User manual RANE DC 24

[. . . ] With the OUTPUTS switch at COMBINE, use only the CH 2/HIGH/COMBINE 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. 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. [. . . ] (NOTE: Channel 2 OUTPUT LEVEL controls overall output in COMBINE mode. ) q SIGnal present LED: illuminates any time the input signal exceeds approximately -40 dBu. The OverLoad LED: illuminates any time the output exceeds a level equal to -4 dB below the clipping level. w DUAL / SLAVE mode switch: In the in (SLAVE) position, this switch causes both channels' Gate, Compressor and Limiters to act together, i. e. , they are "slaved. " All controls for both channels remain active, so independent settings are still possible; however, whenever a signal in one channel exceeds its settings, then both channels change by the same amount. e CROSSOVER FREQUENCY control: This rotary control selects the crossover frequency.

Choose either the XLR or the ¼" TRS jack, do not use both, they do not sum. 2 CHANNEL 1 / LOW OUTPUT connectors: deliver signal from channel 1's processing circuitry and represents the low-pass portion of the signal when the CROSSOVER ENGAGE switch 7 is in the in position. Both the XLR and the ¼" TRS jack may be used at the same time if desired. 3 CHANNEL 2 INPUT connectors: only deliver signal to channel 2's processor. It is disconnected when the CROSSOVER ENGAGE switch 7 is in its in position. Choose either the XLR or the ¼" TRS jack, do not use both, they do not sum. 4 CHANNEL 2 / HIGH / COMBINE OUTPUT connectors: make the signal from channel 2 available to the outside world and is the high-pass portion of the audio when the CROSSOVER ENGAGE switch 7 is in its in position. If the OUTPUTS switch 8 is in the COMBINE position, this output produces the sum of channels 1 & 2 and its overall level is controlled by CH 2 OUTPUT LEVEL. Both the XLR and the ¼" TRS jack may be used at the same time if desired. 5 SIDE CHAIN: Inserting a ¼" TRS plug into this jack breaks the input signal path to both the Compressor and Gate control circuit. Inserting an equalizer in this loop enables greater compression of boosted equalizer frequencies. 6 INPUT GAIN TRIM switches: In its +4 dBu position, the input gain of the respective channel is unity. In the -10 dBV position, the input gain is increased by 12 dB (although mathematically suspicious, it really is 12 dB, not 14 dB) to compensate for certain recording devices. This switch must be in the +4 dBu position for front panel calibration accuracy. 7 CROSSOVER ENGAGE switch: In its in position, this switch places the low pass portion of the audio signal on CH 1 /LOW OUT, and the high pass portion on CH 2 / HIGH / COMBINE OUT. 8 SEPARATE / COMBINE OUTPUT switch: In the COMBINE mode, the outputs of channel 1 and channel 2 are added together and delivered to the CH 2/HIGH/COMBINE OUT connector. [. . . ] Just be gentle at first and you should not encounter too much difficulty. If you become overwhelmed, go back to the PRE-FLIGHT CHECKLIST for initial control settings and start over. Use of BYPASS in the crossover mode is potentially destructive since these switches route full bandwidth audio to drivers designed only for a limited frequency range. 1 is still active -- do not engage the CH 1 BYPASS for any reason. ) Combine Mode.
