Input Channel Insert Connections
All insert sends and returns are balanced, low-impedance, line-level signals routed via
¼" tip-ring-sleeve jacks on the rear panel.
The insert send is post-EQ on channels 1 & 2.
The insert send is post-500 slot on channels 3 & 4. In addition to the insert send and
return, the signal path on channels 3 & 4 can be accessed pre-500 slot via the
PREAMP OUTPUT and 500 SLOT INPUT jacks on the rear panel.
* The PREAMP OUTPUT and 500 SLOT INPUT jacks work as a "half-normalled" pair and
the channel signal flows through these jacks. If a plug is inserted into the 500 SLOT
INPUT jack, that signal replaces the signal from the PREAMP OUTPUT jack. The signal
from the onboard preamp is broken and does not continue in the channel flow path.
