Trying to upload the crossover. Got the following error message "NO RESPONSE, CHECK YOUR CONNECTIONS OR UPDATE THE FIRMWARE". There is green LED from the board. PSU not connected. USB to COM3 Bridge shows up as a device. Need new firmware? Board corrupt?

@JazzJack if you send me an email at info@zoudio.com I can send you a I2S user guide. It explains how to disable the incoming I2S from the BT module and how to hook up an external I2S source.

Update:
There is new stock of the AIO4CH and the plate amp extension kit!
New orders now ship out within 10 days.

And an update on the 2.1 software:

It has been more difficult than expected. I was working on a version that switches between two UI modes and two different firmware files, but that was not smooth enough in my opinion. I am now working on an improved version with the same functionallity but less clutter. Hopefully more information soon...

2.1 with mono sattellites is already possible currently, please refer to previous discussions :)

As far as 2.1 with stereo sattellites: yes, still working on it. Its taking way longer than expected because it requires quite an overhaul in the communication structure.

I attached a preview of the new GUI. Besides the functional improvements, I am experimenting with some visual improvements, any feedback is welcome :)

Here's an example of the Room EQ Wizard export examples, there are plenty of different export versions available but I think the EqualizerAPO could be one really popular format that would be nice to get export directly into Zoudio.


This way it would be simple to first measure with REW - create the desired filter in there and export a file that could be loaded directly into Zoudio. REW has a pretty good filter creation tool and has plenty of horsepower for quite heavy filter creations.



example.txt



Filter number : ON/OFF: Filter type (PeaK) : Frequency : Gain : Q


Filter 1: ON PK Fc 31 Hz Gain 6.6 dB Q 1.41

Filter 2: ON PK Fc 62 Hz Gain 3.0 dB Q 1.41

Filter 3: ON PK Fc 125 Hz Gain 0.4 dB Q 1.41

Filter 4: ON PK Fc 250 Hz Gain -1.1 dB Q 1.41

Filter 5: ON PK Fc 500 Hz Gain 2.1 dB Q 1.41

Filter 6: ON PK Fc 1000 Hz Gain 2.6 dB Q 1.41

Filter 7: ON PK Fc 2000 Hz Gain -2.7 dB Q 1.41

Filter 8: ON PK Fc 4000 Hz Gain 0.5 dB Q 1.41

Filter 9: ON PK Fc 8000 Hz Gain -3.4 dB Q 1.41

Filter 10: ON PK Fc 16000 Hz Gain -4.0 dB Q 1.41

Just want to say thank you for great customer service that Zoudio has. My board didn't work. Jesse tried to debug it via remote desktop. We couldn't solve it so he sent our a replacement board free of charge and postage. DHL & USPS took about 45 days to deliver the package. I was able to get it working and it sounds great! I think better than 3eaudio 4-channel amp & DSP cards which I also have.

Again, thank you!!!
