Post CYBERMAXFM+ 25watt stereo transmitter w/ DSP and RDS problem Reply with quote
I purchased a CYBERMAXFM+ 25W FM stereo transmitter with DSP and RDS a few months ago, when i got it i only tested the output power but never really tested the audio and i shelfed the unit for a few months. i finally installed it today and noticed it has no has no left audio channel input, only the right audio channel works, i checked all the jumper settings inside the unit, pre-emphasis in the stereo encoder and in the exciter and all were in the correct position. (none in the exciter and 75 in the stereo encoder) power output, RDS encoder, MPX in/out and 19khz out work fine... the only problem is that there is no left audio channel input. also tried to change the audio cables tried the XLR inputs and checked every possible thing that might be wrong and its still the same. so im thinking it could be the SE5000DSP stereo encoder with the problem, probably with a loose solder somewhere or a busted part. what else can i check cause i really have to get this working by the end of the month. Pray

It is possible that you've burned one of the input balanced op-amps.

I've sent you some ideas to look at via email.
