Bogen WMT1AS Line Impedance Matching TransformerThe WMT1AS has all the features and functions of the WMT1A, but can also adapt speaker level signals (25V 70V systems) to a level suitable for the AUX input of an amplifier. The Bogen WMT1A transformer is designed especially for impedance matching inputs from, or outputs to, a 600 ohm line. It has a Hi Z, 10k ohm primary impedance and a Lo Z, 600 ohm secondary impedance balanced with a center tap. As an input matching transformer, it may be used to
