Quiescent signal from VCA and Envelope outputs on Cascade

Our Modules Cascade
1

Someone asked me if the VCA goes completely off and the envelope output goes to zero when the Offset pot is all the way down. I measured the following, using a Fluke multimeter on the millivolt setting.

Cascade #1
VCA – 6 mV AC, Envelope – 22 mV DC

Cascade #2
VCA – 9 mV AC, Envelope – 6 mV DC

These are quite small, and I’ve never noticed the signal bleed. Is this normal? Is there a way to trim the offset?

Thanks,
