Known Issues

• The optional ARRAY_HEIGHT_OVERRIDE value sent via command strings must be resent upon power cycle
• If the ARRAY_HEIGHT_OVERRIDE command is used to set a height that is outside the valid range (122-914 cm), the command will not display an error but internally, the value will be rejected from being set
• Acoustic reflections from tables can sometimes be mistaken by the MXA920 as another source/talker location. The symptom is a second talker location coordinate set in front of and higher than the actual talker.
  Workaround: Place Coverage Areas to minimize pick-up of table surface reflections
• Channel Names are not set in the initial attempt of ‘push-to-Dante’. Dante interface resets when Device Name is set.
  Workaround: Channel Names are set on the 2nd attempt
• MXA920 LED does not stay on after a reboot if the light settings are set to Unmute = Blue, Mute = Red. Other light combinations work as expected after reboot.
• When a muted dynamic coverage area is moved when a dedicated coverage area has also been established, the mix output of the MXA920 has low-level audio from outside the dedicated coverage area limits.
  Workaround: Unmute and Mute the dynamic coverage area after a dynamic coverage area is moved
