Hi, I need a little help,  I'm a newbie on this...

I know my code 50 doesn't have a "line out" but it features a headphone out, can I conncet the amp to a Yamaha mixer? I want to control my guitar volume with the mixer, plus a mic and an acoustic guitar.

If that is possible, how should I set the master volume, the preset volume and the gain in my marshall?

thnak you!

Today I tried to play my Marshall code 50 and noticed that there is acutally no sound coming through.
I already changed the cable to make sure that the cable is alright.
I also noticed that there is no Headphone sound and the amp tuner is not working neither. 
The speaker makes the normal light buzzing noise when turned on, so I assume that it is not about the speaker. 

I did a firmware update just now, but I didn't help. 
I really don't know what to do anymore. I barely played the amp and never transported it neither.
Why it is suddenly not working is a mystery to me. 

If you have any advice please let me know. 

Hey Marshall,

I visited the dealer recently and tried another CODE 25 amp in the shop with the same latest FW version.
The same bluetooth behavior was observed (as described in many threads here, for example this ).
If you insist that it's a HW problem - please make an official statement that CODE 25 amps with serial numbers XX-XX have faulty Bluetooth Modules and you would like to recall/replace it. I think you can easily check your production and make a quality check on this case.

I think there are only few ways forward:

-  a FW update with a fix, promised a long time ago. Is it really so hard to rollback a piece of code, revert some changes from the latest FW update? 

- official recall, so that we just return it and get a 100% working unit instead.

- make the firmware code open source, so that we could fix it ourselves and make further improvements.

Regards,
Ilya

Have any of you CODE amp owners found a good Robin Trower preset? Thanks.

Hi,

I recently purchased a Code 50 and have been trying to connect it to the gateway app on my Android phone. The phone connects to the amp successfully via bluetooth and I can stream the audio out to the amp directly using Spotify but when I go into the gateway app, it says "Not Connected". I tried the "Scan for Amps" button but it doesn't find anything. Any help is appreciated.

I researched 1x12 open back vs. closed back vs. ported cabinet guitar cabs. My experiment with my Code 50 amp was to remove the back without unplugging anything so I could here the difference between closed back and completely open back. The amp really came alive with a lot of punch and presence while ridding the boominess that occurs. I removed the power cord socket and cut a square the same size as the speaker. This was an improvement but I liked the complete open back sound better. I then cut the back out more leaving just enough stock to support the existing power cord socket hole and protect the electronics inside the cabinet. I will continue with cosmetics such as painting inside black and/or add a grate for protection. To my ears the amp really came to life open back. I will keep it this way. It is an easy experiment to try without sacrificing anything, just remove the back cover screws and pull the back away. If you hate it you just refasten it and leave it original.

Hi.

Just a warning (possibly more a bit of advice maybe):

I noticed over the weekend that sometimes (not always) when retrieving a patch from a CODE amp. the Marshall CODE PC Editor does not always get it right.  Sometimes it will load perfectly and other times it's almost as if it's retrieved some, not all, of the settings for the patch.  I only noticed this after retrieiving some presets, making a change or two, and then overwriting on the amp. with the incorrect settings and I thought I was going bonkers because I checked and re-checked what I was doing but whenever I saved on the amp. sometimes one or two of the parameters were not as I set them.  It seems to do the same when loading a saved patch from disk too.  Wasted hours!!!

Anyway: the easy workaround really is to just keep clicking on the retrieve button until there are no more changes to any of the parameters of the preset being shown on the screen (normally only need to do it twice but three is a lucky number).  Make your changes then save back to the amp. (I've resorted to doing this three times too just for safety sake).  And when loading from disk: get into the habit of doing it three times too!!!

I'll try get their support to have a look at it (although things seem every so quiet over there).

I mention the above because even although we all know the this is not a Marshall Amplication PLC product and is not supported by them: it is indeed punted on these forums quite widely (by myself too).

Regards,

Dale.

This is not a question but a response to those who have asked if there is a way to reduce the output wattage on Code amps to make them quieter. The short answer is no, not out of the box.

However, the speaker(s) that come with Code amps are 4 ohm. In the case of the Code 25, you can swap it out for a Celestion G10N-40 10" 8 ohm speaker (about $70 on Amazon) and reduce the output from 25 watts to 12.5 watts due to the change from 4 ohms to 8 ohms. Instead of running the master volume at < 1 when I'm jamming with my stereo, I can now run it at about 3. The added bonus is better sound - you hear the distortion from the amp itself with less mud and distortion from the speaker. This will not harm the amp in any way as driving an 8 ohm load requires less of an amp than a 4 ohm load.

Full disclosure, this was not my idea. I read about this from another Code 25 owner. Enjoy!

I am wondering if anyone has a preset that will work for using an external effects pedal into my Code 50? I only want to run the external effects (distortion, reverb, delay) and nothing fromthe amp itself. What I am seeing is that even with all effects (amps, modeling, etc.) turned off on the Code my pedal into it sounds like garbage. Very muffled, bassy, and muddy. I have the EQ on the amp set so that the bass is all the way down and mid/tebble are all the way up and it still sounds terrible. I don't want to have to edit and mess with every patch on my old Zoom GFX8. The pedal doesn't sound like this into my old 40 Watt Fender bassman.

Any advice on setting up the Code to sound good with external effects would be greatly appreciated.

Hello,

is there a solution for a better adjusting the Master Volume of the Code 50 . Actually i turn the Master Volume to 1, if i turn it up to 1.4 it's too loud. I don't want to adjust the PreAmp Volume, cause it will change the tone. I want to adjust the overall sound with the Master Volume and keep all the tone settings, no matter if i play at home or with the band. I also read the article "CODE 50 Master Volume Issue " from 26.Oct.2016. Is there a solution in the meantime?

Regards
Wolfgang

I just bought a code 50, downloaded the gateway app and tried to connect it to my galaxy note8.  I find that the app connects my note8 to the amp as an audio player (I can play songs in my note8's music library through the amp) but it will not connect the note8 to the amp as an amp controller.  In other words, I can play music through my amp but not control the amp's settings.  Even though the note8's bluetooth settings shows the amp is paired, the app says it's not connected.  I've followed the instructions found in the code 50 users manual as well as the instruction founs in the app itself several times to no avail.  Can you help please?  Thank you.

I was wondering if anyone has experienced this issue, I bought my CODE 100 brand new back in November and after about a week of having it, the sound began to mute in the middle of my playing for one  to two minutes. Turning the amp off and back on seems to be a temporary fix but the problem still occurs. I have also tried to see if there was a difference in having my CODE connected to the app, and it seems like the amp goes longer with keeping sound while connected to the app but it still mutes ocassionally. I also have the latestest firmware. 

Hi guys,

This isn't really a question but a solution to your problems connecting the Code to Studio One for USB recording. I got it to work using ASIO4All.

Here is a quick 2 minute video I made showing how: https://www.youtube.com/watch?v=LC1FAeFyRn8&feature=youtu.be

Marshall, feel free to point people here if they need this solution. Presonus just points them back to you.

Hello Team,

I just bought the Marshall Code25 and tried to update the Firmware via USB.

I have launched the firmware update from the Chrome Navigator and from Windows firmware application. After update performed, Code25 remains to version 1.11 and firmware indicates my CODE firmware is up to date. 

I have notice during the update than first, the version 1.41 is installed (MCU firmware 1.41) and just after a second update is launched installing the version 1.11 (DSP firmware 1.11)

Is it the regular behavior ?

After the update I still have troubles on bluethooth pairing, even if I read this problem should be solved by the update.

Thanks for your help

Regards

How Can I Program the Tuner on CODE Foot Controller? Thanks!

Hello Marshall Team,

i figured out following:

If code25 is in pairing mode (pressing REV/POWER),  you can see that code25 sends a device name ( something like "CODE V02004FA6E") within BT message to phone and phone asks for pairing, all works ok.

after switching power off and on again on code25, code25 sends again BT message but without device name, I guess the phone can't compare the device and thats why the paired connection can't be re-established from phone.

I checked this with BluetoothView v1.66 from NirSoft with win10.

best regards,

Peter

Is there any design modification being considered that would have a POWER LEVEL control added to any of the CODE amplifiers?

I am finding it difficult to get the level I want to suit different situations, such as studio, personal practice, session practice, etc., because of the sensitivity of the controls when using the amp at lower volumes.

My VOX has a power level control. It is very useful and allows me to use the other controls at the way I want to generate the tones and guitar response without overall volume issues.

Any comments...?

Just got a code 100 shipped to me today, opened it up pluged it in and no sound, plug headset in i get sound thru the headset but nowhere else, seams if i crank it i hear a faint sound from speakers tho, but otherwise any help ?

I'd really like the ability to roll back firmware updates.  The tone of this amp has got worse with each firmware update I've installed.  I wish I would have left it at the default when I got it.

The first firmware update I installed ruined the DSL, and 50's British amps, and now this last update has ruined everything else.  All the presets I created sound completely different now.  What a waste!

I'm really beginning to regret buying a digital amp.
