I would think your amps would play whatever sound you put into them.
As long as your computer is outputting it?
They do. The amps drive the speakers. The speakers sound fine.

Quote:
Can you hear a difference in the sound while playing music?
I don't discern and difference with or without the EQ.

Where is the music connection to the amps?
Optical connection between my Mac Pro and the Master Hypex FA123. Music plays fine. I can also easily hear the REW sweep from which the software does its measurements.

All of the seems to work fine.

Do you have to turn on the EQ settings?
You upload the EQ settings from the Hypex software (running on a Windows laptop connected via USB to each plate amp in turn) in a way similar to how one uploads crossovers for multiway speakers.

In fact, the manual states that once uploaded the EQ setting take place immediately, nothing else to do.

Something strange at work. Or maybe I've missed something.

I've set and uploaded the EQ settings to the amps as directed in the manual. They should just work at this point.

Drafting an email to Hypex. I'll report back with an update.

Are you saying That the EQ is done in the amp or is it done in the software In the laptop?
Because your optical output is bypassing your laptop?
Sorry for being a little confused.

Steve,

No problem.

Hypex amps come with (Windows) software the enables one to configure all of the amp's DSP (EQ, crossover, even DAC) settings (as well as a bunch of other things).

I connect a Window's laptop to each amp in turn via a USB cable.

Then I open the Hypex software press the EQ button on the main page to open the EQ window.

Within the EQ window one can set any of 9 EQ presets to anything one needs.

One then clicks the "Enabled" checkbox and presses the "Upload to DSP" button.

This last step uploads the settings to the amp's DSP.

From that point (even with the laptop and software disconnected, even when you turn the amps off and on again), the now uploaded EQ settings reside in the amp itself and should affect any signal sent to the amp and, in turn, the speaker(s).

Just very odd that it doesn't appear to affect the REW measurements.


Note, I only use the Windows laptop to configure the Hypex amps.

My desktop Mac Pro connects to the Hypex "Master" amp by a fiber optic cable. The Mac Pro holds all of my music files. I additionally connect my microphone to the MacPro and run REW on the Mac Pro.

It's probably something very simple.
My DEQ is just as complicated, and sometimes I accidentally altar something? Or its broken?
I then have to go through everything to find out what and where it has happened.
It's usually me accidentally touching a button that has caused it.

Hello DML thread, this is my first post.

I've been lurking in several DML related groups and learning the basics. Bought a calibrated mic and getting started with some measurements.

What lead me to this was first watching the Tech Ingredients video (as with so many others), reading some deeper material in the forums, and then realising that I may have a perfect environment to create a great DML (+ maybe open baffle) setup.

So this first post is to get feedback about the potential of this space. The articles Ive read in the last few weeks suggests that it may be just the ticket. The space is a room about 8m long and 4m wide (haven't measured accurately), with a partition across the room at around 4.5 m, with two big rectangular windows. See photo. The thought is to mount some big DML panels in the windows (0.85m x 1.3m), and if that is successful, to look at using the lower part to house some open baffle drivers.

(Hoping the image link from google photos works)
