Sub group 4 went out

During a show, sub group 4 suddenly stopped working. By that, I mean there was no output from the group. I switched all the drum channels (my group 4) back to L-R and centered the channels and I was back in business. After the show, I tried a number of channels and all had the same symptoms, no output when using sub-group 4. Anyone have ideas on where to start diagnosing the situation?

Send a signal thru the sub 4 insert and see if it comes out the sub 4 output. You may have jarred a ribbon cable loose in transport.

No output to main speakers.


I presume you mean there is no output on the main out. Is there output on the groups etc? Have you checked all the routings? What else works / doesn't work?

I want/need to restore my new PreSonus 24.4.2 digital mixing desk back to factory default settings, but how ? I some how lost audio sound from all my sub groups when attempting to add effects (reverb) to...


From page 84 of your user manual, the signal flow diagram shows that the two effects busses can be sent to the sub busses. You CANNOT send the subs through the effects unit since that would loop... so the effects that are selected from the channels onto the two FX busses which are then processed into the effects signals, then can be ADDED into the sub group signals. Make sure the subs are NOT selected to the mains and the solo of the subs is not set Nor is the sub mutes. You say the subs are showing signal... MAKE SURE THIS IS with the indicators set to display "Output" as that is the one that counts.. If the output when the sub is selected shows no signal, then likely the mute for the sub has gotten set.

The sub woofer wire inside came off my Simmons DA200S. where do i plug it back in?


If you look on the circuit board that the big black heat sink is attached to, there are two output amp chips (integrated circuits) attached to it. IC7 is the sub output amp. Next to that is a white jack with two pins sticking out, labeled J9. J9 is where you plug your sub into.

I have a A&H GL2400 - 32 ch.Console; How do i hook up (5) Effect units to the Console?


Is this for live sound? You can use your aux outputs as sends if you're not using them for monitors and return to spare channels. If any units are being used for only one channel, either run them in-line (use the effect unit's wet/dry settings) or use the channel's direct out and return to a spare channel.

If one effect is applied to several channels you could put those into a sub group, take that sub output to the unit and return the 100% wet mix to a spare channel.

Be careful not to send the return channels back to any auxiliaries you're using for effects.

No sound


There can be any number of reasons for this problem - solve it diagnostically by starting with something that you know is working and work through systematically to the other end.
  1. Test a microphone on a separate amp to make sure it works okay. Check amp and speakers working. Check that all output cables from mixer to amp are working by testing separately.
  2. Plug microphone into a channel on mixer. Also plug in headphones and turn headphone volume control up.
  3. Make sure input sensitivity knob is turned up a bit (say half way) and main output faders (yellow) are up.
  4. Check that channel is turned on (little button just above the channel fader- needs to be pressed down)
  5. press pfl (pre-fade listen) button (next to button to switch channel on)- do you get any sound on main output or headphones or any indicator lights on mixer to show signal is getting that far (eitehr the individual channel metering lights or the main ones in the central section)?
  6. turn off pfl - make sure channel fader (slider) is up - normal position is ) - about 3/4 of way up. Check lights again on individual channel and main output section - any signs?
  7. Is the sub mix button for the channel pressed down - in which case you will need to bring sub mix (red) output faders up as well as main faders.
  8. If you have got signs of signal on the individual channel but not main see if the channel has been routed somewhere odd (like a subgroup of channels).
  9. Plug a working amp and speakers into one of the auxiliary outputs and use the relevant auxiliary send knob (on each channel just above the faders and pfl switches) to pan some signal to that auxiliary out - do you get anything? There is also a headphone socket for listening to the auxiliary channels (with a selector switch /knob to determine which one - make sure it is in the right position) try listening to the auxiliary output with headphones - anything? If yes the problem lies in the main output section.
  10. Check that there is not a jack plug in the insert socket (to route signal through an external effects unit) without a matching return jack being plugged in - if appropriate is relevant effects unit switched on and correctly set up - if unsure remove the insert plug to take it out of the system.
  11. Make sure any mute buttons are not switched in on main outputs.

I am experiencing signal loss at numerous points on my mixer. I have heard stories about ribbon connectors coming loose as the things age. Is it possible I can reseat connections inside to solve this?


You need to describe what you mean by "several points".

These mixers have sections grouped and if you lose signal as a group, I believe it is eight channels, cables MIGHT be a problem. If it is random channels, it is more likely a failure of faders if they seem noisy and cut out. A small amount of CRC226 squirted into the center of the slot and working them MIGHT restore noise free operation.

Note: One can do a lot of troubleshooting externally by analyzing the different outputs from the AUX and SUB's and headphones using the SOLO buttons, etc. First thing is to completely characterize the failures.

My PMP 3000 is a dead stick. Help? We were playing a gig and everything was sounding amazing, all of a sudden the volume on channel 2 (a Wireless Digital Reference Head Mounted Mic, gotta love drummers)...


Please note that the outputs of the MAIN L/R line outs are TRS balanced. If you plug mono plugs into these or connect to mono device you MAY have a problem of grounding out half of the drive internally. ALSO please read my tip on here regarding a polarity hazard of speaker cables of PMP amps if you do NOT have Speakon to Speakon cables, but have Speakon to 1/4 inch cables.

Likely one of the power amps in this has failed If no lights come on the unit now, then the power supply is wiped out as well. It takes about $50 worth of parts and quite a bit of skill and work to restore the unit, including carving out burned board and re-insulating. Likely a feedback occured on that mic and started the whole thing. Supersonic feedback is something most musicians are NOT aware of, but if the feedback is above the range of hearing, the amps can be strained as they may go to maximum power trying to amplify the sound you can;;t even hear. Piezo tweeters are capable of frequencies up to 30KHz.

If this is under warranty exercise it immediately.

When bounce tracks on my micro-br there seems static going on


First of all, it would be better for you to pan the tracks, and bounce into 2 tracks for stereo separation.

Your "static" may stem from three pausible causes.

One, four tracks into mono may make your output a little muddy.

Two, watch the reverb - if you keep applying reverb after each bounce, it starts to sound bad.

Three, if you have drums/rhythm, turn it off while bouncing. Only have drums on when mastering, because they will keep getting re-recorded during bouncing.
