PML-2 Mini Looper



http://www.nuxefx.com/product_detail.php?id=78&id1=52&id2=0

PML-2 offers two audio loops that can be switched by using an external foot pedal. If you are using two rigs on stage or studio that need to be switched often, you will find this portable PML-2 easily solves your problem and saves your time! It's true-bypass to make sure there is no signal loss.

PLS-4 Four-channel Line Switcher
PLS-4 is a four-channel Line Switcher. You can use an extensional footswitch pedal to select one of the four channels. For example, plug the guitar to the INPUT, send the sound to 4 different amplifiers, and select one of the amplifiers. Or, input 4 audio devices to PLS-4 and select one of them to output.
1 input to 4 outputs, or 4 inputs to 1 output

Hello,

I just ran into these, and saw this nice listing & overview here, thanks. 
(Nice boxes, and indeed inspired by the Rockman. FWIW, the MIDI-unit also makes me think a bit of 1.5 times the Nobels MS-4)

Was wondering how the audio is switched - mechanical relays ? Or FET-switching ?

If anyone has hands-on experience, I'm curious to hear if therey're transparent & how click-less are they ?

Thanks!

Elantric

Both Nux boxes use mechanical relays and there is a slight "click" in the audio when engaged

But they have a transparent sound and no distortion and no introduced hiss. they work well at this price point

(under $40 each)

MotorBongo

Thanks for the info, that's good news! 

Nice they're using mechanical switching, so no issues with level limitations either (as long as not using speaker signals). 

Too bad there isn't slightly more flexibility for the PML-2 for say dual indep loops*  and/or having all TRS audio jacks for stereo and or balanced, but at these prices one may not complain.

Thanks!


*: the manual mentions the REMOTE connector being a 3-conductor type, but that will be some copy/paste error from a related manual, so not an added 'advanced' function

there are other audio switchers  - the price / performance leader is the Joyo PXL-Live

Nice, hadn't seen these now also have MIDI added. Thanks for posting!

Let me correct myself
- I realized later that if you're only needing 'half of the pedal'
(say a selection of 1 source into 2 destinations,
or 2 sources into 1 destination),
then the unused audio connections can be used for a second 'deck' of the same functionality.

That assumes that the internal audio-path is unbuffered, no additional electronics, so just the mechanical relay contacts.   

This gives this box the additional 'extra deck' possibility,
and is also the reason that say a Boss LS-2 can't do that,
because there it's all done with active electronics, so the signal direction is just one way,
whereas for a relay the contacts don't object if the signal travels in a reversed direction.


BTW, I see no mentioning of this in the NUX info, but I assume multiple of these boxes can be 'locked' mechanically, side by side to each other ?

Bye

I get your point, agreed, all comes at a price.

Yet I like the modularity of those small NUX (& other) building blocks, for implementing own idea's about signal flow (which stubbornly never fully match with even the greatest most expanded ready to go boxes out there - one could adapt a bit though, but that might be a later insight ;-) )

Did you happen to use some of the NUX modules I understood ? Do these indeed lock side-by-side to each other ?

Bye/Thanks

True Hardwire stereo AB switch


Built-in buffer switch for low level signals


Routes your signal to 2 different set-ups


Routes two stereo signals to a single stereo in


Protects the natural integrity of your sound

A true hardwire stereo A-B switch. PolySwitch AB is the perfect solution for guitarists looking to route their signal to two different set-ups – even in stereo – and easily switch between these.


PRECISION VERSATILITY

Not only does PolySwitchAB let you split your stereo signal and switch between outputs. It also works "backwards", letting you run two separate stereo instruments into a single amplifier or other signal destination. And with every input and output available in stereo, it's a great solution for keyboardists or anyone else needing to route a stereo signal to two destinations or two stereo signals to a single stereo in.
SIGNAL INTEGRITY

As you'd expect from a T-Rex product, PolySwitch AB is specially engineered to protect the natural integrity of your sound – all the way through the signal path. True hardwire signal routing, top-grade electronics, and a built-in buffer switch for low-level signals caused by long cables, for instance, make sure you don't lose a single ounce of your precious tone.

Thanks for the info, good to know!  Surprised that they don't, they seemed a bit weird on pics, so thought they'd be meant for interlocking.  Good to hear the sides can be removed, thanks.

Thanks for posting! ~Comparable functionality as the NUX (aside from the buffer), but with more straightforward connections, and I figure better quality/longevity.

Best regards

Looking through the manual I think the TRS 3 conductor type is odd. The NUX controller PMS has TRS outputs and I'm guessing they are supposed to work together. Not sure what would happen if you just stuck a TS 2 conductor footswitch in there?
Would be interested if anyone could conform the operation as this could be useful to add further HW control from a MIDI foot controller like the FCB or ROLAND FC controllers with amp switching outputs.

Without having any of these units yet, one would assume you need an insert cable (TRS to TS + TS) to connect the 'MIDI-brain' & the 'switcher'.

Elantric

Its very common for a 1/4" TRS Jack to provide two Relay controlled switched GPIO controls

Same type exists on Line-6 Helix as "Amp Control"

Use a TRS insert cable if you need to route to separate 1/4" TS foot switch jacks on your amp

or if using PMS with the PML-2 - read the manuals



SLICK

Hmm looks like the tip and ring control the two loops independently.
Assuming there is a third state with the signal passed straight through as it states true bypass.
I'm thinking that if you had a TRS cable and connected a single switch amp  control to the nux you could still get single loop control that way.
At this price it's definitely worth a shot anyway.

You mean of the PML-2 looper ? That's be interesting/usable. Don't know if you have the unit available already, or basing this on the manual ?
(description in the manual isn't consistent/complete)

Curious!

Thanks/regards

SLICK

Yeah read the manuals is always s good starting point. Unfortunately I think some of the nux ones have lost a little in translation.
Anyway from looking and guessing that these work logically together......
The PMS controller can pull either the tip or the ring of a stereo cable to ground.
Now it's not clear from the manual but I suspect that on the PML tip to ground would Activate one loop and ring would Activate the other. With neither tip or ring grounded the PML should provide a straight through with no loops active.
No one knows what happens if you have both on until someone buys one 😃

Going to have a look and see if I can find one.

If the PML-2 would work as you described that'd sure make it (even) more usable, but to realize all that it'd require more switching-circuitry.

In its simplest form the PML-2 can just be one straightforward DPDT-relay that is controlled by one control signal.

The additionally hoped for functionality (in which I'm joining you  ;) ) requires more switching contacts & poles; the equivalent of say two DP3T relays.

I assume they kept it simple, intended for insert-cable wiring and the Ring-contact of the PML-2 control input is an error in the manual.


I saw them on eBay, with free shipping.

On the subject of NUX tools, I am having no luck at all programming my PMS-2 MIDI switcher.  There must be something critical I'm missing, but whatever I do it fails to save the switch states.  Anyone else using one of these?
