Team Trace Elliot! Part II

[Downunderwonder]

You may have an amp in there! Cross fingers. So many variants.

Rack ears can be made up easily or possibly get them mail order from the British Audio Services guys. If it's like my amp the holes are there with welded nuts all set to go.

Had a look at the closeup and it seems like the original ears are on it.

 

[searchfunction]

The rack ears are part of the faceplate or should be... like on mine...

42 lbs.. DIM weight for box size... standard gouging by FedEx/UPS/USPS.

Thanks for that. I have an AH250 GP11 thats about 45 lbs. and i was hoping to get a little lighter on the pre-amp. The trace elliot amp head models are confusing. I bought a Trace AH350SM in the mid-nineties just because it was the best sounding amp in the store. I didn't realize there were so many variations. GP7, GP11, GP12, AH, RAH, SM, SMX, Mark IV, Mark V. Makes my head hurt!

Yep! Don't forget the awesome V-type and V4, V6, and V8 amps....

the Preamp weighs about the same as most of the weight is from the Toroidal transformer.


For those that wonder...

AH = Amp Head (in it's own case)
RAH = Rack-mounted Amp Head (no case)
SM = no built in cross-over.
SMX = has a built in (X) cross over.

SMX, -7 & -12 models have a myriad of XLR connections on the back for too many options to list...

AH1000-12 has a special circuit for the BFC cabinet.

You'd have to do your homework to decide which model you "need" let alone "want".

 

[Downunderwonder]

SM = Sound Management
SMX is the designation for having the split HI-LO compression + EQ balance section
SM just has the balance control, crazy handy on the fly EQ adjuster.

An X after the amp power number was for the the ones with a crossover

I think between the two of us and Kelly, we could write a 42 page comparison of the different models and their options

Hi...

I'm looking for an "oldschool" sounding 2x15. How does the 1528 do standalone oldschool sounds? Not to heavy, easy to obtain in Europe, ... So, on that account it seems an easy choice, but I heard some word about it being more of a LF cab to add low end to other cabs.

 

[Downunderwonder]

It's a full range standalone cab for sure. If, by "not too heavy", you mean lighter than an 8x10 then I'd say you're looking at the right cab. I imagine it sounds similar to my 1x15, it's not a 4x10 with a bullet but it can get some spank out if needs be.

Not only can you, but you should!

I was just thinking the same thing...I've torn the innerwebzz apart looking for any scrap of info I can find on mine, and it mostly came down to a .pdf of the generic SM7 owner's manual. A knowledge-base sticky could be kinda valuable at times...

 

[Schlyder]

In everything I have found for specs, manuals, etc... I cannot find one piece of info.
I have an AH250 GP12SMX 250w @ 8 ohm.... but nothing about 4 ohm. It has a second speaker out, so I assume it can run at 4 ohm... but I'm not sure what the output is at 4 ohm. 400w or 500w?

 

[My name is Mudd]

No idea of the output but if yours has two 8 ohm speaker outs, it'll run @ 4 ohms.

And since the question's been asked...my AH130SM is 130 watts @ 4 ohm, and supposedly around 100 watts @ 8 ohms. Can anyone verify the 8 ohm value?

 

[Tracebassplayer]

Not only can you, but you should!

LOL... XL spreadsheet?
I could probably do that as far as specs go.

If I didn't love the black light illumination on my AH1200SM... I'd have the AH1000-12 with a BFC!
I'm not diggin the fiber optic backlighting of like the AH600-12 I have so much but, it's better than no illumination.

Show pic of the back... but...
Unless it says Channel 1 and channel 2... having a set of 1/4" AND xlr jacks for each....
do NOT hook both outputs up.
you have a 1/4" and and XLR output for ONE channel.
The XLR works better than the 1/4" on power transfer to the speakers.

an XLR mic cable does NOT carry enough amperage to power your cabs.

Your AH250SMX should say on the back what it's min load rating is and what your power is.

"250 watts RMS
500 watts peak
Min load 8 OHMS" if it were 4 Ohms it would say so.

My AH1200SM amps are 2 channels out of 600 watts each - 1200 watts RMS / 2400 Watts Peak @ get this ... 2 OHMS

 

[Schlyder]

It does say 500w peak... nothing about minimum load....
... here is the back. The 1/4" line out was installed by a previous owner. This was built in 01/96

 

[VS]

I believe its 250 watts at 4 ohms, not 8 ohms. Otherwise it would be a different model number. -Luke

 

[VS]

I say this because I've never seen an amp that had two outputs have a minimal 8 ohm impedance. It's always 4 or 2 ohms for bass amps. -Luke

 

[VS]

Unless there are two internal power amps. Then I suppose you could have a minimal 8 ohms if it were seperate channels. -Luke

 

[Schlyder]

I'm thinking it's got to be 250w @ 8ohm and 500 @ 4 ohm.

It says 250 w and 500 w peak. Plus the 2 - 8 ohm outs.
It's just not labeled 4 ohm min load. ( that's what I suspect anyways.)

If it was 250 w peak at 8 ohm, it would say 250 w peak and have only one 8 ohm out. That only makes sense. Plus the fact it says peak 500w proves that 250 is not peak.

I would just like to know positively.

 

[VS]

Mine says 250 watts RMS, 500 peak, has two 8 ohm outputs and is a minimal 4 ohm impedance. It's definately not 500 watts total because it is nowhere near 500 watt volume. -Luke

 

[Schlyder]

yes, but you are not going to get a percieved doubling of volume going from 250w to 500w. I have read here on TB that it only equates to about a +6 db increase.
