The balanced input connectors on the F110, at least on the v2 version, are combo connectors that can accept either XLR’s or 1/4 inch TRS plugs. So as Rhyno stated a cable having XLR’s at both ends will work.
However, I’d suggest checking with BAT and asking them what the output impedance is of the pre-outs of your amp, **especially at 20 Hz.** The output impedance of at least some of their preamplifiers rises substantially in the bottom octave, reaching several thousand ohms at 20 Hz, due to the specific values of the output coupling capacitors used in those designs (the impedance of a capacitor rises as frequency decreases). If the pre-outs of your amp are similar in that respect, given that the balanced inputs of the F110v2 have an input impedance of only 10K perceptible rolloff of the deep bass content of the signals received by the subs would result.
Good luck. Regards,
