I recently purchased a code 100h.  I've noticed that with the cabinet simulation turned off, the amp is incredibly fizzy and bright.  I am running into a 2x12 with Celestion Vintage 30s.  Is there a way to tame this high-end shrillness without having to resort to running cabinet simulation through an existing cabinet?

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.

Can you please show me which jack i should use to plug my head into the cabinet. I have a new 2 weeks old, Marshall DSL 20 HR Head with the MX212RR Marshall cab. 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

If I change to an 8 ohm V-series speaker in my DSL40CR, do you foresee any problems using it with an 8 ohm MX212AR cabinet , if I plug into the two 8 ohm speaker outputs ? .......................thanks............RD

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

Hello everyone, I own the Marshall CODE 100H and CODE 212 cabinet.I really love this amp, but I find the MY GATEWAY web page interface to be somewhat awkward to use. The following are issues that I would like to see changed.

1) On the My GATEWAY web page, the preset list at the top is arranged by columns (as it should be), but the MY LIBRARY list below that is arranged by rows.

?

2) There is no indication in the MY LIBRARY section on the MY GATEWAY tab whether a preset is or isn’t in the MY GATEWAY list.

Greetings,

What is the measurement AT THE TOP of the MX212AR vertical cabinet FROM FRONT TO BACK ?

Thank You................RD

Hello everyone from Portugal,

I have an Origin 20c Amplifier that I purchased new last year. It must have been old stock because it appears the manufacture date was 2018. I believe this unit has the faulty Jack wiring since the labels for the external speakers do not match the owners manual (2 8ohm jacks, without the line indicating 16ohm for both). My question is, will this unit work with a single Origin 212 cabinet, assuming I unplug the internal speaker, or do I need to get it repaired. If it will work, which of the speaker jack should I use, the one in the middle or the one furthest from the 16 ohm Jack

Hi! I have a question about CODE 100H. I need to play directly in mixer but it hasn't a DI exit, can I use it without a cabinet? If I can, how can I do it? If I don't use cabinet, will CODE be damaged? Thanks for your help. 

I have a Marshall Origin 50H, its about 7 months old and I've used it perhaps  maybe 10 times total for some pretty low volume playing and never used on anything but the lowest 5w setting. I'm using it with a proper 16 ohm Celestion cabinet and proper cables and playing for about 40yrs so know what I'm doing, well, most days that is lol! :)

Anywho,  after about 10 minutes the volume drops WAY off and I'm assuming its a power tube since the level of gain doesn't change at all,  just the volume and it gets real compressed. 

Since I've only had the amp 7 months, would the tubes be covered under warranty in any way? I would hope so due to how little I've used it, thanks for any insight.

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? 

Is it possible to combine Code 100w with MG412AG extension cabinet and have all 6 speakers work?

Hello,

I have an old Valvestate VS100R (Combo). I am looking to add an ext. cabinet to it 4x12'' (or 2x12'' at least).

Want can be the best model ?

Do I can connect the amp speaker (1x12'') and a cabinet ?

Thanks

Can I use headphones plugged into the DI port in lieu of a cabinet? Thanks

Does Marshall sell amp amd cabinet covers for their current products?

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

every company who sells digital amp made some upgrade with more amp or efx or cabinet or upgrade a better firmware with better tones. you do nothing! I've asked you - almost one year ago -, by mail, if marshall was programming an upgrade and in your mail you answered yes..I think was untrue, it's the worst support I've ever seen in digital amplification.
