Hi, I currently have the following equipment and looking to create a single portable pedalboard which I can connect to my monitor (Yamaha DXR10)

Boss GT-1000
Boss AD-10
Boss VE-500 (soon to purchase)

I use the GT-1000 with my telecaster and AD-10 with my Yamaha acoustic

(Not at the same time)

I have a Yamaha MG10XU mixer but over kill I think to add to the pedalboard.

I need a small line mixer or something to take a feed off of everything which I can then run a single cable to my monitor..

In addition to this, I need to have an output which I can send all signals to a PA system.

Any suggestions ?

Many thanks

Alan

Hi, I like the look of the Key-Largo

Would this be ok for guitar effects even though it's designed for keyboards?

Many thanks

Key Largo Works well with Guitar FX  - set them to LINE OUT Mode.

I'm adding a Q to this thread.
I need the smallest (size and weight) line mixer
To add a fx send in mono to my stereo set up.
I really only need one line in stereo and a fx send/return in mono.
I want to add fi exh freeze etc between GP-10 and my stereo looper.
I want it small enough to have it in the carry on with the GP-10 , DD-20
I've tried to find something but haven't been able to.
Any suggestions?

Key Largo has been one of those pieces of gear that go 'I can see circumstances where I might have need of that one day', principally the reformation of an old band where I spent all my time at the outer limits of pitch-to-midi, and where I'd be instantly incorporating the VG99 and MainStage with my Axon and hardware synths.  If they ever reformed, I'd buy one in seconds!


https://www.soundonsound.com/reviews/radial-key-largo


But I think it really is one of those swiss-army-knife things that any self respecting member of this forum ought to have on their radar ...


QuoteAlthough intended primarily as a keyboard mixer/performance pedal, the Key Largo also has a lot to offer guitarists, especially those who play live with preamplifiers, amp and pedal modellers, load boxes, loopers, computer-based virtual amps and such. I've recently been expanding my own horizons in this particular area of endeavour so, since I'm already synchronising a looper and a drum machine via MIDI, alongside playing through an analogue preamp connected to an audio interface that allows me to access various bits of amp/cab modelling software on my laptop, the Key Largo certainly provides a useful method of compacting my studio setup for stage use
Main rig: Barden Hexacaster and Brian Moore i2.13 controllers

My only complaint with the Key Largo is there's no headphone out

I'm actually going to modify mine-
I acquired a headphone output PC board from an Ebay vendor along with a aux input which I use all the time

The smallest mixer I can find with an fx send/return is the Behringer Xenyx 802. Smaller line stereo mixers are all over the place & you could conceivably work with split cables and the tape ins & outs, but I doubt the end result would be more convenient.
Take what you need, put back a bit more, leave the place behind you better than it was before :-)

ART Split­Mix4

I need some help with figuring out if I can use it in this following way.


From GP10 stereo into the Splitter input and out Stereo output 1 and back to input 3 + mono output 2 to EXH freeze back into input 4 and out through mixer out setting the mix with volume knobs. The Gp10 still in stereo with EHX freeze added to mix in mono.
(the inputs and outputs are mono/stereo)

Is it a possible sollution or am I overlooking something ?
I'm not at all sure  ???

The ART Split­Mix4 is perfect in size , passiv , no power needed.
If I can get help figure out if I can do what I'm hoping for.

The freeze is mono so to send same signal to l and right you're effectively shorting the left and right input then blending that with fully stereo signal.

As this is passive won't this have some kind if effect on stereo integrity of gp10 signal as there's a l r short further up chain?

I'm not quite sure what you're saying.
All the inputs and outputs on the art can be used as mono or stereo as I understand it.
One of the first loopers I had , the lexicon jamman, had stereo through but looping in mono.
Do you mean this would be different then having a mono fx send on a stereo source using a regular mixer ?

And is the patching I'm trying to do with the art SPLITMix possible?

Update
I tried the Freeze in a small line mixer.
GP-10 in stereo - out stereo main aux send feeding EHX Freeze from both L&R and return in mono.
Very little did the freeze affect the stereo image from the GP-10
Barely barely noticeable. One thing affecting the stereo image is the direct signal in Freeze that's always there but with the mix on Freeze turned up to max, the level of the Freeze effect is very much stronger than the direct signal going through, with the level I want Freeze fx to have.
So I guess that works.

The Q remains if this is doable in the art SPLITMix?

Yeah I didn't explain myself very well! Wouldn't expect problem with active mixer - I was thinking as the art is passive unless there's some sort of decoupling to get a single source out of both left and right outs there must be bridging somewhere so my thinking was this is a potential route for the gp10 signals yo bleed over each other. Left bleeding to right and vice versa. How much no idea but jist wondered if it could jeopardise the stereo image of the GP10.

Ok got ya
Here's a review that might help apart from the stereo and mono aspects and that I'm thinking of a reverse approach ( in a way )
Also I'm trying to combine a stereo and mono input.
As I'm not a tech guy I have not enough knowledge about input- & output impedance etc etc
and could use some advice.

From https://www.soundonsound.com/reviews/art-splitmix4
QuoteInternally, there are, in effect, two stereo buses. One serves as the 'Split' distribution bus, fed from the Split input socket to the four split outputs. The other is the stereo Mix bus where the four mix inputs feed the Mix Out socket. The cunning part is that the Split bus is routed via the switching contacts on each of the four Mix input sockets, and the Mix bus is only reached via the switching contacts on the four Split Output sockets.

Connecting each corresponding pair of Mix Input and Split Output sockets is a stereo ganged 100kΩ potentiometer, which serves as that channel's level control. (For the technically minded, there are also sets of bus resistors to help isolate the channels from each other).

In essence, plugging into a Mix input disconnects that channel from the Split bus, while plugging into a Split output disconnects that channel from the Mix bus. So, with nothing connected to any of the Mix inputs, a source connected to the Split input is distributed to all four Split outputs, with each output having its own independent level control.

Similarly, with nothing connected to any of the Split outputs, the four Mix inputs reach the mix bus to appear at the Mix Output, with their relative contribution levels set with the corresponding level controls.

Alternatively, if a source is connected to a Mix input and the corresponding Split output to a destination, that signal path is completely isolated from both the Split and Mix buses, and the signal is simply passed straight through via the rotary level control

QuoteAs with any passive signal path solution, there are some technical caveats. For a start, the input and output impedances vary considerably with the configuration and volume control settings: the input impedance ranges from 25-100 kΩ, and the output impedance from 1-4 kΩ. Secondly, there's some inherent loss of level through the unit, even with the level control at maximum, typically amounting to around 12dB. Consequently, this unit is only practicable when used with active electronic sources and destinations that have very low source impedance and high input impedance. So we're basically talking here of electronic keyboards, drum machines, mixers, powered speakers and recording devices; it can't be used directly with microphones or electric guitars as sources, or with headphones or passive speakers as output devices. It's also important to keep cables as short as practical to avoid the potential loss of high frequencies.

Does this mean that if I insert a regular 1/4" mono cable that it'll work in mono?
in other words , no special plug needed ?


QuoteOverview

The SPLITMix4 is a fully passive hybrid mixer that offers a wide variety of configurations. Mix 4 stereo input channels down to 1 stereo output, split a stereo input signal to distribute 4 stereo output channels, or combine the configurations for a wide range of applications. You can even configure the SPLITMix4 as 4 stereo input channels thru 4 independent level attenuators to 4 stereo output channels.

Independent stereo level controls are provided on each channel. All 1/4-inch connections are stereo TRS (Tip, Ring, Sleeve) and all channel connections have intelligent switching to allow for a wide variety of configurations. Plugging into a mix input channel removes it from the splitter bus, and plugging into a splitter output channel removes it from the mix bus. Stereo or mono operation is determined by the type of 1/4-inch plug and cabling that you use.

The fully passive design of the SPLITMix4 has no active circuitry to add noise or distortion, and virtually any signal level can be handled. The Level attenuators cover a wide range and offer over 90dB of attenuation and channel isolation. The SPLITMix4 is designed primarily as a line level device with medium input and output impedances.

the manual is not very helpful.

upon further thought the ART Splitmix is not ideal for your needs

( what you see here is what you get

while either KMI K-Mix or Radial Keylargo will work

They might be easier to work with but they're way too big.
I need a small unit , to have with a gp-10 ( or AD-10 ) , dd-20 , a exh freeze (+ sometimes a SY-300 )
along with cables and ac adaptors , in my carry on.

All I need is one mono send/return from one stereo source and it looks like the Art can do just that.
But there's none to to try here ( out of stock) ,  so I have to get it from Germany , so it's not so easy to return if it doesn't fit the bill.

and 2 outputs.

Appears this may only work in Mono

Not as I read this review.
QuoteFor my application, I've connected two stereo keyboards to inputs 1 and 2 (with independent mix levels controlled by knobs 1 and 2), and then looped the Mix Out to the Split Input so that I have duplicated outputs available with independent level controls on Split Outputs 3 and 4. The first goes to a stereo DI box for the FOH sound feed, and the second to a pair of local, powered monitors. It's a very compact solution that needs no power, adds negligible noise and distortion, can't be overloaded, and sits neatly on the top of the master keyboard within easy reach!
https://www.soundonsound.com/reviews/art-splitmix4
I'm hoping it'll do both stereo and mono at the same time though.
And the other way around,  in other words from split to mix.
In any case I ordered one , so update pending.
