Yes, we're working on it.

A small favor- can you save your current DSP configuration as a preset in the perfect tune app and send the file to us at maestro.support@idatalink.com ? We'd love to see how you have it set up. That helps us build a case to fix the firmware.

I emailed the preset file to the provided email address. Let me know if you need anything. Keep in mind that i haven't tuned the system yet so most of the settings are default.

The master slider volume is set at -6dB (default 0 dB). I've found that lowering it by that much removes most of the hissing noise, bad noise floor in the output signal. It's a balance between getting enough volume output and not having a bad hiss.

For reference i'm using the Audio Control LC 6.1200 amplifier with Focal 165 AS3 3-way component speakers (passive crossover) at the front and Focal 165 AC co-ax speakers at the rear. The subwoofer is JL 8w3v3

Let me know if you need anything else.

I got your file, thank you. We have updated the live firmware to allow you to set your input gain. If you would like to try this to fine-tune it and try to eliminate the hiss, it's up and ready to try.

Dara,
I tried the new official Mustang Maestro firmware v1.6 that was posted. It's now giving me an option to select input sensitivity as either 3V, 3.5V, 4V (default), 4.5V, 5V when flashing the firmware using the Weblink tool. I flashed the firmware 3 times by selecting the input sensitivity option as 3V, 4V, 5V.

Even when selecting the different input sensitivity values when flashing, i couldn't notice any difference in the output gain volume or noise floor. It was the same and i was still having the noticeable hiss when volume is at level 0.

Where are your gains set on the amp?

The gains are around 50-60 % of max.

When resetting the input sensitivity on the DSP you also have to reset the gains on the amplifier. Always.

Give it one more re-flash. There was a problem with how the update was posted, but it should be good now.

And as Cathul mentioned, you would need to re-set your gains after updating to level match and that should help the floor noise.
