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.
