMI-DVI cable. Declare it with via and it lands on the parts list

warning desk.MAIN → amp.LINEBalanced to unbalanced: level drop and hum-loop exposure

HOW IT READS

What you write is what comes out.

Every diagram below was compiled at build time by the published package from the source beside it.

Ports and ranges

CH[1..16] expands to sixteen. Declaration order is drawn, so IN 1 never ends up below IN 2.

ports.khmclean

device mixer "Yamaha DM3" as mixer {
  in  CH[1..16] : xlr
  out L, R      : xlr
  io  DANTE     : dante
}
device amp "アンプ" as amplifier { in IN_L, IN_R : trs }

mixer.(L, R) -> amp.(IN_L, IN_R) : trs 3m "A-10"

output

Wireless

A radio path is not a cable, so it carries a frequency where a cable carries a length. Wire it straight into the desk with no receiver and you get told.

wireless.khmclean

device mic "ワイヤレスマイク" as microphone { out RF : uhf }
device rx  "受信機"           as interface  {
  in  RF  : uhf
  out CH1 : xlr
}
device desk "卓" as mixer { in CH1 : xlr }

mic.RF -> rx.RF     : uhf [ch=38]

Equipment libraries

A desk's sixteen channels do not get rewritten per drawing. Define it once with model, instantiate as many as you like with device … from.

  out L, R      : xlr
