Chapter 4: Mic and Line Preamps
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 input) 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.
It is also possible to route these preamps to des-
tinations other than Pro Tools.
Microphone and Line Preamps
All 16 input channels in Control|24 are switch-
able between microphone and line level opera-
tion.
Channels 1 and 2 have DI (Direct Inject) inputs
that serve the same function as a direct box in
accommodating instrument-level signals such
as from an electric guitar or bass.
Channels 3–16 can be switched between stan-
dard 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.
