I just bought a 2.1 used. No manual (& none on their website) here is what I want to do: preamp #1 : Alembic F1-X into channel 1 preamp #2 : SWR IOD into channel 2 Set to stereo mode. 1 speaker : EA CXL-112 : My questions: a) any problems seen with prospective preamp hookups? b)can I hook the EA up to both ch. 1 & ch.2 speaker outs, by just hard-wiring each lead through both posts ? What I want to do : be able to select my preamp by simply switching between ch. 1 & 2 on the 2.1, using it one channel at a time. Thanks, Frank.
