Hello all. I am sorry for what is about to be a redudant and maybe to some, stupid question. I just got my dream amp, the JVM 410h. This is also my first tube amp and I want to care for it for long term use. For silent recording, I am running the line out with an xlr cable from my JVM head to my Scarlett interface, which I connect to my DAW and use cab modelling their for recroding. Do I lieave my standby switch on or off? The STANDBY/ silent recording notation is a little confusing to me. So should switch be pushed up or down? Also, should master volume be set to 0? Thanks in advance

I seem to be having the same issues that a lot of people have reported, where I cannot get the Marshall Gateway app to connect to my Code 25. I've only had the amp for about a week and I cannot get the app to see it. ? 

I can connect to the amp via Bluetooth using my phone (Samsung S10, Android 11) and whilst connected, can use it as a BT speaker to play music from Spotify. However, nothing I do seems to get the app to connect to the amplifier. 

-I've updated the amp to the latest firmware using my laptop/web browser. 
-I've followed all the instructions in the Bluetooth Connectivity Troubleshooter to the letter (CODE - Gateway Bluetooth Connection Troubleshooting - my.marshall.com)

No matter what I do, or what order I install/uninstall/connect, the app will not see the amplifier. Everything works otherwise - I'm able to apply Patches from ? using a USB connection - and the amp sounds great. I'd just like to be able to control it from my phone.

My Code 50 Makes a weird Hissing/Crackling sound when I am using the USB Input on the amp and using it in Reaper, Can anyone please help?

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.

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

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!

Hello when I attempt to connect my Code 25 for a firmware update the device is not recognized. It says USB malfunction. I read a post that says I must use a midi compatible cable. Is there a particular way to identify if the cable is compatible or not. If I search the cables I find do not seem to have the proper connector. Thanks

When I use my marshall on the pc I get really strong buzzing when recording and hearing.

I tryed 3 different cables, and updated the firmware 3 times already.

I'm out of options, this turned to be a nightmare to me.

I borrowed a friend's mini USB cable a couple months ago to plug my CODE25 into my laptop and it worked just fine. I got a new cable today and tried plugging my amp into my laptop and the following notice popped up;

If anyone has any idea if it's a cable, laptop or amp issue, I'd appreciate the help. Thanks in advance.

I got a CODE100H and the manual says that you never must run the amp without an cab connected. But there are so many videos and tutorials where the amp is plugged only via USB or headphones.  Does it make a difference if is there's a DAW, a cab or headphones connected?

And another problem is the delay while connected through USB. How can this be solved?

I had my marshall code for around half a year now and recently something has been going on with it. I use a Macbook Air with Logic Pro X and for some reason everytime I connect my CODE to Logic and try playing something, the second I touch the strings my Bass, Middle, Treble and Volume automatically go to 0.0. I have re-installed the Firmware and did a Factory reset and still nothing changed.

I recently picked up a CODE 100 amp and plugged it into my macbook to try to record using GarageBand. The program recognised the amp so I set both input and output to CODE and was not getting any sound, not even the metronome. Eventually after thinking about it I realized that output was set to CODE so I turned up my master volume (had it all the way down because I wanted to hear the laptop not the amp), and all of the sound including the metronome were coming through the amp speakers. Then I figured out that I could get audio out of the laptop by changing the output to Built in output. Now I am having the same issue on the iPad and can't figure it out. I have a Camera adapter that allows me to plug USB into the iPad. When I connect it, the iPad recognizes it and asks if I want to turn monitoring on, I do. All of the sound, previously recorded tracks, metronome all of it come through the amp speakers. I want the monitoring to output to the iPad speakers, but I cannot find the setting to accomplish such a thing. Any Help would be greatly appreciated, thanks.

Hello, I bought a Marshall Code 25 a few weeks back and it was working perfectly until I tried connecting it to a PC today using the USB port. The amp is just not showing up anywhere and the PC doesn't detect a new device either.

I've tried :

- Downloading the firmware update software (current version 1.44) to see if it would detect the amp (it did not)

- Using two different cables and two different PCs

- Restarting the amp and reconnecting the cable on both ends

Not sure what I'm doing wrong or what I should be doing next so help would be appreciated.

Hello!

I am using Marshall CODE as input/output audio interface with DAW software. I plug in headphones into Marshall CODE and It works fine, so I can hear sound from DAW. But at the same time I hear direct sound from CODE in my headphones.

I mean as a result I have double sound in my headphones: sound from DAW + direct sound from CODE.

Is it some way to turn off direct sound from CODE in headphones just to hear only sound from DAW (audio interface output)?

I connected the CODE to my PC using USB but I cant do anything in the Reaper DAW. Tell me the settings pls

Does anybody know how to do this?

I have just recently bought marshall code 25

I want to know what is the connection of the USB..

it is not a regular pendrive USB, mouse USB, Keyboard USB and etc,,,  i think its a difference connection on the amp

I have a xiaomi redmi note 8 and also have a problem connecting the marshall gateway app to the amp code50.
I can only be connected as if I were listening to music, I even tried to connect it with an otg adapter, it works like that, but there are a lot of problems with braking the application? Please if it is possible to solve this problem.

 And if I tried all variants except one, and that is to uninstall every marshall application to amplify my Marshall Code 50 Firmware 1.4.4 recognize bluetooth connection from which I can control my installed Gateway 1.5.5 of course not just music to listen to But that I have complete control and whether maybe the problem is that the usb is included in my computer, whether to turn it off because I registered everything else. If anyone can answer all these questions I will be grateful.

Hello everyone, I wanted to tell you about my situation and if you can provide me with any advice or help.

but now I tried to connect it with my pc to use it as an interface and I couldn't, becouse it dosen't appaers in my daw.
When I put the usb cable, the guitar did not sound in the amp and I assumed that because the sound would go to my pc, 
but when I took it out, my guitar did not sound,it does not pick up my guitar. 
I tried his bluethooth function and my amp plays the sound of my phone.
Maybe conect the cable usb make some mistake in the software, i don't
