Cant get my dual rectifier to work

[glpg80]

Read the manual to the cabinet as well. Cabinets that have two 8 ohm inputs most likely have stereo/mono switches. You will want to know which input to use for 16 ohm mono, and which to use for 8ohm stereo.

If there is a 16 ohm mono setting, set it. Plug the speaker cable into the 16ohm input of both that cabinet jack and the 16 ohm output of the amplifier. For the love of god use a speaker cable and not an instrument cable.

This is too obvious to be a troll right? No really right?

Customer Support: "Mesa Boogie amplifier assistant; may I help you?"

Caller: "Yes, well, I'm having trouble with my Mesa rectumfrier."

CS: "What sort of trouble?"

C: "Well, I plugged it in to an outlet and turned it on and had no sound"

CS: "No sound?"

C: "Yeah I couldn't hear anything."

CS: "Hmm. So what is it doing now?"

C: "Nothing."

CS: "Nothing?"

C: "It's dead no sound."

CS: "Do you have a cable from your guitar plugged in?"

C: "How do I tell?"

CS: "See that 1/4 inch jack on your guitar well there is a matching one one the face of your amp labeled input?"

C: "1/4 inch jack?"

CS: "Never mind. Maybe you go wireless?"

C: "I don't have a wireless but I have a cable I can plug from my guitar to the amp."

CS: "Does your Mesa have the amp jewel light on?"

C: "What's an amp jewel light?"

CS: "It's the thing on the faceplate that looks like a jewel. Does it have a little light that tells you when it's on?"

C: "I don't know."

CS: "Well, then look on the back of the amp and find where the power cord goes into it. Can you see that?"

C: "Yes, I think so."

CS: "Great. Follow the cord to the plug, and tell me if it's plugged into the wall."

C: ".......Yes, it is."

CS: "When you were behind amp, did you notice that there were two cables plugged into the back of it, not just one?"

C: "No."

CS: "Well, there are. I need you to look back there again and find the other cable."

C: ".......Okay, here it is."

CS: "Follow it for me, and tell me if it's plugged securely into the back of your cabinet."

C: "I can't reach."

CS: "Uh huh. Well, can you see if it is?"

C: "No."

CS: "Even if you maybe put your knee on something and lean way over?"

C: "Oh, it's not because I don't have the right angle - it's because it's dark."

CS: "Dark?"

C: "Yes - my bedroom light is off, and the only light I have is coming in from the window."

CS: "Well, turn on your bedroom light then."

C: "I can't."

CS: "No? Why not?"

C: "Because there's a power outage."

CS: "A power... A power outage? Ah, Okay, we've got it licked now. Do you still have the box and manuals and packing stuff your amp came in?"

C: "Well, yes, I keep it in the closet."

CS: "Good. Go get them, and unplug your amp and pack it up just like it was when you got it. Then take it back to the store you bought it from."

C: "Really? Is it that bad?"

CS: "Yes, I'm afraid it is."

C: "Well, all right then, I suppose. What do I tell them?"

CS: "Tell them you're too stupid to own a Mesa Boogie amplifier."

And you can also record at low volume with a cab simulator DI box (hughs and kettner red box, Beringer Ultra G for $39 on Sweetwater, etc etc) between your amp and cab at low volumes, I do this all the time at TV volume and while not the best sound ever it is certainly passable and better than what you are trying to do. Your amp will still play thru the speaker but it will send the signal now cab simulated to your mixer and you don't need to mic up the cab. We now understand you're new to all of this but a little self education via the owners manual would make things very clear and then if you ask questions they have some basis in reality. Your post came across as desperate and clueless and not willing to try to help yourself and look up anything (there is a ton of info just google tube guitar amps etc). All said we hope your amp is OK. Let us know how it goes with the cab. And please, do yourself, your amp, and us all a favor and read the manual on Mesa's web site.

If somebody really wants to help me inbox



Powering on your Rectifier without a cabinet is the equivalent to walking around the gun range with your booger hook on the bang switch... .

I haven't laughed that hard in a long time. Thank you.

You are welcome. I will be here all week.

The cab I have is 8 ohms, and Im still fucking confused cuz it has 2 8 ohm outputs. So its not like Im a fucking retard, I just have never owned a tube amp before. So this is my first day. Some of you guys have been doin this shit for years and had teachers. Here is a picture of the back

For the love of pete, read the fucking manual if you don't understand how it works. If you don't have a manual, download it from mesa's website. They are so easy to understand that even an actual retard can understand it; so you should be fine

I have the manual, I did read it but im tellin ya bro I dont recall ever seeing in big exclamation points DO NOT TURN AMPLIFIER ON WITHOUT A LOAD ATTACHED OR YOU WILL FRY IT !!! Trust me I woulda remembered that shit

Read the manual to the cabinet as well. Cabinets that have two 8 ohm inputs most likely have stereo/mono switches. You will want to know which input to use for 16 ohm mono, and which to use for 8ohm stereo.

Whats a speaker cable? Im serious dude

Is it so difficult to understand I thought the signal coming off the power amp was the same signal you can record into your computer? Nobody ever told me any different. The way I understood the pros to do it was mic the cab. But I dont understand how they do that, yet crank the amp to get that killer tone without saturating the mic at high volume. So logically thinking, I figured thats the way they used a direct line input via my usb interface. Its a human mistake. I dont pretend to understand ohms, and tubes and pre amps

Go back and read the thread.......its explained at least 4 times. Not being sarcastic. Good luck man.

What's a speaker cable?
Basically an unshielded cable
Instrument cables are shielded
Go to the music store and ask for a speaker cable

I could almost hear your head hitting the desk...

When you blow it up I'll give you $300 for it

 

[thegreattailz]

All these years ive been using an instrument cable between my head and my cab? So whats the difference? Are we talking like the difference between guitar center cables and monster?

I would like to see a diagram of how the the pre and power amp stages work along with the fx loop. I tried looking on google images and didnt find what I was looking for, so ask the guitar message board

 

[Anonymous]

They're not different brands/quality, just built differently

All these years you've been quite lucky to not blow anything

 

[glpg80]

I know where you're going with that and regardless of how the effects loop works you will always need a load on the amplifier. As long as there is plate voltage on the power tubes a load needs to be present on the output transformer secondary. Period.

The only thing you need to know is that an effects loop has a send and a return and can be parallel or serial. It is used for instrument level effects. You do not need to know anything more about the inner workings in regard to poweramp and preamp.
