Axiom Home Page Forums General Discussion Home Theater No trim button on my EP500 ?

Hi Guys,

Just got my new EP500 sub today. There is no trim button on the amp, just a " subsonic filter" with an ON or OFF position. The instructions that came with the sub contradict themselves, first the picture of the amp shows no Trim or Bypass setting, but Step 7 in the instructions refer to Trim: Flat, Load and Remote and Step 3 refers to "bypass" .. both are not present on the amp ? ?

New amp ? or old amp ? and no explanation of "subsonic filter" in the instructions..I'm guessing it's a room boundary switch ? Don't know..

Also, since the EP500 has been out since 2005.. has there been any firmware updates via it's USB port ?
