ClassInTheBox – FAQ´s
1. Minimum requirements
ClassInTheBox includes a USB Type-C cable to connect it to the computer. The computer to which citb is connected needs to have at least 1 USB 2.0 port (3.0 recommended).

Mac OS X
Compatible with Mac OS x Tiger (10.4) and higher.

ClassInTheBox LMS and videoconferencing platforms
ClassInTheBox is only compatible with the BROWSER VERSIONS of the different videoconferencing platforms: Meet, Zoom, Teams, Skype, etc… ClassInTheBox is NOT COMPATIBLE with the DESKTOP APPLICATIONS of these platforms. You must ALWAYS use the WEB VERSION.
To see how to set up citb on the different platforms, see the First steps page.
2. Operating system (OS) configuration
When you connect ClassInTheBox to your computer, we recommend setting citb as the system’s default audio input. This way, once you start any video conferencing platform, citb will be the default active microphone.
In cases where you need audio to be output through an audio system or speakers, connect them to the ClassInTheBox mini jack output and set citb as the default audio output in the operating system. If you don’t need it that way, set the audio output through your computer’s speakers / headphones.
Connection to the computer
When you connect ClassInTheBox to the computer, the green LED should light up. This means that it is active. If this does not happen:
1. Check the power supply of the computer.
2. Check that the connection with the USB C cable is correct.
3. Check that the USB C cable is not defective. If you have another cable, try it as well.
Wireless microphone charging
For correct operation of the system, the wireless microphone must be sufficiently charged:
1. Connect citb to the switched-on computer, and in turn the microphone to the device via the front USB port.
2. Press the citb switch button. The red LED lights up. The charging of the microphone is in progress.
3. The red LED indicates that the microphone is charging. The green LED indicates that charging is complete. With the microphone fully charged, you will have an autonomy of 7 hours.
Microphone and citb pairing
ClassInTheBox is paired by default with the supplied wireless microphone. To check for proper communication between them, follow the steps below in the order given:
1. After checking that the microphone is charged, turn it on by pressing the power button for 3 seconds. The blue LED will start flashing looking for the connection with citb.
2. Connect ClassInTheBox to the computer with the USB C cable. The green LED will light up.
3. Once the microphone and citb are connected, the blue LED on the microphone will be steady. This means that the pairing has been successful.
Basic solution to pairing problems
If the microphone fails to pair with the device, the blue LED will remain flashing. Until it is correctly paired, it will not work. To establish a connection (blue LED stays on steady), follow the following sequence of steps:
1. Switch off the wireless microphone by pressing the power button for 3 seconds. The blue LED will turn off.
2. Disconnect ClassInTheBox from the computer.
3. Turn the microphone back on. The blue LED will flash.
4. Reconnect ClassInTheBox to the computer.
5. Check that the blue LED on the microphone is steady. Until this happens, pairing has not taken place.
Forcing pairing manually
If the microphone fails to pair with the device using the basic procedure, you will need to manually force the microphone to pair:
1. Disconnect ClassInTheBox to the computer.
2. Turn on the microphone by pressing the power button for 3 seconds.
3. Now, press and hold the MUTE button for another 3 seconds. The blue LED will flash faster looking for a connection to citb.
4. Connect citb to the computer. Once the connection is established, the blue LED on the microphone will be steady.
4. Fusion mode and Show mode configuration
To use ClassInTheBox, in Fusion Mode or Show Mode, i.e. to output your voice from citb through an audio system or speakers, you must configure it in the following way depending on the operating system you are using. You can see what both modes consist of in the citb section.
