You can pull them out, no problem. That is what I did.
Pass Labs 30.5 Amp owners help
I'm attempting to use banana speaker connectors with my 30.5 amp. The terminal lugs seemed to be capped rendering the ability to use banana plugs not possible. Are these caps removeable and if so, how does one remove the caps. It seems odd that a manufacturer would use speaker terminals that do not allow use of banana plugs. Anyone with an answer to my dilemma, please tell.
