Connecting to the System in Smart Rooms
Using Crestron Panels
If the touch panel is unresponsive, missing the room number, or has an inaccurate time, try restarting the processor by using a pen or other narrow object to press the hardware reset button (HW-R) on the front. Note that the complete reset can take upwards of two minutes. Please call the Solutions Center at 389-6449 or email AVTroubleshooting@coloradocollege.edu if the panel is still unresponsive.
You can play audio without turning on the projector by pressing the AUX AUDIO button and connecting your device via the 3.5mm headphone connection at the rack.
For rooms that have an Apple TV or Air Media, look on the display screen (TV or projection) for connection information.
All smart classrooms will have HDMI or VGA connections (both in most cases), and are also equipped with Thunderbolt to HDMI and USB-C to HDMI adapters. To connect your computer, be sure you have selected the appropriate input (HDMI or VGA) on the control panel. If you do not see your image displayed, check that all connections are tight, try re-seating the cables and any adapters. It takes a few moments to establish a connection, so please be patient. If using a PC, press Windows-P and ensure that you are not set to display "PC Screen Only". If these steps fail to correct the problem, please call the Solutions Center at 389-6449.
The wall remote will turn on and off the TV or projector, adjust volume, and select the input source according to your needs. Rooms with a wall remote that have built-in video equipment (Blu-Ray, VHS, etc.) will still have remote controls for the players, but the TV or projector will not have a separate remote.
If you have requested a microphone for the block, you'll have the option of using a lavalier mic (clip on) or handheld. The mics share the same frequency, so you can only use one at a time- be sure that only the mic you use is switched on. On the touch panel you'll see volume controls for mic, source, and master. You can adjust the mic and source (Blu-Ray, HDMI, etc.) levels independently- master raises the output of everything. Proximity to the mic is also important, especially if you are masked. When using the lavalier, you'll likely want to clip it to the front of your mask as the standard method of clipping it to your collar won't be sufficient to amplify your voice. The handheld mic needs to be held close to your mouth, in a direct line (known as on axis). If you are too far from the mic, or not speaking directly into it, you won't get the added volume you need.
AirMedia is a cross-platform wireless communication protocol, allowing Mac and PC computers to wirelessly connect to the room display. When selecting AirMedia on the control device, an IP address and login code will be displayed on the lower left of the display. If you do not have the AirMedia client installed, enter the IP address in your browser-you will be prompted to download the appropriate version for the device you are using. Enter the IP address and code into the client to display your presentation.
Troubleshooting tip: If you experience intermittent, brief audio dropouts, connect your laptop to the network via ethernet cable and turn off your Wi-Fi. There is a courtesy network port at the front of the equipment rack, and likely a few others located on the wall.
Normally, when connecting your computer via HDMI, audio will automatically be routed to the system. In the event it is not, however, follow the steps outlined below.
Connecting PC audio
When you hover your mouse over the speaker icon, audio routing will be indicated. It should reflect your connected HDMI destination, i.e. Crestron, projector or TV model number, etc. If it shows the built-in speakers (Speakers / Headphones), right-click the speaker icon and open Sounds. Select the display device, and Set Default.
Connecting Mac audio
Hover over the volume icon at the top of the screen and select the Output (to) Device. If you do not see the icon, open the system preferences and select Sound. Choose the output tab and select the HDMI destination.
