Produces control voltages proportional to the amplitudes of applied signals. Unit has a wide dynamic range and can be used in conjunction with a Model 292 Lopass Gate to accurately transfer envelopes from one signal to another. Decay time is adjustable from .1 to 5 seconds.
In the direct coupled mode, pulse outputs are activated when corresponding control voltages exceed 6 volts. Transient coupling permits the detection of attack transients in the presence of background noise and over a considerable range of amplitudes.
[Early models produce pulses above 7.5 volts and featured switchable linear/exponential detector slope in lieu of the direct/transient coupling feature]
