T1 ToneMatch® Audio Engine to Compact
This refers to the connection from a T1 ToneMatch Audio Engine Master or Aux Output using ¼ inch jack connections.
¼ Inch Tip-Ring-Sleeve (balanced) to ¼ Inch Tip-Ring-Sleeve (balanced)
A balanced connection is preferred and will provide better noise rejection over greater distances than the unbalanced connection.
¼ Inch Tip-Ring-Sleeve (unbalanced) to ¼ Inch Tip-Sleeve (unbalanced)
This should work fine but a balanced connection (immediately above) is preferred especially if you will have cable runs in excess of 20 feet (6 meters) or if you hear line noise, hum or hiss.
