*** EA iAMP Pro *** GOTTA SEE THIS!!!

#42
I talked with Larry about the new Pro (and the other new heads). In addition to the new look and lighter weight (from the SMPS and Class-D output section), he did mention that the preamps are more quiet than before, with no hiss or hum. So, for folks who had issues with the iAMP 800 (or another model) being too noisy, this may be good news as well.

Yeah, but it only goes down to 4 ohms. The reason I got the iAMP 800 is because of its ability to go down to 2 ohms. That's one of the prerequisites for me because of my cab set up.

I'm also disappointed to learn that the Pro isn't rated to handle a 2-ohm load. Nonetheless, I am eager to read a review of the EA Pro in an upcoming issue of Bass Gear magazine (hint, hint!), especially a comparison of the Pro's claimed 1,200 watts into a 4-ohm load versus the power actually delievered into 4-ohms by the Carvin B1500.

Hey Tom--- can you call Larry back and see whether the iAmp Pro goes down to 2 ohms? I know that's been a feature of the earlier EA amps, but their website does not list that in the specs for this one. They DO say 1250 watts up at the top of the page, but in the Specs section they list 1150 into 4 ohms. I conclude that's 1250 into 2 ohms, but that's just an assumption.

I understand the wanting a single cab @ 4ohms to get maximum juice

and then the need at times for more than one cabinet but good lord almighty, this whole 2ohm fascism thing has got me stymied :hmm:

I'll clarify this with Larry.

2-Ohm facism? Talk about hyperbole!

Right now all of my cabinets are 8-ohm, but going forward, I'd like to have the option of using pairs of 4-ohm cabinets together. To me, it's about not limiting my options, that's all.

Thanks, Tom. :)

Do you know if issue #2 of BGM has started shipping yet?

Yes, it has! Free online digital subs are available now for viewing, the pdf is available now for download, and the print version was printed last week and they should all be in the mail by tomorrow or Wed at the latest.

You haven't heard two wizzys together ;)

But to run two wizzys you need 2 ohms. I think the iAMP500 got it right: optimize for 4 ohms, but make it stable at 2 ohms.

I bet it is the old clip light. I would bet money, and even throw in a beer!, that they are using the same preamp as the iAMP500 since the layout is identical.

EA likes to reuse stuff. The power amp in the iAMP500 is the same as the iAMP800, it just has a less powerful (read cheaper) transformer.

I wouldn't be surprised if the iAMP PRO also uses the same power amp, just with an even more powerful switching power supply.

Same Pre, allnew power amp and power supply

I appreciate the fact they're trying but I don't understand the layout of the doubler. As far as I can tell, like the Micro, there is a switch for channels as well as individual gain knobs?

Also, I find the effects send/returns with mix knob to be kind of superfluous on an amp marketed to jazz players...the whole section seems like it's taking up too much panel space.

Three, and what I really don't understand is, why not 2 combo jacks?

It seems to me they could have done the whole thing in the context of the Micro chassis if they had employed a better layout.

The doubler is essentially a Micro with an added "doubler" Board. Other players other than bassists use the Micro amps (violins, cellos and even jazz guitarists and Warr Players). The effects loop allows them to add the reverb and other effects that bassists might not use.

We investigated using Combo jacks. The IIS (Intelligent Input Switching) needs input jacks with a special switch. Neutrik, our jack supplier no longer makes such a jack or will support it in the future.

Hope this helps

You know, I get the feeling their designs have a lot to do with the players they're consulting for design options... A lot of those guys already have those sorts of magic boxes and are looking for a simplified input layout.

The Doubler had a great deal of design input from Michael Arnopol and others. If you have ever heard Mike's amazing tone and speak to him at any length you will gain an immediate respect for both his theoretical and practical knowledge in getting a great tone
