adapter

well i cant remember what it takes and alessis site wasn't helpful... so.. look at the old one and compare... the issues are ac v dc output ... whether the center pin is pos or neg on dc units... and the current capabilities... what you want is for the adapter capability to be slightly more than the unit draws... in other words a ubit that draws say 800ma should have an adapter rated 1000ma/1amp... make sense??? dont use if it's under voltage... over voltage??? not a great idea but likely ok if not too extreme... most of these kindsa units have a zener diode for regulation the first thing inside...

Thank You For the answer.

It did function, but now I have an other problem.
It seems like thevAlesis Microverb III does not function together with my Edirola UA25EX extern sound card.

I am quit new to this and do not know much about "electronic stuff" ...

regards bre

Please give more detail as to what is not working. Are you saying you aren't getting reverb into the Edriol?

I think the Alesis reverb function because the red lamp is on.

I connected the guitar to the Alesis right Input.
And connected the Alesis right Output to the Edirol sound card input.

But I hear nothing ... no sound ...

You'll have to troubleshoot this by process of elimination (e.g. devise a test for each component in the signal chain, independent of the others, to find the problem or problems.

There are a couple of things you can check easily to start. Are you adjusting the input and output controls on the alesis? Start with the input control. When you play your guitar, you should be seeing a green level indicator if the level is correct. If it is yellow your signal is too low or not getting into the alesis

If you are getting signal in, to see if the alesis is outputing signal you could try connecting it to another piece of gear like a guitar amp. Just be sure to start with the output level all the way down and bring it up slowly so you don't overload anything.

If you get sound to the guitar amp, your problem is probably not with the alesis and may be a configuration issue with the soundcard.
 
Hi!

Thank you for the answer.

I have tried the things you mention but ther is still no sound.
I have a red lamp going constantly, which change to green only when I select the "FX" or "Med Halls".

For what purpose do you use the "Defeat" channel?

Is there any hidden power switcher?

The lamp should not be red all the time. Is the input control turned all the way down (left)?

The defeat jack if for hooking up a footswitch to toggle the reverb on and off. Even when the reverb is switched off, the unit should still pass the dry signal.

Have you read the manual? It explains all the controls. You can download the PDF at http://www.alesis.com/microverb3.

There is also a reset function described on Alesis' website under the FAQ tab. That might be worth a shot.

Unfortunately I have no manual and on the site, you linked to, it is written "this product has been discontinued"

The Microverb does not seem to respond in any way.

Why are you plugging the guitar directly into the unit? It expects a line-level input (which you're not giving it) and there will also be an impedance-mismatch going on. At the very least, you should have a DI box between the guitar and the unit.

Have you checked how your gain set on the Edirol?
Have you checked all your cables?

How do you actually have the Edirol configured? Are you monitoring through software, or using the 'Direct Monitor' feature with the pot on the front to adjust the level?

Have you tried cutting the guitar out of the equation and running the unit in a loop from the interface (i.e. play something out of the interface outputs, through the Microverb and record back in through the interface inputs)?


I don't quite understand why you would want to record direct from a guitar with reverb on the way in anyway. If you do want to use the reverb unit in your mixes, I would recommend recording everything dry then running selected tracks through the unit in an effects loop (as described above) once you're mixing, otherwise you're stuck for good with the wet signal you record. Also, its worth noting that reverb plugins on the computer are likely to be of higher quality and just generally better (not to mention less hassle) than this unit anyway... just a thought!

I agree that running the guitar through the reverb is not the best application but it should work just fine. The following is from the manual

"CONNECTING TO INSTRUMENTS, MICROPHONES
The Alesis MICROVERB III has high impedance inputs that are ideally suited for use either with instrument pickups or line level signals".
 
I have recently bought Cubase and started to make music.
I'm originally playing the drums and don't know much about amplifiers, and I do not have the disposal of any.

I try to make music basically with the midi, but I want to ad some guitar track to it.
I can of course plug in the guitar directly to the Edirol, but doing so you do not get the right feeling or inspiration that I need in order to play.

So that's why I try to use the Microverb between the guitar and the Edirol sound card.

Bre, if you look just above where it says "this product has been discontinued," there are 5 links, one is "Docs & Downloads." The link for the manual is there.

Also, under the "FAQ" link is the procedure for resetting the unit.

Hi!

Thank You Erich,
I found the manual and hope it can help me to resolve the problem.

Merry Christmas to all :)

Good deal, I hope you get everything working.

What is the history on your microverb? Did you buy used (e-bay etc), or was it a hand-me -down? Was it working for the previous owner?

Merry Christmas to you also

The Microverb belong to a Friend of mine who bought it new several years ago, but he did never use it. So it is practically "new" ;)

What I found in the manual is that the Power requirements are: "9V AC,
5 Volt Amps External transformer, UL approved and made in USA".

The adapter I bought here in Sweden is made in China (of course).
You can select among various Volt, and I have selected 9V.

But the Amp is 1000 mA, and I see no info about "5 Volt Amps".
Could this have to do with the problem?

What does UL mean?

On that same product web page, over to the right, it lists the adapter specs as 830mA, so 1000mA should be fine. The only thing that is not listed there or in the manual is the adapter polarity. If that is backwards, you could fry the unit. Since you are seeing a power lamp, I think you are OK.

Do you have any other equipment that you could hook up the alesis to just to see if it is passing signal? Were you ever able to get the lamp to be yellow (instead of red) with nothing at the input?

Once you establish that it is working correctly then you can move on to interfacing it with the computer.

that means it's an ac not dc adapter...

ul stands for undewriters labratories... they are the people responsible for the testing of all the shit that comes into the states...

Hi Again Erich and others!
I just write a line to inform you that I finally found an adapter that function, the third one I tested. The only difference is that on this one it is written 9VA and maybe this was crucial.
Thank you once again for the help :)
