I have a two part question 🤔.  I have my two amplifiers listed above.  I have both electric and electric acoustic guitars.  I'm learning how to play and bought the 50 watt acoustic Amp as I  really like the sound of over wound humbuckers through it for heavy slow blues.

First question,  keeping the AS50D as the main sound, can I connect it through/to the 100 watt Marshall? Both are 4 ohms and I would like the maximum amount of power to drive my 4 x 12" cabinet of 8 ohm Jensen Tornadoes that are wired in series for the 4 ohm 100 watt MG HDFX. Then I would have 150 watts total to drive my 400 watt total limit.

 

Question two,  can I connect my 50 watt AS50D Amp to my 4 x 12" speaker cabinet by running a cable from the back of my Amp to the cabinet. I have footswitch,  line out and (effects loops) send and return Jack's to use.

  Even though my 4 x 12" cabinet would be very under powered. I would like to hear the sound of the AS50D  through those speakers. I'm new to guitar and don't want to ruin any of my equipment.  I did also have a guitar made through two luthiers,  I also made the 4 x 12" cabinet to match my guitar.  I call them Snort and the box.

  I have the components for the sound I'm looking for,  now I need to combine them all together.  I truly appreciate guidance from the technical support team at Marshall. 

God bless you for your time and kindness.  Thank you,  Eric Dailey

Hello,

I often play my origin 20h without the speaker connected, using the internal dummy load (no speaker cable connected).

My question is: can I leave the speaker cable connected to the origin, but NOT to the cab? Or thay it's going to deactivate the internal dummy load, as the cab was connected?

It would be easier for me that way, to occasionally use the cabinet without turning the head to reach the connector, but I ask because I don't want that to damage the amp.

Please let me know, thanks and regards

Has anyone used a small pedal amp to input the headphone to a amp like the electro harmonix 5MM.  I saw this done on a Spark amp to connect to a speaker cabinet.  I would think I could do the same on the CODE.  Adapt the 1/8 to 1/4 to go from headphone jack to the input on the 5MM and then in my case that speaker cable goes to a mixer.  I know this amp does have a dedicated line out to do what I want to do.  So I think this would accomplish the same thing.  Any thoughts good or bad?  I plan to try as soon as I get my hands on a small pedal(not a stomp box, just a pedal size amp) and configure the cables to go from 1/8 headphone to the 1/4 input on the amp.  I'm not an electrical engineer, I just need a "line out" if possible.  Should work.  Thanks,

Hello, I recently ordered a used JCM800 Model 1580 Bass Cabinet.  The seller's photos show it with one 18 inch Celestion G18Q-400 speaker.  I've learned that they were made in the 1980s-90s, and came in mutliple speaker configurations. Mine is the 1x18.  I'm assuming the cab originally came with the G18Q-400?

Would really love to know:

1. the performance specs of the G18Q speaker (Celestion.com didn't have any info)

2. whether the round port cut in the baffle of the cab is original. 

See picture below.  Thanks!

I have two identical Marshall DSL 100 watt heads. One of them was starting to crackle when I turned up volume on either clean or distortion channels. It  finally quit and assumed it was just dust in pod. However  a week ago turned amp head on and neither green light for clean channel or red light for distortion channel were coming on and no sound at all from either channel coming coming through speaker cabinet. Trying to get some help on what could possibly be wrong causing me to lose sound from amp head. Thanks

I noticed there is an emulated out on the back of the 20Watt Dsl head. From reading the .pdf manual, I understand that the head needs to stay connected to the speaker cabinet. So I know to never un-hook it, however - My questions being - 

Do I need to be in Stand-By mode to actually use the headphones? If not, will the sound still come from the speaker cab? 

Also, can I just plug my headphones directly into the Emulated Out? the .pdf manual says the Dsl20 Emulated Out supports Headphones. But I've seen people comment in other places that you need a headphone amp that increases volume or something. I haven't been able to test with headphones yet, and I kinda' wanna' get the right answer on this before I try. Thanks. 

 

Loving the Amp and Speaker cab though haha. Just came in yestreday.

I have 3 combo amps each with a single 16 ohm speaker. baffles the heck out of me why Marshall would recommend a 2x12 8 ohm ext cabinet. I want to run both the internal speaker and the ext cabinet at the same time. I would like to put 8 ohm speakers in the combos to match the ext cabs. I have a JCM 2000 DSL 401, a DSL 40cr And an Origin 1x10 20 Watt. Can a16ohm speaker be upgraded with an 8 ohm speaker in these combos and if so what speakers would you recommend. Any additional suggestions or information is most welcome.

On the back of the head it has 3 jacks for to plug into the cabinet and i dont know which is the best. It has lines pointing to the OHM's but the lines dont line up with the different ohms and its hard to tell which one to use. Anyway of sending me a picture or explaining which jack i should use please. Ive looked every where, youtube, online googled and cant find any info on which jack to use from thr back of the head to plug into the speaker cabinet. Thank you

I have read, when using the direct out there is no need to have a cabinet connected to the head.

My question is: is this in general or only when the direct out is engaged?

I would like to slave another amp from the effects send, without using a cabinet connect to the origin 50 head.

I wonder if the dummy loads is always on

WARNING: When using the DSL1HR head
for ‘silent’ practice or DI recording ALWAYS
disconnect the speaker cabinet from the
amplifier’s rear panel before switching on.
NEVER unplug the speaker cable from the
speaker cabinet while it is still connected
to the amplifier rear panel. This may stress
the amplifier’s power-stage and in extreme
cases may lead to valve and/or transformer
failure.

 

Can i use an emulated out with the cab speaker plugged in?

Hello,

can I use my JTM60 speaker with a Marshall Origin 20H Head?

Also, my JTM60 has suffered some damage when my nephew tried to power on the amplifier, she cranked everything up but didn't succed, when I got home I didn't noticed it was all cranked up and powered it, it blew tubes and some more, I had it repaired but it didn't get back to the same sound as before... I'd like to have it checked by qualified personnel, can you indicate someone in Italy, please?

Thanks a lot,

Marco

Hi,

 

Have a few questions about attenuator usage with SC20H amp.

 

1. Do I need two attenuators? My cabinet has two speakers (8 Ohm each), and SC20H has two separate outputs for each speaker, so does it mean I have to buy two attenuators, one for each speaker? I didn't manage to find SC20H schematics, so I'm not sure if those two amp outputs are connected in parallel internally, and I can just use one attenuator.

2. Do I need attenuator(s) at all? I want to run the amp with overdriven tubes, thus I have to set max level, right? Consultant at my local store told me it's enough to reduce "Master" volume, and EL34 will still be overdriven, if I set "Pre-amp" volume to max. But folks at Marshall forum say that it's still better to use attenuator, even in 5W mode. Again, I don't have SC20H schematic, so it's hard to tell who is right.

3. What if my cabinet only have one 4 Ohm input (2 x 8 Ohm speakers inside)? Is it enough to connect it to the amp with only one cable? Or I have to rework my cabinet to have two different inputs (separate input for each speaker)?

 

Thanks!

Hi, I just want to make sure I've got this straight. I want to run my amp through my external attenuator(weber mini mass) and then into an 8 ohm external cabinet.

1a) Amp (8 ohm out)->attenuator(set for 8 0hms)->to external cabinet(1x12 with 8 ohm speaker) Is this correct?

1b) In the above scenario, if I want to run through the 8 ohm cab alone do I have to disconnect the onboard 16 ohm speaker? 

2) If the external attenuator is not connected, can I run the amp through the 16 ohm combo speaker and the 8 ohm ext cab at the same time? Or is it either/or?

Thanks

Just bought a brand new Code 25 amp that was delivered by courier. It sounds great in play but there is a relatively loud constant hum from the speaker from about 5 seconds after switch on. Even with no guitar attached. is this normal?

 Also something is rattling inside when I tilt the cabinet side to side. I'm worried it may have been damaged in transit. Maybe these two issues are related?


Anyone have any thoughts or advice. Not sure I can face sending it back to the seller as although I bought it off a .co.uk website it actually shipped from Poland.

Hi, I am trying to find out any more about my JTM45 amp. I have owned this for over 45 years,  i have never made any changes to it.

Something that always puzzled me is the lack of any serial number on the rear panel.  I cant see why anyone would have made a new chassis, but there are extra unused holes and i can make out where someone has scratched on the type of valves  in each position. I am assuming its probably late 1963 as it doesnt have the 'coffin' lable but is a two tone cabinet as per the early kind. Also the knobs are different to others i have seen.

Also i can find no record of the model of speaker cabinet that i assume is also a Marshall cabinet, 2 x 12" speakers. Sadly the original Celestion speakers are long gone (my fault!)  I have seen one reference to an extension cabinet or boutique cabinet that looked similar, how ever it looks like the Marshall badge was at an angle on mine, though it was missing when I bought the cabinet.

Any help for the above would be great, many thanks, Martin

Hi Marshall team, my ORI20H says on the back 'CONNECT SPEAKERS BEFORE USE'.

So, is it wrong? I read in the forum that it has an internal dummy load, so that it can be also used without the speaker connected, for example putting in the Di/out: the headphone jack or a mono instrument cable to an audio interface/multitrack recorder/pa/mixer.

So, no need to connect the cabinet? IS IT SAFE?

Thanks and regards

Hi, Do someone know if the "custom voiced" speakers on a CODE 4x12 8ohm cabinet are the same as in the mg412a cabinet ? The mg cab is loaded with celestion g12-412mg 8ohm speakers that look like celestion rocket 50 but seem to be rated at 30 watts ... because the cab is rated 120w... some AVT cabs are loaded with celestion g12-412avt and some with celestion rocket 50 but AVT cabs are 16ohm (maybe the cause of suffixes change on the g12..) I've browsed  the celestion website to find some answer and the only one that had the same magnet is the rocket 50 and is rated to 50 watts... i would like to know what kind of speakers are on the CODE cab and if the mg412a cabinet sounds about the same as the CODE 412 cab with a CODE 100h head ...i don't like the format of the CODE cab...but want to keep all the tone modeling capabilities of the CODE 100w head
