Messing around with my Mackie I noticed that on page 4 of the schematic it shows J16 for the HF output to the driver/tweeter...... On the schematic, the + and - are actually reversed on what is at the terminal. So, from the schematic, my tweeter negative is being hooked up to the positive and vice versa........

R262 going to + terminal..etc...

My other Mackie is the same........

Anything to worry about or is my tweeter just out of phase??? Or is it actually in phase and the schem is a typo???

What am I actually seeing????

Thanks!

Or somewhere in the myriad of filters and op-amps a signal inversion has occurred.
I think HF phase reversal is the least of your worries with those speakers.
