Btw. "popular speaker mapping options" would include 5.1 for me with the RMC-1 acting as a crossover for my active 3-way DIY speakers... How about 48 outputs? Then you can have 16 active-3 way speakers! Hello everyone! Hey Jim does this mean it's going to have active DSP xover option with modular/mapable outputs? I've been talking about such a beast for years... |

Imagine you could design a line of amps for active xover 2/3 way using different amplifier topologies for each section. Nice class A for the tweeter, class A/B for mid and class D for sub in a 3way in one amp chassis. You could use speakon 4 or 8 ring/pin connectors. Another thing I can't help but notice is the amount of PCB and backplate I/O space XLR connectors take up with these many channel pre/pros. Why hasn't any audio design outfits considered using MINI XLRs!?! This would solve a lot of issues with backplate I/O density and PCB real estate.  |

Oh wow it's going to be using ADI Sharc DSP!
RIGHT ON!
From Cirus Logic to TI and now ADI! Should have gone ADI from day 1 Emo/Jade.
I wonder how much of the TI Dirac code can be salvaged to Sharc...
The miniDSP guys have Dirac working on Sharc BTW.

Are you assuming that MiniDSP wrote the code? I would think that Dirac would own that I.P. for the most part. Somehow, I doubt Dirac running in Sharc DSPs will be a big deal. |

I've been talking about such a beast for years... I was kidding..... but would be nice. Outputs might be mappable - but active xover? I highly doubt it. I believe the Datasat RS-20i can do crossovers using assignable outputs ..... but it's a clearly a different price point. I'm content with the RMC-1 being a processor without being a full blown speaker management system. |

Nice class A for the tweeter, class A/B for mid and class D for sub in a 3way in one amp chassis. You could use speakon 4 or 8 ring/pin connectors. 3 different topologies... in the same chassis? That's....... creative. So question for you: "You're in a desert walking along in the sand when all of the sudden you look down, and you see a tortoise, it's crawling toward you. You reach down, you flip the tortoise over on it's back. The tortoise lays on it's back, it's belly baking in the hot sun, beating it's legs trying to turn itself over, but it can't, not without your help. But you're not helping. Why is that?" |

Hopefully there is a solution for us guys who run front and rear subs....

I have the AVM 60 and the video lag is pretty bad.

I have the AVM 60 and the video lag is pretty bad. You can manually adjust lip-sync under each HDMI input within the AVM 60 to compensate for display video processing delay. I'm surprised the processor doesn't support automatic lip-sync if enabled in the TV/display settings. |

You are not the only one, but I highly doubt that this will be included. Too small of a target market. I think if cost wasn't the biggest factor, there would be a bigger market. Figuring that adding that capability could add thousands.... thousands on top of $5k certainly doesn't help.... |

I'm surprised the processor doesn't support automatic lip-sync if enabled in the TV/display settings. There's no such thing as automatic lip sync anyway; automatic as in the audio and video are continually adjusted on the fly to maintain lip sync. At best, the display reports a fixed value back to the processor and the audio is always delayed by that amount. Sometimes, displays report 0 or the same fixed value for all modes, e.g. even a game mode that you would expect to have less delay. Finally, if your broadcast TV source is not synced properly, the processor has no idea. -tm |

Our favorite techno-elves could design worthy adjustable crossovers in a module. Then based on the modular concept of the Gen. 3 X amps, have a crossover module (or two) and then two or more amp modules in one chassis. You could order it in two-way, three-way, and four-way configurations. It wouldn't be a MONO monoblock. But it would be one chassis per speaker. By making the crossover points adjustable, you can either build or modify your speaker to not have an in internal crossover. Then adjust the crossover point to compliment your speakers best blend. The complete answer to those wanting to active Bi-, or Tri-amp. |

That's an interesting idea...... but not that many people really would bother to use a Class A amp for the tweeter... and a Class A/B amp for the midrange. or, to put that differently, most of the people who would do that want to be able to select each amplifier individually anyway. (Personally, if I was convinced I could hear the difference, I'd use the "better" amp for the mid.... but the difference between a modern Class A amp and a Class A/B amp is usually pretty small.) As for subs.... we sort of have that already.... since most subs already have built-in amplifiers. Our current XPA Gen3 amps are modular, with each chassis holding anywhere between 2 and 7 one-channel modules. And we'll be coming out with two-channel modules soon (each of those fits in one slot, but provides two independent channels of amplifier at lower power) That will let you have anywhere between two and seven big channels, or between two and fourteen small channels, or any combination, in a single chassis. As for having too many connectors on the backplate...... there's a common solution for that that's used on lots of pro equipment. Some folks call it an squid.... basically you have one big connector with lots of pins, and a bundle of short wires coming off of it, with a separate connector on the end of each. (You see this a lot on digital mixing consoles, where a dozen separate wires with individual connectors are all attached to a single 25-pin connector.) It has the benefits that, for example, if you aren't going to be using any balanced inputs, you simply don't plug in the bundle of balanced input cables. However, the down-sides are: 1) they're messy 2) they're one more thing that can go wrong 3) they're one more thing you can lose 4) sometimes the bundle of wires is bigger and heavier than what it's attached to 5) since it's a bundle, you either attach the whole bundle or none - so, even if you only need one digital input, you've got a dozen connectors hanging there Audio connectors have always been a tradeoff between convenience, cost, robustness, and space (there are lots of different ones that perform quite well). XLRs and RCAs are simply the standard - which is why we and everybody else uses them. Imagine you could design a line of amps for active xover 2/3 way using different amplifier topologies for each section. Nice class A for the tweeter, class A/B for mid and class D for sub in a 3way in one amp chassis. You could use speakon 4 or 8 ring/pin connectors.

Because you're too busy trying to catch the rabbit that you're sure is somewhere nearby. But the real question is why you messed with the turtle in the first place..... Do you just not like turtles.....? Or is it on your dinner menu (perhaps with a side dish of stewed rabbit)?  Imagine you could design a line of amps for active xover 2/3 way using different amplifier topologies for each section. Nice class A for the tweeter, class A/B for mid and class D for sub in a 3way in one amp chassis. You could use speakon 4 or 8 ring/pin connectors. 3 different topologies... in the same chassis?
