This general design guideline is no different than a typical installation where the designer will try to optimize gain before feedback. Ceiling Microphones While commonly used, ceiling mics are problematic for the following reasons: They present the worst conditions for acoustic coupling between the microphone and the speaker, as both may be physically mounted in the same surface. ERL values will very likely be positive since acoustic echo loss between the loudspeaker and microphone is minimal - the mics are very close to the speakers. Poor gain before feedback due to low voice volume relative to ambient room noise - due to distance from the mic. Poor voice pickup due to low voice volume relative to ambient room noise - due to distance from the mic.

Pakedge Device and Software. Tyler Truss Systems Inc. Aec-2h generally recommend restricting the range of the user-level control to ensure that no major level changes will affect the AEC algorithm performance.
The direct sound line of sight from the speaker is picked up by the Near End microphone and sent back to the Far End. Settings in the ms to ms range are common. Based upon this model, an adaptive filter is created and continuously updated. Level dB In This allows digital gain adjustment after the mic pre-amp to fine tune the input level.
Refer to eBay Return policy for more details. External muting If muting is done at the microphone, a minimum threshold value will have to be set in the Advance parameters dialog box of each microphone input, such that any input signal below the set threshold value will freeze the AEC algorithm adaptive filter settings in their last state. Muting of a microphone could be done of two ways, internally via contact closures on a Logic Box, control processor, etc.
Once operational, make level changes as required but do not change the volume of the amplifier. Rooms that already yield poor intelligibility make for terrible conferencing rooms. Hitachi Denshi America, Ltd.
