-
what is outboard equipment
anything not connected to the console
-
Name the 5 domains of outboard gear?
Tonal, Time, Dynamic, Frequency and Spatial
-
What is a parameter
something that can be adjusted or controlled
-
outboard gear can be broken down into to 2 groups what are they?
Effects, Signal processors
-
What do you call the place all inputs and outputs are connected?
the patch bay
-
What are the two main rules?
- Never connect an output to an output
- Any line level output can be connected to any line level input, other than its own, if it is upstream in signal flow.
-
what is a patch point
Any individual jack that allows us to access our signal
-
what is an insert point?
Any pair of jacks that allows us to add an additional component to signal flow.
-
what domain has devices that affect harmonic content
Tonal domain
-
What do we call passive tone control
filters
-
what are the parameters of filters
cutoff frequency and slope
-
what type of filters reduces lows
High pass filter
-
What kind of filter reduces highs?
low pass filter
-
what does a band pass filter do?
reduce lows and highs.
-
what do we call a very narrow band pass filter
a notch filter
-
what is cutoff frequency?
Any frequency that is reduced −3dB from normal.
-
How is slope measured?
dB’s per octaves
-
What is a series of notch filters called?
a comb filter
-
what do we call it when we automatically sweep the center frequencies up & down?
sweeping comb filter
-
What are the parameters of that device?
speed and depth
-
what do we call an active tone control
A tone control with an amp (an EQ for example)
-
