I have a Peavey XR-600 PA Head, I would like to know if and how can I connect a MX 200 Dual Reverb Effects Processor to the PA Head?


If it has a effects loop output and input on the p.a. head and a in and out on the reverb effects processor, then yes you can, just run the effects loop output signal into the input on your reverb processor, out of the output back into the input effects loop on the p.a. head, kinda like you would a effects pedal thru the effects loop of a guitar amplifier. hope this helps!

Onyx 4880 48 channel mixer


Are you actually sending a signal to the effects unit? normally you would have it in an insert although I know some people who take a sub channel out to the effects unit and then feed it back in through a mix channel if they run out of inserts or aux busses. What you describe above does not make sense to me. Can you elaborate with the full signal path for the effects unit?

How to get efx to work


You are aware that there are no built in effects, correct? Are you connecting an off board effects unit and having problems with that? You should be connecting the effects send on this mixer to the input of the effects unit - then the output of the effects unit to the effects return on the mixer. With the effects send control on the appropriate channel turned up, you should see signal hitting the effects unit. You'll need to adjust the effects return on the mixer to hear the effects signal included in your mixer output.

No sound from amp


First of all it is important that the amplifier must work to produce the output with an input signal. So disconnect and check with an audio test signal on the input line and at the coupling capacitor to the input. If this is fine then the fault is only the connection and it is possible that the input line has shorted and so the input is not acting. But if other inputs are working the connectors must be rewired and soldered once again without any bridging.

The unit itself is generating too much noise(hiss). some effects are noisier than others but overall noise level is unacceptable. all the product reviews say how quiet this unit is. tried changing signal...


Check that: You are using BALANCED interconnection lines (TRS or XLR) everywhere. Low quality cables can cause or let in noise and hiss.

Check that ALL, and I mean ALL interconnected equipment is powered from the SAME receptacle or power conditioner.

Check that you are not using a noisy source or recording system like the internal audio of a PC for instance.

Short the inputs to ground and see if the output noise goes away. Some effects are noisy because the inut signal after effects gets added back into the output.

You haven't described your setup and without that information there is not much more I can add. Ferreting out noise is one of my specialties. In general your input level should NOT be too small as this leads to less signal to noise ratio due to digitizing noise. Look at the Lexicon specs to find what the levels should be. Without the description of your setup I can add no more...

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.

How to use an external effects processor on the tascam neo


Manual here:http://www.fullcompass.com/common/files/10255-Tascam%202488-neo%20manual.pdf If you look at the back you will see two effects sends. Apparently from the manual you can use the line inputs for returns. This is where it might become confusing. Each line in is also a TRS jack. That means that using a common guitar or unbalanced cable will make the jack act as an input. If you use a shielded !/4" stereo cable( stereo jacks on each end) then the jacks can send a signal and receive a signal. If your effects unit has one of these jacks also you just need the proper cable. If not you use a cable with ends that match your unit and the Tascam. There are several combinations of effects assignment available and you should consult the manual carefully. I would recommend joining a support or users forum for this unit. Try this one:http://www.sweetwater.com/forums/showthread.php?t=25978 or this one:http://homerecording.com/bbs/showthread.php?t=276889 The last one is a site worth joining and I highly recommend it.

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.
