Thank you @JimHowell1970 and @Lugia for clarifying mults and attenuators in setups. I will keep the buffered mult and use that with other modules for my second rack as well as the passive mult. I do have attenuators in my Intellijel Quad VCA and can get one for the second new rack. Since I have 2hp free in my first rack, would you recommend the 2hp trim attenuator or another module and if so, what one?
