Re: [Repeater-Builder] Audio Limit with GE MAstr Pro
Thanks John. Some of my users sound great on the system, then some users are distorted. I can talk with them on other repeaters and they sound fine there, just on this one they sound bad.

Re: [Repeater-Builder] Audio Limit with GE MAstr Pro
Matthew, You shouldn't need to reduce the audio level going into the controller. The RX audio level adjust pot on the controller should allow you to adjust that level as low as you need. You might want to go through the procedure for setting audio levels (RX and TX) in the controller manual again. Is the clipping occurring in the repeater receiver or transmitter? Assuming you have a local speaker on the MASTR Pro receiver, do you hear the clipping there? DTMF falsing could be caused by a number of things. First make sure you set the RX audio level using the procedure in the controller manual. I don't have a MASTR Pro manual handy at the moment, and can't remember whether deemphasis is done before or after the volume control. If deemphasis is after that point, you need to make sure you deemphasize your audio. The CAT controller may provide this option... if not, you'll need to do it yourself going into the controller. There is information on deemphasis, including recommended circuits on repeater-builder.com. If you need additional reduction of high frequency audio response, you might try a capacitor to ground from the high side of the volume control. Start with .01 uF and experiment up or down from there. More capacitance will roll off the highs more. This will reduce the overall audio level into the controller somewhat, so be prepared to re-adjust your controller audio levels after you get the frequency response you desire.

[Repeater-Builder] Audio Limit with GE MAstr Pro
With audio coming from my GE MAster Pro from the high side of the volume control, is there anything that can be done at that point to limit the amount of audio coming into the controller, as well as making the audio give a little more base response as opposed to a high tone pitch? Still having the problem with some of the users clipping the repeater on the high end, as well as now some of them are hitting the falsing dtmf signal. The controller is the Cat 1000B controller.
