Line matching transformer

MODEL A95U LINE MATCHING TRANSFORMER

This reversible transformer matches low- or high-impedance microphones to

high- or low-impedance inputs. The transformer permits use of very long micro-

phone cables with either low- or high-impedance microphones. However, when

connecting a high-impedance microphone, limit the cable length between the mi-

crophone and the transformer to 4.6 m (15 ft). The cable from the transformer to

the low-impedance input can be any desired length.

The transformer prevents high-frequency loss, level loss, and pickup of noise

and hum. The A95U comes furnished with a three-pin XLR connector on the

low-impedance end, with a 1/4 in. phone plug and phone jack adapter on the

high-impedance end.

Case

Full magnetic shield, steel with gray enamel finish

Dimensions

19 mm (3/4 in.) diameter; 89 mm (31/2 in.) long without adapters

The A95U comes factory preset with the low-impedance end intended for use

with microphones or inputs rated 75 to 300 ohms. For microphones or input rated

at 19 to 75 ohms, make the following changes.

Remove the low-impedance XLR plug by turning the lock screw counter-

clockwise and withdrawing the XLR plug from the case.
