How to Set up Auxiliaries on a Mixer.


Here are some tips to set up the auxiliaries properly on your mixer:
  • Step1:
Your auxiliaries allow you to send the signal from a channel strip to somewhere else while maintaining the signal on the channel strip. For instance, you can use auxiliaries for monitor mixes for performers in a live environment. You can also use auxiliaries for external effects processors or a number of different situations.
  • Step2:
Set the auxiliaries to pre-fader to allow you to change the level for the auxiliary with the auxiliary knob but not with the channel fader. Most mixers have a "Pre" button that allows you to enable pre-fader mode. If you don't have the button pressed, your auxiliaries are in post-fader mode, which means your channel fader will affect the signal level of the auxiliary output. For monitor mixes, you usually want to use pre-fader so you can control monitor mixes independently from the front of house mix. Some effects processors will be better to run post-fader, though, so don't always rely on pre-fader.
  • Step3:
Send out your auxiliary sends. On the back of your board, you there are the auxiliary outputs. For a monitor mix, you will use these outputs to connect to the inputs of the monitors. When using an effects processor, you will use the auxiliary output to connect to the input of the effects processor.
  • Step4:
Plug in a return if necessary. If you are just doing monitors, you do not need returns to the mixer. When using effects processors though, you need a way to get your effected signal back to your mixer. Take the output of the effects processor and connect that to the return input on the back of the mixer. Now you will have to adjust the return section on your channel strip to get the desired signal.
  • Step5:
Use the auxiliary knob to set the desired level. Once you know if you are running pre- or post-fader, and you have your inputs and outputs all correct, you can start sending signal to your auxiliary output. Turn up the auxiliary knob until either your monitors are set correctly or until you have the desired amount of signal going to your effects processor or other outboard equipment.

Possibel PSU Issue?


Could be a failing power supply as you suspect. You don't indicate the age of the equipment, but that could be a factor.

Just bought a ps-6 today, tried it through my overall set up the pitch shifter, detuner & super bend are fine, as soon as i use the harmony setting it takes a sweet medium gain lead sound and adds the...


By ading in the harmony signals you are combining 3 signals so gain is probably going to be high you will have to reduce it before it goes to the amp or turn down the input gain of the amp.

NEVER use a pedal in the external effects loop of an amp as the levels are wrong.

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.

How to connect effects processor to mackie 1602 mixer


Should be an Aux 1 or 2 output jack on the right side of the mixer. You can come out of the 1 or 2 OUTPUT jack to the input on your processor, and then from the output of the processor to Effects return or to a channel input. By going to a channel input you can then blend the processor's signal with a slider into the sound system with the other channels, while adding tone if needed. By going back into the Effects return, you just blend it overall by adjusting the Effects return knob.
To feed the channels through the processor, turn the AUX 1 or 2 knob up on each individual channel you want to go through the processor. Make sure the AUX 1 (or 2 if you are using that) MASTER knob is turned up on the right side of the console, otherwise nothing will go to the processor. You should see the processors' input light showing signal, if not check your connections. Good luck

I have an SWR workingpro 2x10c combo solid state amp. When running a signal into the standard input with all pots set at 12 o clock, the signal sounds very distorted. I have tried a basic troubleshoot,...


You haven't told us what "signal" you ran in... Make sure ALL interconnected equipment is powered from the same receptacle. All audio lines should use balanced interconnects where possible using XLR or TRS cables. Cross connect another amps preamp into the effect loop input to check the power amp portion.

No vocal sound


It sounds like the guitar level input to the unit is too low.

NOTE: With this product you MUST use an amplified or electric guitar that has a preamp within it.

If you have a straight guitar that does not have an amp in it, buy a preamp to first run the guitar through.

Static Noise from guitar amp.


I take it you have made sure that both the cable to the distortion box from the guitar and the cable to the amp are both good. From the description you give, it sounds like there is no signal getting to the pedal. If the cable is good, then the next likely suspect would be the input jack on the fuzz box. Try wiggling it a little with the guitar cable in place to see if it is loose. Some input jacks are unbelievably cheap and flimsy. A crackling sound (static like) is almost always a bad connection. If it was the output jack, I would think that the guitar signal would come through a least a little bit, but you might want to try wiggling that one, too, if the input jack isn't the culprit.

Another possibility to check is the battery, but this doesn't seem as likely. Some effects units devour batteries, especially units that use 9V batteries. I have a multi effect pedal that kills a 9V in about an hour.
