Been setting up my filters using measurement and EQ filters in REW and directly editing the filters in HFD. The "load filters option" is grayed out, even though I have it connected to the amp, FA503. Everything seems setup correctly but I must be overlooking something. Any suggestions what the problem could be?
I never used one.
When doing filter development, I set the soft clip limiter to 10W for large woofers, 5W for small woofers/mids, and 2 W for tweeters. All my filter measurements are done at about 80 dB.
I should mention that all my Hypex Fusion work has been with the amps set up in their most simple way: I only use analog inputs, and both left and right amps are completely independent, i.e. both are set to "Master".
It seems that when using digital inputs, or when setting them up as "master - slave", there is more opportunity to make an error and go full output to a driver.
So for me, it made sense to skip the capacitor.

I do observe an issue with one of my 253 plate amps. I use them in master/slave arrangement and they are connected with each other via SPDIF. The master unit is conected to the remote control PCB. The master is fed via AES/EBU.
Since several days I am confronted with a situation with no output from any of the speakers and when the master is connected to PC via USB, HFD shows no input level on the VU meter. The meter resides constantly at -72dB (dBu? cant remember). I have the latest FW on both plate amps and have already tried performing a FW update on the master-unit and also did a "restore factory defaults".
Today I have exchanged master and slave and this setup works flawlessly.
I have the suspicion the DIR (digital input receiver) or the DSP of the initial master unit does not lock/sync properly to the incoming carrier.
Is this a known issue? What can be done to "re-enable" the AES input on my fusion plate amplifier?

Hi
Im using a setup with 4 Hypex amps. I have been looking but cant find any info about this...
I would like to be able to control the 3 slave units when the master is connected, is that possible? There is is LOT of moving usb-cable when testing different settings on all channels.

I haven't found a work around for this either.
The USB connection only enables changing the configuration settings.
These devices don't support the kind of daisy chaining of USB for configuration of settings that they do for distributing the digital audio signal from master to slave units.
Hypex support may have a solution. I've found them responsive.
Alternatively, get something like a miniDSP SHD to use as DSP & DAC and only use the Hypex amplifier modules, driving them in analog.
I've done exactly this in one of my systems and it works.

Yes it is a pity you can only connect one plate amp at a time. I still do not understand why multiple units together is not supported. I would think that there must be a possibility to achieve this. At some point in time I was even thinking about creating a DIY device with relais to auto switch USB. And also to be able to disconnect USB during critical listening...
Thanks guys for answers, seems like a simple thing to fix software-wise but then I have to keep doing like before. I might try to send them an email about it.
Hope the low quality USB connectors in the amps doesnt wear out any time soon 🙂

Hello,
it's been over a year since someone's posted in the thread so pardon me for digging this thread up.
I recently got my pair of FA253s' and I've found setting them up somewhat intuitive and easy to do, however this is my first time running something in AES/EBU and the following quirk is bugging me.
I've set up left channel master and right channel slave; both have forced input to AES. Master has been enabled to "volume on start" -24dB. Routing is as follows: from soundcard AES output to left (master) speaker AES input, then AES through to right speaker AES input. They work as intended when set up.
After shutting down mains and later turning them back on in the suggested way slave first then master for some reason 1) the slave is muted 2) level is set to -96dB. I was in the understanding that when slave is turned on first it waits for master for information about level etc.
I've gone through the manual quite a few times during the whole set up process but for some reason I am unable to see a solution to my problem in HFD manual. Please help!

You can email Hypex support. I've always found them response and helpful.
Good luck.
Ah yes the classic user error, my arch nemesis. Hah!
So I did contact Hypex and their wonderful I guess tech person basically explained to me that while the plate amps do accept AES/EBU input, using them in master-slave configuration does require S/PDIF from master to slave for the information to flow properly between the two amps. AES/EBU is for high quality audio only. And my earlier AES/EBU signal route did function as it should with regards to audio, however there weren't any communication between master and slave other than master passed right channel audio information to slave as AES/EBU apparently does.
To quote:
"To my knowledge AES is reserved for the high quality differential audio transfer, and the SPDIF output is a common connection and can be done by any 75 ohm coax cable with tulip connectors. So that is why this choice is made. It can transfer both audio and communication, as the communication is superimposed over the signal. It is not recommended to use SPDIF for audio transfer above 96kHz. This way AES can specifically be used for the higher quality audio signal and has no additional communication frequency added to it."
That knocked the sample rate down from 192kHz to 96kHz but I don't mind, I'm not a little brown bat. Actually I'm not even a cat to be honest. I mean I say that I'm not a cat.
Anyway the setup is working great now and the final, functioning signal route is from soundcard AES output to master AES input; master S/PDIF output to slave S/PDIF input. They also suggested to lock slave input to S/PDIF in HFD just in case.
Hope this helps 🙂
