NXDN audio settings for you clever guys!

Hi, i have been reading up in the help files of kpg-111d and i wanted to ask you chaps what settings you use, now as i write this i am unsure what firmware is in the radios (nx-300) so i will have to check, but for example low cut on or off, etc..

Noise suppressor on/off, audio equalizer.

I am all for playing but just thought i would ask.

Thanks in advance Phill, UK.

Couple of things. First any audio profile needs to be the same in all the radios. You can get some really lousy sounding radios with mismatched adjustments, more so than any setting where all radios match.

Second, I shy away from using any AGC (analog or digital). In my opinion it creates more problems than what you think it will solve. For low transmit audio my simple solution is just to have the user speak up. It's got to be a special situation before I enable it.

The rest of the audio shaping parameters are up to you. Everybody has a different opinion on what sounds good to them. I will mention that the lower audio frequencies are where most of the unintelligible non-voice grunge lives so I tend to enhance the treble to try and make a more "crisp" sound. With that said, here is what is in a customers archive that we have done extensive testing to their satisfaction.

RECEIVE
Low cut = checked
Audio gain control = off
Audio equalizer = flat

TRANSMIT
Noise suppressor = checked
Audio gain control = off
Audio equalizer = high boost.

Hi Ramal thank you for your advice, for sure your right with the "get the user to speak in to the mic" bit thats my biggest issue with any radio.

I am going to play this afternoon, i had noted that the audio sounded better through the repeater than simplex and will try your settings soon, many thanks again.

I would agree with ramal's settings and reasoning.

I've had pretty good luck with "flat" on both sides, rather than just the TX side. To my way of thinking, that way you're not boosting the high or the low and it's just the user's natural voice. We've also noticed a difference in radios too. The NX-820's sound better than the NX-800's.

Just remember there is no end all be all setting, you'll need tailor it to specific application. Narrowing the audio pass to the center seems to work better for an industrial environment where background noise is at a high level. I have no problem with that at all. In a quiet office setting a "fuller" sound might be more pleasing to some people.
