AUDIO OUTPUT CONNECTIONS
Select the ‘LINE’ position of the ‘LEVEL’ switch when the
output of the receiver is connected to the line level input of
a mixer or amplier. Sele ct the ‘MI C’ position of the ‘LEVEL’
s
witch when the output of the receiver is connected to a
microphone level input of a mixer. Distortion may occur if the
‘LEVEL’ switch is set to the wrong position. (Fig.8)
The ‘BALANCED OUTPUT’ should be used when the receiver
is going to be connected to either a microphone or line level,
balanced input of a mixer. (Fig.9)
Longer runs are less likely to cause problems with balanced
cables.
The ‘UNBALANCED OUTPUT’ should be used when the
receiver is going to be connected to a ¼” input jack of a mixer
or an amplier (usually line level) that uses a ¼” jack. Use the
a
ppropriate setting on the ‘LEVEL’ switch on the rear panel
of the Contact 800T. Cable length for this type of connection
should be limited to less than 15 feet (5 meters). (Fig.10)
