We recommend that you take a moment and read this manual as it provides information that will help you in using your unit to its fullest potential. The RP282 provides smooth, natural compression and clear sonic quality and performance for the working musician, studio operator or anyone who needs a comp/limiter with warm, smooth analog sound. Each channel uses one ROLLS premium 7025 tube in a unique configuration to give superior signal control. The unit has both XLR and 1/4" inputs and outputs. Plus, it has a Side Chain input and output for each channel. The side chain provides direct access to the detector circuits. INSPECTION 1. Unpack and inspect the RP282 box and package. Your RP282 was carefully packed at the factory in a protective carton. Nonetheless, be sure to examine the unit and the carton for any signs of damage that may have occurred during shipping. If obvious physical damage is noticed, contact the carrier immediately to make a damage claim. We suggest saving the shipping carton and packing materials for safely transporting the unit in the future. 2. Please complete the Warranty Registration Card and return it to the factory. THE FOLLOWING SETTINGS ARE APPROXIMATE, THEY ARE LISTED AS SUGGESTIONS ONLY. VOCAL COMPRESSION The most effective way to connect your RP282 for vocal compression is by patching it into a channel insert of your mixing board. You will need an "insert" cable like the one shown. Connect the INPUT of the RP282 to the mixer's Send jack, and the OUTPUT to the mixer's Return. Set the level to the RP282 compressor by speaking or singing into the microphone at the same level used during performance. Set the Meter switch to Output, and adjust the gain control on your mixer so the RP282 meter moves to approximately 0. Press in the Active button to put the RP282 in compression mode. See the example diagram below for settings. OUTPUT LEVEL -20 THRESHOLD -10 4:1 RATIO 5:1 ATTACK RELEASE - OO dB +22 -20 dB +20 2:1 O :1 O .5 ms 100 .1 Sec 2 DRUM COMPRESSION The RP282 may be used to compress various drum parts for a smooth, tight drum sound as well as more control over a final mix. Connect your RP282 to the insert of your mixer and set the input level as directed above. Shown below is an example of a kick or snare drum compression setting. OUTPUT LEVEL -20 THRESHOLD -10 4:1 RATIO 5:1 ATTACK RELEASE - OO dB +22 -20 dB +20 2:1 O :1 O .5 ms 100 .1 Sec 2 4 1 FRONT PANEL DESCRIPTION REAR PANEL DESCRIPTION NOTE: Channel One descriptions are identical to Channel Two ACTIVE SWITCH: Engages and disengages the compression. OUTPUT LEVEL: Varies the overall signal level from the RP282. THRESHOLD: Sets the level at which the incoming signal must overcome in order for the RP282 to begin compressing. RATIO: Adjusts the signal to compression ratio. This sets the amount of increase in input signal required to raise the output signal 1 dB. ATTACK: Varies the amount of time taken for the RP282 to begin compressing after the Threshold level has been reached. RELEASE: Varies the amount of time taken for the RP282 to return to normal gain once the signal has dropped below the Threshold level. METER SWITCH: Switched the signal metering from indicating the output jack level, to indicating the amount of gain reduction. VU METER: Indicates either the output signal level, or the amount of gain reduction, depending on the position of the Meter Switch. NOTE: THE INPUT SIGNAL LEVEL MAY ALSO BE INDICATED BY PRESSING OUT THE ACTIVE SWITCH AND BYPASSING THE COMPRESSOR CIRCUITS. POWER SWITCH: Turns the RP282 main power on and off. NOTE: Channel One descriptions are identical to Channel Two. OUTPUTS: XLR balanced and 1/4" unbalanced connectors for connecting the RP282 to a mixer or other line level input. SIDE CHAIN INPUT: 1/4" unbalanced jack for receiving incoming signals to directly access the detector circuit of the compressor. SIDE CHAIN OUTPUT: 1/4' unbalanced jack for sending out the signal from the RP282. This jack may also be used as a pre-Output Level output. IMPORTANT: The Side Chain Inputs and Outputs are not effects loops, they break the signal path of the RP282 control circuitry. INPUTS: XLR balanced and 1/4" unbalanced connectors for connecting line level signals to the RP282.
