flax Posted August 31, 2022 Share Posted August 31, 2022 (edited) I read that the Reference Premiere model RP-8060FA II are equipped with dual binding posts... is it then possible to bypass the passive crossover and biamp them with an external digital crossover without modifying them internally? Thanks!! Edited August 31, 2022 by flax 2 Quote Link to comment Share on other sites More sharing options...
moray james Posted August 31, 2022 Share Posted August 31, 2022 The double set of binding posts are actually so you can split the two crossover sections and drive them independently, tweeter and woofer and then you can run them with a stereo amp. Two identical stereo block amplifiers are what you want to use so they match in both sonics and in gain. Run one stereo amp per speaker channel. So the first stereo amp would be connected with one channel to the woofer section and the other channel to the tweeter section both channels being fed from your preamp out via a splitter to the amplifiers left and right inputs. Same arrangement for the other channel. Hope this helps. 1 Quote Link to comment Share on other sites More sharing options...

Hope this helps. just so we are all on the same page the preamp output for the right channel is sent to the stereo amplifier which will drive the right speaker. That right channel signal will be split using a simple one input to two output splitter which is then connected to both of the inputs of the right channel stereo amplifier. In this way you will feed both of the two channels of the stereo amplifier driving the right speaker with the exact same right channel signal. Running identical stereo amplifiers insures that both of the drivers in each speaker are in phase and are exactly level matched. Quote Link to comment Share on other sites More sharing options...

NO; the speaker terminals are connected to the internal crossover. To run it with a DSP you have to connect the DSP outputs directly to the individual woofers/tweeters/etc. Quote Link to comment Share on other sites More sharing options...
