That's an AH300SMX head (280W power amp, rounded up to 300 for the numbers name game!). Nice amp and in fine condition, I'll give you a tenner for it

You can probably sell for up to about £300 I think, I sold a later model for £275 last year.

 

it's a pretty good idea, when buying and selling music gear, that you will lose money. sometimes you might come across a great deal that offsets it a bit but you will almost always end up selling for less than you paid, especially when buying things new.

 

Hi!

I have the same amp and have kind of a problem with it and this was the only reasonable thread that I found for posting (though it's a bit old).

But, to the problem. I have the same amp (AH300SMX) from -96 and there stands that the amp is 280w RMS and 580w peak and I was sold a TE cab (1048) that says it's power handling is only 200w and it's starting to sound kinda "mushy" when playing loud. And people are always talking about "TE watts" and really is loud when comparing to other amps but does the same stand for the cabs?

So I assume that I could get another cab with it so they could handle the power when playing louder, or does somebody have any better ideas?

Thanks!

 

I can't find any manual or details on this amp.

What is the impedence of your cab?

What is the minimum impedence of the amplifier?

 

They both are 8ohm, don't know if the amp can handle low impedance cabs but it says 8ohm on the back and on the cab also so it's not about that.

 

You'd have to try and find out what the minimum impedence is. If it is 8 ohms, then you couldn't add another cab in parallel.

 

But does it matter if there's 2 separate connectors on the amp both stating 8ohm (like it shows on the back on the picture)? Couldn't I just plug 2 cabs straight to the amp, doesn't it just divide the output power to the two so 200w would be enough on one of the cabs?

"The two speaker output jack sockets are intended for connection to either a single 8ohm cabinet plugged into one socket, who 8 ohm cabinets with one plugged into each socket or a single 4ohm cabinet plugged into one socket only."

So wouldn't another 8ohm cab connected to the other socket solve my issue with this, if it is about that?

 

If that's the case it sounds like a 4 ohm load minimum. Which would mean you could run two 8 ohm cabs in parallel.

And yes, this would send half the power to each cab. However, you would also be getting more output if the amplifier was at 4 ohms as opposed to 8ohms (generally with SS amps anyways). So if it was 280 watts at 8 ohm, it would be about 500 watts at 4 ohms, meaning each cab would get a maximum of 250 watts (of course this is if you are running the amp at its limits)

 

Okay and I was thinking about that too, but it's loud enough for me with our band at half the volume so maybe I'll just start looking for a 8ohm cab and hook them both straight to the amp and if I feel the need it louder I might put them in parallel. Now I just have to think if I'll get another 4x10 or a 1x15.

Thanks!

 

The speaker jacks are wired in parallel already, so hooking up two 8ohm cabs would create a 4ohm load to the amp section.

 

Hmm, that's a very good point. Didn't even think about that but should have seen that from the schematics

Thanks
