How is impedance of a cabinet identified/determined?
On a model Jmt45 O/S which speaker Jack should be used?
Thank you for your time and attention
This is probably something you've answered before, but I want to run an extension cabinet with my DSL40C, found the PRS Stealth 70 to be the appropriate size to enable stacking and, since it's a 16 ohm cabinet, I assume I can plug the internal speaker into one of the 8 ohm jacks and the PRS Stealth cabinet into the other 8 ohm jack.
Oh, by the way, I should have checked before I dropped the cash on the cabinet, I know...
When I just play the guitar I get sound from both sides of my headphones. When I use the bluetooth or use the mp3 in jack and play a backing track it cuts out the right side headphone.
When I play with no hedphones it sounds fine thru the speaker.
Is this normal or do I need to change the settings on the output from my phone or something?
Actually I'm totaly not interested in bluetooth connection, but of course I understand that it might be an essential prolem for some people...
But there are some other problems I'd like you to find good solution for.
1. Master volume. From 0 to 10% there is almost no sound, over 10% it becomes very loud.
2. Decreasing sound level with Volume pot results in decreasing USB signal level - not acceptable for players using USB output for recording in DAW software. It would be nice if for clean preamp gain at 2 and volume at 3 give recording level about -6 dB, now it is about -36 dB...
Best regards, Jacek.
P.S. What is a frequency range of CODE 25 speaker?
Someone unplugged my cabinet. Which speaker output should I use with the built-in speakers?
Hi, 3 question:
1) I'm Italian and I just purchased on ebay a brend new DSL40Cr from a UK shop. I was wondering if the ampli still works at 220V - 50 Hz as per manual, regardeless the fact it comes from UK, and if will arrive with power calbe schuko plug or UK plug. In this case may I use an adaptor male shuko/female UK ?
2) I would like to know if I can use an external speaker as additional together with the internal Speaker, for example the internal 16 Ohm speaker + an external 8 Ohm speacker connected obviously at right socket.
3) in case of use of one external speaker (e.g. 8 Ohm ) which one I should connect of the two socket where is labeled down "1 x 8 OHM - 2 x 16 OHM" ? is it indifferent, the one to the left or the right ?
update for the question n.2: maybe I figure out how it has to be done: unplug the internal speacker from 16 OHM socket and plug it into the 8 OHM speacker. plug a 16 OHM external cabinet into the other 8 OHM Speacker socket. otherwise only configuration showed on manual are allowed. Is that correct?
Firstly, I would like to say what a great site.
Secondly, forgive me if this has been asked elsewhere.
Ok, the question is:
I have a Marshall origi n 50 head(beautiful bit of kit!!!!)
And a marshall 1936 cab.
The issue i have is which speaker connections to use.
The manual forvthe amp says socket 3 at 8 ohms, yet the back of yet amp shows socket 2 as 8 ohms!!!
Also even though amp is not stereo can i use 2 speakef cables ftom the 16ohm sockets????
A bit crazy i know but dont wznt to blow me new amp for the sake of asking the great znd wise
Many thanks in anticipation
Hello everyone. I just purchased a used DSL40 today and I want to use an extended cabinet (16ohms) as well. Do I move the internal speaker to an 8ohm spot and the external cabinet to the other 8ohm spot? Thanks - Chris
I'm using a Origin 50 combo. I find when I crank the master volume and play at higher volumes, I get what sounds like glassy tube rattle. There is also just generally more noise than I would expect. I tried it with a different cabinet. It seems to be worst when using the internal speaker or when the amp is sitting on top of the external cabinet... my assumption is that the physical vibrations due to high volume are causing the tubes to rattle. The rattling is getting passed through the speaker, meaning that it is not just simply a physical rattle, but it is a transferred into the signal.
It sounds similar to some of the problems on the internet with the Class 5 that had rattling. Someone suggested that tube rings would fix it. Any suggestions?
Hello, Marshall forum family. I just purchased the CODE 100H (head only). I have a Marshall cabinet with 4x12 MG series, and I hate the sound of this combination! Does anyone have advice for a replacement speaker?
Thank You All
Like the title says - I'm wondering if its possible / safe to run the Origin 50 head with the DI connected to a recording device and not connected to a traditional speaker load.
Hi there everyone, it's my first post here. I just acquired (2nd hand) Marshall VBA400 Bass head amplifier. It sounds really great but I just want to ask anyone from here has got the same experienced with an audible "humming sound" when the Standby Switch is turned ON... is it normal for this model? one more question, when i got the VBA400 it comes with Marshall MG412A speaker cabinet (4x12")... are they both match to use technically?
So i can get a good deal on the Marshall Stanmore speaker (130€) Has anyone here had experience with this speaker in particular? Can you recommend it?
I have recently been given the above amp and before I connect it to a speaker and switch it on I am concerned to know the correct protocol for connecting a speaker cabinet(s). The speaker output sockets have no information directly next to them but a label elsewhere on the rear of the amp states "WARNING. Not to be used with speaker cabinets of less than 4 ohms"
My queries are:-
1. Is it safe (i.e. without risk of damage to the amp) to use just one speaker output as long as it is connected to a speaker cabinet of 4 ohms minimum impedance and appropriate wattage?
2. When using both speaker outputs can they both be connected to cabinets each of 4 ohms minimum impedance or are the outputs paralleled in which case would I need to work with two cabinets each of 8 ohms to arrive at a 4 ohms minimum impedance in total?
Apologies if the answer to this seems obvious but I have a little knowledge of these matters and while a little knowledge can be 'a dangerous thing' it can also lead you to be concerned (possibly unnecessarily) about getting things right!
Thanks in anticipation
I just purchased and plugged in my hundred-watt code amp head prepared to plug it into my full stack two 2 cabinets and it only has one speaker output Jack on the back I am confused befuddled perplexed and never heard of such a thing as specially for Marshall what do I do to run it to both cabinets can I use a splitter box I'm feeling like a snowflake somebody help? Lol
My MA 50C has an internal speaker that is at 16 ohms and the amp is wired for 8 ohms max. I have a 2x12 cab that is at 8 ohms that I can plug in - BUT (and this is the question): Can I leave the Internal speaker plugged into the amp (again, at 16 ohms) and STILL plug in my 2x12 cab (8 ohms) without doing damage or do I have to unplug the internal speaker before I plug the 2x12 in? By my math (and this is always very questionable), it should be able to handle it because it will not make the amp go lower than the 8 minimum to get the full 50 watts. I need another set of eyes/brain to confirm/refute. Thank you in advance!!!
Please can you (Marshall) tell me if the speaker in the CODE50 is a FRFR ("Full Range Flat Response") speaker???
Or is it an actual guitar cab. speaker (that may have been specifically voiced for the CODE50)???
Of course anybody else's comments would be appreciated.
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.
If I want to plug my 100h into my PC via USB, does it still need a speaker load or can I use it without a cab connected?
I bought a CODE50 2 months ago, and while I really like the sound, it generates cracking/tearing/popping sounds when I apply (even small amounts of) overdrive when I touch a string with my pick/plectrum. I use the JCM800 emulation with low gain and low presence. I have also tried other AMPs such as the JVM. Plexi or Bluesbreaker, but that does not make any difference. It occurs with a BOSS Overdrive OS2 pedal and also with the ODR that is build in, also at low levels.
It happens both with my Fender Stratocaster and my Epiphone Les Paul. I also tried several diffenent plextrums, for example the Dunlop Jazz III, Dunlop Tortex, Fender medium, light and heavy and a few others, but that does not make any difference.
I opened the back of the combo so see if anything touches the speaker that could explain this sound but that was not the case. Normally I like a bit of pick attack sound, but this noise can be so loud that it overshadows the sound of the string, almost like a series of explosions. When I switch the overdrive off, this noise effect is gone.
What could be the reason for this ?
