Audio

CastPad gives you the mixer two ways: a compact Audio card on the Switcher page for a quick level grab, and a full Audio page in the navigation when you want every channel in front of you. CastPad reads each input’s real capabilities from your switcher, so the controls you see match what that channel can actually do — no dead buttons.

Faders

Each channel is a fader strip — vertical or horizontal depending on the layout. Drag to set the level anywhere from −60 dB up to +10 dB. Pull the fader fully down to mute (−∞).

  • 0 dB magnet — the fader snaps to unity as it passes 0 dB, so you can find the reference level by feel.
  • dB pop-up — long-press the fader to open a precise editor with ±0.2 dB stepping and numeric entry, for when you need an exact number instead of a drag.

ON and AFV

Two buttons per channel govern whether it’s in the mix:

  • ON / OFF — the per-channel mute. ON puts the channel in the program mix; OFF silences it.
  • AFV (audio-follow-video) — the channel’s level follows its source on air, so audio comes up when the picture does. On the master, AFV means follow Fade-to-Black — the master ducks with FTB.

Buttons appear only when the channel supports them, so you never tap a control that does nothing.

Meters

Every fader paints live stereo L/R level meters right inside the strip, so you watch the signal where you set it. Channels that are out of the mix (both ON and AFV off) are desaturated, making it obvious at a glance which sources are actually feeding program.

Channels

Channels are auto-labeled by input type — MIC, XLR, TRS, RCA, AES, MADI, MP (media player) and cameras — and duplicates are auto-numbered. External analog inputs come first. A master fader with its own AFV sits with the rest, controlling the overall program level.

Safety

  • Fader lock — each channel has a lock: tap to lock, long-press to unlock. A locked fader can’t be nudged by accident mid-show. Haptics confirm the lock.
  • Configurable cards — on the Switcher page the gear menu picks which two channels an Audio card shows. Each slot can point at a specific input, or at Master, or at Auto (priority) — which picks the first external input it finds in the order TRS → XLR → MIC → RCA. A Switcher Audio card defaults to Auto + Master. Add more cards as you like; each one remembers its pair.
