Hi I have had this Marshall Code 100 for a few weeks now, mucking around with it to try and figure it out and finding it to be a little user unfriendly. What I want to do is to change a single preset to what it was originally (eg factory setting) without doing a factory reset and losing all my other changed presets. I cannot find any joy anywhere about this. Also, when I look at the list of 100 presets online (there are a few lists going around in chat forums and also in the gateway section of this website) I can only ever find the 100 presets that are on the phone gateway app and not the list that was originally on the amp (for example on my amp when I factory reset it, 00 is JTM Chill, 01 is "So American" etc, whereas my gateway library has 00 as EL34 Heaven and 01 as Plexi Classic). So I cannot find the actual standard amp preset list anywhere online or within the Gateway app.

My questions boil down to three:

1. How do I restore an individual preset to what it originally was (without performing a factory reset)? 

2. How do I even know what the original preset was called?

3. Say I connect my smartphone to the amp via gateway and bluetooth. If you click on the arrow on the right hand side of one of the presets in the library, it takes you to another screen. In that screen it has an amp section and a library section, with 2 small boxes you can tick next to each. What is the purpose of this screen and ticking the boxes? Like what can you actually change on this screen is it just the name of the preset or can you replace a preset that is on the amp with one that is in the gateway library?

Needless to say I am very confused and was hoping to be way ahead by this stage. Please help!

Does anybody know when Code firmware update is expected to be released?

Current version causes serious issues with Bluetooth reconnecion after the amp is swiched off.  Also Master Volume does not work evenly and my CODE 25 is definitely too loud for practising at home.

Hi all,

On Christmas of 2016 I was bestowed upon the mightiest of gifts. And I have enjoyed every second from that first pairing to yesterday's low battery hum.

I've arrived home from work and went to charge the headphones. To my surprise in the morning when I went to unplug them they weren't showin' off the silver/white light indicating they've charged. I tried to turn them on and they wouldn't. I then went on to again plug them in and the red light indicator showed up that they're charging. I left for work and when I got back the light was off again.

I unplugged them, tried them on and still nada.

Since then I've been trying different USB cables which work just fine on other devices and I got nothing. When I put in the 3,5 jack it plays beautifully, but I kinda need the bluetooth part for work, so I was wondering if anyone ever got that problem.

I've googled and googled and the only conclucion I've come to is that I need to have them repaired from the shop that my wife bought them from for me.

Unfortunately that would mean at least a month without them and I'm trying to discover any other possibilities before turning to that one.

Cheers in advance if anyone reads this.

You're my only hope, guys and gals, I guess.

I have purchased new Code 100 (a demo from Sweetwater)  I am not able to connect the amp to my personal device.  When I press the Rev and Power buttons to connect,  the blue lights flash,  the device number shows up on the amp but either of my devices (an I Pad and an I Phone) will not recognize the Code amp.  The Code Amp does not show up in the "My Devices" so it never has the opportunity to pair or show up as connected .   My phone and Iphone recognizes other bluetooth items, ie, head phones, speakers etc. I have tried the FAQ suggestions and have tried the recommended fixes and I am still not able to connect.  

I have not done a firmware update on the Code 100.

Any assistance would be greatly appreciated.

Thank you,

Steve H.

It seems that my phone is connected via Bluetooth,

but on my iphone SE I do not see a connect block on the Gateway

only  a scan for amps block and this does not do anything.

So I bought a Marshall CODE 50 a bit ago, and with nearly device I've tried - there seems to be a lot of issues with getting the gateway app to connect to the amplifier in general (most of the time it doesn't work - despite pairing just fine). 

I've tried this on the Samsung Galaxy S8, iPad 5th generation, iPhone 7+ - The connection issues seem to stem from the apps use of Btle on these devices. 

To experiment, I built an application that connects to the amplifier via bluetooth for Windows, and issues commands to the amplifier through the PC. This application uses a "classic" (SPP /RFCOMM) socket connection to send commands. The application works perfectly fine via this means - it can be seen running below: 

As an experiment - is there a way to force the mobile applications (if it isn't using a btclassic / rfcomm connection) to use a btclassic connection as opposed to btle? 

Thanks and all the best,

Hello. I just bought a code 50, and been trying to connect the Bluetooth but it simply doesn´t work. No Code50 is found in the list.
I have a Sony Xperia L, with the newest Android version (7+), but i can´t download the Marshall Gateway App from the Play Store, cause it says it´s not compatible with my Android version. 

I´ve read the forums, and more people seem to have the same problem. Please FIX so i can try using the full potential of my amp...

Hi

Gateway does not work with my Android 4.4 phone. Does not even show the connect button for amp. Installed it directly to my phone 'cause Google Store says not compatible with my device. Did the "Fix" by remounting my SD and all steps but no luck.

Please assist with problem.

Regards

Hi, my Code 50 USB has stopped working, nothing wrong with the USB port because it still charges the phone - tried two cables, no luck.  So now I'm trying to figure out how to play songs through it via Bluetooth but *&^%%%%### no luck - how the hell do you do it? I've downloaded the Marshall Gateway app to my android but all i get is my phone icon and an arrow to the amp icon. DO I have to do something on the amp?

I need some help with the Bluetooth connectivity.  I hold down Reverb/Power on the amp turning on the Bluetooth feature and I tell Gateway to Scan for Amps and I get nothing.  My Iphone Bluetooth is on.

I'm using the USB connection from a PC to the Code 25, and found that the ouput sound on the headphones is only mono-left mixed.  I get sound in both speakers on my headset, but when I test left/right channels, it's obvious that the sound is only coming from left channel.

This isn't an issue when I'm playing music through the Bluetooth connection, and both left/right channels come through ok.

Is there a firmware fix so that when sound is channeled through USB to the headphone 3.5mm jack, it'd be stereo instead of mono-mixed?

I'm probably an idiot, but I can't make this work with the gateway app. I've paired and connected with bluetooth, I got my app open, pressed sync, but whenever I change something on the phone, nothing happens on the amp. Some videos show I have to go to preset, through the bottom left corner thing, to get into presets and turn the screen gold, but whenever I go there it says "Tap to sync" and when I do, nothing happens. please help. 

Hi, I am using CODE25.

I updated the firmware to V1.41 yesterday, but since the update, Bluetooth is no longer automatically connected.

There is no problem right after pairing Bluetooth according to the way suggested in troubleshooting.
However, after rebooting CODE25 not recognize the device again on the iPhone's Bluetooth settings.
So to use the Gateway app, I have to pair it with REV and Power each time
These problems have been seen since the firmware update and before that there was no problem at all.

I hope to know if there is a way to fix the Bluetooth connection problem or roll back to older firmware.

Thanks

My phone connects to the amp perfectly with Bluetooth, and can listen to my music etc.

But my gateway app cannot find my CODE amp. I've tried everything. deleted and reinstalled app. reset my amp.

Any help would be very much appreciated.

I phone 6 user here, latest software installed. Latest firmware installed in the CODE 50 as well. I can connect the amp and my phone via Bluetooth, but the Gateway app doesn’t even acknowledge my code to connect with it. I have tried everything I have seen in these forums from un-installing to re-installing to restarting, turning off and on. I really like this amp but this is pretty frustrating, it worked when I first got it but for some reason not anymore. Any fixes for this? 

Hello everyone,

my Acton shows a latency when connected via  Bluetooth to my Laptop. Youtube Videos arent lip-sync anymore.

My Killburn does not have this problem.

What can I do, if there is something that I can do and not Marshall?

No automatic bluetooth connection after firmware update.

Please solve this problem.

Or support firmware rollback!

Hello, there. First of all sorry for my bad english.

I got two CODE 25, and it cannot be automatically paired with my phone again if it was rebooted.

When it is turned on, the blue light does just keep off and never get reconnection process.

Both of these got this issue after firmware update, and factory reset and troble shooting guide does not help anything.

I tried every ways so many times but it was useless.

There are many users suffering from this issue just like me... it is really annoying even this amp is really good.

Please leave an advice. thank you.
