AC Power Draw and Thermal Dissipation
This datasheet provides detailed information about the amount of power
and current drawn from the AC mains by the I-T4000 amplifi er, and the
amount of heat produced under various conditions. The measurements
presented here are intended to provide a realistic and reliable depiction
of the amplifi er.
I-Tech 4000 AC Current Draw and Thermal Dissipation:
Pink noise 12dB crest factor, bandwidth limited 22Hz to 22kHz.
Typical line impedance used.
Data based on both channels driven.
