The FL2 was designed as a replacement for the FL1 and was styled in the aluminium wrap-around case. It could be configured as dual BP filters or independantly tuned HP and LF filters. For some reason the auto-notch of the FL1 was omitted, this could be purchased as a retro-fit board FL2/A. This was latterly available as the FL3 with the auto-notch fitted.
