The New Hypex Fusion Plate amps

Hey bavmike don't let the POS naysayers rain on your parade. What I have seen is people with a no quit attitude can get these things if they get creative. The class d amps I got were "not available" either. What myself and others found out how was the manufacture had a minimum buy of 20 units to qualify for" bulk" sales. Ten of us pooled together and ordered. Within a couple of weeks we each had a pair. You know the kind that lurk around here. Constantly want to seem like the authorities and build there own egos. This forum is there only life to finally make it! Thanks forth interesting post. I wasn't even aware.
 
I've been using three pairs of 3-way FAs for 8-3 years. I have not noticed need for remote or oled. Preamp/source is volume control and one set of settings is enough.
FA123 and 253 don't have fans but I've had no issues with heat or (soft)clipping, power is on 24/7, standby activated. Home use, not PA.

About availability, here in Europe we have many retailers so units are available all the time.

etc.
 
that leads to the question: is this a common defect?

is a new fa253 fully compatible with the older ones? i have the V1.5 firmeware product range in my other speaker
I had complete modules go out but never your error. So I would say it's not common.
I would contact Hypex about the issue and if it's known. When it's a problem with the powered amp it could be changed pretty easily - it's just a matter of cost if it makes sense.

The new ones are fully compatible, same software, same filters etc. just a few options more.

Thanks! I assume the remote kit (not the display kit) will do the same?

What is still not clear is if the indication will be per speaker, e.g. if one speaker overheats, will it indicate just on that one, or both will indicate overheating?
I have the remote in only one unit. Personally think it's enough. If the other amp overheats it should shut itself down so you should notice. Never overheated any of them so I don't really know how it looks

I just got 2 Fusion amps and I'd like to connect the master with the coaxial spdif out on my streamer, then daisy chain the slave via aes. Cable length will be something like 5-6 meters so I'd prefer aes.

From what I read in the manual I think this should be possible but it's not 100% clear to me.
Can somebody confirm this works, before I start buying cables 🙂

So spdif in, aes out

This works. I got miniDSP SHD -> SPDIF coax (3 meters) -> Hypex FA123 -> AES (5 meters) -> FA123.
 
You will get the sound but usually one box is the master and the other the slave. Signals from the master regarding volume or present changes are only transmitted via coaxial spdif. This might be ok if you put the remote kit in both speakers but if one gets the IR signal and the other doesn't you have a problem as they are out of sync now.

So interconnect between the speakers should always be coaxial spdif.

This is also in the manual. I attached a screenshot.

Good news: According to the manual up to 25 m cable length is fine.

@mysterious and @CoolJazz I forgot to mention that both of my FA plates are in master mode. That way the volume is controlled in the miniDSP before going to the plates. With digital connection that does not introduce any unwanted noise and works very reliably.

The screenshot in mysterious post is related to using a remote and there, if I understand it, I have never tried it, you can use spdif to relay the volume information from master to slave plates, but audio goes with aes, so two cables!

The screenshot in CoolJazz post is related to daisy chaining in general and shows how inputs are routed to outputs. If the spdif comes from a digital preamp, I would suggest that you do same kind of setup than me: both plates in master mode and volume control in the preamp.
 
My FusionAmps are only for the active speakers and their crossover+tuning, I never change their preset. My miniDSP in the front is for room correction and other boosting business, and I use presets there. I also got subwoofers that I can activate/disable by a preset in the miniDSP. A digital signal has enough s/n ratio to handle cascading DSP processors. This configuration gives me more flexibility and ease of use than hooking all my sources directly to the FusionAmps. I spent much time planning this audio chain.

If you need to be able to control volume and FA presets conveniently without a separate preamp, remote control and master/slave configuration is the way to go.

Like Jukka I use a preamp (my AVR that is also slave to TV via eARC), FAs are both masters via RCA. This is easy for the family, they don't even notice that main speakers are active. Same with my minidsp-controlled active mains.

A dedicated heavy user might operate the system made for only herself and master a system with any kind of contols and chaining she wants or prefers. Ideal would naturally to use only digital chain. Spl volume control type and position in the chain is debatable, both digital and analog have caveats.

In my setup both control signal and audio go over spdif.

If you attach a laptop with HFD you can see that the master actually tells the slave to switch input/volume/preset.

As this is all digital I don't see any benefit from using AES unless you need more than 25 m of cable length.


If you don't change anything on the w.r.t. volume/preset/input there is obviously no need to even have the spdif connection.
 
I want to avoid doing digital to analogue twice. That's why I want to go in to the fusion amps digital.
I totally believe i will not hear the difference but if you can avoid the double DAC loop, why not use it.

Sanne with the cables, why not use aes when i can and have peace of mind.

Volume wil be handled upstream by Roon so no issue there
 
The tweeter channel of my Hypex FA253s continues to hiss for a few minutes after a cold start. Recently I noticed that during this time period, the movement of the woofer modulates the aforementioned hiss from the tweeter.
What could be causing this?
