channel 6, then release INPUT D. To route INPUT D to both channels 1 and 6, press and hold INPUT D then press SELECT for channels 1 and 6, then release INPUT D. The routing is verified by LEDs when you make the selection.
Whenever you route an input to a channel, the 788 will automatically disengage both the input and the channel from any previous assignment so that you don't have to worry about double routings.
If you want to check where things are routed, press and hold the input button; its LED will flash with the LED of the channel it is assigned to. (If none of the other LEDs flash, then it's not routed anywhere, yet.) The reverse can also be done, you can press SELECT for any of the channels, and it will flash with the input that is assigned to it.
Inputs can also be routed to the input submixer, which is discussed later in this section on p10. Routing an input to the input submixer is done by holding down the SUB MIX button and pressing the buttons for each INPUT you wish to route.
THE CHANNEL STRIP
The 788's main mixer provides extensive processing power and routing flexibility. Once the signal is routed to the main channel, the signal flows through the following steps:

of the 788, press the EQ button right in the middle of the 788's
control surface, then press SELECT for the channel you wish to view. The screen to the right should appear.
The 788's three band EQ is comprised of sweepable high and low shelf bands, plus a parametric mid band. An ON/OFF switch allows A/B
comparisons between the enhanced signal and the original. Finally, a PAD/GAIN control allows the signal to be padded down to prevent the channel from overloading from high boost EQ curves, or to increase signal strength when large frequency bands areas are dug out of the signal's power.

Examples - Perhaps 80Hz boost will offer pillowy sound to a bass, while a 200Hz cut will take out a muddy tone.
