CONNECTING TO AN UNBALANCED INPUT AMPLIFIER

A  special  cable  is  required  to  make  this  connection.  This  cable 

connects  pin  1  to  the  shield  and  pin  2  to  the  center  pin.  It  leaves  the 

output pin 3 unconnected.

Connecting  the  unused  output  pin  (usually  pin  3)  to  ground  will 

cause  excessive  ground  currents  and  degrade  performance.  Use  an 

ohmmeter or continuity checker to determine how a cable is wired.
