Lisson Grove R-124 Tube Compressor/Limiter #063 (Used)
After nearly 50 years in clandestine use, Lisson Grove makes this remarkable design available to all. The R-124 takes this secret weapon of a bygone era and updates it with additional functionality and modern conveniences. These updates make the R-124 ready for modern recording environments and applications while preserving the rich tube sound of the past. Each unit is hand crafted in the USA using the highest quality components available to ensure many years of faithful service.
The Input control sets the pre-compression level
The Output control attenuates the post compression output level
The Threshold control sets the compression sensitivity to incoming transients
The Attack control sets the speed at which the compression reacts to the source material. The attack control potentiometer is also a push-pull switch. Pulling the switch bypasses the compression circuit, without bypassing the other stages. Allowing the user to employ the rich tube sound of the R-124 without compressing the signal.
The Release control determines the speed at which the compression returns to unity after the input signal falls below the set Threshold. The Release control also features Infinity settings between each Release setting. The Infinity settings exhibit an extremely long release time. There are a variety of uses for this feature, such as using it to prime the amount of compression before a take. This is done by placing the Release control in an Infinity position (one click up or down from the desired setting), having the performer play or sing a note before recording, then switching to the desired Release setting when the performance begins. Another use of Infinity would be to prevent an increase in gain during silent passages, to maintain the desired level and compression amount through the entire composition. The R-124 also features a 1/4" jack on the rear panel, to allow hands-free use of the Infinity setting via a foot-switch.
The Balance control provides an easy way to even out the two sides of the gain reduction tube, thus minimizing distortion and feed-through thumps. Simply press the front panel push-button and a pulsing sound will be heard. Adjust the front panel trim potentiometer until the pulsing sound reaches the lowest possible level. The Balance control provides a practical means of gain reduction calibration, minimizing interruption while in session.
The O/P Load control adjusts the R-124s output impedance from 200 ohms in the controls leftmost position to 600 ohms in the rightmost position. The change in impedance will result in a change in the units overall tonality, with a darker tone at 200 ohms and a slightly livelier tone at 600 ohms. This design approach allows the user to choose the tone they desire, without introducing any incongruous circuitry.
The R-124 is equipped with a 1/4" TRS jack to link units for stereo use.
An analog Hoyt meter monitors gain reduction in dB.
