Join with the presenter laptop
Connect the computer that will own the room's Zoom audio. Keep this device on reliable power and network access.
Set the room in four passes.
Do not build the whole system at once. Establish a dependable connection, close the audio loop, add the useful views, then check the experience from an online participant's point of view.

Gather the core kit.
Begin with the items that protect participation. Camera angles and extra screens are useful additions; a reliable sound path is the requirement.
Room-ready checklist
0 of 9 readyPass 1 · Secure the connection.
Make sure the venue has adequate Wi-Fi coverage. If it does not, bring a hotspot; a 5G smartphone may be able to provide one.
Add silent clients
Join screen-share laptops, extra display clients, and phones to the same conference. Turn off their microphones and speakers.
Confirm each purpose
Name the job of each device: audio presenter, screen share, main display, second display, room camera, or participant camera.
Why separate devices?
The source guide recommends separate laptops, when available, for the main in-room presentation, additional meeting screens, and presenters who share content.
Pass 2 · Close one audio loop.
Everyone in the room speaks through a microphone. Their voices come from one PA source, and the conferencing laptop captures that mix for people online. Online voices return through the same PA.
Room speakerUses the wireless or fixed microphone.
PA speakerProduces one clear room mix.
Capture micSits close to the PA; the laptop can substitute when necessary.
Online roomReceives the mix through the Zoom presenter.
Route online voices back to the room
Connect the conferencing laptop's audio output to the PA. The source example uses a USB-C adapter with a 3.5 mm connection for PA output and XLR for microphone input.
Do not accept the “I can speak loudly” exception.
A person in the room may be loud enough for local attendees, but people online still depend on the microphone path.
Pass 3 · Add the picture.
Video is secondary, but multiple silent clients can make the meeting easier to follow by showing the featured speaker, the audience, and shared content.
Put the meeting on the main projector
Connect the Zoom presenter laptop by HDMI. Keep HDMI audio off and keep the Zoom screen full-screen.
Share content from a separate client
Use another laptop for PowerPoint, a browser, or another shared presentation when one is available. It joins the meeting with audio off.
Add phone camera views
Old iPhones or Android phones can join over Wi-Fi as cameras. Spotlight or select the useful view for attendees. Apple Macs can also use an iPhone through Continuity Camera.
Add a second display only when useful
A silent Zoom client can drive a second projector through HDMI with no audio.
Optional camera control
The source setup includes an iPhone on a motorized pan-and-tilt mount for a view of participants.
Pass 4 · Verify from online.
Stand beside the room system and it is easy to mistake local volume for online clarity. Verify the experience across the boundary.
Ask an online participant to listen
Speak through each room microphone. Confirm that the remote participant can follow every voice.
Play an online voice into the PA
Confirm that the room can hear the remote participant clearly through the single loudspeaker source.
Inspect every extra client
Confirm that phones, screen-share laptops, and display clients still have audio off.
Check useful views
Make sure the selected camera shows the featured speaker or participants and the shared presentation is legible.
“For our online guests, every in-room speaker must use a microphone. Please wait to be recognized, then use the mic before speaking.”
