Dear Marshall team:

I use the Code 25 amplifier, with the Gateway app and the Code series footswitch. The firmware is updated with the latest version available.

For a long time I have been noticing certain problems, mainly:

-The preset settings are changed on their own (sometimes the volume, other times the gain...) They are usually changed to the settings on the control knobs. I load the preset again, and after a while some of the settings are changed again.

-Another problem is that after using a preset for a while, when changing to another it does not change (it stays blocked). It does not respond either by using the pedal or by changing the preset from the app I have to turn off the amp. At first I thought it would be a Bluetooth problem, since I was using the Gateway application, with an iPhone. But now I'm using it with an Android phone and I continue to have the same problems.

Waiting for your comments, receive a cordial greeting.

Eduardo,

Hello users of Marshall ,

I bought my Moitor Bluetooth early 2020, I used it perfectly with no issues until last month (June 2023). 

My headphone turns on and connect to my Iphone, however whenever a take it off  or move a little bit the bluetooth connection cuts and my Marsahll disconnects automatically.  For information, my Marsahll felt down some weeks ago. 

Have you met with this issue ? How can I resolve this issue ?

Thank in advance for your help ! 

Hi,

I've just received my Code 25 amp today. It sounds good but I cannot pair it with my iPhone

It appears as "Headphones" in the bluetooth settings. When tapping on it, my iPhone says "Pairing failed "Headphones" is not supported". 

I've tried with 4 different iPhones (all up-to-date) and got 4 times the same trouble

I've successfully updated the firmware of my amp (MCU 1.47 / BT: V3.2) but it did not fix the issue.

Can someone help ??

Thanks !

A lot of people post this question of sound just disappearing after e.g. 3 minutes of play, while lights are still on, the LCD panel is on, headphones still work. I've taken my amp to the repair shop (no official one in Slovenia) and they sad they corrected a couple of bad solderings. But that actually didn't solve it. They claimed they have played radio on it for 3 days without problem. Although I put in my guitar and the same thing happens again.

So then I swithched off the bluetooth connection with my iphone and voila, the amp sound no longer dies after 3 minutes. I am not sure where the problem is but I hope that you haven't yet thrown the amp in the garbage bin. 

Quelqu'un pourrait il m'aider s'il vous plaît je n'arrive pas à connecter mon ampli code 50 sur l'application Marshall gateway il me met ce message: CONNECTION REJECTED You may only control amps you are already connected to for audio output.

Je précise je suis sur iPhone 13 dernière version d'iOS.  Le téléphone lui se connecte sans problème à l'ampli je peux joué de la musique mais c'est tout 

j'ai au préalablement supprimer et réinstallé l'application gateway, reset l'ampli, mis à jour le firmware de l'ampli, déconnecté l'ampli du téléphone et oublier l'appareil Bluetooth, essayer sur un autre iPhone (7)... bref je suis perdu du coup je ne peut en aucun cas faire mes préset depuis mon téléphone et c'est frustrant enfin bref si quelqu'un a une solution miracle je suis preneur et merci d'avance 👌💪

I've been through the forums tried everything. bluetooth is on. iphone says connected. marshall gateway app says its not. Youv'e wasted my time. my money and patience. GET IT SORTED!!!!

This issue is driving me crazy. My Code 50 used to work with my iphone and ipad, now it refuses to connect and I always get the above message.

I have performed the following:

1. Forgot bluetooth connection on both devices

2. Deleted iphone app and re-installed.

3. Re-paired and tried to connect with same issues,

4. Formed factor preset of amp with no luck.

I know the blueotth connects as I can play music through my amp from phone, I just cannot connect to update any presets.

Any solutions would be greatfully received, am getting so frustrated with this product.

I recently got a new iPadPro.  I can Bluetooth to my Code25, but when I open the MyMarshall app I get the following:  "Context 3D not available!  Possible reasons:  wrong renderMode or missing device support."  What does that mean and how do I get the app to open?  I deleted the app and reinstalled and have powered the 25 down and restarted.

I just bought the code 25, and only had it for a few days.  It was great on my iPad for effects via bluetooth, although after  I updated the firware it wont connect to thre app on my ipad anymore, it plays songs from my itunes app but the Gateway app says Im already connected and nothing works to adjust the affects. Im really bummed about this, any word on why this is happening and how to fix it?. 

Hi, 

I've just recently bought the Acton II to have as a speaker in our bathroom. Looks great and sound good enough. So far I'm satisfied. 
However, the speaker is driving me mad. Here's why. 
My girlfriend and I both use the speaker whenever we're spending time in the bathroom, so both our phones have been connected to the speaker at some point. 
But, if I'm playing music from my iPhone to the speaker and my girlfriend is in another room, let's say, watching YouTube on her iPhone things get wierd. If she adjusts the volume on here phone it also messes with my music in the bathroom. 

Another example:

Playing music from phone 1 to Acton II. then, Adjusting the volume by using the buttons on the side of iPhone 1 also adjusts the main volume of phone 2. Even though Phone 2 isn't in use. It just messes with the volume of it. 

This is suuuuuper annoying. Since the app is no where near of being good, I don't know how this can be solved. If there's no good solution I'm gonna have to sell the speaker and buy a brand that really knows how to make speakers for this purpose. 

Does anyone know if this can be fixed..??

thanks / Mathias 

Hello -  After really enjoying the Kilburn II speaker, I bought two Acton II speakers to couple them for ambiant sound when not using traditional speakers since you can't couple Marshall's wireless speakers. The Acton II is fantastic for sound and range individually *before* my attempt to couple them. I've had many complex compatibility issues with products over the years, but in this case, it's most puzzling why two same-model "coupled" speakers can be controlled via the iPhone/iPad I paired with them, as well as with the Marshall app (volume/sound settings) but cannot in any shape or form maintain simultaneous outputs even when they're placed right next to each other (well within the 10-meter Marshall spec). So before returning them back to store, I wanted to check with other customers if they've ever truly achieved the goal of coupling two Acton II's with both of them continuously and consistently playing in tandem without streaming drops. Thank you for letting me know,

What I've tried to so far:

- Followed Marshall's pairing/coupling intructions word-by-word. Though their instructions are incomplete and way below their reputation. 

What's more disappointing is the prompt you get in the app to "stay connected to Acton II but disconnected from Acton II in Bluetooth settings." Anyone know what that means? 

- Tried two iPhones and an iPad (all latest iOS).

- Deleted, rebooted, and re-installed the Marshall Bluetooth app (v1.3.1) for iOS.

- Moved the speakers next to each other to eliminate distance argument.

- Tested each speaker with direct Bluetooth to iPhone/iPad source without any issues. In fact, range is so much more when not using the Marshall app to stream to the speaker.

- Factory-reset the speakers.

- End result: The only way I was able to have them coupled was ignore their instructions, couple the speakers and then completlely shut down their app. after they show as coupled . However, there's no way for them to continuously and play in tandem (even sitting right next to each other with source iPhone/iPad next to them). They continue to switch between each other. 

- Also, Marshall needs to be clear that a "couple" can only function with one lifetime source. As soon as you try to use the speaker "couple" on another source device, you lose everything on the previous device and need to de-couple, forget speakers, re-add speakers to your device's Bluetooth, and then pray that the Marshall app will allow you to couple them again. Most of the 18-20 times I tried the whole process, I needed to uninstall their app, reboot device, and re-install their app. :(

Any help deeply appreciated before I return these speakers.

Hi there, just purchaced a Code 50, installed the Gateway app for iPad. All working a treat, eccept that if I am connected to the Amp via bluetooth, I am getting all the keypad sounds through the amp, also incoming messages, email notifications and phone calls. is there a way of stopping this????

Hello. I recently bout the CODE 50 and it's great, but the gateway is pretty much useless for me. I have tried pretty much everything and it still will not connect to my iPhone 11 pro max. I have had friends try the app and it works fine on their phone, but when it comes to mine, nothing! Really love the amp and would like the bluetooth to work from my phone so i can adjust with ease. Not the end of the world, but it is advertised that you can control everything from your phone so that's what i would like to do. Any solutions? Thanks.

Update to below- The iPhone 11 IOS 15.02 update fixed my issues. The app is working properly now & I'm very happy.
____________________________________________________I had a fault code & couldn't connect Gateway to my Code 50 a few months ago when I purchased it. I tried deleting the app to reload but when I reloaded, it was only accessible via the App Store & wouldn't appear on my Home Screen. I could connect for awhile. Recently it seems since the IOS 15 update to my phone, it no longer connects manually or automatically to my Code 50. The app is useless to me. I've search for an alternate app from another source that is compatible with the Code 50 but there doesn't appear to be one. The Gateway app and Bluetooth connectivity heavily influenced my purchase decision. If I had known the app was useless and I would have to physically go to the amp and try to dial in each sound, I would have just bought a fender. I really feel you should take my amp back if you can't correct the problem. 

Bought a marshall acton II today and I'm unable to play music from my phone on it. It does not show on airplay either while connected on app. I suspect it's broken on ios15. Hope it gets fixed soon or Im requesting a refund as right now it's just standing as decoration. 

Hi everyone.

Since iOS does not support AptX I was curious what codec is used when I connect my iphone (12 pro) to my Stanmore. 

Turns out it uses SBC. By any mean it is not the end of the world, tho now I'm wondering if I have a malfuctioning BT module. 

Hi!
Just bought a Marshall emberton. I did connect the speaker to my iPhone (iOS 14.7.1). It starts playing but after 10 or 15 seconds it loses the connection and the bluetooth lighy on the speaker starts flashing.

Can you help me, please?

Thank you!

My new Code 50 Amp won't connect to my iPad. They are paired via Bluetooth, and Gateway detects the amp. When it tries to connect, it perpetually displays 'Connecting........'

What am I missing?

Dear All,

I have recently received the Marshall Acton 2 speaker which has a very good sound and design!

However it works only on my IOS phone, under Windows 10, I can pair the device but get's a message of battery low and cannot choose it as speaker.

Any tip or help?

I reset the bluetooth already a few times

I have successfully saved presets to my iPhone and can play them using the bluetooth pairing.

What is the best way to permanently transfer or sync them from the iPhone to my Code 50 amp?
