Looking for a small 4 channel balanced stereo TRS mixer

#21
I have a Samson SM10 for mixing multiple pre-amps. For the short run between the pre-amps and the mixer I haven't needed balanced inputs, but it has them. And it has balanced XLR outputs, as well as TRS and a monitor out that I use for a common tuner.

SM10 | Samson

Ideal for stage, studio, and installation applications, the SM10 Line Mixer is a versatile and reliable addition to your audio setup.

Looks like 8 mono channels rather than 4 stereo? I suppose it might be workable. But I really want one fader per stereo channel and don't want rackmout form factor.

But thanks, that led me to this, which seems possisbly perfect, exceep it also has 4 extra mono channels I don't need - but if those jacks handle TRS balanced, it'll do just fine, eve only using haalf of it...

Edit: looks like a GO:

Inputs - Line:4 x 1/4" TRS, 8 x 1/4" TRS (4 x L/R)

No not from experimentation, Right now one channel I have a stereo TRS 1/4 to 1/8 connected to my phone on channel 2 and I did a left right sweep

Remember MiniMix Pro -

It also says it in the manual and the diagram, The left is stereo TRS, The output although will work on TS is recommended to use TRS left and right (balanced out)

If you haver balance out from your device, you can use TRS even on the individual channel in,

Maybe read the manual again.

What you highlight is the output definition. But below that it describes using the Left input for TRS (Tip-Ring-Sleeve):

ah, well, interesting, but yeah, not what I want. Two TRS jacks per channel, please, L and R stereo, both balanced TRS (mono).

Anyways, ao unless Saturnworks comes in cheaper with custom, I'll probably go with this Samson. I could even use the 4 additional mono channels as 2 stereo channels, using the pan knobs etc. Just enough to fit my 2 keyboard synths in too, which could be useful.

I need a submixer to premix the outputs from my guitar synths, hoping for a small compact 4 channel mixer with balanced stereo TRS inputs (so 2 TRS jacks per input channel plus 2 for output) - anyone know of such a thing? I found a small one from Behringer that did 3 channels, but I want 4. Everything seems to be RCA inputs or unbalanced TRS stereo input...

If I understand, you actually want 8 channels linked into 4 stereo pairs.

Compact analog mixers typically have 2 stereo channels, so probably a no go.

You could use a digital mixer and link channels. Double check, but I think the Behringer XR16 would do it. Channels 9-16 are balanced TRS (line inputs).

Interesting - I've never looked into digital mixers, perhaps it's time to learn...

Well first of all a "balanced stereo" like the OP mentioned is not TRS but it will be a TRRS usually a 4.4 mm plug. Yes there are balanced 1/4 TRS outputs from synths, but I do not know of any Guitar synths where each channel output is balanced. (GR-55 or SY-1000) In fact many keyboard synths with 1/4 outputs are mostly unbalanced/ There are just a handful of synths with 1/4 outputs like the Virus or old Jupiters that haver have balanced 1/4 outputs and some Euroracks. Usually if they truly have balanced outputs they will have XLR connectors

I do own this unit and asked Rolls if I could use a TRS if I have a device with XLR outputs on both left and right of each channel and they said I could and I did. But what is the benefit really since my cable runs are no longer than 6 feet.

if the OP really needs a TRS connector for the left and right, then the only recourse is an 8 channel mixer with XLR and then he can use a TRS to XLR cable, 8 of them. It will not be small. I would verify though that the Ring of the TRS is carrying a signal, There is a good chance it is not. But if he needs a stereo TRS which is unbalanced then all he needs is a TRS into the STER input of this little roles. Or ask Stairworks to make one. It won't be cheap.

Hmmm, the SY-1000 main outs are indeed TS, though the left is a TRS for phones optionally. Maybe you're right, I'll check the keys too. Don't know where I got it into my head that all those outs were TRS.

But I have to take issue with your first sentence - "balanced stereo" clearly means 2 TRS jacks, both balanced, one for L and one for R. I'm certain I've got something that needs this, though I'll have to go through everything now and check them all.

The keys main outputs are definitely LR pair of balanced TRS jacks. I just assumed the guitar synths would also be, but the SY-1000 isn't. Hmmmm.
 
#33
OK but the Roland / Boss stuff (VG-99, GR-55, SY-1000) are all unbalanced TS jacks. Curious.

So I need the fancier solution for the keys, but there are only 2 of those. Not for the guitar synths, though, of which I've got 4 - 1 VG-99, 2 GR-55s, 1 SY-1000), So those simpler mixers like the Ross should work for those. Hmmm.

So much nope on this. I had already posted a viable recourse that would work just fine for what I described. Four stereo channels, each with L and R 1/4" TRS jacks for balanced lines. I don't see how you can make such a statement, I'd already shown it to be untrue.

Until you get into high-end synths, you won't find many with TRS balanced outs. I’ve been using unbalanced 1/4” connections for years without any noise issues.

Mine both do. Don't know that that makes them "high end", though each was "top of the line" for the brand.
