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.
December 16th, 2017
With (2) 16 ohm speakers what will the actual impedance be then? impedance
November 1st, 2018
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.

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?
January 18th, 2018
It does not sense anything since this is a passive circuit. The resulting ohmage is determined by the ohms of the speaker.
June 11th, 2020
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).

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.
March 30th, 2019
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?
April 2nd, 2019
Staff Member
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.
May 7th, 2019
Thank you so much for the quick and clear answer!
August 13th, 2019
This is a helpful question. Does the 4 ohm or 16 ohm jacks work as it is strictly a "pass through" jack at that point?

The two 8 Ohm jacks are the only two that can used simultaneously on the jack plate.

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.
February 3rd, 2017
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.
February 8th, 2017
Correct, but you can get two 8ohm loads from 4 16ohm speakers in stereo.

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?
May 26th, 2017
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.

Is this correct? I have a revv generator 120 and an avatar 2x12 cab with two 8 ohm speakers. The amplifier has 2 4ohm outputs, 2 8 ohm outputs, and 2 16 ohm outputs. Do I connect two separate speaker cables to the 2 8 ohm outputs of my amp and plug them into the 8 ohm stereo inputs of the cab?
August 14th, 2019

We can not say that this would be the case with your avatar cab if it doesn't have this plug and play jack plate on it. If it does and it is wired as shown in the speaker wiring diagram, yes, you would be able to do that.

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.
July 8th, 2018
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.

It doesn't sound like the amp and the cab are compatible as is. You may need to change the speakers in the cab (either x2 4 Ohm speakers in series or x2 16 Ohm speakers in parallel) or replace the transformer in your amp. What amp model is in question? I may be able to provide more info with an amp make and model.

If you were installing this on a x2 8Ohm speaker cab, absolutely no soldering would be required. If you are hooking this up to x4 16 Ohm or x4 4 Ohm speakers like shown in the other diagrams, our twisted pairs of speaker connector wires can be quite handy to eliminate the need to solder. https://www.amplifiedparts.com/products/speaker-connectors-twisted-wire-pair

Different amp models will have different switching mechanisms in them and the answer to your question is dependent on that, not anything that this jack plate is doing. The jack will be 8 Ohms left and 8 Ohms right in stereo.

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.

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.
