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
LOW-IMPEDANCE SELECTION
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.
1. Remove the low-impedance XLR plug by turning the lock screw counter-
clockwise and withdrawing the XLR plug from the case.
