Hi,

I own a DSL20HR amp and I'd like to connect two 1x12 speaker cabinets to the amp simultaneously. Both cabinets are Marshall 1912 cabinets (1x12", 8ohm speaker). There are three speaker cabinet output jack sockets in DSL20HR:

one 1 x 16 OHM socket to connect a single 16ohm speaker cabinet, and

two 1x16 OHM sockets to connect two 16ohm speaker cabinets simultaneously or to connect a single 8 Ohm speaker cabinet to either one of these sockets.

How do I connect two 8ohm cabinets to this amp? I'd like to connect these cabs in series to have 16ohms in result, but the cabs don't have sockets for connecting them in series. There is only one input in 1912 cab. And if I find a device to connect this two amps in series, do I then connect the first cab's input cable to the DSL20HRs single 1x16 OHM input (the first input option)? Is this safe? The manual doesn't say anything about connecting cabinets in series.

Thank you! The new amp is great btw!

Hey all, 

Who has been working on the schematic for the new DSL 1w (2018)?

I've got mine open and have started thinking about some tone mods but would love any help with the schematic, part schematic or even a mod list.

I'd be totally happy to hack mine up first if anyone has a mod idea too.

I can read a schematic but I'd completly f%^$ it up if I tried to wrtie it out just via the PCB so if you'd like to help let me know and I'll send the high res pics ( assuming you dont have a 1w yourself).

Also I'd be all ears for some tube advice. I've put a 5751 inplace of one of the 12AX7 and its a bit better to my ears. I'm going to say V2 is the dirt channels V yeah?

So far I love it and i'll be interested to see what Blackstar do next with their future 1w.

Dear Marshall,

I have the Marshall AS50D.

Can i use the line out jack to connect a wired headphone to it so i can use that as in-ear monitoring? Or will it blow up my headphones, my ears and my head?

Could i use the D.I. Out to connect a device like the Fischer Amps mini body pack, so i can plug my headphone into the Fischer Amps mini body pack and thus have a volume knob close at hand? Link: http://fischer-amps.de/en/in-ear-monitoring/mini-body-pack-xlr-oder-klinken-eingang.html

Or does Marshall have it's own solution for this?

I use the Marshall AS50D to sing and accompany myself with the guitar. When i have a gig in a restaurant they want me to play silently (lol) but then i have trouble hearing myself because of the ambient noise and i start singing out of pitch which is like a weapon of mass destruction.

But i can't say: stop talking, stop eating and stop using your cutlery, because, well you know, it's a restaurant and all that. So therefore i need an in ear solution. Preferably wired because wireless is too expensive and not necessary too, since i'm not allowed to stagedive in a restaurant (anymore).

Best regards,
Johan

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.

.

I'm finding it difficult to achieve a good blues tone from my code 25, if anybody has surgestions for amp settings it would be appreciated. I'm using the amp with  Les Paul.

cheers. 

This past week (three days ago to be exact) I purchased and took delivery of my second Code™100H amplifier head. I was told

by a friend of mine that this head is being discontinued and no longer in production ― and my online dealer was discounting it

for $150.00 off the regular sale price.

In my opinion, the Code™100H ranks right up there with the very best sounding amplifier heads that Marshall Amplification PLC.

has ever produced; the 1959 Super Lead MKII ‘Plexi’, the Silver Jubilee, and the JVM100H.

Why Marshall, is this most excellent amplifier head ― with its extremely vast array of super-high-quality sounds ― being discontinued?

My guess, is an immense lack of promotion, patience, and education on the infinite possibilities that this amplifier can produce ― if only the user would

spend some quality time listening, tweaking, and editing . . . It took me less than ten minutes to edit my four favourite preset sounds.

Perhaps this fine lady said it best: ‘You get to have whatever you want . . . with a side of whatever you want . . . ’ ― Nita Strauss. 🍴🍰🍴🍰

Good day,

I try connect Marshall Acton to my PC with Bluetooth 2.0, but require PIN code. 0000 or 1111 not work.
What is the pin on this speaker?

Especially on low strings, low notes.

Worse on neck pickups.

JTM45 especially bad.

Or is it just that my guitars have hotter pickups? Then again, some of my neck pickups aren't that hot and even switched to single-coil, it gets muddy and boomy.

The settings don't really help. Tried changes on all settings... EQ, cabs, preamps, amps, presence, resonance, you name it.

Or is it because I play at room volumes? Still need to try a headphone to see if it's speaker or emulator...

Hi,

to whom it may concern.

I would like to ask a help with the preamp layout in JVM 410 (2007). I have found this online but it says "Assumed". As you know the tubes on board starts with with V1 a power tube to V4 so it is hard for me to assume.

Could you please confirm if this diagram is correct (bottom right of the picture)?

thanks in advance,
marcel

Hi.

I have a set of Minor II Bluetooth headphones and they’ve worked great up until I switched from an Android phone to an iPhone. I like to have them connected to my phone and also my laptop at the same time whilst working. The problem is since I’ve been using the iPhone, I keep hearing the short noise as if the headphones have just connected to a device over and over again. Every minute or so, the sound dips and I hear that noise. It’s extremely annoying and I end up having to disconnect from the phone to stop it. Does anyone know how this could be fixed?

Thanks

My Marshall Code 50 has been working very well until recently while im playing the speaker will just cut off out of nowhere. I am trying to see if anyone would know how to help with this problem. Thanks.

I wanted to update my new Marshall Code25. I ran the website in Chrome and plugged the amp. It found updates, so I clicked the 'Update' button. The installation has begun and now it seem to be frozen... I have information: "Installing firmware - please wait.. Restarting in bootloader mode... ", but I'm actually waiting for like 4 hours.

I'm afraid that the software may corrupt if I turn off the amp or unplug the cable.

Anyone help?

Tried out the effects loop over the weekend and whether I run one pedal through it, or loads, tried different cables, power supply or battery, the loop adds a high pitched whine to the sound, which makes it pretty unusable.

I'm going to re-try a load of things, again different pedals, batteries and cables, but do Marshall have any suggestions?

Also is there a way to change the level/mix of the effects loop, or is it fixed?

Quite a few people on various forums are concerned about the emulated out of our DSL20H and DSLCR amps. It seems that there is a set level for the emulated line out and headphones which can only be adjusted with either the guitar volume knob of gain channel knob. The channel volume does nothing to the line out/headphones only to the speaker output.

Is this normal behaviour? Where the gain knobs are the only controls on the amp that increases the loudness of headphone/line out. 

Hello, I was recently shipped a DSL40C and there was no owners manual or warranty card. The amp is brand new, in the original packaging. I am bumbed out, because I like to save these items. I know I can probably download one, but I want the original that is supposed to come with the amp. How do I obtain these items? Tommy Scott, 6625 Van Buren Road, Warners, NY 13164.

PS: Great Amp!

I have a Woburn II speaker and I've paired it to my HP Envy Laptop but I keep seeing a LOW BATTERY message. I see that the device is paired but cannot play via bluetooth because of LOW BATTERY. The speaker doesn't have a battery.

hello Marshall Team

sorry but i have a other question!

i want to use the Turner with the Marshall Code Footswitch.

i have the Code 50.

witch buttons on the Pedl i have to push to turn on the Tuner?

maybe i'am blind, but i cant find it, also dont find in the manual...

thank you

So I just got my CODE50 two days ago and yesterday was the first day I had to play around on it, and that being at a live rehearsal of all places.  I didn't get to do much tweaking, but I noticed a problem with the EQ. If you have all buttons deactivated then the Bass Mid and Treble knobs do absolutely nothing, NOTHING...  I tried using the Natural preamp thinking that maybe the EQ knobs are strictly digital and an amp or preamp needed to be activated to enable the EQ to function.  When the Natural preamp was selected, however, the overall volume (master knob all the way up and the volume knob at 12 o'clock) was so low hardly anything could be heard.  Am I missing a menu option to set the volume or something?

Also, I've saw a lot of people having trouble getting the Marshall Gateway app to connect to their CODE amps, myself being one of these people unfortunately, but I haven't saw anyone come up with a definitive solution other than 1. Updating the Firmware 2. Turn the amp and phone off then restart both of them and try again. 3. Delete the amps Bluetooth profile from your phone and repeat step 2. 4. Call Marshall support.  I can get my Samsung Note 5 itself to connect to the amp (getting a weird message on my phone that says verify such and such number is the correct PIN for the Marshall amp but not having any further prompts on my phone or on the amp after tapping OK, but still connecting regardsless), but when I bring up the Marshall Gateway app and go into the menu to connect to the amp I can hit the scan button all day and it will NEVER find my CODE50.  What the huh?!!!  With all the other people I've saw on this forum having the same problem with the Bluetooth connectivity, you would think there would be a end-all-fix-all solution to such a massive problem. Has anyone heard anything or should I send this amp back for a refund while I still can?

Hello,

So I got these Marshall Monitor headphones from apple over in boston last august and they were working just fine until two months ago when one of the sides of the headphones when out and would not produce sound, so I put the headphone jack in the other ear and it was fine, but then it happened again with the other ear.

I was just wondering if Marshall can fix this problem or if anyone else has had the same problem with these head phones.
