Jule Amps Monique Part 2.

Status
Not open for further replies.
Finally got around to trying out Jule with my new Crest Pro-Lite 2.0 Preamp thru 2 Bergantino AE210 cabs. Sounds great as expected. Almost 2000w and approx 10lbs.

I gave it a good spin as I just got back from a short vacation with 2 new basses that needed some love (MTD 535 and a Spector USA 5).

Man, I love this Monique preamp in any case! I paid $349 for the Crest new on eBay, so add that to the pretty expensive Monique, I an still JUST into SVT or Mesa M9 price territory! Not bad! Props to audiosavings.com.... They were inexpensive and shipped lightening fast!

In any case, the Crest seems to be a great, transparent and powerful amp and it works well with the Monique.

I THINK I prefer my D-180's power amp with Monique over the Crest, but that might just be in my head due to all of the power tubes! The Crest is 1/5th of the weight of the D-180, it is a keeper!
 
Got to play check out Monique into a Crest this weekend. Sounded great to me (thank you Ryan).

It's tough when all you have is great gear. ;)

Jule,

I have a quick question, regarding the matching of Monique to a power amp: I have a two channel power amp with input impedance on each channel of 20 KOhms. Presumably if I went only into one channel Monique would see the 20 KOhms, but if I used both channels (unbridged) by connecting them in parallel, Monique would see 10 KOhms. On the other hand if I bridged the channels Monique would presumably see 40 KOhms. Firstly, am I right about the loads (combinations of input impedances), and secondly how compatible are these input impedance configurations with Monique? (I also have two IP series cabinets, which have input sensitivity of .70 volts (-3 dbv), but from what I've read on here they should be fine with Monique.)

Thanks,

Jim

I hope this hasn't been answered elsewhere, but this thread an it's predecessor have well over 1000 posts...

Balancing doesn't typically put the two inputs in series in the way you're thinking, but there are a few different ways it can be implemented. The impedance will also change depending on whether you use a balanced or unbalanced connection. What specific amp do you have?
 
Well stated Mr. Wind.

The "specification" that is most important is the Input Sensitivity of your amp. As you said, the (wonderful) IP's are asking for .775 volts RMS. So are a whole lot of other good amps. Monique as she sits today is optimized for that Input Sensitivity. She is also optimized for a 10K input impedance from the Line Out and a 600 ohm impedance from the Balanced XLR Out.

For you and me in the Bass World, the impedance can and will make a difference, but not as much as the Input Sensitivity.

Warning! Now leaving the Bass World for that of the geekazoid. My advice is not to read any more of this because it will not help you play any better. :)

A generalization I can make about impedance matching connections is that 1:1 matching (such as 10K to 10K or 600 ohms to 600 ohms) is best. By "best" I mean that stuff gets transferred across the connection like we want it to. "Stuff" includes the audio and the playing characteristics.

To continue the connection generalization, if there has to be a mismatch (like your ~10K passive bass pickup to a 1Meg amp input) it is best to go from low (10K) to high impedance (1Meg). This provides more current, which is what does the work. This is why piezo pickups (extremely high impedance and low RMS voltage out) need buffers to sound as good as they can into a normal amp. Piezos (un-buffered) go from HI to LOW impedance, so there is less current to work with - stuff gets lost.

Your example of parallel/series output impedances sounds good on paper, and is entirely reasonable, but that isn't how it actually works. The description as to why it doesn't work is boring beyond belief, so I will spare you.

In all this, I apologize to all the EE folk out there for my generalizations of something that you spent semesters learning in so much more detail.

Let's just make music.

Has anyone used this pre with a Crown XTI series. I have a XTI2000 that I would like to use with this pre. The input on this amp is XLR. If I go TS from pre to XLR to power amp am I going to have any issues with the line out from the pre being unbalanced. I am ordering next week and per my conversation with Jule was that he did not know what the result would be and of I would have to use another amp.

Where's Skies?
He does this.
 
My new setup......

Monique
Cheap Crest power amp
2 used but mint Bergantino AE210s
A couple of nice basses
Zero effects.

Absolutely kills for any size room.

Baird, that is one saWEET rig! Very very nice!

I have been putting together a new rig as well. Crest CA9 power amp driving a stacked pair of Genz Benz Uber 212 cabs. The only thing missing now is a Monique (rackmount version), and I plan to order it the first week in November.
 
Baird: how does your Monique/Crest combo compare tonewise to your Mesa D-180?

I THINK the D180 sounds tubier than the Crest when i use just the D180 power section with the Monique, but I might just be hallucinating.

Using the D180 as a regular amp against the Crest/Monique, the D180 is tubier.... But the Monique has much better articulation and cuts so well.

The D180 sounds great.... As did my Mesa M9, GK MB Fusion, Ampeg SVT, etc. The Monique IMO/IME sounds better than any of them.

P.S. the only mistake I made was buying the super cool looking bird cage model. Not as functional as the rack version for most.

Thanks Baird for those comments. Much appreciated! I liked your comment "The Monique IMO/IME sounds better than any of them." Btw, the bird (aka "dove") cage definitely wins the "cool look" award! I'm only going with the rackmount version for functionality.

Yes, it is much better to hear from players who can tell us for sure. The Crown XTI specifications say 1.4 volts, but they do not tell us if it must be truly a balanced signal. It might also take a 1.4 volt Single Ended signal.

I have found that just because something has an XLR jack that doesn't really tell us much.

Very recently Monique was "enhanced" with the ability to put out up to +4db (1.25 volts) with a minimum input (and the EQ zeroed out). This is from the Line Out 1/4" jack. The Balanced Output (truly balanced) also goes up 4db to -10db (.775 volts).

Because a whole lot of folks are very happy with the original levels, they are still exactly as they were. To get the extra 4db (to drive more amps) you just pull the Line Level knob toward you.

Still does not answer our question my friend. Sorry.

No mistake. Just get yourself a rackmount too. :)
