Lexicon efx are stereo, 2 in 2 out. I now run my systen inline to two amps.
How could I use the efx loop, less noise, with two amps and a Lexicon stereo processor ?
I think it could be done but I'm not smart enough to wire it without a lot of noise.

| What model of Lexicon are you using? On some models you can set it for mono input and stereo out. |

Here`s one way to do it:
A Y-cord from amp one`s effects send to Lexicons inputs, output one from Lexicon to amp one, effects ret, output 2 to amp 2, effects ret.
Some Lexicons have a left/mono input bridging, some don`t.

The Lexicon is NOT an instrument level unit and will have noise (poor signal to noise ratio) if used with low level signals. It requries line level or "consumer" line level to work properly and not be noisy.
If you have a Peavey Nashville 1000 or Nashville 112 the Post EQ effects loop is a -10db loop and will work with line level units such as this Lexicon. The Pre EQ effects loop is a low level instrument loop and will not work properly. |

Bill, what model Lexicon are you using? Marvin is correct - how you handle the interfaces will depend on which unit you have. With the right gear, you can solve the noise issue.

The Lexicon is a MX300. No mono input. I understand the loop hookup for one amp. My question can it be wired stereo = 2 amps ?
I guess I will have to use the clean amp, efx amp set up if I use the loop.

Connect one of your amps to your guitar in the normal method.
I would suggest you make a Y cable, one in, two out. Connect the single end of the Y to the output or efx send connector from the above amp.
Connect the two remaining connectors of the Y to the Left and Right inputs of the Lexicon. This will feed the mono to both channels of the Lexicon. The Lexicon should process that signal through two reverb channels making them "stereo."
Connect the left output of the Lexicon to the Effects return of the first amp. Then connect the right channel output of the Lexicon to the Effects return of the second amp. Place the amps in the correct position for left and right. Play your guitar and you should hear the stereo effect.
Use the Lexicon input or output controls as system volume control if your amps do not have a master gain control after the efx return jack. |

Marvin, I thought I already said that...

I understand that setup. The #2 amp would be a slave of the #1 amp. No EQ on the # 2.

I've just received the MX300. It took some getting used to. I almost had buyers remorse, but then got some sound to my liking. I might still use the Nashville 112 reverb and use the MX300 for additional effects, but for the moment I got the Large Hall reverb performing nicely - I think ??
Those of you who have the MX-300, listing your favorite setting may be interesting.

No problems, Bill, you're on the right track, the only problem you might have with a dual amp effects loop configuration is the potential for ground loops and the resulting hummmmm.
GTR > VP > "Y" cord >
"Y"1 > AMP1 > LEX L > AMP1
"Y"2 > AMP2 > LEX R > AMP2
Be certain that you set the Lex I/O for the proper level, as noted above, most guitar amps call for a -10dB nominal level.
If you do get ground loop noise the fix can be a tricky matter but try it first, if it works you're golden! |

Bill,
Have you developed any Patches on the MX-300 that are to your liking? |

Well, not in all cases. The older Lexicon units worked quite well with low-level guitar signals. These older units had pre and post gain controls, which would allow you to tailor the signal levels as needed. I used an MPX-100 for years, with no noise problems. I don't know about the newer Lexicon products.

| I don't mean to hijack this thread but something was mentioned in a post here that I don't understand. I am electronically challanged to say the least, but what is line level or instrument level? I no longer use a rack system and instead use a DD 3 and/or a RP 155. I really like the sound of two amps and if bandstand room allows, will use 2 amps, a NV 400 and a MM head and Speaker cab. To my ear the use of SS and tubes together sound really good. If I connect using guitar->VP->RP->amps ( using two chords, one to each amp) most times I get a slight hum or hiss. However I find if I go Guitar->VP-> N400->RP to the in and out on the back of the 400-> 2nd (stereo) out of Rp->MM head I get a great sound ( more of a stereo sound than using a chord to each amp) with little or no hiss or hum. Is this type connection line level or instrument level. It doesn't make any difference but just curious. |
