Introduction and Overview
2. Amplifier Overview
UXA4401 amplifiers are half rack width, 1U format power
amplifiers that can drive both conventional low impedance (Lo-Z,
4Ω to 16Ω) loudspeakers and high impedance (Hi-Z, 70V/100V)
transformer coupled loudspeakers. They provide four analog
inputs, one stereo S/PDIF digital input, and either two or four
outputs (Lo-Z mode), or one or two outputs (Hi-Z mode). UXA4401
amplifiers also incorporate automatic power sharing technology
that enables power to be shared proportionately as required
between pairs of outputs in Lo-Z mode. UXA4401 amplifier model
output channel counts and power outputs are as follows:
