Can you explain more about the "Headroom: +9dBV using 9V power supply, more with higher voltage power supplies"? Can you give us an idea about the increased headroom numbers at the various input voltages? (ie - 9V vs 24V)

Thanks!

Basically, it can handle an 8V peak-peak signal with a 9V supply. With a 12V supply, it can handle 11V peak-peak, 24V would be 23V peak-to-peak, etc.

For reference, standard line level is 3.472V peak to peak, and most digital pedals start clipping around 4.5 volts peak to peak.
 
The Micro Line Mixer is now up for sale! We've already done final assembly and testing on some units and are ready to ship them.

Is this all we need to be able to do a parallel on a PBC 6x? I’m just curious, if I connect my 2 h9’s all 100% wet outputs to the micro line mixer from loops 5 and 6 on my PBC 6x and nothing is going back to the return jack on loops 5 and 6 on the PBC, then my dry signal from loops 1-4 can pass thru loops 5 and 6 with nothing on the return jack?
 
Basically my question is do I still get the dry signal out of the PBC 6x output jack if loops 5 and 6 outputs going to the micro line mixer and nothing plugged in on their return jack on the PBC 6x?

Yes, correct. If nothing is connected to the loop returns, then the signal at the main output will come from loops 1-4.
 
Is there anyway to kill the dry signal remotely with a PBC6x? I’m currently using a Suhr minmix for certain patches to remove the dry signal. The one thing the minmix lacks is the level controls.

I'm sorry, it doesn't have that ability.
 
Ron, follow up question. So, is it fine if I use a Goodwood interfacer as my Guitar input and my main out while using the micro line mixer? This is going to be my set up: Guitar in> Goodwood interfacer>Pbc 6x (loops 5&6 H9s out to micro line mixer (wet inputs)> Pbc 6x out 1 (dry)> micro line mixer (dry input)> Goodwood Interfacer> Amp.
 
If I run 3 stereo pedals to the inputs of the wet section, but also run a stereo wet pedal after my drives/amp into what would be the dry input, couldn’t that work as essentially 4 wet effects in parallel? I understand there would be no true dry path because that would be affected by the 4th wet effect. But (other than the internal jumper being changed to stereo for the dry in) is there an issue I’m missing?

Yes, the dry input could be used as a 4th wet input instead. The only differences between the wet and dry inputs are:

1). The dry input has internal jumpers for mono/stereo selection
2). The dry input has its own buffer and buffered output
3). The dry input has its own level control

None of those will prevent it from being used as a 4th wet input.
 
Hi:

I'm eyeing a return to RJM and have a couple questions about my build/use case. I am leaning towards a PBC 6X combined with either a microline mixer or a Parallelizer mk2 (EFX). I am running a stereo direct rig utilizing several mono drive/compressor/pitch/flanger/vibrato pedals before going stereo into a dual 'amp' setup with UAD Ruby and UAD Dream in stereo, followed by several stereo effects (Strymon Mobius, Walrus Meraki, Strymon Dig, Strymon Big Sky).

I would like to ideally be able to do the following:

1) I'd like to have the option of using the Ruby and Dream in stereo or, when I choose, running either just the Dream or Just the Ruby in mono into the remainder of my effects. Is there a way you'd recommend setting up the PBC6X to do this? Run them both in loop 6 via TRS and disable one half or the other when I don't want the other one?

2) I would like to be able to run my Delays and Reverbs in Stereo Parallel. Icing on top would be the option to run the Mobius in parallel as well, though that's a lower priority, as I would mostly be fine running the Mobius in Stereo before I go into a parallel mixer. Would the Microline Mixer allow me to have the Meraki, Dig, and Bigsky each in stereo parallel? Or would I need to put both of my delays in one and reverb in the other? Any recommendations you'd have for a signal path with this sort of build? Also, I like to run a Strymon Deco in stereo at the end of my chain. What outputs would go from the stereo line mixer into that?

Before PBC6X - Digitech Whammy
Loop 1 - Mono Fuzz
Loop 2 - Mono Overdrive
Loop 3 - Mono EP Booster
Loop 4 - Mono Compressor
Insert Loop - Mono Flanger
Loop 5 - Mono Vibrato
Loop 6 - UAD Ruby | (Lehle pedal with phase switch/ground lift) Dream
PBC 6X Stereo Out -> Strymon Mobius (Stereo) -> Microline Mixer/Parallelizer (with each doing stereo sends into DIG, Meraki, BigSky) -> Stereo to Strymon Deco.

How would my dry signal come through AND a stereo signal come out of the mixer into the Deco? Would I utilize the 'dry' output (and flip the internal switch to make it stereo) so I could have the Dig, Meraki, and Bigsky each in their own stereo send for the mixer?

The main reason I am considering the Parallelizer is that it has stomp switches, 3 stereo lines AND dry, and midi control each FX and Dry on/off. I'm interested in the microline mixer because it's smaller and could be wired under my board (saving space) and I think the 'on/off' could be handled via midi control to each of the midi capable delay/verb pedals.

Any other changes you'd recommend? Any potential phase/other problems with this build?

I had considered going for the PBC10, but my understanding is that its internal line mixer doesn't do the stereo parallel effects I'd want, and that the microline mixer or the Parallelizer are more appropriate for this use case. Fair?

Thanks,
 
There isn't really any good way to selectively use one or the other pedal in a stereo loop. The best you could do is go into the setup menu and configure loop 6 to mono. This would limit it to using only the left / tip side pedal. There isn't any way to get only the right / ring side pedal on its own.

To do what you want to with the Mini Line Mixer, you'd need to split the output from the Mobius 4 ways. One output goes to the dry input of the line mixer, the other three to the inputs of the effects.

It seems to me that the PBC/10 would do exactly what you want with regard to parallel routing - what do you feel is lacking?
 
Thanks for the quick response. I looked over the pbc10 manual and it seemed silent on whether the internal line mixer is stereo capable. Is that the case? How many stereo lines can it do? Ie could I have a stereo delay, stereo reverb, and stereo effect or delay all running in parallel so my stereo fix don’t feed into each other?

Thanks

It's stereo. You can have up to 4 effects (in loops 7-10) in parallel plus a dry signal.
