The upper section consists of a half of a A-144 ring modulator and has inputs for the signals X and Y. The X*Y output emits the multiplied / ring modulated signal.
The bottom section is a sample & hold followed by a slew limiter.
It has an input for the sample signal and a trigger input. A switch select mode of operation as the module can work as a sample & hold or as a track & hold.
When in T&H mode no trigger is applied this section can be used as an individual slew limiter.
