Hi,

Question about connecting a Model 1982B 4x12 lead cabinet to my Model 4211 JCM800 100 watt lead combo.

I just want to be sure on the ohms before connecting the 1982B. Both have been in storage for over 30 years. I have already tested the 4211 combo and it is working fine, It has 2 x G12T-75's connected to one of the two speaker jacks in parallel, with the ohm dial set to 8 omhs. The Model 1982B lead 4x12 cabinet has 320W RMS and 8 omhs marked on the plate. So the questions are...

1. With the 2x16 ohm combo speakers in parallel the amp should be set to 8 ohms on the dial, correct?

2. If I disconnect the 2 combo speakers and only plug in the 4x12 cabinet, the amp stays at 8 ohms?

3. If I connect bothe cabinets, combo at 8 ohms and 4x12 at 8 ohms, should the amp be set to 4 ohms?

Sorry if this sounds like a dumb question, but both these things have survived over 30 years in storage, and the last thing I want to do is screw them up by being an idiot and connecting them wrong and frying them.

Thanks for any help in advance...

My JVM 410C doesnt have any volume coming from the channels.

One switch works green yelow, not red.  Works fine with switch two.  Switch three works green and yellow, not red.

switch four doesn't work at all. 

No sound out of these channels without footswitch.  Same results.  Now, making a poping noise when turned off.  I just got htis amp in June.  Played a few weeks and then boom, nothing.

I tried using the FX Loop in back.  That's when this whole thing started.  As I correctly plugged in as instructions say, it immediately didn't make sound in these channels.  Unplugged, guitar going straight in, same stuff.  No volume through these channels.

The tubes are red, all glowing.

I need help.  Thanks.

Hi there!

Do you know a way to use bluetooth connection as audio transmitter on Marshall Code 25?

I have to practice at midnight, so i need to be silent for my neighbours.

Otherwise only solution is to buy a bt transmitter? Any idea?

Thank you all who read this.

Hello

In the manual is told not to use the Code 100 head without a speaker? Why?

I think it's not a valve amp.

I need to find Marshall app on the play store store. It may have been broken who could help me find it. Thanks in advance!!!

The presets list is different on my code 100 head compare with the Marshall gateway  (the first 14 presets)  so is the 100 head different compare to Marshall gateway or the other code amps?  and i tryed to reset the amp  but the presents still different compare  to the gateway.

Hi, I have a question about the Studio Series SV20H and SC20H DI OUT

The user manual say the DI OUT have emulation, but in both of your official product video on youtube (for SC20H and SV20H), Steve say the DI OUT is NOT emulated so it's perfect to use with our own Impulse response...

So who is right, the user manual or Marshall official product video?

https://www.youtube.com/watch?v=GvuQPnqMktc   at 2min43 he talk about the DI OUT and he say same for the video for the SC20H

Thanks in advance!

So ive been using my code50 for about a month now. Only really used it at my house and im getting on really well with it, i love it. Dead easy to use and like using a mixture of gateway and pedal.

I took it to band practice the other day, a chance for it to really show me what it can do. Turned it up to about half way on the master volume and i had this horrible screeching feedback come through every time i even touched my guitar strings. Almost as if my guitar was right up against the amp but it wasnt. 

Was fine on a clean setting, only when i had it on a distorted setting

Anyone else having this issue? 

I read some of the recent questions on the code lockup problems and your answer says that a new firmware update is released for this problem but when i downloaded the update and i checked the file version in windows it was the same as a previous file version i downloaded over a month ago? 

File version 14.0.23107.0

Hi all, I was hoping I could get an owners manual downloaded for my JCM 2553 that I recently acquired. I can't seem to find the old manuals on the marshall site since they updated it. Thanks!

I need to buy headphones for work, and to practice guitar at home.

For work I need bluetooth headphones, but for guitar practice, I need wired.

I've already had problems with my Sennheiser wireless headphones, so I want to make sure thse are compatable with the code 50 amp.

Can someone confirm that the major II headset will work with the code 50 amp using the 3.5m mini jack cable that comes with the headset?

Thanks

I'm a new owner of JVM410hjs, I just found out that the serial fx loop got problem

I have plugged in an effect chain into the fx loop, I have enabled the fx loop on the front panel,

what my question is that if I haven't plugged in the power supply for the effect chain, i.e. the effect chain in the fx loop is dead as there are buffered bypass pedals inside. The fx loop is serial loop thus at this situation, the amp must be dead silent. But the reality is I still hear a low volume of my playing through the cabinet, this bleed through is normally happened in parallel loop, but why my hjs serial loop also do that? Is that normal as the circuit designed is like this or my jvm is defected?

what footswitch is used with theAS50D? Will the PEDL91003 ? It said in manual PEDL-10029 can not find one to buy?

thanks

Ive had this amp five days now and I’m totally frustrated!

Here are my issues:

• Bluetooth Connectivity

The amp loses connectivity with the MyMarshall app constantly!  I’ve followed the instructions.  I’m sitting less then a foot from the amp, yet it loses connectivity from both my iPhone and two different iPads.  It literally takes me 15-20 minutes to get the thing connected, reconnected, and then, BOOM! Again, the sound changes settings on the amp mysteriously, this after taking 15-20 minutes to get the sound and effects exactly the way I want it.  I can’t save the setting, because it disconnects the app from the amp, even though it says on the amp and my iPad settings, that I’m still connected.  Utterly frustrating! It also limits what time I have to practice because I’m spending most of that time trying to get it reconnected and sounding right again.

Also, after following the directions explicitly, I still have to  reconnect the Bluetooth from scratch every time.  The app sucks.

• Apple OSX /iOS compatibility

Guys, Your the best amp manufacturer in the music world.  The music world is OSX/iOS based. Get your brilliant minds together and allow for the amp to be Updated via Apple products!

• The amp and application

This is a great sounding amp, I’m enamored with the sound as I am with most Marshall Amplification products and the price well within reason, but not just the app is HORRIBLE, but also the effects are also less then desirable.  I just can’t seem to get chorus, phase, flanger or echo sounds to my tastes and desires.  Same with the auto wah.  I just can’t believe you can’t duplicate the same great sounding effects as you have in many of your solid state amps.  

I’m hoping you can help, if not, this amp is going back in the box and being returned.

When I download presets from the My Marshall website, how can I then transfer/import them to either the Gateway on my iPad, or to the Code 25 amp itself?

I can control the amp from the iPad, but it will only let me use the 99 presets already loaded.

I have a Marshall DSL 100-watt head purchased in 2016 (so not the newest version), whose channel switching and onboard reverb I would like to operate with a Fractal Audio FX8's relay function. The manual for the FX8 clearly states that its relay function is only to be used on amps with "short-to-sleeve" switching. My questions are, is the Marshall DSL100 head built with short-to-sleeve channel switching? And also, do the channel switching and reverb on/off functions on the amp behave in a latching manner (i.e. the effect remains on as long as the switch is engaged) or an auto-off manner (i.e. the effect is triggered by a momentary connection)?

Thank you!

Hello.

I have a marshall JVM 410 combo, and connected a extension cab JVMC 212,16 omh,I get an amazingly god sound.

Can I connect two JVMC 212 cabinet without damage the amp in any way? If not,is it a another way to connect one more cab?

Maybe I can use two 8 ohm cab?

I maybe ask silly no, but hope it is possible?   :-)

Thanks for reply.

Greetings from Norway.

I just wanted to ask why the amp head is in standby mode when the switch is in the off position, rather than the on?  Rather confusing, and seems others have run into this as well but with no real answer. Or is something wired wrong on some heads?  Full playing power comes up with  the standby switch set to on, which seems backwards, so I'm asking what the reason is for this.  Thanks!

Hello,

I use  a Marshall DSL 40 C and i would like to have an extension with one  Marshall 1960 AV. 

On the Marshall 1960 AV ,  connections are  : -1 x 4 ohm imput or 8 ohms right

                                                                                                       -  1 x 16 ohms imput or 8 ohms left

                                                                                                        - a selector for Mono or Stereo

I read that he DSL40C can drive either 1x16 ohms ,1x8 ohm or 2x 16ohm cabinets.  

My  questions are  : 

Can  I use the internal speaker and the external cabinet together  ? . I know that to use only the DSL 40 C , the connection is on the 1 x 16 ohms socket.

I have only  one cabinet , which selector position is correct ? Mono or stereo.

Which connections are correct  ?

Thanks for your help .

Regards

Fred
