N2 - We perform the classical gravity calculations of the fixed scalar absorption cross sections by [Formula presented]=5 black holes with three charges and by [Formula presented] black holes with four charges. We obtain analytic results for the cases where the energy and the left- and right-moving temperatures are sufficiently low but have arbitrary ratios. In [Formula presented] the greybody factor is in perfect agreement with the recent calculation performed in the context of the effective string model for black holes. In [Formula presented] the formula for the greybody factor in terms of the energy and the temperatures differs from that in [Formula presented] only by the overall normalization. This suggests that the fixed scalar coupling to the effective string in [Formula presented] is identical to that in [Formula presented].
