Adding Pre-Out / Main-in to an integrated amplifier. Second try.
Trying to add a Main-in/Pre-out to a Sony amplifier:
(There were useful replies, in an earlier thread, from K. Robinson, Jerry G. and NSM about this topic) The amplifier model: Sony TA-F590ES, with motorized volume control. The amplifier has an "adaptor loop" with bridged IN & OUT cinch(RCA) connectors before the volume control. The aim is to insert a 2-way active crossover, and resend the high-range output to the Sony. The adaptor loop won't do since it come before the volume control. One point worth mentioning: the "Pre-out" and "Main-in" under discussion need not have "universal" characteristics, since they will *only* be dealing with an active crossover (and perhaps an equalizer.) It has been suggested by NSM: "post a circuit diagram and several of us could tell you where to add them" Here are the block ad circuit diagrams: http://nom.de.plume.free.fr/temp_files/ The diagrams are for the TA-F590ES and a variant, the TA-F690ES. The latter has a Pre-out, but no Main-in. We are discussing here the TA-F590ES (Please consider that the content of the files may be copyrighted.) Thank you, in advance, for your contributions. |
