Auto adjust pre-gain or volume limit when using RC

[DamagedGoods]

How come there’s no automatic gain reduction when RC boosts gain on certain frequencies? The result right now can be severe clipping.

When I run RC on my Ultra, it applies a total gain boost of 7-8 dB in a mid bass frequency range. When this is not compensated by lowering gain all over the frequency spectrum, it results in really bad clipping. If I run a chirp and sine sweep, I hear it very clearly. Same if I play a track with lots of mid bass.

I solve this by manually setting volume limit, in my case 85%, since I measured clipping at 90% and want some headroom.

I assume most people using RC won’t even understand they have clipping, let alone how to fix it. Auto gain adjustment would make sense to me, at least as an option.

I’d say it’s been well discussed in the forum and this link from a year ago has often been quoted when the issue is raised

However, I do agree it would be good if the WiiM Home app worked this out automatically for you when peq/rc is applied.

The problem has been known since the existence of EQ mode mid 2022..and aggravated by the PEQ mode and the behavior according to the Q factor of the LS and HS modes .... even in negative correction...
and therefore concerns of course eq..peq..and rc mode
in l/r mode the level of the channel requiring the greatest level reduction should be considered...

but hey...we have VU meters and clocks with the ultra... zuuuuperrrr
