Pre-gain on linked devices.

[WiiM Team]

Hi All,

Thank you all for your valuable discussions.

We've reviewed the pre-gain functionality in multiroom mode and determined that the pre-gain should apply to all devices in a group. We will have an internal discussion to explore the implementation details—stay tuned!

Hi @WiiM Team,

If this is feasible, it would be better to do it on the slave side instead of the master device processing the signal.

The pre-gain value for each WiiM device is stored in WHA. Then the slave device will get that value when creating the MRM. Devices with "Group Pre-Gain (GPG)" turned on will output audio with the master's pre-gain value added.

This allows "Slave A" to have GPG turned on and "Slave B" to have it turned off.
(Of course, the master device will still assign the signal as before.)

I can't think of a use case for this because I don't need right now, but it will give us more flexibility.

But, @hgo58 who is all about "pre", might object vehemently.


Edit:
However, I can't imagine how this feature would work with the addition of MRM's master device deletion feature.

seeing you intervene here and not seeing you react on the threads concerning very serious problems concerning the audio like clipping etc...see the audio concerning all the wiim models and not "needs" concerning only the ultra (it s screen etc, ) like cal microphone or importants beta highly anticipated...
remains astonishing even worrying... or create a great weariness....

I would still have concerns that it “imbalances” the slave device across its inputs so this would surely have to be optional.

The pre-gain is a regulation on the local device input volume, nothing else. This shall be done before anything else, including linking, EQ and output volume.

I really don't hope that it's implemented as an offset on the main volume control. That would be a great mistake.

@Wiimer The pre-gain values are stored in the device, not in the WHA.

I don't see a use case where you need it locally on the input device but not on linked devices.

The other option we have is the per source (input) volume. This works on the device that is used for output. For a linked device the volume will always be associated with the Network (WiFi/Ethernet) input until we get it split into the actual sources. This makes it even more important to be able to set pre-gains on the main device of the group.

I’m wouldn’t want my A+D example from above

That is why it doesn't make sense to have pre-gain on the network unless it's split into the actual sources (linking, media server, streaming services, radio, etc).

Each of these network sources may have different gains and would need there own pre-gain. I know that would not be easy!

I've been using pre-gain as a way to balance the final volume in different rooms, so that setting the volume in the WHA to, say, 50 or 35 or 70 results in the same volume in each room. I do mostly multiroom playing and this is an easy to keep the volumes consistent. This probably isn't consistent with the documented purpose, but I don't see an output gain or post-gain anywhere.

I also experimented with adjusting the volume controls on individual speakers, but ran into various problems.
