I am thinking about purchasing the CX311 crossover with the SLA4 amplifier to bi-amp my 2-way speakers. Do I need a 4-channel pre-amplifier to make this work properly....?

No, you do not need a 4-channel pre-amplifier to use the ART CX311 crossover with the SLA4 amplifier for bi-amping 2-way speakers. The CX311 splits a stereo signal into high and low frequency outputs for each channel, allowing you to send separate signals to different amplifier channels. You can connect the CX311's LOW and HIGH outputs for each stereo channel directly to the corresponding channels of the SLA4 amplifier.
