NOTE: Since the M/E processor and the PGM/PST/DSK
processor share the Effects Loop return path, you can
enable only one Effects Loop at a time. However, if you
have four Aux outputs installed, you can use them to feed
two different DVEs to create different Effects Loops, as
long as they are not used simultaneously. Alternatively, if
the internal DVE option is installed, you can use it for one
Effects Loop and an external DVE for another Effects Loop,
again provided that they are not attempted
simultaneously.
Effects Loop Re-Entry Timing
You must reference an external DVE, or any device fed by an Aux output
to perform effects looping, to the Aux Ref output associated with those
Aux outputs. The issue now is how the 8150 deals with the DVE re-entry
after it has been delayed by the 18 or 34 lines of processing time, since
the 8150 input timing window range is only one half line advanced to
two lines delayed from reference.
