On the DME, set up the required processing to be carried out on the key
fill signal (PROCV) and key source signal (PROCK).
On the DME, make the settings so that the PROCK signal level is not
affected by a DME external key signal (so that the through output is
obtained from the keyer for the external key).
To do this, in the DME IN/OUT menu, set the front and back key modes
to “External”, and set both clip and gain for the external key signal to
0.00.
For details of the operations on the DME, refer to the BZDM-7720/3720
User’s Guide.

To carry out clean key processing on the return signals (DMEV and
DMEK) from the DME, press F9 (CLEAN KEY), turning it on.

Press F10 (KEY ADJUST) to select the method of adjustment of the
DME return signals. Pressing F10 toggles between PRESET and
VARIABLE.
PRESET: the clip level and gain are automatically adjusted to preset
values suitable for using the output key signal from the DIGITAL
OUTPUTS connectors on the DME on the switcher.
VARIABLE: selecting this allows manual adjustment of the clip level
and gain.
Notes
• For each M/E bank or the DSK block, the processed key uses the
following of the two channels selected by the DME IF item in a setup
menu (see page 14-40): DME 1 for keyer 1 and DME 2 for keyer 2.
• For each M/E bank or the DSK block, if a DME wipe and processed
key use the same DME, the one which was selected first takes
precedence.
