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.
