Chapter 4: Mic Preamps and Control 24
Outputs
Control 24 is equipped with 16 preamps for mi-
crophone or line-level signals. The first two in-
put channels are also equipped with instru-
ment-level DI (direct inject) inputs to
accommodate high impedance signals such as
those from electric guitars and basses.
You may want to use these preamps as a “front
end” to your Pro Tools audio interface, since
they will accept virtually any standard audio in-
put signal. By providing hands-on access to an-
alog signals from the Control 24 surface before
they reach the A/D converters of your Pro Tools
audio interface, these preamps give you a level
of control that you don’t have with Pro Tools
alone.
It is also possible to route these preamps to non-
Pro Tools destinations as well. The preamp out-
puts can feed most professional audio gear;
these preamps can therefore be used as stand-
alone units regardless of whether they are con-
nected to Pro Tools.
Microphone and Line Preamps
All 16 input channels in Control 24 are switch-
able between microphone and line level opera-
tion. Channels 3–16 can also be switched be-
tween standard professional line levels (+4) and
semi-pro or consumer line levels (–10).
Phantom power is activated in banks of eight
mic preamps at a time, and is indicated by ded-
icated red LEDs above each of the two banks.
In addition, channels 1 and 2 also have DI (Di-
rect Inject) inputs that serve the same function
as a direct box.
