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. Refer to “The DC 24 User’s Guide,” on the Rane website, for an easy-to-understand guide of operation and applications.

Manual-1 DC 24 DYNAMIC CONTROLLER OPERATORS MANUAL DC 24 CONNECTION Placing the DC 24 within the chain of events in your system varies slightly depending on application. If you are assembling a sound reinforcement system, the DC 24 would typically be placed between the equalizer (you do use one, don’t you?) and the active crossover, or the power amplifier if passive crossovers (or the DC 24 crossover) are used. In recording applications, the DC 24 may be used in con- junction with insert loops on the mixing console or in series with the outputs en route to the recorder. Most consoles allow headphone monitoring of the processed signal if the device is connected to the inserts. A most useful feature. If the DC 24 is used on mixdown, it may be connected to the output of the mul- tichannel recorder or again on inserts of the mixdown console. Many recording situations require that the DC 24 be con- nected to the patch bay in the system so it may be easily moved from one signal location to another. This call should be made based upon the requirements of the application. Wiring of this and all components should follow the Sound System Interconnection RaneNote included in this manual. This note details standard wiring conventions which should be used to prevent noise and distortion. Also see the Chassis ground point on page Manual-3. QUICK START Shredded, this document makes excellent packing material. In its present form, it makes interesting and useful reading. If you run out of patience quickly, at least read this part to make sure you don’t exterminate everything in a two mile radius by doing some- thing wrong. In a nutshell, to use the DC 24 as a conventional dual channel compressor/limiter, ensure that the CROSSOVER ENGAGE switch on the rear is in its out position. Attach one or two channels of inputs and outputs to the respective connectors on the rear. With all RATIOS down, LIMITER THRESHOLD all the way up and the LEVEL controls in center-detent you have an expensive patch cord. Make sure the BYPASS switches are out and set the GATE and COMPRESSOR for the desired ratios and thresholds. Turning the LIMITER THRESHOLD down decreases the level at which limiting occurs. The GATES and COMPRESSORS may both be activated by the source material applied to Channel 1 if the DUAL/SLAVE switch is pressed in. This is a normal condition for true stereo program material. To use the DC 24 's crossover bandsplit mode, be sure the rear panel CROSSOVER ENGAGE switch is in. Connect the input to CH 1/CROSSOVER IN. With the rear panel OUTPUTS switch set to SEPARATE, split outputs are available at the CH 1/LOW OUT and CH 2/HIGH/COMBINE OUT jacks. With the OUTPUTS switch at COMBINE, use only the CH 2/HIGH/COM- BINE OUT jack for a mono sum of high and low channels. NEVER CONNECT ANYTHING EXCEPT AN RS 1 OR OTHER APPROVED RANE AC POWER SUPPLY TO THE THING THAT LOOKS LIKE A TELEPHONE JACK ON THE REAR OF THE DC 24. This is an AC input and requires some special attention if you do not have an operational power supply EXACTLY like the one that was originally packed with your unit.
