"Emotiva Audio has announced a new three-channel amplifier based on three of the company’s 600-watt balanced monoblock modules. Originally referred to as the Three.MB, the new XPA DR3M is a balanced, fully differential monoblock amplifier in a three-channel configuration. Pricing was not announced but the amp is slated to ship in the summer." >> Read more << |

That's not what a monoblock is. That's a 3 channel balanced amp - albeit a very nice one!
Also, there's no such thing as monoblock modules unless you are talking about modules inside an actual monoblock amp - which you guys have made several models of before. XPA-1, XPA-1 L, XPA-100, UPA-1. Even technically the XPA-2 gen 1 and 2 could be considered a monoblock in bridged mode.
In this case the DRM-1 would be considered a monoblock amp with monoblock modules but not a DRM-3.
P.S.: I think these amps look fantastic! They don't need the word monoblock to sell them!
They are 600 watts per channel!!

Sounds cool but I'm sure happy I bought my XPR-1's when I did.
Nick I think the monoblock society needs to meet privately about this...😎

Do they share power supply?

They share a common Switching Power Supply. So Hair Nick, are these to be consider to be the "RPA"s to pair with the RMC-1 (and XMC-2)? :-) Casey |

Oh be still my racing heart. Next I need to open a new savings account, because I want two of them.

Are you guys pro-wrestling fans?

Since I asked in another thread and I didn't see reply as of yet I will ask again in here. Any chance of a monoblock technology ebing sold in an actual monoblock? Since the housing could be quite small I would like to see something on the line of Marantz MA-700 or MA-500. I think those would be awesome. The power these put out in a small chassis would make a lot of sense...at least to me.

The marantz ma500 and ma700 were true monoblock designs. Each had its own power supplies, power switch, etc. a lot was stuffed into those little chassis but the 700s sounded pretty nice all things considered.

I don't see why Emotiva cannot bring something similar to those Marantz amps to market. Either a 300 wpc monoblock or a 600 wpc monoblock in a nice small chassis, I am sure either one would be popular. |

is a balanced, fully differential monoblock amplifier in a three-channel configuration.
If TRUE it means 3 each monoblock amps with independent power supplies and totally discrete wiring, with zero interface between channels and simply enclosed within a single chassis (why? did you consider EMI/EMF?). Otherwise it is BS. Welcome to the world of advertising Emo dudes. Nice naming convention  Slated to delivered in the summer............of what year? assuming past practices 2020 or so?

I am sure it sounds nice indeed. I won't say it is not a mono block amp just not a traditional mono block amp.

What makes a monoblock a monoblock? If you're disregarding these amps because they share the same power supply... well, 2 "real" monos can share the same wall outlet, so as long as the power supply in these is sufficient, where is the issue?

copperpipe It's like calling a 2 wheel drive car a four wheel drive when it's really a 2 wheel drive. Then claim that it is 4 wheel drive because 4 wheel drive cars does technically have 2 wheel drive included in it. That's not how it works and that's not what 4 wheel drive means. So by calling something that isn't a monoblock a monoblock, one is claiming that the amp has things that cost money to make that are not actually in the amp....like a SECOND OR THIRD POWER SUPPLY for the MB 2 and MB 3. Power supplies don't grow on trees! Also if a monoblock fails on its power supply....that means you replace THAT monoblock channel. Your other channel remains runnning. If the MB 3 power supply fails, then all channels are out of service. I have no sound on the fronts. If I had three XPA-1 gen 2's monoblocks on the fronts and one fails, I have no problem, I'm still getting stereo sound. I just replace that center when I feel like it. If the MB1 fails, then only one channel is out of service - that's because it's a monoblock while the the MB2 and MB3 are not. Two monoblocks can indeed share the same wall outlet. But not the same power supply. Monoblocks eliminate cross talk. Also when you share power supplies, one channel will produce slightly less power than the other. You can see that from the AP measurements of amps with more than one channel. And even though it's not strictly defined as so, ideally these monoblocks should be in separate chassis per channel. But it doesn't have to be. For instance the Emotiva RPA-2 actually has two torroidal transformers and is a stereo amp.  You could kind of get away with calling it a monoblock because it has two torroidal power supplies and separate blades per channel. However the only niggling factor is that they do share the same power cable - not a huge deal. Emotiva also used to sell a multichannnel amp that also had torroids per power supply (but shared a single power cable). IPS-1. You could get away with calling a monoblock though it does use only one power cable.  If any of those channels failed including a power supply failure, the others keep running and you just slot in a replacement channel. An aside: For instance my DC-1 has dual DACs on it - one for the left and one for the right. But it doesn't have two power supplies so it is not "dual mono all the way" though it is a dual mono DAC configuration. The XSP-1 is fully balanced, however it does have cross talk because it shares the same power supply. The Audio GD HE-1 preamp however is fully balanced, has separate circuits per channel, and has separate power supplies per channel. However they do share the same power cable for the two power supplies. Not the end of the world - you could get away with calling this a dual mono preamplifier - though you can't call the XSP-1 that.  My point is that a monoblock costs money. Because you have to spend money on a separate power supply. The power supply is one of the costlier parts of an amplifier. This results in NO cross talk between the circuits. It means that when one channel is demanding current, the power supply isn't feeding the demands of hte second channel.
