Controlling Levels
The DSP7000’s signal flow is diagrammed above. Bold boxes represent physical structures inside and out-
side the DSP7000, for example, the analog inputs. Dashed boxes represent parameters that impact signal
flow or gain structure. For example, “Levels/ main/ analog”
represents the
analog
parameter on the
main
menu page in the
LEVELS
area as shown to the right. Ovals represent points in the
signal flow that can be viewed with the level meters.
As you can see, the analog and digital inputs are summed or mixed before entering the processor. Further,
the AES/EBU and the S/P DIF inputs cannot be used at the same time. The rest is fairly straightforward
and will be discussed in detail in the following sections.
The Level Meters
Once you understand the Level Meters, you can adjust levels
along the signal path. There are two meters to the left of the
display, one for the left channel and one for the right channel. By
altering the
Source
parameter on the
meter
menu page in the
LEVELS
area, you can change the point in the signal path that the
meters measure. Your choices are:
analog in
measure the level at the analog inputs
after
the
gaintrim
(
LEVELS
/
inputs
/
gaintrim
).
digital in
measure the level at the digital inputs
before
the input cut (
LEVELS
/
inputs
/
digi-
tal
).
machine in
measure the level at the inputs to the DSP7000’s processor.
machine out
measure the level at the outputs to the DSP7000’s processor.
analog out
measure the level at the analog outputs
before
output cuts are applied.
digital out
measure the level at the digital outputs
after
output cuts are applied.
The parameter

determines how long the meters take
