I'm in the process of installing an analog Rodgers Organ in my home and it too
requires speakers and I purchased five 100watt amps to drive speakers that I
don't yet own. However I am working with an engineer who also installed a
Rodgers organ in his home and what I will do is access his knowledge and see
what he would recomend as an answer to your question. He, like you demands
excellence and I know I can trust his judgement, so tomorrow I will email him
at work with your problem.

Greetings,
The Rodgers organ that was pulled out had three balanced line audio
outputs: great, swell, pedal. Each fed its own external power amplifier
and speakers. Those cables, amplifiers, and speakers are still installed
and work fine.
I am seeking a way to integrate the "new" 750 (with internal speakers we
would probably not use) so that it can feed these balanced line input
amplifiers in a similar manner. One way might be find a place in the
circuitry to insert high input impedance single-ended to low impedance
balanced transformers, one for each signal source, and couple to the
existing facility cables. Based on my past experience, just wiring into
the internal speaker wires (of which there are two sets) may not provide
the service and quality I'm seeking. Alternatively, there might be
something from Rodgers (like there was in the previous organ) to
conveniently provide the converted set of signals.

I have to ask how many amps are the amplifiers? The next thing I would
think is
that fi you spliced into the speaker wires and run them in series, you should
be able to have all speakers working. Unless I'm misunderstanding what it is
that you are trying to do.

Greetings,
I have been asked by a local church in Sunnyvale, CA that is replacing an
older
Rodgers organ with external house speakers and amplifiers with a 750 having
internal speakers and amplifier. I'm looking for information about doing the
internal -> external connections to the 600-ohm shielded twisted pair lines
to
the existing amplifiers. Naturally, we ended up with an owners manual but
have
not located any schematics so far.
