USER MANUAL
iA480X Power amplifier
AMPLIFIERS OUTPUTBALANCED PHOENIX AND STEREO RCA INPUT
Connect audio signal to electronically balanced phoenix connector or to stereo
RCA. Please note that the iA480X needs at least 0 dBu to achieve maximum
power.
INPUT GAIN CONTROL
This control allows you to precisely adjust the input level of the signal arriving
at the rear-panel input connectors. At their fully counterclockwise position, the
signal is attenuated by -80 dB. At their fully clockwise position, the signal is no
attenuated. When 0dBu of signal arrives at the input and the input level controls
are set to their fully clockwise position (0dBu), the Amplifier delivers full power.
