+1 I have a HP filter @ 5Hz that I cannot edit. Most of IT is not visible in HFD so I have to measure on amp output.

My experience of updating to v1.3 firmware of two FA253. First one was flawless. Second one got "not in bootloader" error and i had to restart it, then it went ok.

For my FA123's this firmware upgrade resulted in a significant output level increase of the NC100HF relative to the output level of the NC122MP channels. The configuration files had to be modified to compensate for this.


The release notes of the v1.3 firmware mention:
- Gain correction: when maximum input level is aplied to XLR (6.15Vrms) or RCA (2.18Vrms) or SUB (50Vrms) or digital (0dB), the DAC will drive the connected amplifier to its maximum power in 8Ohm load

The output level increase will be different for other FAxx3 models, so you may want to check the frequency responses of your system after the upgrade with the v1.3 firmware.

In the case that you use a combination of FusionAmps with different output powers you may get similar issues after this firmware upgrade.

^Yep, with Fw 1.3 I noticed roughly 6dB increase in tweeter spl level, board FA123.
New gain settings helped to get 3dB more "sensitivity" because I used some of the added gain to heavier eq of the tweeter.

Update went easily for both units. I forgot to check if power management settings had changed with update.

I've inadvertently created an 85Khz filter that I can't edit. It's broad and effects response at 10Khz.

^I have had similar problems too.

It is wise to save a working preset with a different name to serve as backup copy. Then you don't have to start again with an empty table.

Default Measurements in HFD

I’d very much like a start/stop frequency control on the measurement function in HFD.

When measuring tweeters, it would be really handy to be able to set the sweep to start at say 700Hz, to avoid blowing the driver.

A workaround is to add a highpass filter before measuring, but having a starting frequency setting would be a better option.
