Yes, two 16 ohm speaker may be used as this contains no active components. However, the markings showing each input's impedance will not match the actual impedance.
With (2) 16 ohm speakers what will the actual impedance be then? impedance
You'd have
- 16 Ohm Left/8 Ohm Mono
- 16 Ohm Right
- 32 Ohm Mono
I just relabeled plate with a brother p-touch labeler as I setup with two 16 ohm speakers.

using a 2x12 setup. if i connect to one of the 8ohms mono connections and `INSERT AN OPEN PLUG (NOTHING CONNECTED)` into the other 8ohm connect will both speakers output sound?
Asked by Anonymous on September 28th, 2016.
No, only one of the 8ohm speakers will output sound.
How does it sense 4 ohm stereo or 8 ohm mono through the same jack?
It does not sense anything since this is a passive circuit. The resulting ohmage is determined by the ohms of the speaker.
It has switching jacks. When you insert a plug into the jack it either opens or closes a circuit to put your speakers in either series, parallel, or a series-parallel combination. The individual speakers do not change impedance, however. That is NOT possible. They all add or divide (or both) together to give you the possible ways they can be wired and the resulting impedance. 4 4ohm speakers can be wired in a series-parallel combination resulting in 4ohms. 4 4ohm speakers can be wired in series resulting in 16ohms. 4 4ohm speakers can be wired into 2 separate series pairs of 8ohms each (Stereo).

Can I run a Y cable out of one 8 ohm output from my head and split it into the two 8 ohm stereo jacks with two 8 ohm speakers? If I did that, what ohms would my amp see? I want to find a way to go out of an 8 ohm output and make the cab 8 ohms as well.
Asked by Anonymous on May 25th, 2018.
I believe this would be the same as running the two 8 Ohm speakers in parallel so the load the amp would see would be 4 Ohms. If this setup ran the two 8 Ohm speakers in series (I don't believe it does) Your amp would see a 16 Ohm load.

If running two 8 Ohm speakers and an amp rated for 8 Ohms, simply plug the speaker cable into the 8 Ohm left input and plug a dummy cable to the 8 Ohm right input jack. Your amp will only see an 8 Ohm load.
I think he wants to use *both* 8-ohm speakers at the same time, while matching his 8-ohm amp output. I do, too. So again, would using a Y cable into both stereo inputs, would the amp see an 8-ohm total load and safely power *both* speakers at once?

Again, if using a Y cable and plugging into both top jacks on the plate would essentially put the two 8 Ohm speakers in parallel, making the rating 4 Ohm. We do not suggest doing this.

If your amp has a speaker jack for a 4 or a 16 Ohm load, yes, this can be done. The first drawing in the "Speaker Z Examples" shows how one would wire a 2 speaker cab with 8 Ohm speakers. You and your son would be able to plug each amp into the top left and right jacks when playing together, and when you are playing b yourself, plugging into the 4 or 16 Ohm mono jack will make both speakers run in unison.
Thank you so much for the quick and clear answer!

See the wiring diagrams above for reference but generally you can run in either series or parallel when wiring up speakers. It's more than likely possible but the labeling may not match.
You are not going to get an 8 ohm load out of 4 x 16 ohm speakers, only 4 (all in parallel) or 16 (2 pair in series, then that pair of pairs in parallel). Wired per the 4 x 16 ohm speakers you would get the impedance's marked on the plate.
Correct, but you can get two 8ohm loads from 4 16ohm speakers in stereo.

I have a 2x12 cab with 2 8ohm speakers. Is there any way to get 8ohm mono?

You can run this at 8ohm mono but it will only be one speaker.
I have a 2X12 cabinet with different 8ohm speakers in it that I would like to be able to use separately (only one speaker), as well as together at 4ohms. Does this jack allow this? I assume the jack labeled 16ohms would basically be the 4ohm mix of the 2X 8ohm speakers?
Yes, here are your options: 4 ohm mono, 8 ohm left only mono, and 8 ohm right only mono. Checkout the plug-in schematic for how these are wired and hooked up.

First you will want to check to make sure that everything is wired as shown in the diagram and that two 8 Ohm speakers are being used (other Ohm ratings will give other readings) and if both of those are accurate, there could potentially be an issue with the plate and you may need to contact us to make a return.
Thanks for your reply to previous question asked on 7/23/19: Some clarification: With two 8 ohm speakers connected per the wiring diagram, plug in 4 ohm only input measures about 4 ohms; plug in 16 ohm input only about 16 ohms, plug in both 8 ohm inputs measures about 8 ohms each, all as expected. Finally plug in 8 ohm right ONLY measures about 8 ohms. Checking the wiring diagram this appears to be what should happen, as a plug the right 8 ohm input alone does not appear to result in a parallel connection of the two speakers and the left speaker will be disconnected. Can you look at the diagram an d tell me if this is correct or not? Thanks.

With two 8 Ohm speakers in a cab it would work as follows: Left input would be 4 Ohm using both speakers (Parallel wiring) or 8 Ohm when used in stereo (If two amps are being plugged into both the left and right input) When using two 8 Ohm speakers, the only mono options are 4 Ohm (top left jack) and 16 Ohm (bottom left jack) The only case in which it would work as you need would be if both speakers in your cab are 16 Ohm.
I use my Plug and Play exactly as the question poses. It has two 8 ohm EVM speakers. The short answer to your question is that using the PP's top left jack will automatically put the two speakers in parallel for a 4 ohm load. If you plug a jack into the top right jack, the PP splits the speakers, so each will run at 8 ohms independently (stereo). If you want to run one speaker at a time at 8 ohms that's not problem, but you need to have both jacks engaged to make the 'split'. So run your amp into one side (whichever you want), and put a 'dummy' (ie unconnected) plug or cable into the other stereo jack. It works great.

Using two 16 Ohm speakers with this jack (series and parallel wiring are a moot point as this jack plate does both) will result in the labels being incorrect. Looking at the backplate, it would read from left to right, top to bottom: 16 ohm left (or 8 ohms mono), 16 ohms right, and 32 ohms.

NO! Do not leave both amps plugged in to the same circuit. Your output transformer will fry or transistors if it's solid state. You can plug them into the 8ohm jacks though. They are separated from each other Right and Left.

As long as the two cabs you use have a matching impedance, you can use them in stereo. It does not have to be 8ohms. It could be 2,4,6,8,16ohms, etc. You will just have to remember that the labeling on the unit will not match your actual impedance.

Complicated question. If you plugged amps into both the right and left 8-ohm speakers, can the mono 4-ohm jack still be used to drive both speakers? Or do I need to physically unplug the right 8-ohm jack? Scenario: I want to use PnP in a 2x12 cabinet with two 100-watt combos in conjunction with an A/B speaker switch on each head. Combo A set to 8-ohms will switch between its internal speakers and the right PnP 8-ohm jack. Combo B, also set to 8-ohms, will switch between the PnP left 8-ohm jack—which is ALSO the mono 4-ohm jack, driving BOTH PnP speakers—and its internal speakers. Any problems with this? Basically, Head A can only drive the right 8-ohm speaker on the PnP, while Head B could drive EITHER its own combo speakers, or only the left PnP speaker, OR both PnP speakers when Combo A is switched away from the PnP. Does PnP work this way? Or does plugging a jack into the right input negate the the mono 4-ohm input driving both speakers? Make sense? Thanks—Jay Erisman, Cincinnati 513-706-8977

The jacks are connected internally to a circuit board that makes or breaks connections based on what is plugged in. If you have the right 8 Ohm jack plugged in, the left jack will only operate the left speaker in 8 Ohms. Doing as you suggested and physically unplugging the right jack when wanting to use the 4 Ohm stereo option will work as you are intending.

Just wanting to make sure I know what I'm getting into with this before committing.
I have a 4x12 16ohm cab. I'm hoping to use this to convert it into a stereo cab. From my very much layman reading of the documents on this page it seems if wired as stereo, the only option is to run it as stereo (or if you use an open plug you can get 2 speakers in mono).
This won't allow you, for instance, to plug in a 16 ohm mono signal from an amp OR the 2 8 ohm stereo without changing some wires internally. (Note the OR, I'm not meaning plugging in stereo and mono at the same time.) If I want 16 ohm mono, I need to wire it as 16 ohm mono, if I want 8 ohm stereo, it needs to be wired as 8 ohm stereo (or 2 speaker 8 ohm mono), correct?
Thanks for the response.

The two different hook up drawings for speaker cabs with four speakers are for two different Ohm ratings. If your cab has 16 Ohm speakers in it, you will want to follow that drawing and vice versa if they are 4 Ohms. Once the speakers are hooked up, simply using the different jack (as you stated, 16 Ohm mono should not be used in conjunction with the stereo 8 Ohm jacks) will do all the switching internally. If you want 16 Ohm mono, simply plug into that jack. If you want to hook up two heads and run two speakers through each? Plug each head into one of the 8 Ohm stereo jacks, and the Plug and Play takes care of the rest.

The stereo capability will be there regardless, but you are not required to use it that way. If you only plan to use this to switch between a 4 Ohm and a 16 Ohm mono load, it will certainly perform that function.

How is the PCB(?) mounted to the jack plate? Is it held on by the nuts on the jacks? Could I remove it and attach it to a a different jack plate? The jack plate provided is too big and I don't want to modify the back of my cab. Thank you!

The hex nuts on the jacks are what secure the PCB to the jack plate, yes.

I am interested in getting this to rewire my 4x12 cab, but I have a question regarding wiring... The whole point in buying this is because I want to use and have it wired exactly as a Marshall 1960 4X12 cabinet, as I am going to be running 2 heads into the cab at 8 ohms per side. But I also want to be able to use the cab in either 4 or 16 ohm mono... how is this getting wired to a 4x12 with 4 16 ohm speakers???

If you use the 4 16Ω speaker hookup chart in the "Speaker Z Diagram" this jack plate will work as you are suggesting.

If I wired an 4x12 cabinet with 8 ohm speakers in parallel each side, would I have 4 ohms stereo, 2 ohms mono, 8 ohms mono? Thanks.

Yes, those would be accurate labels if using four 8Ω speakers.

Excellent product and helped add some versatility to a 412 cab loaded with 16 ohm speakers. I run all 4 or the top and bottom two speakers separately. Easy to install, just make sure you have your wiring done properly and verify with load readings.
Changed my cab from mono to stereo with this plate. Very easy , looks great
Easy to convert a mono cab into a stereo/mono cab. Just plug in speakers and go!
Great product. Heavy metal construction. I built four separate 1x12 cabinets and installed one of these in two of the cabinets. This way I have the option of running a single 1x12, two of the cabinets in mono, two of the cabinets in stereo, or if I want to go all out, I can run all four cabinets in a 2x12 stereo setup.
If you're the tinkering type, this item is worth every penny. Got so tired of removing the back off of one of my cabs, every time I wanted to try a different wiring scenario, or A/B speakers in my 2x12. This works flawlessly. Worth every bit of the time for the jigsaw project to make a hole to fit it. Great item and a great price.
Great until I tried mono connector and faulty- twist board and works.
Top product and service!!!!
First off the prices perfect second of all plug and play they're not kidding it went in real quick real easy real simple had to find some basic wiring diagrams online but other than that it works like it should The Price is Right outstanding product and thank you guys very much awesome will do business again
I’ve installed this product on 2 different 2x12 cabs. Great instructions, and easy to do if you are relatively comfortable with a jig saw. They work as advertised!
