Biamp Desono ENT-750T - Autoformer for ENT-FR or ENT-LF (Black)The ENT 750 W autoformer is a step down auto transformer for use with the ENT FR or ENT LF in constant voltage distribution systems. Designated the ENT 750T, it can be used to minimize the I2R losses of long cable runs by converting the distributed high voltage, low current signal to a lower voltage, higher current signal that can effectively drive the ENT FR LF column loudspeakers. The ENT 750T is available in either black (ENT 750T) or white (ENT
