Re: intermittant LR output problems Main outputs (XLR
Intermittent problems cn be a real pain to find... BUT I want you to verify your use of the mixer and its connections as one can cause the output drivers to latch up due to ground bounce.
Make sure your outputs go to the power amps AND into balanced inout at the amps... either XLR or TRS connectors.
Make sure that the amps are POWERED from the same receptacle as the mixer... even if you have to run power back to the mixer. If you power the mixer from a different receptacle at the other end of the room, ground bounce of the safety ground MAY exceed the common mode drive of the mixer and cause the output drivers to latch up or even be destroyed!!!

You don't mention the make and models of the gear you're asking about, so we can't address your pacifist setup. However, most mixer outputs are going to be at line level, whereas a guitar amp inputs are instrument level. Line level is way hotter than a guitar amp can handle. You need to find a mixer that has a -10dB output to do what you're asking.
Make sure you are using BALANCED cables from this... eithe XLR or TRS cables. Using TS unbalnced cables MAY ground out the signal which is sent as balanced. Here is a schematic for the 24 channel unit... yours just has eight more channels. http://elektrotanya.com/behringer_ub2442fx-pro_sm.pdf/download.html

By looking at the signal paths, you can OFTEN do a lot of testing from the available jacks. If the contacts on the right main INSERT jack go bad, that would cause your problem,,, NEVER use other than an insert cable in these jacks.
You need to connect the speakers using an XLR cable into the Main output jack on the back of the mixer. If they are powered speakers you will need to connect them into a power source and turn them on AFTER connecting them. Once powered on you can control the signal going to the mixer with the Main Mix fader.
Personally I would run the RCA outputs to the RCA in on the APS. If you insist on using XLR from the APS to the board (like through a snake etc) I would higly recommend using XLR to 1/4" adapters. These things have wonderful little transformers in them (yes, wire wound transformers) that do the 1/4" to XLR conversion really nicely so that you can run your signal through the snake or just so that you don't get the hum and distortion that can be associated with unbalanced signal transfer. You want a HI-Z unbalanced to LO-Z balanced adapter. Not always easy to find, but if you absolutely cannot locate any, I have a couple in stock. I suggest you look around though, because mine aren't cheap!
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.
just use the main left and right outputs of the behringer to run xlr (3 prong balanced) to 1/4 inch (looks like a big headphone plug) cables into the inputs of the crown amp. the mixer has the xlr outputs and the amp has 1/4 inch inputrs, sop the cables will have to reflect that on both ends. run the outputs of the amp (rca outputs, i believe, you may have to get a rca plug to 1/4 inch jack adapter, and then use a 1/4 inch speaker cable) to the inputs of the speakers, again, the amp has rca outputs and the speakers will likely have 1/4 inputs, so you will have to address that wil an adapter. have each speaker in its own channel.
