DC 24
DYNAMIC CONTROLLER
Data Sheet-1
General Description
The Rane Model DC 24 Dynamic Controller is a two chan-
nel Compressor, Limiter, Expander Gate system with very un-
usual attributes. The DC 24 offers unprecedented control of its
operating parameters as well as a built-in 24 dB/octave Linkwitz-
Riley Crossover which gives it very impressive capabilities.
Total freedom from control interaction highlight the DC 24
as well as the availability of separate Compressor and Limiter
controls. The Compressor offers control over both Ratio and
Threshold, while the Limiter allows setting a separate Threshold.
In doing this, the DC 24 allows the operator to create a smooth
transition between subtle compression over a wide dynamic
range and peak-stop limiting at the sound system’s highest allow-
able level. If that’s not enough, the DC 24 also offers indepen-
dent Expander/Gate Ratio and Threshold controls. This third
level of signal manipulation makes the DC 24 a most useful and
revolutionary device.
Attack and release times are automatic and program depen-
dent. This simplifies use of the DC 24, as these subtle controls
can confuse most users. History has proven that experienced
compressor users rarely miss these controls after using a DC 24.
The internal Crossover allows the DC 24 to operate as a
two-way speaker dividing network along with all of the dy-
namic characteristics of a fully featured Compressor Limiter. In
addition to this application, the DC 24 supplies the necessary
circuitry to allow the unit to divide a single channel of audio
information in two separate frequency ranges and to then re-
combine the program material into one Channel. Using the DC
24 in this way eliminates the pumping and breathing associated
with compression and limiting when only one Channel is used to
cover the entire audio spectrum.
