The symptoms you described suggest that there may be several possible issues with your Kustom Bluetooth PA speaker. Here are some steps to diagnose the problem:
Check the battery: Ensure that the battery is fully charged or replace it with a new one if needed. If the battery is old or worn out, it may not provide enough power to the speaker, causing the crackling sound.
Check the connections: Make sure that all cables and connections are properly plugged in and secured. Loose connections can cause crackling sounds or no sound at all.
Check the volume: Turn up the volume on both the speaker and the device connected to it (such as a phone or tablet) to see if that resolves the issue. If the volume is too low, it may result in no sound or faint sound.
Test the mic and instrument input: Try connecting a different microphone or instrument to the speaker to see if the problem is with the original mic or instrument. If the new mic or instrument works, then the issue is likely with the original device.
Check the speaker components: If none of the above steps work, there may be an issue with the speaker's components. It's best to bring the speaker to a professional technician or authorized service center for repair.
Hopefully, one of these steps will help you diagnose and resolve the issue with your Kustom Bluetooth PA speaker.
The Pre Out and PWR In for a method to insert an effects loop. The output signal from the Pre Out should be line level so you would not connect this to our microphone input on the PA, but preferably to a Line Level input otherwise you would overdrive the PA's input. When you connect the Pre Out, the 1/4" jack may interrupt the signal so you may lose output to the Champion's amplifier/speaker. If this happens, you need to have a return line with the same line level signal plugged into the AMP In to get your sound back on the amplifier itself.
Well, I would say it isn't dropping the level of "the whole pa", it is just dropping the level of the input you have plugged the fx into. Check the settings on your fx unit, there are usually input, output and mix controls that are independant of "the pa" and affect the amplitude of the signal going into your mixer from the fx unit.
It can plug into a guitar amp or PA system both. If you use an amp, you could hear yourself alone through that, then output jack "power amp out" to PA or put a mic in front of it from the PA. If you don't use an amp, it can plug into the PA but, you would only hear the 8 pieces together and have no way to hear yourself seperately.
It is unlikely to find a compatible USB convertor for that digital recorder. If it has audio input you can probably use a similar cable to that for the IPOD described next. For the IPOD, get a 1/8 inch STEREO splitter cable that splits to 1/4 inch plugs or RCA plugs to connect to the PA system. Radio Shack will probably have a suitable one.
Connection all depends on what type PA system you have. Here are the rules: Power this device from the SAME receptacle your mixer is powered by, even if it means running an extension cord. Use ONLY a balanced line from the mixer... either TRS cable or XLR cable.
There are a number of configurations for a mixer like the 1832, the most common are PA system and Recording system.
There are Main output jacks which carry the mix as summed in the main faders. These in a PA system would feed the pa amplifiers which drive the house speaker system for the audience. These connectors are XLR 3 pin type on the rear, intended for professional pa amplifiers which use balanced +4dbv line input level. Amplifier which have 3 pin XLR connectors for input signals can accept that high level signal. For home style HiFi amplifiers, the signal level is nominally -10DBv and balanced or unbalanced signal lines with 1/4in diameter phone plugs which are connected to the mixer by way of a second set of Main output connectors which are 1/4in phone jacks. Use whichever amplifier input level your amp has.
If you are not using it as a main PA house mixer, but using it for recording, the main output connectors go to a 2 channel recorder or computer sound card recorder.
The power amp and your monitor speakers are connected to the connectors labeled "Control Room" (CTRL Rm). These output are useful for recording because the signal through the mixer can be monitored from several buses, Solo, main mix, selected by buttons provided. The buttons only affect the signal heard through the control room monitors, and not the main output which only sees the main mix so selecting "solo" does not interrupt the signal going to the recorder while the engineer in the control can be checking other signal paths through the board.
