Topic: Adi 2/4 Pro volume jump issue

Hi, why is Adi 2/4 Pro have volume jump (louder) while changing NOS filter to other filter? is this a bug?

I use NOS filter as my default filter, but most of the time the volume are lower, if I change to other filter it will jump back to the normal volume, then I will change back to NOS filter again then it works normally.

Doesn't happen here or for others. You need to check your firmware version and - in case it is up to date - provide more details how to recreate this, and how many dBs the volume difference is.

Re: Adi 2/4 Pro volume jump issue

The volume number shown remain same while the volume jump. I think if you try using NOS as default filter, and switch off and turn back on or change to other device for playback, then switch back to adi2/4 pro you will notice the issue when changing the NOS to other filter. The volume jump louder around 10db estimated by ear.

the firmware are always up to date.

Re: Adi 2/4 Pro volume jump issue

Your firmware is FPGA 71, DSP 32?

Did you update the firmware yourself from an older version 67/26 or below? If so did you perform a reset?

Attention: After the update reset the unit: in power off state press and hold upper encoder 1 (B) and the VOL key (not VOLUME) while turning the unit on. The display will show ‘Reset Done’.

This reset is not necessary when updating newer versions.

Re: Adi 2/4 Pro volume jump issue

The firmware is FPGA 71, DSP 32. I always check the latest update of firmware and still waiting for the latest remote app for ADI 2/4. it's not firmware version issue.

When I purchased the product, the firmware version I think is like FPGA 70, DSP 30/31? but I'm sure its not 67/26.
