Summing Input Controls
3.1 Input Routing
Summing inputs accept balanced, low-impedance, line-level signals from the
SUMMING INPUTS 1-8 and SUMMING INPUTS 9-16 DB-25 connectors on the rear
panel.
This line input is the primary summing channel input. Other than the insert return, it’s
the only input available.
3.1.1 Insert
A balanced insert with switch is provided on each summing input.
The insert send is fed pre-fader immediately after the line input and is always active.
The insert return is located before the fader bypass (0dB) and is routed to the signal
path only when the INS switch is engaged
INS (insert): Routes the insert return to the signal path
