 Jacob wanted to use four McCune JM3 loudspeakers but the rental cost was nixed by the producer, and Altec 9846 self-powered cabinets were used instead, powered in this case by distant amplifiers so that the sound crew could more easily correct a potential amplifier problem.Two 16-channel stereo mixers were specified by Jacob, custom made by Louis Stevenson of Houston.The orchestra was mixed on one of them, with the results patched into the second Stevenson as a stereo stem, for blending with the vocal and area mics.
