Effects Send – Looping Mode
Looping mode takes the output of an M/E Keyer, sends it to an
external DPM, then returns the output of the DPM to the
Mix/Wipe circuit of the same M/E in the switcher. This provides
the effect of inserting a DPM right into the M/E, between the
Keyer and the Mix/Wipe system. To select Effects Send looping
mode, first press the AUX BUS button on the main menu panel,
then press the LOG AUX SELECT soft button to select the Aux Bus
to be looped. With the EFF LOOP MODE button, select EXT LOOP.
5. With one of the BUS DELEGATE buttons, select the (physical)
AUX BUS (1-4)
that you want to use. With the switcher set up
as described previously for looping, the DPM output will
automatically be routed to the Mix/Wipe system of the M/E
whose Keyer output you sent to the DPM.
6. Select the Keyer output to be sent to the DPM by pressing one
of the AUX 1-4 EFFECTS SEND ONLY buttons on the
PVW/AUX row of buttons (M/E 1B through M/E 3 KEY 2).
NOTE:
