Designators on blocking ouput circuitry do not match between pcb and schematics
Because the output blocking circuit is repeated 18 times, the schematics
only show this once on page 12, and relies on multi-channel capability
of Altium to describe this repetition on page 11.
However, this has lead to the wrong annotation or designators on the components of the circuit, as shown on the screen grab below.
Furthermore this means that it is not straight forward to try to match one output channel to its blocking output circuit block.
The schematics should therefore be modified to make multi-channel
annotation more intuitive, for example by using a number for each
component of the output circuit, and a letter from A to F to designate
the corresponding channel.
The silkscree should also reflect that, and maybe add some marking to show the different channel numbers.
