The internal rectifier senses the long term average signal level and controls the filter response by setting the control current of the filter. The rectifier sensitivity, with respect to the input signal, can be increased by placing the internal preamplifier (A) before the filter section of the GR581. The preamplifier has an internal 265 k feedback resistor from its input to output, to facilitate in setting the gain. |
