Boss RCL-10 Compressor Limiter

The Boss RCL-10 Compressor/Limiter is a dynamics processor integrating the functions of a compressor, limiter, expander and noise gate into its compact dimensions. A high-performance VCA makes possible a very high S/N ratio with low distortion to ensure your sound stays clean without distortion. The compressor will even out the levels of sounds with wide dynamic ranges, while the limiter will just compress input peaks, thus reducing distortion.

The expander function acts to expand or increase dynamic range, for those times when sound with great dynamics is required. The independent ATTACK TIME and RELEASE TIME controls allow the user to make very fine adjustments to achieve the exact effect he seeks. The noise gate function keeps noise down when nothing is being played. There’s also a key-in jack for producing a gate echo effect when the unit is combined with a reverb.

Controls

• THRESHOLD: For selecting the level of the signa/ at which compression/limiting will be activated.
• RATIO: This adjusts the ratio of compression. Setting this control determines whether the RCL-IO will function as a compressor, limiter or expander.
• ATTACK: For adjusting the amount of time before compression/expansion/limiting comes into play.
• RELEASE: For setting the time till the desired point of release.
  NOISE GATE FUNCTIONS:
• THRESHOLD: For selecting a point beyond which the input signal will noise-gated.
• DECAY: For adjusting the time it takes for the input signal to decay and fade out.
• OUTPUT LEVEL: This will adjust the level of the compressed/limited signal being output.

Because the Boss RCL-10 incorporates the 4 different functions of compressor, limiter, expander and noise gate, it is important that the user fully understands each function and effectively uses each function.

In the above, the relationship between the threshold level and ratio is shown when employing the Boss RCL-10 as a compressor/limiter/expander. As shown here, just (he signal which exceeds the threshold level is compressed or expanded, depending on your particular requirement. It is important to note that compressors and expanders generally shape the sound in a total manner, so care should be taken to set the THRESHOLD and RATIO controls at low settings. But when the Boss RCL-10is used as a limiter to squash input peaks, set the THRESHOLD and RATIO controls to higher levels.
