    Default My new PreAmp

    For test purposes I built a passive pre. It has 3 input now, but can accept 6. I installed a 100k pot, and a DPDT switch. I wired a set of 100k resistors across the switch for a safety limiting type device. It keeps my system under 100db in resistive mode, and lets it reach 126db+ in full signal mode;)



    Edit had to fix 1256db issue:o

    That orange thing in the background looks familiar.

    Could anything solid, liquid or gas stand up the force of 1256 db?

    Sounds very sweet. I am listening to Diana Krall right now. Earlier my buddy came in when listening to Allison Krauss, and said "I can hear her lips part". I can't wait to set these up in a a proper envirorment. 46 drivers in a 10x10 room is not ideal. One speaker is against the wall:(
