I am looking for opinions or experience in XTS5000 program settings for Automatic Gain Control choices (Radio Wide, Tx Audio Control Per Mode). It appears as though there are settings for the Internal and External Mic with Analog, Digital, and Securenet choices, plus an overall AGC, a Digital/Analog Balance and then Noise Suppression with Standard and Advanced options.
Recent recommendation from the manufacturer is to enable AGC on Analog, Digital, and Securenet choices, with the values set at the "0" default because the system has Digitac and/or AstroTac Comparators already built in.
I understand that AGC is a volume issue, and Noise Suppression is a clarity issue: two distinct items.
Fire users following analog versus digital tests conducted in Orlando to compare audio quality of voice transmissions from an active fireground are inquiring about Noise Suppression. The internal CPS Help file indicates that Noise Suppression works best when the AGC fields are disabled, and when disabled, the Digital/Analog Balance field be enabled to reduce acoustical feedback.
The Standard Attenuation Level provides a "moderate amount of noise reduction to transmitted audio," and "should be used in areas where there is a reasonable level of background noise." The Advanced level provides a higher level of noise reduction, and be used in areas of high level of background noise. There is also an important note warning that this setting may also cause some degradation of audio when no background noise exists.
Seems to me like there are a lot of competing features here, all trying to do the similar things, but fighting each other in the process. I can't program some radios as "fireground radios" and "moderate noise radios" and "good condition only" radios unless I can ensure they are only used in those environments which is unlikely.
Does anyone have a "happy medium" setting recommendation, or opinion as to which is more important, AGC or Noise Suppression if I have to choose between the two, along with any data to support or justify that choice?
Thank you for any assistance you can offer.
