Hello, One of my Mackie Mr8s has started playing up. The problem is when I input balanced signals into them (it happens to both the TRS and XLR inputs) they do not have equal volumes. One of the monitors is a lot quieter than the other, Im sure the problem is caused by the speaker because 1. I have tried different cables 2. Ive tried different sources of sound where the signal is coming from and importantly 3. When I connect them both via the unbalanced input (RCA) they have the same volume and sound normal duh Whats going on? I find it strange that it only happens to the balanced inputs... Hopefully someone on here knows, I cannot find anything on the internet! Thanks.
