Hello everyone from Portugal,

 
I hope you guys are safe and keeping up. Proud of another Marshall product, adding to the existing Haze 40 and the pre JMP-1, the CODE 100H. I am still going thru the details of every aspect of the digital architecture, but some do seem permanent and require your support:
 
1. Each saved preset will freeze the unit, muting sound, disabling "preset" knob, only mitigated by turning off and on the unit. Actually this will happen exactly the same way if I'm using the app to save the preset.
 
2. If by chance the app is not detecting/recognizing the amp (after previous sync's), the only way to enable this is to shut down the app and turn it back on again.
 
3. When the unit is ON and the volume is 0, there is a clear hum coming from the speakers. This hum is non existing when using the headphones. I am using the original cabinet cable supplied.
 
4. My understanding of the CAB feature, is that it should be "on", if using the DAW or headphones, and OFF when connected to a cabinet (I'm using CODE 212 btw and enjoying it). Why all the presets are factory saved with CAB "on"?
 
The unit was bought with the 1.44 version already installed. I have not tried yet to reinstall anything. I am using Mac, with no Windows sw.
Thanks for the support,
Pedro

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.

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.

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.

On the Gateway app I can playback very little music. I can easily play music with iTunes (Bluetooth) but I am referring to using the playback feature. I have tried to playback 50-60 songs, some of it is purchased but all of it is downloaded. Why do only certain songs work. This is a huge issue for me and one of the main reasons I bought the Code 100H and 212 cabinet.

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,

so now I know I can use my origin 20 head without any cabinet connected, taking the sound from the DI out. 

But my question is...can I use it with the master volume at 6-7 (1-2 o'clock), to get tube breakup point and creamy sound, like I usually do when the head is connected (through an attenuator) to the cabinet? 

Is it safe to crank the volume (max 6-7) when using just the internal dummy load? 

Please let me know, THANKS

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
