Ive just bought a 2nd / 3rd maybe even 4th hand A&R active set up, consisting of A&R A60 integrated and SA60 power amp and ARC (crossover-less) speakers. I have gathered that the A60 has a its aux input modified so it works as a pre out, it then outputs to the power amp, which has crossovers in it. the signal is split, (into bass and treble), and the left channel is sent back to the A60. This meas the A60 does one speaker, the SA60 the other. Does anyone know if its possible to remove the crossovers from the power amp, whilst keeping the pre out on the A60 (as it doesnt normally have one), in order to use these amps with modern speakers, in a conventional bi-amp system
