hi there , 

    Is anyone else having the same issues downloading user presets from Marshall.com ? I have a code 25 and ive already installed the updated firmware , however im still having issues downloading the presents when i'm connected to my computer.

I recently purchased a Marshall SC20H, I have noticed that there is a lot of "noise" in the amp when the FX loop is engaged. The nature of the noise is broad band hiss, similar to white noise. I am wondering if there is something I can do to remedy this problem, or if this is a flaw in the unit.

Your advice would be much appreciated.

Thank You

I have downloaded app and it keeps saying not available ( the 3dx questions) I have deleted and nothing is working 

Hi,

New to the forum, and new to valve amps. I have just bought a Dsl20cr, and I've spent the last 40 mins on standby mode to allow the valves to warm up.

Unfortunately, I'm still not getting any sound out of the amp.

Any suggestions would be greatfully received.

Regards,

Karl

We have two Marshall Acton Multiroom that have the exact same issue. Whenever they have been plugged in the power for more than 24 hours the sound becomes distorted/crackles and it gets increasingly worse the longer the speaker is powered on.

The only solution we have found is to pull the power plug for a minute before plugging it back in. Then the speaker will play fine for another 24 hours before it starts to crackle again. However, this solution is very inconvenient.

We have reached out to the Marshall support but they are not much of a help.

Has anyone else found a solution to this issue?

I recently noticed on my marshall amp an additional audio jack port thats beside the port for the headphone jack that i use my headphones with, I wonder what it is used for does anyone have an answer? 

the amplifier in question is the marshall MG10G

Hi,

when will be the Marshall Code 100H (Head) available in stores in Germany again?

I'm wondering that it's not shown on Marshalls website anymore. Is it discontinued?

Kind regards,

Hello, everyone! I'm looking to buy a Marshall Code 25, and I've heard that plugging a bass guitar into a guitar amp can damage it, therefore I'm wondering if plugging a bass into the amp and recording it through the USB port will harm the guitar amp.

Hello Everyone, 

I bought the Marshall code 100 Head as a second hand after watching the positive reviews of it, and I really liked the sound and its features!

I plugged it to a 1 x 12 Cabinet and it works good except for my big disappointment with the hissing white noise that i was getting even when the master volume knob on the amp is turned all the way down. 

I tried every simple solution that i could come with, including turning off the computer in the room, I tried resetting the Amp to factory settings,  I even installed the new firmware from the marshall website.  but none solved this issue.
Does anyone know the solution for this problem? 

Thank you very much in advance

I have tried doing so but the problem I am having is there is about a half a second of audio delay while playing.  I didnt know if an additional audio interface would solve that issue or if the amp itself should handle the traffic well enough. It could also be possible that i need to re-orchestrate how i have all the cabling ran and how i have the audio being played through the amp. I simply have the guitar plugged into amp, amp plugged into pc with micro USB cable provided. I had all the output audio from the computer going to the amp.  The computer being used has over adequate specs to run everything needed.

Thanks for your assistance

I am the happy owner of the TSL60 JCM2000 amplifier. I am an electronics engineer. For me, the regulation process is very simple, only the correct value is important. I would like to check if the BIAS value is correct after several years of use. I also wanted to know this value in case of changing lamps for new ones. In this amplifier, only one potentiometer is used for adjustment. There are three control pins. Pins 1 and 3 give the same values. Pins 1 and 3 are shorted? What should be the correct voltage value between pins 1 and 2 as well as 2 and 3? 40mV or 80 mV?

Hello all, I have an older amp MG15CDR. Bit of a problem with it. Crackles when you turn the gain pot or the tone pot. Seems to be worse when just turned on.  Maybe it's the potentiometers need replacing? Anyone else had this problem?  I can't see that Marshall will supply just these parts.

I would like to repair it, as it is a great little amp, suits my needs well.

I have code 100 and I got (DigiTech Trio+) and I would like to know

how to connect them together properly 

I'm not sure if they work together or not???

When I connect the DI output of my new Origin 20c to my recording system (ART USB Dual Pre into Logic Pro on M1 iMac) there is a constant hum. A noise gate set to -30dB just cuts it out. The combo speaker itself is silent. I cannot find any help on the Marshall website!

Before I start playing with the amp, are the user created presets stored separately from the inbuilt ones? I've read through the manual and got the impression that if I save one that I have created then it will overwrite the last one I was using?

"Context3D not available! Possible reasons: wrong renderMode or missing device support" error message on iPhone 11. All I see when I open the app is a red bar with the error message in white letters.  Any idea how to fix this?

The reverb doesn't switch on and off... Is the footswitch specific to the amp? I purchased a 91004 as the amp didn't come with one when I purchased it. The gain button works...

Thanks, 

Johnny

PS. I saw this picture in a CL ad, which got me wondering

There are multiple phones that use the Emberton speaker in our house. When one phone is playing music through the speaker using Spotify and another person enters the room with their phone, the speaker will always switch to their phone. It could be anything such as a video from social media. It pauses whatever the first connected phone was playing, and interrupts any music playing. 

We also have an Acton speaker and have had no issues over the years. At first I thought it was a fault with the Emberton and have had it replaced under warranty. However, the new speaker is doing the exact same thing. 

Anyone else experiencing this and (hopefully) have a solution?

I have been experimenting with the DI out on my SC20H. In the manual it says it is an "emulated loudspeaker" output however it sounds terrible direct into my DAW. Once paired with a IR it sounds pretty good so I am wondering if this is an error in the manual or if it just sounds bad and should be avoided? 

Thanks!

Code  50 won't connect to blue tooth
