6.10 Open/Shut
LEDs
If the gate is not passing program, the shut light is illuminated. If it is passing
program, the open light is illuminated.
These lights fade from one to another during the attack and release times,
their relative intensity giving a visual indication of the dynamic response of
the gating action.
One thing to remember is that during the attack and release phases, as stated
earlier, the DPR 944 uses a logarithmic control law to give a smooth fade to
the sound. When this is applied to the lights, especially for long release times,
it may appear as though nothing happens for a while. What is in reality
happening is that the sound and lights are fading, but the lights are initially
fading too slowly to be noticable.
6.11 Key insert
connector
This connector carries both the ‘key send’ and ‘key return’ signals. The key
send is a buffered version of the signal applied to the
main input. It may be
used as such, or can be connected to the input of external equipment for
further processing.
The key return is the input to the DPR 944s key side chain. It may be used as
the return input from equipment being driven from the DPR 944s key send
connector, of if desired may be driven from another unrelated signal.
Refer to section 5.3 for the wiring details of this connector.
