How do i hook up a reverb/delay peddle to a mixer

Why are you not using the inserts? Either assign a sub channel to your effects unit or do it at a channel level. In either case using the insert.

It sounds like you're new to 'professional' mixers. You would NEVER normally use an aux for effects. Any effects will normally be inserted in the sound chain using an insert. You have a pair of group inserts if you are wanting to apply an effect to the output (these are after the mix) and would typically be used for master de-essers or possibly compressor limiters or maybe even an equaliser, it would not be sensible to use an effect like a delay/reverb here.

I would have expected you to be using the group outs for the monitor mixes and am not sure what you may be using them for otherwise. If you used these you would free up 4 of the Aux outs for a 'multi channel' reverb/echos which you could take back into other channels and back into the main mix.

What is it you are tyring to achieve?

Can't find a manual but can still explain. Delays, chorus, flangers, and reverbs are all the same effect except the different names of them will allow you different adjustments. Chorus usually has a width control which controls pitch shifting. Flangers and delays will have a feedback control which simply means, how many times you hear the echo. On reverb units, room size means how long of echo(even though it;s short) you want. Delay is the same with much longer echo, feedback is the same as on flangers except the flangers time is very short meaning the effect is at almost the exact time resulting in feedback causing a metalic sound. I probaly just confused you but good digital delays usually have all the features and will usually do all 4 effects depending on how you set them. If you want delay, set width on 0 and adjust time and feedback. For flanging, adjust width and speed and feedback. Chorusing, adjust time, width, and speed. Reverb, adjust time, set width on 0, and feedback. I see it has a level(mixture, how much effect you hear), and a replay(feedback, how many times you hear it), and a delay knob,(how long the echo will be) The range/mode switch allows for settings of diferent time lengths and INF setting allows for infinite repeat. Hope this helps.

Make sure you are using BALANCED interconnection cables to the speakers, either XLR or TRS connections. ALSO make sure all interconnected equipment such as the speakers AND the mixer are powered from the SAME receptacle at the venue... yes you have to run extension cords... the pro's do it so they don't have hum and other noise and don't damage their equipment.

You will need to buy an effects unit for this, either delay or reverb depending on the echo you want, there are no built-in effects on this mixer, sorry!

Hope this helps!

The problem is that card has only UNBALANCED inputs. You really need balanced or first run the mixer outputs through a DI backwards. Frankly, I would recommend NOT using a card within the PC as there is so much digital noise. Use either a USB or Firewire external convertor and for goodness sakes use balanced lines from teh Mackie... ALL interconnected equipment needs to be powered from the same receptacle or source. M Audio, Roland/Cakewalk and Presonus all make cards as do others.

Sorry, from the signal flow diagram there is no easy way to do this. You could have a seperate reverb for each channel as an insert, OR pick off the aux outputs into a reverb unit snd run them back into the stereo returns... The effects on phones will also be on the mains and will NOT be present when SOLO is selected.

Troubleshooting is always a "process of elimination." Have you tried hooking up your Peavey powered mixer to another set of speakers? How about connecting the speakers to another audio system? Your term "very little sound" could mean audio input problems, mixer/amp settings or failure and possibly speaker damage (internal passive crossovers). Please be more specific.

Usually delay is associated with "reverb" not echo. If you are in a large room, the room acoustics can add reverb without the benefit of signal processing.

Reverb NORMALLY passes the inout signal as is and then adds in a delayed version on top.

The delay should be less than the room size delay.

Try turning off all effects as a start. There is some "transport" time if it goes through a digital signal processing.
