So sometime ago I experimented on using the EQ on my Lexicon to boost the 80Hz freq after the MP-1 since we all know that the bass freq on the MP-1 is not ¨that¨ good because its not placed in the normal freq range for the bass control on most amps (its actually centered @ 180Hz) and WHAT A DIFFERENCE IT MADE!!! After that I became obsess on wanting to add an EQ that was analog but controled digital to have more flexibillity................ So fast foreward a couple of months and this week I pulled the trigger on a Rane MPE 28 MIDI Programmable Equalizer on Ebay that had no bid AND at the end I was the only bidder and won the auction for just $40 dollars + $20 of shipping!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!   :banana:  :banana-dance:  :banana-rock:  :banana-upsidedown:

So I hope to get it by next week to have a fully analog dry preamp tone + EQ and the add the wet effects thru the RJM Mini Line Mixer  :banana-guitar: .

PS:
After I get that I will post what I build to place effects infront of the ADA when I want then and keep the signal pure.

Ah the big brother of the MPE 14 which is almost the same as the ADA MQ-1 since Rane bought it from ADA.

Ok so now that I'm waiting to get here (probably like 10 days) I'm starting to think how I will hook everything up and I have a little dilema:

Right now I have the outputs of the MP-1 going in to the DRY channel on the RJM Mini Line Mixer, then from the MP-1 SEND I go in to the RETURN of my Lexicon and from the Lexicon outputs I go to one of the other channels of the RJM to get the WET only delays (I also have other effects running before the wet only part of the rig but that will get explained on the future in another thread)... anyway this meens that if I run the Rane in the loop of the MP-1 I need to have a Y-BOX to: A) go back to the RETURN of the MP-1 so that the outputs have the added eq and B) on the added splitter output go to the Lexicon.

What would you guys advise on this scenario?

Hey El, the Rane has both XLR and 1/4" RTS jack in and out. So you may be able to use either the 2 inputs or outputs as your "Y" splitter (but both XLR and Jack are balanced so may not work ?) but if the signal is paralleled between XLR and jack it should be possible to "Y" split like this at either the input (if you don't want eq'd signal to Lex) or output (if you want eq'd signal to Lex) using XLR to mono jack (if that's what Lex return is (i.e. jack)), so Male XLR to Jack to "Y" from the input side or Female XLR to jack to "Y" from output side. Another way to pick up eq'd MP1 for the Lex is from headphone out.

Ok so this is what I totally love this forum because it has opened my eyes to stuff I would know of considered on my MP-1......... by rnolan comment I just realiced that a) the headphone out of the MP-1 can be used for connections in the rack and that b) since it's placed after the MP-1 loop it will picked up anything that is put in the loop, but now I have some questions to understand this better:

1) is the headphone out placed before or after the chorus in the internal signal path of the MP-1?
2) since the headphone out is stereo then the connections (if the previews question is correct) should be as follow: since the MP-1 SEND is mono I should use the loop to add the Rane EQ and then go from the headphone stereo out to the Lexicon jack returns... that way I will also get the MP-1 chorus in the wet delays for example!
3) and if comment #2 is correct then all I have to do is to run a Y cable (1 TRS jack to 2 TS jacks) from the MP-1 headphone out to the Lexicon jack returns

So my only other question is what level is the headphone out of the MP-1 to correctly set it up with the Lexicon? BTW I have meters to show what are the levels in different parts of the Lexicon signal that I can also use to set the level to the same as my conections now I guess.

PS:
Comming back to the Rane, I believe that the correct way to set everything up is that the signal going to the Lexicon should have the EQ correct? Also, yes the connections are balanced but in the manual it says that to have them unbalanced just make a cable that leaves  open the (-) connection that would go from Pin 3 of the XLR to the Ring of the TRS. Now the only question is if I can run both outputs of the unit at the same time for the Y options that you mentioned before.

Hey El, there's so many ways to patch things and even if they aren't "optimal" it helps your understanding  :dunno: so always worth a try.

When I first got MP1 I combined it by using headphone out to rockman XL100 headphone in and rockman headphone out to 2 Marshalls (with resistors to lower the voltage).

The MP1 headphone out is after everything like the main outs. I'm not sure if it's tweaked to not be too toppy ? as the idea is you can listen to your MP1 without disturbing anyone (bedroom etc). So it has loop + chorus etc, sound is (much) the same as A/B outs. It's designed to run headphones @ 600ohms or more, the returns on the Lex should be ??k ohms so should be no problem there. IIRC there is a headphone out level control ? which should be independent of the main (front panel) output level which controls A/B out levels (but need to check that). So to get the right gain/balance into the Lex returns use this (hp out) level control and Lex return level settings (pick +4db on Lex). And yes a TRS > TS/TS to connect.

To put Rane in MP1 loop, just use mono TS > TS jack leads into/out of the Rane jack sockets (leave the XLRs out) and adjust for unity gain (no overall volume change from loop in or loop out), use MP1 loop level control and then Rane in/out level controls (which I assume are programmable per Rane patch) to get right for each Rane eq patch.

If you have 4 inputs on your mini mixer, you can have say MP1 A/B outs > chan 1/2 and Lex L/R outs > chan 3/4 and balance how you want.  If you adjust the MP1 and Lex patches you can have any balance of the 2. Say you want MP1 with Lex FX but no Lex guitar sounds, make a Lex patch that just has FX and guitar sounds = 0, if you just want Lex (no MP1) make MP1 patch all 0 (just MP1 master set to 0 will do this but best 0 everything so less noise). So that's the 2 extreems, any balance in between can be dialed up with different patches (so do patch pairs to get what you want, remember MP1 goes 1 - 128 = 0 - 127 in many other gadgets so MP1 patch 100 may = Lex patch 99 ?? etc)

Of course you have to split the guitar signal between Lex and MP1 (obviously) for above.

I just got an answer from Rane (quick feedback!) and they say that I can use both outputs at the same time... so I guess that when it gets here I'll be having some fun experimenting with different ways to connect everything together and will post the results jeje. Cheers!

Hey El,  :thumb-up: enjoy the journey  :metal: but as you connect things, just keep gain structure in mind.

since Rane bought it from ADA.

I never knew that. I have an ME60 I love. Enjoy El Chiguete, RANE makes killer gear.

Hey EC

Well the headphone signal is taken just before the front pot signal.So this pot won't have an influence on the headphone volume.
Now you can't actually use this signal for your signal chain since it has a sort of cab sim build in.
As for the mixer connections,i'm going to leave that to the specialist from down under  :thumb-up: :lol:

Well sort of cab sim on HP out (as MJMP says, and I suspected but didn't really know), it makes sense (this was probably the begining of the ADA cab sim journey), if you want a head phone out of the pre amp, you want it to be indicative (as close as possible) of/to the main outs which go to power amp/cabs. Since HPs are full range (like studio monitors), there would be too much top end in the "live" patch (as 12"s don't do tops that well), cab sims do a few things, but the main thing is to reduce the highs so it sounds like a (speaker) quad box etc. So for MP1 HP out to resemble the main outs (freqency wise) it needs to "cab sim" a bit.
So for "just" using Lex FX and MP1 HP out for tone, this signal is ready to record with no other cab sim needed. To go to poweramp > cabs instead, you may want to wind in some presence (or tops) depending what variation the HP out causes.

Important to understand what each bit does so you can create the sound/tone you want
