I suggest the Carver Lightstar Direct preamp as the only one I know that can do this trick. It has a passive (balanced) half and an active RCA half. You can use a passive input which will also appear at the active RCA outputs, with as much as 22 dB of gain available, if memory serves. It is a superb preamp, and there is one listed for sale at Audiogon.
Can a passive pre-amp feed a powered sub?
I am looking to find out if a passive pre-amp can drive a powered subwoofer like the Carver Sunfire Jr. The output from the sub's crossover will be used to feed an amplifier powering a pair of small satelitte speakers. Will a passive pre-amp work in this situation?
I don't need switching or tone controls or anything else, so it would be a shame to have to get a active lines stage to set this up. Thanks for the help.
