The Model C has a USBC port in the center back of the unit, you should also have a “red” colored USB cable that you can use to connect to you computer. The Model C can connect to either a USBC port, or on older computers, a USBA port.
Once you have connected your Model C, your computer should recognize all the ports, 4 USBA ports on the front, 1 USBA port on the rear, and a USBC port on the rear. Your computer should see all of these ports as well as the SD card and audio features. To use the Audio device, you must select USB Audio, from your audio selection menu from your Operating System audio menu.
Buttons on the top of your Model C are self explanatory, the upper right is Volume up/down, the lower right is speaker mute. The lower left is your onboard microphone mute button and the upper left is your system mute button which will mute the operating system sound.
Lights can be turned on/off by pressing the top left button, which turns off the Model C lights. You can also use the switch on the rear to turn off the top glass light if you just want the Model C light bar to show.
The Model C can be used as a standalone amplifier without needed to connect to a computer. The Model C has a 20 watt onboard amplifier that connects to the stero speakers so it can be used to amplify and audio signal. The rear and front audio jacks can take any audio signal in and the Model C will amplify the audio. A common use would be to connect the Smart Desk Boom woofer and connect it to the rear audio jack, and connect a audio signal (Example from an Xbox) to the front audio port, to amplify and have high quality rich sound.
To power the amplifier, you can connect any USB power brick to either rear facing USBC port. To have a portable amplifier, you can power the Model C with a USB power brick and connect a headset to the front audio in jack. We use the Model C for a portable amplifier for our presentations.

The Model C, can be used as a zoom speaker phone that can be moved into the center of you office, to act as a traditional conference speaker phone. (Example: Polycom speaker phone). The onboard mic is amplified, so you will probably want to adjust volume and filtering levels on your zoom interface, as the amplified mic means you can be anywhere in the room and it will pickup voices and room noise. It’s a great solution for having conversations with multiple people in a room.
