Program feeds

Send show audio from your sound desk, switcher, or audio network to the crew, under the intercom.

A program feed is the show audio: the band, the sermon, or your stream mix. Crew hear it quietly under the intercom so they can follow along without leaving their position. When someone talks, program dips so nobody misses a call.

Each feed shows up in the app as its own card that people can turn on or off. Nobody can talk on a feed; it’s listen-only.

What you can use

Anything your Mac sees as an audio input works:

  • Your ATEM’s USB audio
  • A console aux into an audio interface
  • Waves SoundGrid
  • Dante Virtual Soundcard
  • A capture device

The Hub never changes an input’s sample rate, so it can share an input with ProPresenter or OBS.

Add a feed

  1. In the Hub, open Program feeds.
  2. Select Add feed.
  3. Click the name at the top of the card and type a name crew will recognize, like “Program” or “Stream mix”. Press Return.
  4. Under Input, pick the audio device. Each shows how many channels it has.
  5. Under Left / mono channel, pick the channel the audio is on.
  6. If it’s a stereo pair, pick the other channel under Right channel. Otherwise leave it on None (mono).
  7. Make sure the switch at the top right is on.

When audio is coming in, the card shows a level meter. You can also add a feed from the Program feeds card on Overview.

Feeds go to the crew in mono at 64 kbps. If you pick two channels, the card shows Stereo in · mono out · 64 kbps: they’re mixed together.

If you just plugged in an interface and it’s not in the list, select Refresh inputs. If you see No audio inputs found on this Mac., check the device is connected and that the Hub is allowed to use the microphone (System Settings → Privacy & Security → Microphone).

Turn a feed off or remove it

Turn off the switch on its card to stop sending it for now. Select Remove to delete it.

If a feed has a problem

The card shows what’s wrong in place of the meter, like an input that’s unplugged. If the input shows as (not connected), the Hub waits for it. When you plug it back in, the feed comes back on its own.

What crew see

In the app, each feed has a card on the Talk tab with a switch and a meter. In Mix, Quieter when someone talks dips program while crew talk and during pings and calls. See Talk and listen and Your mix.

Set up the Hub

Install the Intercom Hub on a Mac in your booth, link it to your church, and keep it running.

Parties and roles

Set up the channels your crew talk on, who hears what when they join, and which teams get which parties.
