CV Inputs On the back of the RV7000 Mk II you find three CV inputs. These are: | Parameter | Description Decay Controls the reverb decay or echo/delay feedback via CV. HF Damp Controls the HF Damp parameter on the main panel. Gate Trig Used for triggering the Gate section with a gate signal. The length of the gate signal determines the length of the gated reverb. Using the CV inputs to modulate the RV7000 Mk II in Convolution mode is not recommended.
