We have a Spider V user group on Facebook and one of our members told us about this mono clicking issue he's getting. Basically happens when you output to a cabinet mono, (one cable plugged in) and have amp modeling off, and set the mix to 70% on certain effects and you get this rhythmic clicking sound. Being that I also had an 240 HC, I decided to try and see if mine did it as well, and it does.
He has sent his amp back to the retailer multiple times, had all the circuitry replaced and what not. The final summation that it was a firmware issue that Line 6 had to fix.
Only problem is it is on the following effects:
all of the reverbs
except for the 3 spring reverbs and the Brite Room.
The Stereo Delay and Ping Pong Delay
The Sine Chorus, Line 6 Flanger, Rotary Drum+Horn, Auto Pan, Stereo Square Chorus, Stereo Expo Chorus, Hi-Talk, Sweeper
This only happens if you have amp modeling off and plugged in mono to the cabinet...

Can anyone else reproduce this issue?
