Q: Why do I sometimes see a flicker or video-dropout on my second monitor (connected to VB1 HDMI out)?
A: We have found an issue with the Dell USB port on some Dell models. There are two workarounds:
1. Use the USB-A port on the laptop.
2. Use the USB-C port with the VB1 USB 3.1 2m accessory cable (or another USB 3.x certified cable).
The problem doesn't seem to occur when the USB-C port is running at USB 3 speeds.
Q: Can the VB1 camera auto detect the presenter/talker and switch between multiple presenters/talkers?
A: No, we currently do group autoframing. Talker framing may be added in a future later release.
Q: Do autoframing and pan/zoom reset after a meeting has ended?
A: Autoframing always frames the people in the room so it will constantly adjust as needed. The pan and zoom
remain where they were last set.
Q: Does VB1 support 'camera tracking' function: detect which talker is talking and then the camera will focus
on this talker?
A: There are two types of camera autoframing used in the industry today: group and individual. With group
autoframing, the pan, tilt and zoom is adjusted automatically to keep everyone in the frame. With individual
autoframing (or tracking), the pan, tilt, and zoom is automatically adjusted to keep the person talking in the
frame. Individual tracking is most often used in large rooms where it might be difficult to see who is talking
without zooming in. For huddle rooms, individual framing is not needed since it is easy to recognize the talker
because everyone is close to the camera.

Q: Does mute status reset after a meeting has ended?
A: Not independently but it does follow the state requested by the UC app for the new meeting.
Q: Why does the Aux analog audio input have an input level control, but Bluetooth and USB do not?
A: The Aux In is designed to support audio from the front-of-room display. You should use the Aux Input control
in Bose Work Configuration/Management to adjust the level of the incoming display audio until it is at a good
level when the VB1's output level (the one-and-only level control) is at a nominal level.
Bluetooth and USB (PC) levels are synchronized to the VB1s output level which makes it easy to adjust the level
from either source, either on the phone or PC, or via the VB1 remote.
Q: What are the guidelines for setting the Width and Depth in the microphone screen "Configure Room"?
A: First, note that these settings do not affect the VB1 microphone beams, they only change the length of the
virtual mic beams as they appear screen. In other words, changes to these parameters have no effect on the mic
pickup pattern or resulting audio. This feature is just for demo purposes, by adjusting the Width and Depth, you
shorten or lengthen the beams which may look better in your demo.
Q: Does the VB1 support both static and dynamic mic beam steering?
A: Yes. Out of the box it is set to dynamic mode which is suitable for 99% of applications. For some troublesome
rooms, you may want to consider static beams, but only when you know the location of the talkers doesn't
change.
Q: How does the VB1 mic beam steering dynamically track voice of a talker?
A: The beam tracking algorithm is always looking for the most energy in the room and if it determines a location
of high energy is mostly voice content (300Hz to 3kHz) it will allocate a narrow beam to that location.
Q: In the "mic screen" what does the longer beam indicate?
A: The longer beam, or beams, are the active microphone(s). The 5 beams (4 colored beams, 1 roaming beam)
feed into an Automatic Mic Mixer (AMM) and the AMM is always looking for the most active beam(s). When
