Laney Lfr-112 Frfr and quad cortex volume wheel

Hello guys

need some help or advice about something that’s haunting me.
I have a quad cortex and a Laney Lfr-112 Frfr.
what’s the most correct way to handle volume ?
how do you set up the volume wheel on quad cortex ? at 100% ?
at the same time how do you set up volume wheel on the laney ? at half ?
now I 'm currently putting the volume on the laney at 50% and control(attenuate) the volume with the big wheel on the cortex , 90% of the time I am at 50% there too
at 100% on the cortex wheel would be deafening
what’s the most correct way to proceed here ?
thanks for your help

I can’t help on the Laney FRFR but NDSP recommends to keep the main volume at 100% as it acts as an attenuator.
