Output: Controls output attenuation level. This exact recovery time is calibrated for Peak limiting operation and will result in slightly longer Release times than indicated when Function control is adjusted towards RMS compression. Release: Adjusts the release time of compression from. RMS/Peak LEDs: LED indicators provide visualization for which type of limiting is occuring. ![]() The “Function” has the effect of raising and lowering threshold as well as the audible feel of an attack control. All other parts can be purchased through Mouser or distributors listed on the BOM.įunction: This variable control adjusts between Peak limiting and RMS compression, providing for either extreme or a blend of both. The GB-1 additionally provides the more standard Input, Output, and Release controls as well as the 7 segment Gain Reduction LED meter and Peak/RMS indicator LEDS.ĥ00 series GB-1 rev-D PCB set, Faceplate, Meter board hardware, hookup wire, 24V relays (2), FETs measured for Vgsoff for Gain Reduction and GR Meter control (Q12 and Q29), DPDT toggle switches (2). While blending between Peak and RMS detection circuitry the control essentially acts to raise and lower the compression threshold and ratio and thus discernibly altering the attack time. ![]() ![]() The circuit remains true to the clever variable adjustment between Peak and RMS limiting via a “Function” knob. The DEAD GB-1 variable Peak/RMS Compressor/Limiter is a faithful recreation of a 1970’s era FET limiter circuit adapted for the modern 500 series format.
