Description
Calibrations can be absolute or relative. Absolute calibrations are not biased by the calibration reference and would, therefore, be more reproducible. However, absolute calibrations can be more complex to determine. The bias in relative calibrations would be consistent if all the devices in the system are calibrated against the same calibration reference. Calibrations may also be performed relative to other devices without reference to an absolute standard. Relative calibrations are generally simpler to perform than absolute calibrations.

Passive summing, OTB calibration

Ok, so I just moved OTB by building my own 8 channel passive summing mixer (DIY Recording Endless Summer) and I would like some input on calibration. Here is my setup:

Logic Pro with a MOTU 828mk3 Hybrid

All 8 analog outputs are being used as 4 pairs of stereo stems (1/2, 3/4, 5/6, 7/8)

Each stem inputs to the 8 channel passive summing mixer
