Jack Plate - Plug and Play, Mono / Stereo
The Plug and Play eliminates the confusing switch found on most stereo cabinets. Just pick your impedance and plug in. Label is set at the common 4 / 16 Ohm Mono and 8 Ohm Stereo. Ready to install with a steel dish, wires, and speaker connectors. Direct replacement for many existing small jack dishes. Can be used for the following configurations:
- 4 ohm mono
- 8 ohm left + 8 ohm right stereo
- 8 ohm left only mono
- 8 ohm right only mono
- 16 ohm mono
The Plug and Play can be used with two 8 ohm speakers, four 4 ohm speakers, or four 16 ohm speakers. Please see Specifications, Files, and Documents for all recommended wiring configurations.

3 answers I have mulled over the schematics here on the website. Am I correct in my determination that to allow for optimisation of this jack as a plug and play (whether it be a 2x or 4x cab), I should use 16 ohm speakers? In other words, to be able to run a 2x at either 4 mono, 8 mono, 8 stereo, or 16 mono, I should use 16 ohm speakers? I'm attempting to build a 2x cab and 4x cab each of which I would like to be able to run at any of the above listed settings. Thank you soooooo much in advance for ANY help on the matter!

Yes, 4 16 ohm speakers are optimal for the plug n, play for everything to match up in terms of how the inputs are labeled. Also two 8ohm will work or 4 4ohm speakers.
I am using four 8 ohm speakers for a 2/4/8 ohm setup. each Speaker Pairs are wired in parallel.
2 answers I have a 2x12 both speakers 8 ohm. I don't get how the left out can be 8ohm and 4. If I only want to use the left speaker at will that jack be 8 or 4? Essentially I'd like to use one speaker at a time at 8ohms or both in series at 16 or two amps one to each speaker at 8ohms.
Asked by Anonymous on April 20th, 2018.
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.
It appears you can run a single speaker at 8 ohms by plugging a dummy into the other jack. It's right in the schematic.
1 answers I just bought this as a replacement jack plate for my guitar cabinet. I have one 16 ohm speaker. I'm assuming I put the speaker cable from my guitar head into the 16 ohm mono Jack. Which wires do I use? The unit comes with 4, red, black, white and green. I'll be coming out of the 16 ohm output of my guitar head. Thanks for any help you can give me.
Asked by Anonymous on August 26th, 2015.
As shown by the documents available above, the Plug and Play is designed for two or more speakers. A single 16 ohm speaker would use a standard mono jack wired directly.
1 answers Do i have to buy stereo jacks to run the cab in 8Ω left + 8Ω right or may i use two mono jacks ? Is it a mono jack needed for the 16Ω mono output ?
Asked by Anonymous on November 22nd, 2015.
You would use standard speaker cables for all connections from the amp to the plug and play. Two cables would be needed for stereo operation.
1 answers i have 2 16 ohm speakers what is the best way to wire this jack
Asked by Anonymous on February 9th, 2016.
You could wire it according to the wiring diagrams which are provided but the labeling on the jack would not match.
1 answers Can this jack plate be used for 16ohm left+16ohm right,and the mono at 8ohms? If so does it come with this customizable label?
Asked by Anonymous on February 9th, 2016.
It could be used that way but would not include a custom label so the impedance markings would be incorrect.
1 answers For 2 16ohm speakers, based on this plate, what would be the impedance for the mono jacks? Also, how long are the speaker connector wires that are included with the jack plate?
Asked by Anonymous on April 27th, 2016.
With two 16 ohm speakers the writing on the plate wouldn't match giving you 16ohm l+r and an 8 ohm mono. The length of the leads is 18"
1 answers I have a 8ohm and 16 ohm output amp head can I used two 8 ohm speakers for the plug-and-play and does it work and how do I wire it up

1 answers Silly question, but how would I wire up just a single speaker using this? I built a little 1x12 extension cab a while back and ordered a Plug and Play with the thought that I would eventually build a 2x12 that would replace it. Not sure which wires connect to which inputs and what to do with the wires not connected to the speaker. Thanks and cheers.
Asked by Anonymous on June 1st, 2017.
You can use the red and black wire and this should operate in mono at the designated ohms on the back of your speaker. You would only use the upper left handed jack.
1 answers How can I wire up a 6x12 (all 8 ohm) to this?
Asked by Anonymous on June 22nd, 2017.
This is designed for either a 2 or 4 speaker setup. We would not be able to advise you on setting this up outside of those configurations.
1 answers Forgive my non-tech savvy... I have a 3 speaker application (2x12, 1x15). Currently they're all 8Ω. But if I replace the the 2x12s with 16Ω speakers and wire them parallel, then introduce them to your plate, won't the switch see an 8Ω load from the 2x12s and an 8Ω load from the 1x15? I see a response above requiring only a 2 or 4 speaker application, and I reviewed your .pdf regarding speaker examples... but in the examples there are only 4 total contact points for 2 speaker arrays (+ & - x 2). Although I don't understand what goes on in your jack plate circuit, can't I use 2x 16Ω speakers parallel and 1x 8Ω speaker and achieve stereo? If not, can you recommend proper Ω for a 2x12 and 1x15 config?
Asked by Anonymous on August 5th, 2017.
1 answers To help everyone here and myself: is this circuit nothing more than the equivalent of 1/4" jacks with multiple contacts that make or break circuits? In other words, your circuit has no load, does not affect a load, it only provides a pathway (connectivity) from the 1/4" plug that is inserted, to the speaker terminals. Correct?

1 answers I have a 4x12 cab.All speakers 8ohm. I want to run top 2x12 as 1 cab. And bottom 2x12 as one cab. What I want to do is run mono 4ohm and mono 16ohm. Dont want to use it for stereo. Then for the bottom 2x12 section of my cab run 4ohm mono 16 ohm mono with 2 separate plates. Can I do this with these. Run 1 mono series and 1 mono parralel?
Asked by Anonymous on May 23rd, 2018.
This jack allows the following combinations: 4 ohm mono, 8 ohm left + 8 ohm right stereo, 8 ohm left only mono, 8 ohm right only mono, 16 ohm mono.
1 answers To run JUST one side at 8 ohms a dummy plug must be used in the other 8 ohm side?
Asked by Anonymous on June 2nd, 2018.
Yes that is correct. Simply place a spare 1/4" jack into one of the 8ohm jacks to get 8ohms mono.
1 answers I have two 8 ohm speakers that I’m trying to wire in parallel for 4ohms. All wires are connected as the diagram says in the schematics. Do I have to add additional wires to connect these in parallel?
Asked by Anonymous on June 11th, 2018.
If you have two 8 ohm speakers and you place the black and red wire on one speaker and the white and green wire on the other speaker you will get: 4 ohm mono, 8 ohm left + 8 ohm right stereo, 8 ohm left only mono, 8 ohm right only mono, 16 ohm mono.
1 answers Bought a 2x12 cab that has this jack in it. Both speakers are green beret 16ohm. When it’s wired as shown in the document here what ohm am I getting out of each jack. It’s confusing. Any help is appreciated
Asked by Anonymous on July 2nd, 2018.
Assuming the person you got this from wired it correctly you would get the following: 8 ohm mono, 16 ohm left + 16 ohm right stereo, 16 ohm left only mono, 16 ohm right only mono, 32 ohm mono.
1 answers In the diagram when it says, for instance, "four 16 ohm speakers"...does that mean "wire this way to get 16 ohms" or "wire this way if your speakers are 16 ohms" ?
Asked by Anonymous on September 5th, 2018.
The diagram shows how to wire four 16 Ohm speakers. So "Wire this way if your speakers are 16 Ohms" is accurate.
1 answers If I'm running 2x 4x12 cabs @16ohms each, my amp is seeing 8ohms parallel, would I connect the power to 16ohms on the plug and play to achieve this?

1 answers When you’re plugged into both inputs for stereo, are the jacks isolated from one another, or donthey share a common ground? I want to run two amps stereo with this jack plate; safe, or no?
Asked by Anonymous on June 19th, 2019.
The two inputs are isolated from one another. Running two amps in stereo is safe with this jack plate.
1 answers Hey, using this Jack with 2 16 ohm speakers would make the left 16ohms the right 16ohms and the mono jack 32 ohms?
Asked by Anonymous on January 20th, 2020.
Using 2x 16 ohm speakers the labels on the plate wouldn't match the wiring but would double the mono value to 32 ohms.
1 answers How can I use either spkr alone? I have a 2x12 cab, both 8ohms but different flavors (Anerican vs. British).
Asked by Anonymous on April 14th, 2020.
Simply plug your amp into whichever speaker (left or right) that you wish you use and plug a dummy cable (a cable not plugged into anything on the other end) into the unused speaker jack. This will isolate whatever speaker is plugged into the amp.
1 answers I have 4 4ohm speakers in a cab. If I use the 4 speaker wiring diagram can I use both the 4 ohm settings and the 16 ohm settings in mono and also the stereo option?
Asked by Anonymous on June 3rd, 2020.
If you have a 4 speaker cab with 4 Ohm speakers in it and wire it as shown in the 4x4 Ohm diagram, you will have the options shown on the plate. Those being 4 and 16 Ohm mono (Top left and bottom jack) and the option to run two 8 Ohm loads in stereo. The terms stereo and mono have nothing to do with the number of speakers being used, rather how many amps are plugged into the cab at one time.
1 answers I have a cab with a 12 and 15. The ohm gage read 12.6 which leads me to believe that I have an 8 and 16 ohm speaker. I can adjust the ohms on my amp head. Will the jack work? Any suggestions? Thanks much!
Asked by Anonymous on July 21st, 2020.
This is designed for two eight Ohm speakers, four sixteen Ohm speakers, or four four Ohm speakers. Mixing an 8 and a 16 Ohm speaker is not suggested.
1 answers Is there a maximum Wattage of speaker rating and or amplifier output that this unit can cope with ?
Asked by Anonymous on August 4th, 2020.
The traces on the PCB are pretty heavy duty, so this should handle most anything in the guitar amp wattage territory (<200W) but may not be ideal for some pro audio applications where you are dealing with high wattages.
1 answers the information say //4 ohm mono //8 ohm left + 8 ohm right stereo ///8 ohm left only mono //8 ohm right only momo //16 ohm mono //// but en the left side 4 ohm share the same jack with the 8 ohm left /// so can i use the same jack for 4 ohm and 8 ohm ?? i'm going to use two 8 ohm speakers // greetings
Asked by Anonymous on August 19th, 2020.
That is the concept behind this jack plate. When plugging a cable into the top left jack while nothing is plugged in to the top right jack, it will read 4 Ohms. If a second cable is plugged into the top right jack (regardless if the other end of that cable is plugged into anything) it will read 8 Ohms. The switching is done by the connections being made and broken by the PCB inside the plate.
1 answers No schematic came with the part. I will be using 4 16 ohm speakers. Am I to assume the schematic on the part site is to be used? Connect the colored wires to the noted location then make all other wiring connections for th 4 12 speakers I have

1 answers So u cant use the plate with say 2 16 ohms speakers in parallel which would be a 8 ohm load then? If not why would that been part of the option to. Thanks Dwayne
Asked by Anonymous on May 18th, 2021.
This is a passive jack plate, and there isn't anything preventing one from using this plate with a cab that has two 16Ω speakers, but the labels on the plate will no longer be accurate.
1 answers Is this H-700 Mono/Stereo Jack Plate safe to use with two tube amp heads plugged into the different stereo inputs at the same time? Each tube amp head would be driving its side of the stereo speaker split. Is each tube amps' speaker output ground connection isolated from the other tube amp (or does that even matter)? Thanks.
Asked by Anonymous on July 24th, 2021.
According to the manufacturer, the amp/speaker cab setup you described is the intended purpose of this jack plate, so yes, you should be able to use two amp heads in stereo using the top two inputs. That being said, we do not have any information from the manufacturer that describes in detail what is happening to the ground connections, so we can't comment on that.
1 answers Interested in this Jack Plate mono/stereo to replace an older DPDT switch-based plate on a B-52 4x12 cab with four 16ohm speakers. The diagram on your site for wiring four 16ohm speakers makes sense in terms of the stereo option. However, I am not seeing how using either mono jack will play all four speakers at the same time. What am I missing here? Thanks! -Ken
Asked by Anonymous on March 8th, 2022.
The PCB make or breaks connections based on which jacks are being used. In the case of the 4Ω option, it runs all four as parallel wiring, and the 16Ω will run as series/parallel.
1 answers Howdy I have marshall 1960 TV cab with 4x12 16 ohm 25w greenback which I need to get it to 4 or 8 ohms so does this switch do this without changing the current wiring to the speakers so really a plug and play or does all the wiring need changing for this to happen. Many Thanks
Asked by Anonymous on April 13th, 2022.
You would need to wire your cab using the x4 16Ω speaker diagram. If your cab is not currently wired that way, you would need to rewire it.

I loved how easy this product was to install and to use. One caveat was that the right 8 ohm tap engaged the 8 ohm stereo feature. In comparison, on a Marshall 1960, you can run either side in 8 ohms, but with this jack plate, you can only run the right side on its own, and cannot run the left side on its own.
Three star rating for the 16 ohm tap failing after 2.5 years of use. I used this in a 2x12 Avatar cab about once a week on average during this time. So that's like 130 times plugging in to it. It went to about 5 gigs during that time. I swapped speakers once during this time.
Despite all that, if you only play at home, or where you have spare cabs, it's a great product. This is especially if you have some 4 ohm and 16 ohm heads or if you run two 8 ohm loads in stereo. I don't trust this for gigs any more.
It works, but for how long?
I bought one of these for my speaker cabinet, so I could use different heads with one cabinet. A few months later the 16 ohm option failed. The jacks are proprietary and soldered to a PC board. Rather than tp replace the jack I bought a new unit for $20 plus shipping. I'm hoping for better luck with this one, but who knows? At least I have some parts to scavenge in case this one fails.
There's no guesswork with this jackplate - it adds a lot of versatility to your cab and is pretty difficult to mess up. The leads aren't terribly long so be careful how you orient your speaker leads. As always, AES is a pleasure to work with.
Easy and fast to hook up. Works like a charm and way sturdier than the crap that M**shall uses
Great Product. I use it on a Fender Bandmaster Cabinet set up with 1x12 8 ohm and 1x15 8 ohm.
This jack plate works great! My 2x12 cabinet now has a lot more flexibility.
These things are the $#!+! I love the Plug and Play jack. Takea all thw guess work outta hooking up my head to my 212 cabs. I bought two and installed them on both of my 212 cabs. No switches to fiddle with and try and figure out what’s for stereo, and what’s 4 or 16 ohm. It’s as easy as plugging into the correctly rated jack. Done! Highly recommended to anyone who makes speaker changes or just wants ease of use. 4 different colored wires for hooking to your speakers, so no mistakes can be made if you can follow the simple color coded scheme.
Easy to wire! Instructions are clear. Works great!?
Great product, does what it says it does, works fine, priced right - what more could you ask?
Excellent product! Easy to install and works like a champ. Allows me to use any of my heads with one cabinet. I have two 2X12 cabs with this installed already and will be purchasing a third jack plate for my 4X12. Really does make your cabinet far more versatile and I have noticed zero degradation in sound quality.
