Some X32 users reported a sound change when linking 2 (already) hard panned channels. So I thought it would be good to measure what’s happening.
Interface: Saffire Pro 24
Reference: Interface Out –> Interface In 3
Measure: Interface Out –> X32 Aux In 1 (routed to CH 01 and CH 02)
X32 Main out (Out 15, 16) -> Interface In 1, 2
Aux In 1 is routed to CH 01 and CH 02. CH 01 is hard panned to the left and CH 02 hard panned to the right
Every processing is disabled on CH 01, 02 and MainLR (No gate, no eq, no inserts, …)
Note: Goal of the measurement is to detect a relative difference, not a absolute value!
This measurement shows the frequency response of the complete X32 signal path (In+Out)
As you can see the two curves (green and blue) match eachother. This shows us that the left and right channel are exactly the same.
So let’s save the curve and link the two channels.
As you can see the blue and green curve is still the same. The only difference is a drop in comparison to the pink curve (saved measurement from above).
I did not change any volumes, trims or gains while running the measurement.
This shows us that the only difference between a linked and unlinked channel is a volume drop.
