APPLICATION

Electrical isolation where the source is a low impedance. Creates a floating output from an unbalanced or balanced source which can be loaded balanced or unbalanced. May be used for balanced to unbalanced conversion and vice versa. An ideal transformer for balancing the output of a pre-amplifier to enable it to drive a balanced line. The pre amp should have an output impedance up to 600 Ohms. The load can be any value equal or greater than 600 Ohms. See application circuit below. Replaces type 5069.

FEATURES

High impedance presents minimal load to a source up to 600 Ohms even at 15 Hz. Mumetal core for minimal harmonic distortion. Mumetal can for magnetic shielding. Secondary centre tap for phase splitting, Phanton powering etc. Various package options.
