I know that turning a "TUBE" amp on without a speaker load on the output will damage the amp.
(the no-load condition will cause the output voltage to increase until the output tubes burn out, which can then lead to other component damage)
Is this also true for a CODE 100 amp? Is there a risk of damage to the output section, with turning the unit on without a speaker cab load connected?
Would it be safe to operate the amp with just headphones connected instead of a speaker cab?
Would it be safe to operate the amp without either a speaker cab or headphones connected?
I ask because my computer (which is a desktop) is in a different location in my house than my amp.
Doing firmware updates or testing out patches requires either moving my computer or my amp, both of which are very inconvenient.
It would be much easier if all I had to move was the head.
I’m looking into getting a new IPad and I was curious if I can use GarageBand as my software and record direct from the USB port on my Marshall code 25 to record? Or should I spend the money for a new Mac book or Mac laptop will either of those work?
does anybody know how to pair the apple watch series 4 , it only says the code to pair but i cant pair it . thx i hope it can be pair .
I have just updated my CODE 25's firmware to 1.44. Just after this, it started to make a sound like tapping or heartbeat. I am not sure but it's similar. First, I thought that it's about tap tempo so i turned the amp off and turn on again but it doesn't work. Amp still makes the sound regularly. Before the 1.44 update there was no sound and AMP was working perfect. So if there is a sloution, I really need help.
Thanks.
Hi bought the code100h and love it so far, I already had the mg412 4x12 cab which is 80hms 120w is this ok to run with the head and not cause any problems with my amp? Or do I need the actual code cab?
Hey you guys ! Still loving my Code, for light rehearsals and mostly direct into my recorder! Any chance of Gateway for Windows PCs? I dig using my Code direct to my computer Studio, and it would be cool to have the Gateway on the big screen as well! Just wondering.
Thanks
Can I / How do I download a preset from MyMarshall to my phone and then from my phone to the amp (Code50)?
Thanks all
I get no guitar through the headphones. What must I do to get the audio from my guitar to the headphones? I would like to use this as a line signal to another amp.
I do get audio out from my phone to the headphones when Bluetooth is connected. When Bluetooth is connected, whatever is playing on the phone will be heard through the headphones. So, I know the headphones AND the headphone jack both work.
Cable plugged in to both computer and Code 50. Display shows 'Ready for Update' - but neither the browser or Desktop Utility will connect.
Rebooted everything and tried from laptop. Same results. What's wrong?
Why can we not update via bluetooth connection rather than USB cable?
Hi There,
I have been using my Marshall code 25 since last yr and noticed that when the amp is plugged and NOT turned on. There is an electric current at the end of the cable. It only dissapears when I turn on the AMP. The electric current runs until the guitar when its plugged. I have tried the cable on other amps and it was fine.
Has anyone experiences this? or is this normal?
Appreciate the response.
Hello
I want to exchange valves in my Origin 20h, ordered some from Tube Amp Doctor. After I exchange them do I have to rebias it? Is there a manual for rebiasing? I wasn't able to find anything which would give me even slight bit of a hint about it .
thanks

Does anyone have a good heavy Robin Trower (like Bridge of sighs stuff early early stuff) and please don't say HENDRIX......thanks D.Wells
I have a code100H with a 2x12 ext. cabinet,can I plug my ovation in I would like a clean sound but maybe a little chorus?
do I need to have a speaker connected to thecode 100 if I am using headphones?
Does anyone have a Steve Lukather sound dialed in?
I think I might have tossed out my USB cable by accident! I cannot find any place to order a replacement one, not even on Marshall's web site.
Hey Marshall, you ahve my email, why not tell me how much and where to pay so I can get a replacement and update my Amp!!!!

after correctly updating the CODE AMP and the Gateway, the connection is still wrong, I had hope with the last update but it has not helped me at all.
he version of android that I use is ANDROID 9, with the phone Galaxy J6 + ..... I do not understand where the problem may be.
I would appreciate Marshall's help in correcting this problem, they have already contacted me for a long time but the guidelines were erroneous from the beginning.
Thanks for all.
Can I save downloaded user presets to my footswitch and how???
Using the Code 50
Dear Marshall Team,
It took some time, almost a year, but finally we got the long awaited update of the firmware to fix the painful Bluetooth issue on CODEs. I installed it a few days ago (which was a bit of an issue as reported in another of my posts but finally succeeded) and now CODE does what it is supposed to do. BT comes on and connects as it should every time I turn on the amp and start Gateway on my Ipad/Iphone.
I'm very happy that you could fix the problem and I encourage all brothers and sisters in pain to upgrade the firmware asap if they haven't done already.
In the light of this fix I think we, the community, may also forgive you that for months you told us that it is not a firmware issue ;-)
So far I also think that the BT connection is more stable than it used to be.
Now I can enjoy again my little CODE 25.
Thanks, Alex F.
Running V1.43 firmware.
I have followed all instructions and can not get the iPad 6 to connect in Gateway app.
It, however "pairs" just fine Bluetooth wise on the iPad 6!
AND Gateway works well on my iPhone 5, switches presets and everything.
So I know I am doing this right and the Marshall code 100 Head is responding via Bluetooth (with my iPhone 5) but NOT with the iPad 6.
Edited: Its the damnedest thing. I removed and reinstalled the app on my iPad 6 at least 8 times with the same results.
Then I reinstalled and paired the "9th" time, and it worked!!!!
I can turn the 100 Code head amp off, and back on and it still connects.
I'm glad it works now, but I dunno what I did differently.
