Balanced connections

Both have balanced XLR connections. A balanced cable carries the signal twice, on two conductors of opposite polarity. Interference picked up along the way lands on both equally and cancels when the two are recombined at the far end, so the longer the cable run and the noisier the surroundings, the more it is worth. Whether it also yields more power depends on how the amplifier is built inside - some are balanced end to end, others convert to single-ended internally and deliver the same either way.
