I did try but it seems that the mono is sent to one channel only.
Do I need special wired mono cables ?

Mono is all it can acvomplish in that scenario  as per the diagram example and schematic already posted here

No , it works fine in stereo,  the sound is great going into split - out on channel 1 and - to input 3 -out in mix output.
(the problem is mixing in the mono channel  out on channel 2 to input 3 which goes to Left instead of in the middle.)

The stereo image of GP-10 is retained but with the EHX Freeze in the left channel

I'm wondering if a mono1/4" cable to one stereo1/4" might work.

And that's where your bribing inputs that will have an effect on every stereo input which is what I was saying previously. Your going to be shorting left and right across the board.

Best I could find in small form factor when building my vg99 rack was this W-audio mixer. Basically same as Mackie MX5. One mono in, 2 stereo line one plus stereo tape in and tape out besides master out and phones.

I had to cut down the knobs on channel one due to iPad overhang from itrack it was next to

Actually have s look at Yamaha AG03 - 2 stereo, 1 mono and smaller.

Battery powered 4 channel stereo - cheap!

Help me here I'm no tech guy , I hated the time I spent in high school trying to learn about electricity, ac or dc.

How would that be different than having a stereo1/4 to stereo1/4 cable ?
Which is what I'm using with the GP-10 , if I'm using that without stereo FX it works fine.
Because the left and right are not separate all the way through?

If so it's either a splitmix in mono or a splitmix in stereo

The art splitmix is a stereo mixer with 4 stereo inputs ( or mono )
Or the other way around , or a combo of both functions
Sounds and works great
but it seems like it's not working as I want it to.
if the Freeze would been a stereo fx I could have used the Art splitmix as I hoped.


The problem with all these small mixers are the send return

Re Splitmix as far as I can tell, the only way to get your mono signal out of both left and right outputs is to put the same mono signal into both left and right inputs and that means effectively your shorting the left and right input together to get that single signal into both.

And because everything is essentially ganged together to get a stereo output the left and right change of any stereo input you attach now have a route to each other's respective inputs by nature of that short. I  other words shorting the mono across one set of inputs will short all inputs as far as I can see. I say short but thus will be to a degree based on the setting if variable resistors. I can't see how you can keep your stereo image in tact.

Interested to hear others thoughts but ultimately I guess you have to try it and see

Smash

The problem you have is that you want the freeze not to pass audio through it when not in freeze mode otherwise I think you're getting a feedback loop.

Thank you helping out.

When I first tried it I had the Freeze in both left and right
I don't know what I did , maybe a half inserted stereo plug ?

All these crap would be solved if there atl least where a stereo "bypass' on guitar fx , like on my old lexicon Jamman. The looping is in mono but the signal passing through is stereo.

But using FX loop you're going to have L+R plus the mono through of the freeze.

The only answer is surely 2 freeze pedals to maintain stereo integrity

the EHX Cathedral Stereo Reverb has an "INFINITE" Freeze mode

I tried it but it's a frozen reverb, good but not what I'm looking for.

Using fx loop does mean a very small direct signal of the signal in mono,
but I tried it and it's not an issue.

The last seems to be the best answer though.
At the moment I'm sending the Art splitmix back.

I should say that it's an impressive tool if used in either mono or stereo.
Good sound , small and cheap.
( I might keep it for other stuff )

And I'm sticking the fing Freeze in a kitchen drawer for now.
I've used it in the SY-300 and AD-10 send/return
but .... it's not perfect.

I did resort back to the solution I use with SY-300.
Using guitar out from GP-10 to EHX freeze and into a pocket pod using the direct out into aux in on the GP-10. So now it's in stereo with FX etc and speaker emulation but with a different sound then the GP-10.
That in itself isn't a problem except for the direct signal in EHX freeze.
Adding a volume pedal in front takes care of that but makes the freezes a double affair.
So I'll look into modding the EHX effect level and see if it can be made into a real mix and taking out the direct signal when turned clockwise.


Almost like this but not quite

The Rolls MX28  Stereo MINI-MIX VI is a great sounding device in a tiny form factor.  Can easily fit under your pedalboard.

It has 3 stereo inputs (3 sets of 6 channels), can convert a mono channel to stereo (just use only the R input), volume/pan for each channel, and seperate levels for master and headphone out.

ANLEON MX400 Low-Noise 4-Channel Mono Line Mixer for guitars bass keyboards mix and 5-Channel Stereo Mixer - All in One


The 4-channel mixer function is suitable for guitars/bass/keyboards mix
Ultra-compact 4-channel Mono line mixer for instruments
Highest sonic quality even at maximum output level
Input Level control for each channel Ultra low-noise operational amplifiers for outstanding audio performance
5-Channel Stereo Mixer : The unit mixes up to five stereo signals such as CD/TV/phone/MP3/Mac Mini/PS3/Xbox/ FM Tuner/ Phono Player/ Echo/Alexa/Chromecast and more.

All signals are mixed via stereo 100K ohm potentiometers to 1/8" headphone output .

QuoteMX400 Line mixer

MX400
Could it be used to mix 3 keyboards?
Certainly, as long as you are using 1/4″ plugs (standard instrument cables) you could mix any sound. I use it to mix three different bass (guitar and upright) signals. Works great for me.

Does this provide phantom power for condenser mics?
No,  no XLRs.

4 x 1/4″ mono input jacks, Output on 1 x 1/4″ mono jack.

5 x 3.5 stereo input jacks,  Output on 1 x 3.5″ stereo jack.

I have a zoom 504ii effects pedal i want to send the effects pedal through this mixer to the amp while plugging another guitar into the unit can I
Yes...you'll just need to adjust the gain of each instrument depending on it's output.. MX400 is a 4 channel mono mixer. So any mono signal can be mixed and volume adjusted for the final single mono output.

Is it compatible with cellphones
As long as the phone had a 3.5 mm audio/headphone jack, it should work.

Is the output Stereo or Mono?
STEREO & MONO ,
5 x 1/8″ (3.5mm) stereo
3 OUTPUTS – 1/8″ (3.5mm) Headphones, Output to speakers, and REC OUT stereo jacks for 3 simultaneous outputs. 4 x 1/4″ mono input jacks, Output on 1 x 1/4″ mono jack.

would this be suitable to mix 2 to 3 vocal microphones for a podcast recording?
Absolutely No. It is not a mic mixer, it is a line mixer. The inputs are designed for signals up to +16dBU. A microphone signal is usually around -55dBU. Also, a mic has an output impedance around 200 Ohms and expects to see a 1200 Ohm input. The MX400's input impedance is far higher than that. Finally, most microphones have a balanced output on a 3 pin XLR. This mixer has unbalance inputs on jack sockets.
While it would certainly mix mic signals, they would not sound right and would be horribly noisy.

hello
just got sy1000 and it sounds great plugged to two ik monitor tmt. i'm tring to use trio plus with it, but if i use send/return of sy1000, moving s/r block near the symixer block sound quality becomes really poor. should i use an external mixer? which? and which is the best way to make sy1000 and trio work fine?
i use this:
guita - bossve2 - trio-sy1000-strymon bluesky

If you want a small inexpensive but good passive mixer for volume only
then I'd suggest this one. ( bs no real sends but it can be done by patching , we'll sort of , no eq )

There's one but , only mono or stereo works , not both at the same time, other than that it's great.
