Community Room Audio & Visual Instructions

The easiest way to present is wirelessly with AirPlay from an iPhone, iPad, or Mac — or Miracast from a Windows laptop — using the room’s AirMedia receiver. A wired HDMI option is also available.

Getting Started

Wi-Fi network
NFPL
Wi-Fi password
needhamlibrary
AirMedia A receiver
http://10.1.10.50 · device AM-3100-WF-C4426856F880 (name ends in 880)
AirMedia B receiver
http://10.1.10.80 · device AM-3100-WF-C4426856F8A8 (name ends in 8A8)
Which one?
Use AirMedia A when the room is whole / not split. Use AirMedia B when the divider is closed and you’re presenting in the rear half. Both receivers are on the same Wi-Fi, so technically either is reachable — but the touch-panel routing follows the A = whole-room, B = rear convention.

1. Connect your device to library Wi-Fi

  1. On your phone, tablet, or laptop, open Wi-Fi settings.
  2. Choose the NFPL network.
  3. Enter the password needhamlibrary.

2. Wake the System Control Panel

  1. Find the Crestron System Control Panel on the wall at the front of the room.
  2. Tap the screen to wake it.
  3. Slide the prompt to the right to unlock.
  4. Tap Combine Rooms (use this unless the room divider is closed and you are presenting only in the rear half — then choose Separate Rooms).

First prompt: choose Combine Rooms for whole-room use, or Separate Rooms when the divider is closed.
What to use: if you have an iPhone, iPad, or Mac, jump to AirPlay (recommended). On Windows or Android, use AirMedia. If wireless isn’t working, fall back to HDMI.

Recommended — AirPlay from an iPhone, iPad, or Mac

This is the fastest way to use the room. The Crestron AirMedia receiver shows up as an AirPlay destination on any Apple device that’s on the library Wi-Fi — no cables, no adapters, no Apple TV setup required.

  1. 1On your Apple device, join Wi-Fi NFPL with password needhamlibrary.
  2. 2At the wall, tap the System Control Panel, slide to unlock, then tap Combine Rooms.
  3. 3In the left column, slide up or down and tap AirMedia A. (Use AirMedia B only when the divider is closed and you’re presenting in the rear half.)
  4. 4Tap Projector. The screen resets — tap AirMedia A again to send the signal.
  5. 5On your iPhone or iPad, swipe down from the top-right to open Control Center, then tap Screen Mirroring. (On a Mac, click the Screen Mirroring icon in the menu bar, or open System Settings › Displays.)
  6. 6Select the device whose name ends in 880 (or 8A8 if you tapped AirMedia B).
  7. 7A 4-digit code appears on the projector. Enter it on your device when prompted — that’s it, you’re mirrored.
To stop mirroring: open Control Center again, tap Screen Mirroring, then Stop Mirroring.

  2. On the control panel: Combine Rooms → AirMedia A → Projector → AirMedia A again.
  3. Press ⊞ + K.

  6. To stop: press ⊞ + K and click Disconnect.

Android  Browser

  1. Join Wi-Fi NFPL (password needhamlibrary).
  2. On the control panel, route AirMedia A to the Projector.
  3. Open a browser and visit http://10.1.10.50 (or http://10.1.10.80 if you used AirMedia B).

Fallback — Laptop with HDMI (Wired)

HDMI cables and adapters live in the labeled pouches inside the podium.

  1. 1Plug the HDMI cable into the wall port labeled LAPTOP A (front of room) or LAPTOP B (rear).
  2. 2Plug the other end into your laptop’s HDMI port. If your laptop only has USB-C, use the included USB-C → HDMI adapter.
  3. 3On the control panel, in the left column, tap Laptop A (or Laptop B).
  4. 4Tap the Projector icon to lower and turn on the main screen. Wait a few seconds.
  5. 5The screen returns to inputs — tap Laptop A again to send the signal.
  6. 6Optional: tap Confidence to mirror onto the front side monitor, and/or Room B to mirror onto the rear monitor.
If nothing appears, make sure your laptop’s display is set to Mirror or Duplicate — not extend. On Windows: ⊞ + P. On Mac: System Settings › Displays › Mirror Built-in Display.
Note: when both inputs are connected, HDMI overrides VGA.

Microphones

Both handheld and headset/lavalier microphones are available. Ask staff at the Reference Desk to install fresh rechargeable batteries before your event.

  1. On the control panel, tap to wake and swipe to unlock if needed.
  2. Tap Combine Rooms.
  3. Check the Mic Mute icon in the lower-left corner. If it is red / Mic Mute On, tap it once to turn it off.

Handheld microphone

  • Slide the switch on the body up to turn on.
  • Slide the switch down to turn off.

Headset or lavalier microphone

  • Plug the headset or lavalier cable into the body-pack transmitter (if not already connected).
  • For a lavalier, clip it on your clothing 6–8 inches from your chin, aimed toward your mouth.
  • For a headset, position the boom close to the corner of your mouth.
  • Press the toggle on top of the transmitter to ON. Press it again to turn it off when finished.

Adjusting Volume

Use the ▲ (up) and ▼ (down) volume controls in the lower-right corner of the control panel to set room speaker volume from your connected device.

The Mute Off button (also lower-right) silences the program audio without disconnecting your source.

Apple TV (Room A)

Room A has an Apple TV wired to the Crestron system. Use it to play streaming content from Apple TV apps directly through the projector and speakers — no laptop or phone needed. (For mirroring your own iPhone, iPad, or Mac, use AirPlay instead, which is faster and doesn’t require setting up the Apple TV.)

  1. 1Wake the System Control Panel, slide to unlock, and tap Combine Rooms.
  2. 2In the left column, tap Apple TV.
  3. 3Pick a destination — Projector, Confidence (front side monitor), Room B (rear monitor), or TV Station.
  4. 4Use the on-panel arrow pad, OK, MENU, and Play / Pause buttons as your Apple TV remote.

Room B note: Apple TV is wired into Room A. When the divider is closed and you’re using the rear half on its own, present with AirPlay or Miracast through AirMedia B (device ending 8A8) instead.

Document Camera

  1. On the control panel, choose Document Camera from the left column.
  2. Send it to the Projector (and to Confidence or Room B monitors if you want).
  3. Use the on-panel Power, Lights, Zoom, and Auto Focus controls.

When You’re Done — Shut Down

  1. 1Tap the input you were using on the left column (for example Laptop A or AirMedia A).
  2. 2Tap Clear Route under each destination you used — Projector, Confidence, and/or Room B.
  3. 3Unplug any HDMI cable from your laptop and the wall, and return it to the labeled pouch in the podium.
  4. 4Tap the Power icon in the upper-right corner of the control panel.
  5. 5Tap YES to confirm shut down.
Why “Clear Route” matters

Clearing the routes tells the Crestron system to release the projector and monitors so the next user starts from a clean state. It also makes sure the screen and projector lamp shut down cleanly when you press Power.

Need Help?

If anything on the system doesn’t respond as expected, please ask at the Reference Desk. Staff can reset the system, swap microphone batteries, or help you troubleshoot a connection.

Seeing “The system is in combine mode, please use the control surface at the front of the room”? That’s normal — it means the divider is open and only the front panel is active. Walk to the front of the room to use the main control panel.

About this page. The core procedures (Wi-Fi, Combine Rooms, Laptop A / AirMedia A routing, Windows + K, Apple Screen Mirroring, 4-digit code, microphones, volume, shut-down) come from the vendor’s instruction sheet last updated 3/16/2026. Details for the AirMedia B receiver, the Apple TV, the Document Camera, and the USB-C → HDMI adapter were added from photos of the touch panel and the room. If anything here doesn’t match what you see on the panel, please ask staff at the Reference Desk.
