Yamaha EMX512SC

I regularly daisy chained 3 8 ohm wedges off the monitor channel. I did this for years and years with success. There is one "Aux send" on this box ( It really shouldn't be called that, but they call it that) and I assume they are referring to the Mon out, which you can hook an amp to. I don't know how that will help gt a separate mix though. We never tried. We put 3 wedges on the monitor channel, 2 mains on the main channel and used the L Mon out for a power amp and a sub.

Are you saying you ran three 8 ohm cabs off one of the power amps in parallel? That is 2.67 ohms BTW

Are we talking about the same head? There is no Aux send anywhere. There is a send for the FX for using an external FX unit then bringing the return back into one of the stereo channels. That is a fairly normal Soundman trick. I had not thought about it until you said something about two separate monitor mixes. If one did not want FX at all he could use the FX for a separate monitor mix out to a power amp or powered cab. There is a monitor send out and a L/R mains send out but no Aux send.

Have to admit what you're trying to do is a little confusing. Sounds like you want to use the second unit to run more monitors but also have the second unit mixer inputs into the mix. But you don't really need the extra inputs. So couldn't you just use the monitor send to the second unit?

I have an emx68s. It has the power amp inputs. I was looking to trade to the 8 input 512 but I noticed it didn't have them. I use them to take advantage of the powered sub crossover. We use the main out into the sub and HP back out to the aux in. Kind of annoying Yamaha didn't put the aux inputs on the 512.

But if all you really need are some extra monitors seems like a powered monitor(s) using the monitor send would do the trick.

FWIW I also use an older Mackie 808m and it can handle 2ohms so you can run 4 monitors of one amp. We've done it on numerous occasions.

Well let me further confuse you. :D

I'm really not trying to do anything. I'm just thinking out loud. I came into a second one of these and was thinking about the possibilities. As it is right now though I do have an added need for an additional monitor in my band but the Yamaha cannot do this on its own. I will come up with a solution prior to our next gig. More than likely we will run a powered monitor for the 3rd unit.

The rest of this is just all conjecture. It is a shame Yamaha did not include the power amp inputs on this head as you could take use of two units fully if thay had but they did not so there you go.

Like I said before I have been using a Shuttle 9.0 for an additional power amp as I have two of them.

What would be cool is to have two MarkBass F1's Velcro'ed to the top of this thing. Then you are talking about four 500 watt power sections and very little weight. Then pick up a small mixing board to allow for more channels when the occasion rises.

We use Monitor out to drive a set of powered monitors if necessary.

If you found an old emX-5000/12 or 20, you would find that it has a much more robust feature set particularly in the i/o area. Same power amps I believe. 250 into 8 and 500 into 4 and you don't go below 4 lest you like the smell of burning plastic... Never done it myself but I've heard anecdotally that sub 4 ohm loads on these boards is asking for trouble.

I've used my 5000/12 Aux outs to drive additional monitor sets using my guitarist's 512 as a power amp. Not optimal but it did save me from carying a power and eq rack. We try to spread the carry around as much as posible in that band so we can get creative on the mix and match. Wish I could get them to use my Presonus/QSC rig but that isn't going to happen...

The mic pre's in the 5000 series are a large step up from the 512 as well.

I thought I explained it clearly up there. I will try again. I used the L Mon out to a power amp to a sub. The specs on the box say there is one aux send ( although I admit I can't find one, not a proper one anyway). I assume they mean taking a line out, via the L Mon out to a power amp and then to some monitors or whatever. This will NOT get you a separate mix though. It is controlled by the Monitor channel.

Yes it is the same unit. Yamaha EMX512SC. Yes I ran 3 8 ohm speakers off the MONITOR channel for years and years with absolutely no issues. Probably wasn't supposed to, but I did and it worked fine. It would probably work better if at least one of your monitors was 16 ohms.

I have owned both ... and IMO, I'd rather have the Carvin. Both were rock solid reliable, but the Carvin has two separate effects processors, plenty of routing options, and is, IMO, a better built unit.

IME built in FX on ANY unit are marginal at best and I would never base the purchase of a powered mixer on what kind of built in FX it has. I have ( and still do) use a lot of Carvin stuff. My bass cabs are Carvin and I use an old RL1000 for power ( preamp blew out long ago). The cabs are OK, but they do not compare to most other high quality cabs. ALl their speakers are now made in China by the way. I have had a few of their power amps and I have had them fail. A band I was in years ago had a Carvin powered mixer and while it never failed, it certainly didn't come across to me as a better built unit then the Yamaha. In fact I have never heard anyone make such a claim until now. I have a Carvin TL60 that is hands down the best action on any guitar I have ever played and I own vintage Gibsons and Fenders. I used to have an LB76 that was a slick 6 string bass too. Personally, I love their guitars, but I don't care much for any of their other stuff and I surely wouldn't pick one over a Yamaha. That EMX512SC is a nice, solid little unit.

The Carvin unit definately has the feature set trump card over the Yamaha. That being said the Carvin gear (both instruments and amps) I have crossed paths with through the years has been poor quality. Not saying all their stuff is but they have pumped out some less than stellar stuff. The FX on the Yamaha suck but I do use them sparingly.

I actually have quite a bit of experience with the Yamaha as I have been using two seperate units for some time now. I use one at my Church gig and one for my band. The Unit we use at Church I purchased for the Church a while back. The new additional unit could just be backup I suppose and I could use the power section if I need it. It could do so much more if there was a set of power amp inputs.

As a side note I did wire one monitor cab for series to allow for two 8 ohm cabs series then wired parallel to one 8 ohm cab for a total of 5.3 ohms at my Church gig. So far this has worked well for running three monitor cabs off the 512 but I'm not sure I would want to do that with my other siuation.

I must be mistaken then. Obviously my personal experience must have been dreamed, and the until now reliable Carvin RX1200 I have must be a POS.

Dreamed? Come on man. People make the exact same claim about Behringer as you are now making about Carvin. And I have personally witnessed both Behringer mixers I have come into contact with commit suicide. Was my experience dreamed?

Some people loved the Edsel. ;)

You're a funny guy ... :rollno:

Who the hell said anything about Behringer? I just don't understand how someone can relate a personal experience and be told that their experience is invalid. But such is the way of pedants ...

Show me exactly where anyone claimed your experience was invalid. It's just as valid as all the guys who love their Behringer gear, which is coincidentally just as valid as all the guys who have watched their Behringer gear self destruct. If the analogy is lost on you I don't think flipping out subtle insults is helping your case any.

Ok back to the gear.

I did notce the Crown XLS1500 would be a good addition to a head like this Yamaha. For those who are using passive speakers and aree on a tight budget. Still keeping things light, 2 space rack shallow rack should get it I believe.
