Unpatching - Calrec SUMMA User Manual

Unpatching

Under normal circumstances, when I/O box ports are unpatched, their input settings (Mic Gain, SRC, 48 V) are reset to
their default values. However, when using HPBs, it is possible to un-patch a port at two points in the signal chain, as
shown below. If the port is first un-patched at point 2, the I/O box port's input settings will be retained, even when the
port is also unpatched at point 1.
