How to fix Polycom Vortex EF2280 when no microphones are gating?
- P
  Peter FryAug 12, 2025
  If no microphones are gating on your Polycom Conference System, here are some things to check: * Ensure the microphones are not muted. * Verify if the microphones are part of one of the two automixers and assigned to an automixer. * Check the microphone levels. * Confirm phantom power is enabled where needed. * Adjust the Hold Time, as it may be too low. * Review the Gating settings and Gating Priority. * Examine the Maximum Number of Open Microphones. * Adjust the Gate Ratio if the Gate Threshold is set to Adaptive, or adjust the Manual Threshold if the Gate Threshold is set to Manual. * Check if Chairman Mode is enabled.

  If too many microphones are gating on your Polycom Conference System, consider the following: * The Hold Time might be too high. * Assign a Chairman Mic. * Set Gating Priority so that not all microphones have the same priority. * Adjust the Gate Ratio if the Gate Threshold is set to Adaptive or adjust the Manual Threshold if the Gate Threshold is set to Manual. * Using the Adaptive Gate Threshold is recommended for more accurate gating.

Why is there excessive room gain in my Polycom Vortex EF2280 Conference System?
- L
  Lisa SimmonsAug 20, 2025
  Excessive room gain in your Polycom Conference System can be due to several factors: * **Excessive remote (reference) input amplification:** Apply enough gain to the codec, phone, or program audio inputs which will make up the Reference input signal. * **Excessive microphone amplification:** Select proper microphones for talker distance according to pickup pattern and directionality, and properly calibrate mic inputs. * **Excessive coupling between loudspeaker audio and microphones:** Reduce mic coupling by repositioning mics or loudspeakers, or by reducing loudspeaker amplification.
